    Background Although the numbers of malaria cases in China have been declining in recent years, outbreaks of Plasmodium vivax malaria were still being reported in rural areas south of the Yellow River. To better understand the transmission dynamics of P. vivax parasites in China, the extent of genetic diversity of P. vivax populations circulating in Bozhou of Anhui province of China were investigated using three polymorphic genetic markers: merozoite surface proteins 1 and 3α (pvmsp-1 and pvms...

    Damaging earthquakes on faults typically recur at intervals of centuries to millennia but the seismographs that record them have only been around for about hundred years. Complete records of earthquakes of Ms5 or above for Anhui Province of China and its adjacent areas began in 1336 and most previous records were lost. To reduce the hazard from earthquakes we need a longer record of them than can be provided from such instruments. Archaeoseismological evidence has the potential to determine earthquake activity over millennial time spans, especially when integrated with historical documents and geological evidence. In recent years, taking advantage of large-scale civil excavations, our research team including earthquake and archaeological scientists have cataloged, identified, and analyzed deformation relics of the late-Quaternary period, especially the Neolithic Age. Prehistoric earthquake traces were found in the cultural layers of the Western Zhou Dynasty and the Spring and Autumn Period in Southwest Anhui, the late Dawenkou cultural period in North Anhui, and the Eastern Zhou in South Henan. Along the segment of the Tanlu Fault Zone on the border of Jiangsu-Anhui Provinces, several rapid deformation events mainly in the form of oblique translational thrust had occurred since Late Pleistocene, which was confirmed by microscopic studies. The research findings have partly filled the gap of earthquake records in the area and enriched research methodologies in archaeology, prehistoric earthquakes and earthquake prediction. The project was sponsored by China Earthquake Science Special Research Funding Program (#201308012)

    With China's gender imbalance and increasingly severe male marriage squeeze, patterns of intergenerational support in rural areas are likely to undergo significant change. Using data from a survey of four towns from X county in Anhui province carried out in 2008, this article analyzes the effects of sons' marital status on intergenerational support. Random-effect regression analysis shows that son's marital status has strong effects on financial support to and coresidence with parents. Compared with married sons, older unmarried sons (so-called forced bachelors) tend to provide less financial support to their parents and are more likely to live with their parents. Parents' support of sons, as well as the parents' own needs and sons' capabilities all affect the support provided by sons. These results show that both theories of exchange and altruism are simultaneously relevant in the context of the marriage squeeze of contemporary rural China. PMID:26243325

    Full Text Available This study analyzes and evaluates the status and long-term trend of regional economic sustainability in eastern Anhui Province, China. Based on the triangle model and the definition of economic sustainable development, this study evaluates the interrelationship among regional economic development, resource-energy consumption, environmental pollution, and ecological performance. The sustainable and comprehensive utilization situation in the study region from 1975–2012 is examined. The results show that in 2012, the comprehensive development in the study region had a general status in terms of sustainability. The sustainable development trend of the seven administrative subunits inside the region had a weak and general status in terms of sustainability, while the status of sustainability in the southeastern part of the region was better than that in the northwest. During the period from 1975–1998, the study region’s comprehensive development presented a trend of general sustainability. In the period from 1998–2012, the region experienced a trend of very strong sustainability in its development. These statuses and trends have a certain relationship with the study region’s strong economic development and environmental protection over the past 37 years. The triangle method, as an intuitive platform for illustrating sustainability status and trends in economic development, seems to hold promise as an analytical management tool given its simplicity, ease of use, and flexibility.

    Deep coal mines in northern Anhui province,China,provide opportunities for tracing the distribution and fractionation of rare earth elements (REEs) in deep seated environments.Major ions,as well as REE concentrations were measured in groundwater from a sandstone aquifer located between -400 and -280 m.Our results indicate that this groundwater consists of Cl·HCO3-Na or Cl·CO3-Na water types with warm temperature (30.1-31.4℃),circumneutral pH (7.27-8.61) and high levels of total dissolved solids (TDS- 1306-2165 mg/L).Concentrations of REEs in groundwater are high as expressed by their Nd concentrations (0.0086-0.018 μg/L).Except for weak heavy REEs (HREE) enrichment relative to light REEs (LREE),the similarity of REE distribution patterns between groundwater and aquifer rock indicate that enrichment of REEs is considered to be controlled by aquifer rock,as well as by their minerals,whereas the fractionation of REEs is controlled by HREE enriched minerals and,to a lesser extent,by inorganic REE complexes.Ce anomalies normalized to Post Archean Average Shale (PAAS) and aquifer rock are weak,which probably reflect the contribution of reduced conditions in combination with pH,rather than a signature of aquifer rock.

    The aim of this study was to explore infectious diseases related to the 2007 Huai River flood in Anhui Province, China. The study was based on the notified incidences of infectious diseases between June 29 and July 25 from 2004 to 2011. Daily incidences of notified diseases in 2007 were compared with the corresponding daily incidences during the same period in the other years (from 2004 to 2011, except 2007) by Poisson regression analysis. Spatial autocorrelation analysis was used to test the distribution pattern of the diseases. Spatial regression models were then performed to examine the association between the incidence of each disease and flood, considering lag effects and other confounders. After controlling the other meteorological and socioeconomic factors, malaria (odds ratio [OR] = 3.67, 95% confidence interval [CI] = 1.77-7.61), diarrhea (OR = 2.16, 95% CI = 1.24-3.78), and hepatitis A virus (HAV) infection (OR = 6.11, 95% CI = 1.04-35.84) were significantly related to the 2007 Huai River flood both from the spatial and temporal analyses. Special attention should be given to develop public health preparation and interventions with a focus on malaria, diarrhea, and HAV infection, in the study region. PMID:26903612

    Literature review on the status of consumption difference of rural residents and its causation analysis is carried out.Most researches introduce the status and causation of consumption cap in rural residents from different aspects,which mainly analyze the obsolete data from the macroscopic angle by measuring methods.Only a few researches analyze the data in recent years from the provincial angle by using Theil index as the analysis index.Therefore,taking Anhui Province as an example,Theil index is selected to calculate the consumption gap of rural residents in Anhui Province in the years 2003-2008,according to the sample survey of rural households in Anhui Province in the years 2004-2009.Through the analysis of living consumption expenditure of rural residents,consumption change and its various internal causes are studied.Result shows that differentiation change of food and residence consumption expenditure is the major reason for the differentiation change of living consumption expenditure.Proportions of other expenditures are relatively small,having little impact on the living consumption of rural residents.Based on this,suggestions are put forward in order to minimize the difference in living consumption expenditure in rural areas,such as enhancing the income level of middle and low-income family in rural areas,improving the reform of education and health care,and strengthening the construction of rural road.

    Full Text Available A new species of Saurichthys, S. majiashanensis , is described. It comes from a series of marine vertebrate-bearing beds of the upper member of the Nanlinghu Formation outcropping in the large quarry at the top of Majiashan (Majia Hill near Chaohu (Hefei City, Anhui Province, China. Its age is Middle Spathian (Olenekian, Early Triassic. This new species deeply differs from the several pre-Spathian species of Saurichthys mainly for having only two longitudinal scale rows together with a reduced grid-like structure for the neural elements in the vertebral column. Further derived characters are in the endoskeleton of the dorsal and anal fin, where radials articulate only to anterior lepidotrichia, the posterior ones being supported by the first scale from the caudal pedicle mid-dorsal and mid-ventral rows, deeply imbedded in the body. In addition, the haemal spines of the caudal region are much enlarged and reversed, with their distal parts pointing forwards. Though the skull is lacking, postcranial characters are enough to justify the erection of a new species. This new Saurichthys species, together with other few actinopterygians, can be considered as the oldest assemblage of the Triassic Middle Fish Fauna, which bloomed probably in the early Anisian and widespread especially all over the Tethys for the Middle Triassic and at least the Carnian in the Late Triassic. This new fish assemblage, together with some of the oldest marine reptiles, is considered as the beginning of the actual Triassic recovery among marine vertebrates.

    Two surveys were conducted to investigate weed vegetation in a 153-hm2 sampling area of summer crop fields from Anhui Province, China, through visual scoring of the level of weed infestation compared with summer crops on a seven-class scale. In total, 155 sampling sites were selected in the field based on crops, tillage, rotation systems, geographical regions, and soil types across the province. Data on weed communities and environmental factors were collected and analyzed through principal component analysis (PCA) and canonical correspondence analysis (CCA), and the output was interpreted ecologically. Results showed that the main factors influencing the structure and distribution of weed communities in summer crop fields were the soil submersion period, latitude, and soil type and pH. The CCA indicated a significant relationship between weed dominance and soil submersion duration, latitude, and soil pH. From the result of the PCA and CCA ordination, the 155 sampling sites could be divided into three groups based on geographic and floristic composition, as well as weed abundance. The southern dry land group, which was characterized by a double-cropping system in the hilly regions of southern and central Anhui Province with a continuous summer crop and an autumn dry land crop, was dominated by Galium aparine Linn. var. tenerum (Gren. et Godr) Robb., Avenafatua L., and Veronica persica Poir. The northern dry land group, which had the same cropping system as the southern dry land group, was dominated by G. aparine var. tenerun, Galium tricorne Stokes, Descurainia sophia (L.) Schur., and Lithospermum arvense L. in the North Anhui Province, China. These two dry land groups could be combined into one large dry land group, in which the Galium weed vegetation type dominated. The third group was the paddy soil group, which was characterized by a continu ous summer crop and double- or triple-cropping systems of rice, and prevailed in the south and central areas of Anhui

    Full Text Available Abstract Background Hepatitis B is one of the most common infectious diseases in China. The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg among the general population and the risk factors associated with HBV infection in Anhui province, China. Methods A provincial serosurvey was conducted in four cities, and selected through stratified clustering sampling. Data on demographics, immunization history, medical history, family medical history, and life history were collected, along with serum tested for HBsAg. Completed surveys were analysed from 8,875 participants. Results Overall prevalence of HBsAg was 7.44%. Using multivariate analysis, older age was a risk factor for HBsAg infection among children younger than 15 years. Among adults 15-59 years old, the risk factors were male gender, a history of surgical operations, at least one HBsAg-positive family member, and non-vaccination. For adults older than 59 years, the risk factor was a blood transfusion history. Conclusions Though Anhui province has already reached the national goal of reducing HBsAg prevalence to less than 1% among children younger than 5 years, there are still several risk factors for HBsAg infection among the older population. Immunization programs should continue to focus on adults, and interventions should be taken to reduce risk factors associated with being infected with Hepatitis B.

    Full Text Available BACKGROUND: Persistent and heavy rainfall in the upper and middle Huaihe River of China brought about severe floods during the end of June and July 2007. However, there has been no assessment on the association between the floods and infectious diarrhea. This study aimed to quantify the impact of the floods in 2007 on the burden of disease due to infectious diarrhea in northwest of Anhui Province. METHODS: A time-stratified case-crossover analysis was firstly conducted to examine the relationship between daily cases of infectious diarrhea and the 2007 floods in Fuyang and Bozhou of Anhui Province. Odds ratios (ORs of the flood risk were quantified by conditional logistic regression. The years lived with disability (YLDs of infectious diarrhea attributable to floods were then estimated based on the WHO framework of the calculating potential impact fraction in the Burden of Disease study. RESULTS: A total of 197 infectious diarrheas were notified during the exposure and control periods in the two study areas. The strongest effect was shown with a 2-day lag in Fuyang and a 5-day lag in Bozhou. Multivariable analysis showed that floods were significantly associated with an increased risk of the number cases of infectious diarrhea (OR = 3.175, 95%CI: 1.126-8.954 in Fuyang; OR = 6.754, 95%CI: 1.954-23.344 in Bozhou. Attributable YLD per 1000 of infectious diarrhea resulting from the floods was 0.0081 in Fuyang and 0.0209 in Bozhou. CONCLUSIONS: Our findings confirm that floods have significantly increased the risks of infectious diarrhea in the study areas. In addition, prolonged moderate flood may cause more burdens of infectious diarrheas than severe flood with a shorter duration. More attention should be paid to particular vulnerable groups, including younger children and elderly, in developing public health preparation and intervention programs. Findings have significant implications for developing strategies to prevent and reduce health

  17. Geochemical Characteristics of Sedimentary Manganese Deposit of Guichi, Anhui Province, China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The sedimentary manganese deposits occurring in Gufeng formation of the Permian in Guichi area, south Anhui Province, include manganese carbonate deposit formed by sedimentation, and manganese oxide deposit made by later oxidation. The total REE contents of these samples are relatively low ( < 250 × 10-6), belonging to LREE-enriched type,showing LREE enrichment during the process of formation of Mn deposit, especially during Mn-oxidizing process. Three normalized REE patterns and SCNA-normalized trace elements spider diagrams of the Mn-bearing sequence rocks and ores in this area reflect their same origin of ore sources, which is similar to rock-forming and ore-forming conditions. The Mnforming materials primarily came from the continent with higher mature degree and single material source. The δEu and δCe negative anomaly and Ce anomaly ( < - 0.1 ) manifest that Mn-bearing sequence of the Permian was mostly formed in marine basin and oxidative environment. The Sr and Ba anomaly, Sr/Ba and Co/Ni values reflect the Mn deposit environment was of deep water and high-salinity of marine facies. Although the Ce/La (mean 1.05), Y/Ho (25 ~ 41.5) and trace metals show a variety of correlations with Mn in the ten rock samples, which show multiple sources for the manganese, the analysis of geochemical characteristics indicate that the material sources of Mn deposit have been primarily terrestrially derived. Another source of the manganese probably comes from the seafloor volcanism in this area. Analysis of sedimentary features and geohistoric evolvement reveals that the maximum transgression of the Qixia Period, ore district is then in deep shelf-basin sedimentary setting and the Mn-bearing sequence is deposited.

    Assessing and responding to health risk of climate change is important because of its impact on the natural and societal ecosystems. More frequent and severe flood events will occur in China due to climate change. Given that population is projected to increase, more people will be vulnerable to flood events, which may lead to an increased incidence of HAV infection in the future. This population-based study is going to project the future health burden of HAV infection associated with flood events in Huai River Basin of China. The study area covered four cities of Anhui province in China, where flood events were frequent. Time-series adjusted Poisson regression model was developed to quantify the risks of flood events on HAV infection based on the number of daily cases during summer seasons from 2005 to 2010, controlling for other meteorological variables. Projections of HAV infection in 2020 and 2030 were estimated based on the scenarios of flood events and demographic data. Poisson regression model suggested that compared with the periods without flood events, the risks of severe flood events for HAV infection were significant (OR = 1.28, 95 % CI 1.05-1.55), while risks were not significant from moderate flood events (OR = 1.16, 95 % CI 0.72-1.87) and mild flood events (OR = 1.14, 95 % CI 0.87-1.48). Using the 2010 baseline data and the flood event scenarios (one severe flood event), increased incidence of HAV infection were estimated to be between 0.126/105 and 0.127/105 for 2020. Similarly, the increased HAV infection incidence for 2030 was projected to be between 0.382/105 and 0.399/105. Our study has, for the first time, quantified the increased incidence of HAV infection that will result from flood events in Anhui, China, in 2020 and 2030. The results have implications for public health preparation for developing public health responses to reduce HAV infection during future flood events.

    This paper discussed in detail about the REE component and the characteristics of the different kinds of attapulgite clay ores as well as basalts, weathered basalts in four localities of attapulgite clay deposits of Jiangsu and Anhui Provinces of China. It is concluded that the half-weathered basalts have not distinct REE fractionation and strong weathered basalts have HREE loss in the process of the basalts weathered to form smectite group minerals. And the lateritic montmorillonite clays that formed from the basalts weathering have a distinct Ce positive anomaly, a little MREE loss and LREE and HREE renew enrichment. That reflects the particular oxidation condition in the Earth's surface and the adsorption of the colloid solution of the lake water in the basin of the continent in the time of the clays formed. The attapulgite clays produced by the reaction between basalts with lake water in the original place of the basin have same REE characteristics as that of the basalts and the weathered basalts. This shows that REE does not transfer heavily in the progressive chemical weathering process. The sedimentary attapulgite clays have also a similar REE component and characteristic parameters to the basalts and the weathered basalts, and have a distinct Eu negative anomaly and a big value of LREE/HREE, which shows that the sedimentary clay came from the weathered basalts, and REE partitioning patterns characters of the clays are controlled by the residual material of the weathered basalts.

    Helminth infections are believed to be common in tropical and subtropical countries. A cross-sectional study was carried out in two villages located in Guichi District in Anhui Province, the People's Republic of China, where multiparasitism was investigated using parasitological tests. The data collected were fitted to Bayesian multi-level models to profile risk factors for helminth infections. The prevalence of Schistosoma (S.) japonicum, Ascaris (A.) lumbricoides and Trichuris (T.) trichiura were 0.43% (range: 0-0.87% at the village level), 2.28% (range: 1.69-2.88%), and 0.21% (range: 0-0.42%), respectively. No hookworm infection was found. With regard to multiparasitism, only a 33-year-old female was found to be co-infected with S. japonicum and A. lumbricoides. Multiparasitism was unexpectedly rare in the study area, which contrasts with results from other studies carried out elsewhere in the country. The long-term usage of albendazole for individuals serologically positive for schistosomiasis may be the main reason, but this needs to be confirmed by future studies. PMID:26618320

The prevalence of Schistosoma (S. japonicum, Ascaris (A. lumbricoides and Trichuris (T. trichiura were 0.43% (range: 0-0.87% at the village level, 2.28% (range: 1.69-2.88%, and 0.21% (range: 0-0.42%, respectively. No hookworm infection was found. With regard to multiparasitism, only a 33-year-old female was found to be co-infected with S. japonicum and A. lumbricoides. Multiparasitism was unexpectedly rare in the study area, which contrasts with results from other studies carried out elsewhere in the country. The long-term usage of albendazole for individuals serologically positive for schistosomiasis may be the main reason, but this needs to be confirmed by future studies.

    The mites found in stored food and house comprise a large group of subclass Acari, belonging to the suborder Acardida of the order Acarifornes. They can be found in dust and vacuum samples from floors, furniture, mattresses, Chinese herbal medicine, dry fruit, grain, flour, sugar, and bedding. These mites are nidicolous and feed on organic debris, including sloughed human skin, fungi, spilled food, pollen, etc. These mites are particularly prevalent in Chinese herbal medicine, dry fruit, grain, flour, sugar, beds, though carpeted floors near beds or couches may also have large numbers. The most common species are Acarus siro, Tyrophagus putrescentiae , Dermatophagoides farinae , D . pteronyssinus, Glycyphagus domesticus, G. Ornatus, Carpoglyphus lactis and Tarsonemus granarius, etc. The viability of mites in storage is quite strong and they can invade and parasitize the intestines of humans[1 -15]. They can cause pulmonary acariasis[16-25] , urinary acariasis[26-33] and so on. The dejecta of mites is a quite strong allergen and can cause different allergic diseases[34-44]. Intestinal acariasis can be caused by some mites related to the way of diet intake and invading against intestinal mucosa, intestinal muscle[45-5a]. The first report of intestinal acariasis caused by these mites was made by Hinman et al (1934)[45]. From then on, all kinds of studies on the disease have been reported gradually. In order to make an epidemiological survey of intestinal acariasis the investigation of the disease was taken in some areas of Anhui Province from 1989 to 1996.

    The Xinqiao S-Fe-Cu-Au orefield is located in the Tongling ore cluster in the middle and lower reaches of the Yangtze River in East China. There have been many researches regarding the genesis of the Xinqiao orefield in recent years, showing that it belongs to various types, such as sedimentary-reformed type, stratabound-skarn type, sedimentary submarine rocks-hosted exhalative type. We propose that it was formed in two periods of mineralization base on systematic field observation and Pb and S isotopic analyses in nearly ten years. The first period was formed during a syngenetic sedimentary process, whereas the massive sulphide orebodies are mainly related to the Yanshanian granitic magmatism. Sulfide metallic mineral associations show zoning around a granite intrusion, i.e. magnetite and pyrite →pyrite, chalcopyrite and native gold→ pyrite, sphalerite and galena. Gold orebodies occur outside the contact zone of the granite intrusion.

    This study investigated the fluoride present in tea plants (Camellia sinensis (L.) O. Kuntze) and its relationship to soils, varieties, seasons and tea leaf maturity. The study also explored how different manufacturing processes affect the leaching of fluoride into tea beverages. The fluoride concentration in the tea leaves was significantly correlate to the concentration of water-soluble fluoride in the soil. Different tea varieties accumulated different levels of fluoride, with varieties, Anji baicha having the highest and Nongkang zao having the lowest fluoride concentration. In eight different varieties of tea plant harvested over three tea seasons, fluoride concentration were highest in the summer and lowest in the spring in china. The fluoride concentration in tea leaves was directly related to the maturity of the tea leaves at harvest. Importantly, the tea manufacturing process did not introduced fluoride contamination. The leaching of fluoride was 6.8% and 14.1% higher in black and white tea, respectively, than in fresh tea leaves. The manufacturing step most affecting the leaching of fluoride into tea beverage was withering used in white, black and oolong tea rather than rolling or fermentation. The exposure and associated health risks for fluoride concentration in infusions of 115 commercially available teas from Chinese tea markets was determined. The fluoride concentration ranged from 5.0 to 306.0mgkg(-1), with an average of 81.7mgkg(-1). The hazard quotient (HQ) of these teas indicated that there was no risk of fluorosis from drinking tea, based on statistical analysis by Monte Carlo simulation. PMID:27162130

    2015-12-01

    Major ions, trace elements, and isotope concentrations were measured in 11 representative groundwater samples that were collected from a series of aquifers in the Wugou coal mine, Anhui Province. The geochemical characteristics of the groundwater samples were examined using conventional graphical and multivariate statistical approaches, and the results showed that almost all of the groundwater samples collected from the coal-bearing aquifer were the Na-SO4 type, whereas the samples from the Quaternary and the limestone aquifer were the Ca-SO4 and Na-Cl types, respectively. The groundwater in the study area is not suitable for drinking without treatment because of the higher values of total dissolved solids and other parameters, whereas the lower value of the sodium adsorption ratio indicates that it can be used for irrigation. The total rare earth element concentrations ranged from 0.0398 to 0.1874 mg/L, and had an average of 0.075 mg/L. There were negative cerium and positive europium anomalies in the groundwater. The δD and δ 18O values in groundwater ranged from -9.01 to -8.81 ‰, and from -74.7 to -71.4 ‰, respectively. Meteoric water with variable degrees of evaporation is the main source of the groundwater in the coal-bearing aquifer.

    Full Text Available With the strategy shifting from morbidity control to transmission interruption, the burden of schistosomiasis in China has been declining over the past decade. However, further controls of the epidemic in the lake and marshland regions remain a challenge. Prevalence data at county level were obtained from the provincial surveillance system in Anhui during 1997–2010. Spatial autocorrelation analysis and spatial scan statistics were combined to assess the spatial pattern of schistosomiasis. The spatial-temporal cluster analysis based on retrospective space-time scan statistics was further used to detect risk clusters. The Global Moran’s I coefficients were mostly statistically significant during 1997–2004 but not significant during 2005–2010. The clusters detected by two spatial cluster methods occurred in Nanling, Tongling, Qingyang and Wuhu during 1997–2004, and Guichi and Wuhu from 2005 to 2010, respectively. Spatial-temporal cluster analysis revealed 2 main clusters, namely Nanling (1999–2002 and Guichi (2005–2008. The clustering regions were significantly narrowed while the spatial extent became scattered during the study period. The high-risk areas shifted from the low reaches of the Yangtze River to the upper stream, suggesting the focus of schistosomiasis control should be shifted accordingly and priority should be given to the snail habitats within the high-risk areas of schistosomiasis.

    2016-04-01

    There is little information available about the hydrochemical characteristics of deep groundwater in the Linhuan coal-mining district, Northern Anhui Province, China. In this study, we report information about the physicochemical parameters, major ions, and heavy metals of 17 groundwater samples that were collected from the coal-bearing aquifer. The results show that the concentrations of total dissolved solids, electrical conductivity, and potassium and sodium (K(+) + Na(+)) in most of the groundwater samples exceeded the guidelines of the World Health Organization (WHO) and the Chinese National Standards for Drinking Water Quality (GB 5749-2006). The groundwater from the coal-bearing aquifer was dominated by the HCO3·Cl-K + Na and HCO3·SO4-K + Na types. Analysis with a Gibbs plot suggested that the major ion chemistry of the groundwater was primarily controlled by weathering of rocks and that the coal-bearing aquifer in the Linhuan coal-mining district was a relatively closed system. K(+) and Na(+) originated from halite and silicate weathering reactions, while Ca(2+) and Mg(2+) originated from the dissolution of calcite, dolomite, and gypsum or anhydrite. Ion exchange reactions also had an influence on the formation of major ions in groundwater. The concentrations of selected heavy metals decreased in the order Mn > Zn > Cr > Cu > Ni > Pb. In general, the heavy metal concentrations were low; however, the Cr, Mn, and Ni concentrations in some of the groundwater samples exceeded the standards outlined by the WHO, the GB 5749-2006, and the Chinese National Standards for Groundwater (GB/T 14848-93). Analysis by various indices (% Na, SAR, and EC), a USSL diagram, and a Wilcox diagram showed that both the salinity and alkalinity of the groundwater were high, such that the groundwater could not be used for irrigating agricultural land without treatment. These results will be significant for water resource exploiting and utilization in

    Full Text Available The aim of this study was to characterize the prevalence of extended-spectrum β-lactamase (ESBL genes and plasmid-mediated fluoroquinolone resistance (PMQR determinants in 202 Escherichia coli isolates from chickens in Anhui Province, China, and to determine whether ESBL and PMQR genes co-localized in the isolates. Antimicrobial susceptibility for 12 antimicrobials was determined by broth microdilution. Polymerase chain reactions (PCRs, DNA sequencing, and pulsed field gel electrophoresis (PFGE were employed to characterize the molecular basis for β-lactam and fluoroquinolone resistance. High rates of antimicrobial resistance were observed, 147 out of the 202 (72.8% isolates were resistant to at least 6 antimicrobial agents and 28 (13.9% of the isolates were resistant to at least 10 antimicrobials. The prevalence of blaCTX-M, blaTEM-1 and blaTEM-206 genes was 19.8%, 24.3% and 11.9%, respectively. Seventy-five out of the 202 (37.1% isolates possessed a plasmid-mediated quinolone resistance determinant in the form of qnrS (n = 21; this determinant occurred occasionally in combination with aac(6'-1b-cr (n = 65. Coexistence of ESBL and/or PMQR genes was identified in 31 of the isolates. Two E. coli isolates carried blaTEM-1, blaCTX-M and qnrS, while two others carried blaCTX-M, qnrS and aac(6'-1b-cr. In addition, blaTEM-1, qnrS and aac(6'-1b-cr were co-located in two other E. coli isolates. PFGE analysis showed that these isolates were not clonally related and were genetically diverse. To the best of our knowledge, this study is the first to describe detection of TEM-206-producing E. coli in farmed chickens, and the presence of blaTEM-206, qnrS and aac(6'-1b-cr in one of the isolates.

    The Tongshan copper deposit in Anhui Province is a typical mid-sized skarn and porphyry type deposit in the Anqing-Guichi district along the Middle-Lower Yangtze River Valley, eastern China. The Tongshan intrusion is closely related to this mineralization. The intrusion mainly comprises rocks that are quartz diorite porphyry, quartz monzonite porphyry, and granodiorite porphyry. Plagioclase in these rocks is mostly andesine (An = 31.0-42.9), along with minor oligoclase. Biotite is magnesium-rich [Mg/(Mg + Fe) = 0.52-0.67] and aluminum-poor (Al2O3 = 12.32-14.09 wt.%), and can be classified as magnesio-biotite. Hornblende is TiO2-poor ( 0.60], and is magnesio-hornblende or edenite. The SHRIMP zircon U-Pb age of the quartz monzonite porphyry is 145.1 ± 1.2 Ma, which corresponds to the middle Yanshanian period. Whole-rock geochemical results show that the rocks are silica-rich (SiO2 = 60.23-66.23 wt.%) and alkali-rich (K2O + Na2O = 4.97-8.72 wt.%), and low in calcium (CaO = 2.61-5.66 wt.%). Trace element results show enrichments in large ion lithophile element (e.g., K, Rb, and Ba) and depletions in some high field strength elements (e.g., Nb, Ta, P, and Ti). The total rare earth element (REE) content of the rocks is low (ΣREE 10] and small positive Eu anomalies (average δEu = 1.16). These mineralogical, geochronological, and geochemical results show that the intrusion has a mixed crust-mantle source. The Tongshan intrusion was formed by multiple emplacements of crustally contaminated basaltic magma generated by varying degrees of partial melting of enriched lithospheric mantle and lower crust. Hornblende thermobarometry yielded magmatic crystallization temperatures of 652-788 °C and an average crystallization pressure of 1.4 kbar, which corresponds to a depth of approx. 4.7 km. Biotite thermobarometry yielded similar temperatures and lower pressures of 735-775 °C and 0.6 kbar (depth 2.1 km), respectively. The parental magma had a high oxygen fugacity and was

    Anhui Province is divided into 6 zones according to land use. This paper firstly introduces ranges, characteristics and problems of land use zoning in Anhui Province. On these bases, it presents the respective ecological construction mode. Huaibei Plain Zone should focus on agriculture and implement water conservancy project, ecological shelterbelt project and mining subsidence area control works. Jianghuai Hilly Zone should make breakthrough in transforming slope land, speed up restoring forest, grass and vegetation, and implement water-saving agriculture and prevention and control of soil erosion. The Yangtze River Side Plain Zone should take the opportunity of agricultural structural adjustment to implement the ecological construction mode of "reconverting farmland to forests, wetland and lakes". Western Anhui Dabie Mountain Zone should concentrate on setting apart hills for tree growing and transforming slope land, restoring and expanding forest, grass and vegetation, and implementing prevention and control of soil erosion. Southern Anhui Mountain Zone should focus on protecting natural forest, setting apart hills for tree growing, conceding the land to forestry and developing eco-tourism. Residential area should pay close attention to new urbanization construction, center on citizenship of agricultural population, push forward integration of industry and city, coordination of urban and rural areas, and interactive development of primary, secondary and tertiary industries.

An index model for environmental risk assessment of non-point source pollution from fertilization was established and spatio-temporal variation of fertilization and environmental risk of non-point source pollution from fertilization in Anhui was analyzed. Results show that in Anhui of 2013, the total chemical fertilization intensity was 853. 6 kg·hm-2 on average; the environmental risk index of the non-point source pollution from chemical fertilization was 0. 72; the total environmental pollution risk ranked moderate; N :P : K in fertilization was 1 : 0. 52 : 0. 49;the environmental risk index of N, P and K single-element fertilizers was 0. 72, 0. 78 and 0. 65, respectively;the environmental risk of the three kinds of single-element fertilizers ranked moderate, seri-ous and light, respectively;and their spatio-temporal distribution displayed an obvious aggregation effect. In the 16 prefec-ture-leveled cities, the problem of excessive fertilizationin farmlands existed universally. Though varying sharply from region to region in severity, it displayed a specific pattern of distribution. Environmental risk was very serious in Huainan, serious in Bengbu, Lu′an, Wuhu and Tongling, and moderate in the rest of the cities.%为了深入了解化肥施用对农村生态环境的威胁,在综合考虑化肥施用强度、效率、生态安全标准、环境效应权数及作物复种指数等多种因素的基础上,构建了化肥面源污染环境风险评价指数模型,对安徽省化肥施用时空分异与面源污染环境风险进行研究.

    Background Unregulated commercial blood/plasma collection among farmers occurred between 1992 and 1995 in central China and caused the second major epidemic of human immunodeficiency virus type 1 (HIV-1)infection in China. It is important to characterize HIV-1-infected former blood donors and to study characteristics associated with disease progression for future clinical intervention and vaccine development.Methods A cross-sectional study was performed on HIV-1-infected former blood donors (FBDs) and age-matched HIV-seronegative local residents. Demographic, epidemiologic, clinical and key laboratory data were collected from all study participants. Both unadjusted and adjusted multivariate linear regressions were employed to analyze the association of the decrease of CD4+ T-cell counts with other characteristics.Results Two hundred and ninety-four HIV-1-infected FBDs and 59 age-matched HIV-seronegative local residents were enrolled in this study. The unregulated blood/plasma collection occurred more than a decade (10.8- 12.8 years) ago, which caused the rapid spread of HIV-1 infection and the high prevalence of co-infection with hepatitis C virus (HCV, 89.5%); hepatitis B virus (HBV) co-infection was observed in only 11 HIV+participants (3.7%). Deterioration in both clinical manifestation and laboratory parameters and increase of viral loads were observed in parallel with the decrease of CD4+ T-cell counts. The decrease of total lymphocyte counts (P<0.001)and hemoglobin levels (P<0.001) and the appearance of dermatosis (P=0.03) were observed in parallel with the decrease of CD4+ T-cell counts whereas viral loads (P<0.001) and CD8+ T-cell counts (P=0.01) were inversely associated with CD4+ T-cell counts.Conclusions Co-infection with HCV but not HBV is highly prevalent among HIV-1-infected FBDs. CD4+ T-cell counts is a reliable indicator for disease progression among FBDs. Total lymphocyte counts, hemoglobin level and appearance of dermatosis were positively

    The Middle-Lower Yangtze River Metallogenic Belt in the northern Yangtze Block is one of the most important economic mineral districts in China. The Hemushan deposit is a medium-class Fe deposit located in the southern part of the Ningwu iron ore district of the Middle-Lower Yangtze River Metallogenic Belt. The Fe-orebodies are mainly hosted in the contact zone between diorite and Triassic marble. The actinolite-phlogopite-apatite-magnetite ore shows metasomatic/filling textures and disseminated/mesh-vein structures. Based on evidences and petrographic observations, the ore-forming process can be divided into three distinct periods-the early metallogenic period (albite-diopside stage), the middle metallogenic period (magnetite stage and hematite stage), and the late metallogenic period (quartz-pyrite stage and carbonate stage). Fluid inclusion studies show four types of inclusions: type I daughter mineral-bearing three-phase inclusions (L + V + S), type II vapor-rich two-phase inclusions (L + V), type III liquid-rich two phase inclusions (L + V), and minor type IV liquid-phase inclusions (L). Apatites from the magnetite stage contain type I, type II and type III inclusions; anhydrites from the hematite stage mainly contain abundant type II inclusions and relatively less type I inclusions; quartz and calcite from the late metallogenic stage are mainly characterized by type III inclusions. Laser Raman spectroscopy and microthermometry of fluid inclusions show that the ore-forming fluids broadly correspond to unsaturated NaCl-H2O system. From the magnetite stage to the carbonate stage, the ore-forming fluids evolved from moderate-high temperature (average 414 °C), moderate salinity (average 25.01 wt.% NaCl equiv.) conditions to low temperature (average 168 °C), low salinity (average 6.18 wt.% NaCl equiv.) conditions. Hydrogen and oxygen isotopic studies indicate that the ore-forming fluid during the early stage of middle metallogenic period was mainly of magmatic

    Two parallel loess-soil sequences from Xuancheng and Fanchang in southern Anhui Province are dated using geomagnetic and luminescence methods. The Brunhes/Matuyama (B/M) reversal boundary is recognized within the lower part of the so-called Vermiculated Red Soil (VRS) in the Xuancheng section while the entire Fanchang sequence is of Brunhes age. This indicates that the most recent VRS in southern China, a stratigraphic marker and an indication of extremely warm-humid conditions, was formed during the middle Pleistocene, chronologically correlative with the S4 and S5 soil units in northern China. Microscopic and sedimentologic investigations reveal that eolian deposition started in this region at about 0.85 MaBP, roughly synchronous with the well-known Mid-Pleistocene climate change of global significance. The strengthening of both summer and winter monsoon circulations and the consequent river hydrological changes at that time would have provided favorable conditions for sustained eolian deposition in the middle-lower reaches of the Yangtze River since 0.85 MaBP.

The contents of 15 PAHs in carrot, spinach and eggplant were ranged from 23.4 μg·kg-1 to 209.1 μg· kg-1 with the mean level of 120.7μg·kg-1. The quantities of low molecular PAHs(three and four rings) were higher than the high molecular PAHs(five and six rings) detected in vegetables, and three and four rings PAHs were between 92.8% and 94.4% of the total PAHs detected in vegetables. Eight carcinogen PAHs contents were ranged from 11.5 μg·kg-1 to 17.4 μg·kg-1, occupying 9.80% to 13.8% of total PAHs tested in vegetables. The contents of BaP in vegetables were lower than the Chinese standard limits of 5μg·kg-1 in food. The bioaccumulation factors(BAFs) of 15 PAHs in different vegetables were ranged from 0.10 to 9.20, and the highest BAFs of PAHs in vegetables were ten times higher than the lowest one. The BAFs of PAHs in vegetable were in the order of:carrot>spinach>eggplant. The highest BAFs in vegetable were Fle, which was 9.20, 7.07 and 5.48 in carrot, spinach and eggplant respectively. Results from this study provided invaluable data for judging soil quality and vegetable safety in Anhui Province of China.%研究了安徽省合肥、芜湖和亳州市周边蔬菜地土壤和蔬菜中PAHs的含量及其污染特征.结果表明:安徽省典型蔬菜地土壤中15种PAHs(除萘外)的残留总量在58.2~437.8μg·kg-1之间,三环和四环PAHs占PAHs残留总量的70%

    This paper analyses the comparative advantages in 1997-1999 and predicts the near future production trend of 4 kinds of paddy in Anhui and other major producing provinces (including autonomous regions and municipalities directly under the Central Government) in China. Among 5 factors the relative profit from growing rice X is significantly correlative to the ratios of gross paddy yield in 1999 to that in 1997 and in 1992, Y1 and Y2, respectively. However, none of the other 4 factors, i.e., unit yield, gross yield, net output per labour-day from rice-growing, and growers' annual income is significantly correlative to the ratios. The regression equations are calculated to be Y1=0.7800+0.1065X±0.2753 (r=0.4749,P<0.05) and Y2=0.5124+0.3401X±1.9703 (r=0.5344,P<0.02).These equations imply that an increase by 1 in the relative profit will probably result in a 10.65% and 34.01% of increase in the ratio of gross yield in 2 years and in 7 years, respectively. According to mean relative profit in 1998-1999,Hainan, Anhui and Hunan, among 9 major producing provinces in China, have the comparative advantage for production of early long-grained nonglutinous paddy. For semilate long-grained nonglutinous paddy, Yunnan, Guizhou, Henan, Shanxi, Anhui, Sichuan and Chongqing have the advantage among 10 major producing provinces. For late long-grained nonglutinous paddy, Hunan, Anhui, Jiangxi, Zhejiang and Guangxi have the advantage among 9 major producing provinces. For round-grained paddy, Ningxia, Heilongjiang, Jilin, Anhui, Yunnan, Henan, Shanghai, Liaoning, Shanxi, Hebei, and Jiangsu have the advantage among 16 major producing provinces. For different types of rice, an order of the comparative advantage arranged from maximum to minimum is round-grained, semilate long-grained, late long-grained, and early long-grained nonglutinous paddy, which reflects that rice of high quality meets the need in market. In general, rice production in Anhui province has the advantage in China

  9. Uranium Provinces in China

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-lnner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted in the formation of Phanerozoic hydrothermal uranium deposits under extensional tectonic environments. Erosion of uraniferous rocks and pre-existing uranium deposits during the Meso-Cenozoic brought about the removal of uranium into young sedimentary basins. When those basins were uplifted and slightly deformed by later tectonic activity, roll-type uranium deposits were formed as a result of redox in permeable sandstone strata.

    Thirty-three soil samples were collected from the Luling, Liuer, and Zhangji coal mines in the Huaibei and Huainan areas of Anhui Province, China. The samples were analyzed for antimony (Sb) by inductively coupled plasmaoptical emission spectrometry (ICP-OES) method. The average Sb content in the 33 samples was 4 mg kg-1, which is lower than in coals from this region (6.2 mg kg-1). More than 75% of the soils sampled showed a significant degree of Sb pollution (enrichment factors [EFs] 5-20). The soils collected near the gob pile and coal preparation plant were higher in Sb content than those collected from residential areas near the mines. The gob pile and tailings from the preparation plant were high in mineral matter content and high in Sb. They are the sources of Sb pollution in surface soils in the vicinity of coal mines. The spatial dispersion of Sb in surface soil in the mine region shows that Sb pollution could reach out as far as 350 m into the local environment conditions. Crops in rice paddies may adsorb some Sb and reduce the Sb content in soils from paddyfields. Vertical distribution of Sb in two soil profiles indicates that Sb is normally relatively immobile in soils. ?? 2011 Air & Waste Management Association.

    Background and aim The purpose of this study was to describe the characteristics and prevalence of Internet addiction (IA) in adolescents so as to provide a scientific basis for the communities, schools, and families. Methods We conducted a survey by randomized cluster sampling on 5,249 students, grades ranging from 7 to 12, in Anhui province, People’s Republic of China. The questionnaire consisted of general information and IA test. Chi-square test was used to compare the status of IA disorder (IAD). Results In our results, the overall detection rate of IAD and non-IAD in students was 8.7% (459/5,249) and 76.2% (4,000/5,249), respectively. The detection rate of IAD in males (12.3%) was higher than females (4.9%). The detection rate of IAD was statistically different between students from rural (8.2%) and urban (9.3%) areas, among students from different grades, between students from only-child families (9.5%) and non-only-child families (8.1%), and among students from different family types. Conclusion Prevalence of IA is high among Chinese adolescents. IAD has more effect on male students, single-child families, single-parent families, and higher grade students. We should take more care of male students, only-child students, and students living with their fathers, and related education should be strengthen for susceptible subjects of IDA.

    We determined the prevalence and seasonality of infections by Fasciola of goats and bovine species (cattle and water buffalo) in Hubei and Anhui provinces of China. Faecal samples were collected at 2- to 3-month intervals from 200 goats in Hubei province and from 152 bovine species in Anhui province. All faecal samples were examined for the presence of parasites. We determined the nucleotide sequences of the first and second internal transcribed spacers (ITS-1 and ITS-2) of the nuclear ribosomal DNA (rDNA) of 39 Fasciola worms from Anhui province. The prevalence of Fasciola infection in goats ranged between 3.5 and 37.0%, with mean eggs per gram (EPG) ranging between 29.0 and 166.0. Prevalence and EPG exhibited downward trends over time with significant differences. The prevalence of Fasciola infection in cattle ranged between 13.3 and 46.2% (mean EPG, 36.4-100.0), and that of water buffalo ranged between 10.3 and 35.4% (mean EPG, 25.0-89.6), with a higher prevalence of infection and EPG from June to October compared with December to March. Analysis of ITS-1 and ITS-2 sequences revealed that F. hepatica and F. gigantica were present in all bovine species of Anhui province and that F. gigantica mainly infected water buffalo. This is the first demonstration of Fasciola infection in Hubei province and detection of F. hepatica and F. gigantica in Anhui province. The present study of Hubei province shows that mass treatment of livestock with closantel sodium injections in April and August/September controlled Fasciola infection effectively. PMID:26123576

    An important diplogenetic mineralization event superimposed on pre-existing exhalation sediments in the Tongling area, Anhui province, was triggered by widespread granitic magmatism along the northeastern margin of the Yangtze Block during 140-135 Ma under extensional tectonic circumstances following the collision between the North China and Yangtze blocks. The main orebodies of the Dongguashan copper deposit, a typical diplogenetic stratified deposit among many polymetallic ore deposits in China, are hosted by strata between Upper Devonian sandstone and Carboniferous limestone, and its mineralization was genetically related to the Qingshanjiao intrusive. The Rb-Sr isotopic isochron of the Qingshanjiao intrusive yields an age of about 136.5±1.4 Ma. The ore-forming fluid reflected by the inclusion fluid in quartz veins is characterized by high temperature and high salinity, and its age was also determined by Rb-Sr isotope dating as 134±11 Ma. Oxygen and hydrogen isotope composition data suggest that the ore-forming fluid was derived mainly from magmatism. By integrating these isotopic dating data, characteristics of fluid inclusions and the geology of the deposit, the mineralization of the Dongguashan copper deposit is divided into two stages. First, a stratiform sedimentary deposit or protore layer formed in the Late Devonian to the Early Carboniferous, while in the second stage the pre-existing protore was superimposed by hydrothermal fluid that was derived from the Yanshanian magmatic activities occurring around 135 Ma ago. This two-stage mineralization formed the Dongguashan statiform copper deposit.Associated "porphyry" mineralization found in the bottom of and in surrounding intrusive rocks of the orebodies might have occurred in the same period as a second-stage mineralization of this deposit.

    Known as the " food of grain",chemical fertilizer plays a very important role in increasing the output of agricultural products. In the meantime,its negative externalities such as soil and water environment pollutions as well as the quality and safety hazards caused to agricultural products have been revealed gradually. Taking 126 farmer households in 5 counties( districts) of Anhui Province as samples,the fertilizer application behaviors of farmer households are analyzed. Research shows that farmers applying fertilizer are generally older in age with relatively lower degree of education,inveterate farming habits and small area of cultivation. Besides,the farmer households wish to receive training and guidance on techniques of fertilization,but very few of them have attended the trainings on agricultural technology. Moreover,the individual characteristics and family factors of farmer households have a significant impact on their fertilizer application behaviors. And the degrees of impact are also different for the fertilizer applying behaviors in different stages. Therefore,improving the educational level of farmer households,strengthening the training and promotion of agricultural techniques and accelerating land transfer among farmer households will play a fundamental role in regularizing the fertilizer application behaviors of farmer households and improving the quality and safety of agricultural products.

    Objective: To study the Cryptospondium infection among young children in Anhui province, and to explore the best way to diagnose the disease. Methods: Stool specimens of 1204 children were collected; oocysts of Cryptosporidium were identified with auramine O-modified staining, acid-fast staining, safranine T and methylene blue staining, and auramine O-modified acid-fast staining. Results:The detectable rate of Cryptosporidium in four stainings were respectively 2.46%, 1.50%, 1.98% and 3.46%, and there was a higher significant difference in the rate between auramine O-modified acid-fast staining and the others(P < 0.005). The detectable rate was significantly lower in urban children(2.14%, 15/684) than in rural ones(5.19%, 27/520). Boys and girls had similar detectable rate (1.99%, 24/1 204 vs. 1.50%, 18/1 204). Cryptosporidium infection was usually subclinical, and its major clinical features included benign diarrhea, mild abdominal pain and nausea. Conclusion:Cryptospondium infection was relatively common in kindergartens and a higher infection rate was found in rural children. As the majority of the Cryptosporidium infections were subclinical, diagnosis is important although difficult.

    In the future time the exploration of marine oil and gas will be one of the significant domains in China. In this paper the biomarker assemblage characteristics of oilshow in the Nanlinghu Formation of the Majiashan profile, which is located in Chaoxian County, south of Anhui Province, are described in the light of gas chromatography/mass spectrometric (GCMS) analysis on the qualitative and quantitative basis. Based on the investigation of the biomarker assemblage characteristics of possible source rocks developed in the area studied, a conclusion is drawn that the oilshow was generated from the Nanlinghu Formation source rocks (abbreviated as T1n), instead of the Qixia Formation source rocks (abbreviated as P1q). It is pointed out that the T1n is of strong potential for future oil exploration, and therefore much attention should be paid to it.

    2015-03-01

    Heavy metal accumulation in agricultural soil is of great concern, as heavy metals can be finally transferred to the human body through the food chain. A field survey was conducted to investigate the lead (Pb) levels and distribution in soil, agricultural products (wheat, paddy, and soybean), and fish, in the Huainan Coal Mining Area (HCMA), Anhui Province, China, to provide reference information to local inhabitants. The daily intake and target hazard quotients of Pb through food consumption were assessed. Results showed that the mean Pb concentration in soil was higher than the Huainan soil background Pb value but lower than the maximum allowance Pb concentration for agricultural soil (GB 15618-2008). The elevated Pb in soil, especially in rainy months (June to August in Huainan), might be related to Pb leaching from ambient coal gangue piles. Excessive Pb concentration was found in the grains of food crops, which would pose a potential health risk to local inhabitants. Therein, wheat showed higher Pb bioaccumulation ability than other crops. With regard to the Pb levels in muscles, fishes were considered to be safe for consumption. The calculations on daily intake and tolerable hazard quotient of Pb suggest that the potential health hazard posed by Pb is currently insignificant for the inhabitants in the HCMA. PMID:25724617

    The characteristics of the eco-environment,extension scale and sustainable models of converting cropland to forest in the Dabieshan District of Anhui were analyzed. The Dabieshan District is a main ecological area with a function of soil and water conservation where seven large reservoirs and irrigation systems of the Pishihang are distributed. Therefore, the extension scale of converting cropland to forest could be enlarged properly in the reservoir area, while it should be limited in the non-reservoir area due to the issues of higher population density and food safety. Great attention should be paid to the model selection and results during the conversion of cropland to forest. Some suitable models and effective approaches were put forward for the sustainable development in the Dabieshan District, Anhui.

    In order to understand the responses of different types of vegetation in Anhui Province of East China to climate elements, this paper analyzed the recent ten years spatiotemporal variation patterns of the vegetations and their correlations with air temperature and precipitation, based on the monthly Normalized Difference Vegetation Index ( NDVI) data from Moderate Resolution Imaging Spectroradiometer ( MODIS) , the daily temperature/precipitation data from 80 meteorological stations, and the land cover data in 2000-2009. The results showed that in recent ten years, the vegetation index of different land cover types in the Province had different change trends. The vegetation index increased significantly in crop planting area and cities, but had less change in other areas. Forestland had the highest average vegetation index, followed by crop planting area, and then, urban area. The monthly variation of the vegetation index presented a double-peak pattern in crop planting area, but a single-peak pattern for other land cover types.The monthly average NDVI in the Province had a significant positive linear correlation with the monthly mean temperature, and a positive nonlinear correlation with the monthly total precipitation. A threshold value of precipitation existed in its effect on NDVI. There was a weak positive correlation between the NDVI and the inter-annual change of temperature/precipitation. The partial correlation coefficient between vegetation index and air temperature was the maximum in for-estland and the minimum in crop planting area, and was larger in natural vegetation area than in artificial vegetation area. The partial correlation coefficient between vegetation index and precipitation was contrary. In the majority area of middle Huaibei plain and northern Jianghuai ( non-irrigable land) , the vegetation was co-driven by air temperature and precipitation; in some minority middle Huaibei plain grids and water grids, the vegetation was solely driven by

    Impacts of climate variability and climate change are on the rise in China posing great threat to agriculture and rural livelihoods. Consequently, China is undertaking research to find solutions of confronting climate change and variability. However, most studies of climate change and variability in China largely fail to address farmers' perceptions of climate variability and adaptation. Yet, without an understanding of farmers' perceptions, strategies are unlikely to be effective. We conducted questionnaire surveys of farmers in two farming regions, Yifeng, Jiangsu and Qinxi, Anhui achieving 280 and 293 responses, respectively. Additionally, we used climatological data to corroborate the farmers' perceptions of climate variability. We found that farmers' were aware of climate variability such that were consistent with climate records. However, perceived impacts of climate variability differed between the two regions and were influenced by farmers' characteristics. In addition, the vast majorities of farmers were yet to make adjustments in their farming practices as a result of numerous challenges. These challenges included socioeconomic and socio-cultural barriers. Results of logit modeling showed that farmers are more likely to adapt to climate variability if contact with extension services, frequency of seeking information, household heads' education, and climate variability perceptions are improved. These results suggest the need for policy makers to understand farmers' perceptions of climate variability and change in order to formulate policies that foster adaptation, and ultimately protect China's agricultural assets.

    The upper Permian Dalong Formation in the Lower Yangtze Region with black shales is potential for hydrocarbon source rock. Little attention has been paid to this issue. In order to improve the understanding about it, we conducted a comprehensively combined study of petrology and organic geochemistry based on three recently-discovered Dalong black shales outcrops in the southern Anhui province, with the aim to characterize the development and hydrocarbon potential of the Dalong black shales. The results show that the black shales developed widely in all the three outcrops, including the Niushan (Xuancheng City), Caicun (Jingxian County) and Changqiao (Jingxian County). Lithology of the shales is variable from chert to calcareous shale, as well as siliceous mudstone. Stratigraphic correlation and sedimentology of the shales imply that the study area has been subjected to a complete sequence of marine transgression and regression and the black shales generally developed in the environment of deep seawater under reducing, restricted and undercompensated conditions. The results from the study of petrology and organic geochemistry show that the Dalong black shales are rich in organic with the average total organic carbon content being around 2.0%. In terms of kerogen types, the organic matter is primarily Ⅱ2 and Ⅲ. Combined with the high to over maturation of organic matter, we propose that the regional exploration should be focused on natural gas reservoir. Based on the comparison of the distribution of Mesozoic-Cenozoic igneous rocks and black shales in the study area, we infer that the over maturation of organic matter may be primarily influenced by large-scale magmatism in South China during the Mesozoic to Cenozoic period. Thus, petroleum exploration potential can also be considered in the areas where there was no/little significant influence of magmatism (e.g., the Jingxian-Guangde area). These results and understanding can also provide highlights for the

    The Shizishan copper-gold deposit at Tongling, Anhui Province consists of two magmato-hydrothermal mineralization types: the crypto-explosive breccia type and the skarn type. At least four episodes of boiling occurred to the ore-forming fluids in this deposit. The first episode took place in accompany with the formation of the crypto-explosive breccias. The melt-fluid inclusions giving temperatures above 600℃ and salinities higher than 42% NaCl equiv represent a residual magma related to this episode. The second episode occurred during skarnization, giving fluid temperatures of 422℃-472℃, averaging 458℃, and salinities of 10.2%-45.1% NaCl equiv. The third episode corresponds to the main mineralization stage, i.e., the quartz-sulphide stage. Fluid temperatures of this episode vary in a range of 337℃-439℃ with an average of 390℃, and salinities in a range of 3%-30% NaCl equiv. The forth episode happened at the waning stage of mineralization, giving fluid temperatures below 350℃ with an average of 265℃ and salinities of 2.1%-40.4% NaCl equiv.

    Background Intensive blood glucose control is proven to be associated with the diabetic microvascular and macrovascular complications, which could affect quality of life (QOL). This study was performed to determine the effects of intensive glucose control therapy on QOL of elderly patients with type 2 diabetes in Anhui Province.Methods Ninety-seven elderly patients with type 2 diabetes in Anhui were randomly assigned to standard treatment group and intensive therapy group. All patients were followed up for five years on average. Correlated information has been collected during the regular follow-up.Results Patients with microvascular complications reported significantly lower European Quality of Life-5 Dimensions (EQ-5D) scores and had more problems with usual activities, pain and anxiety than those without complications (P <0.05).Patients having experienced hypoglycemic episodes had significantly more problems with anxiety than those without hypoglycemic episodes (P <0.05). No significant difference was detected in all dimensions in quality of life, as well as in Visual Analog Scale score between two groups (P >0.05). There was no significant difference in quality of life at the fifth year compared with that of the first year in both groups. Women had more feelings of pain and anxiety than men (P <0.05)and longer disease course was associated with increased levels of pain and anxiety (P <0.05), as well as with lower QOL.In addition, patients with higher body mass index (BMI) had more problems with daily activities than patients with lower BMI (P <0.05).Conclusions Anxiety is common in elderly diabetic patients and they experienced frequent hypoglycemic episodes.Diabetic vascular complications significantly affect QOL of the patients. Intensive glucose control has no significant effect on QOL of the diabetic patients. Female, older age, long disease course, less education and high BMI are all factors caused reduced QOL and patients with these factors

    2010-01-01

    The abundances of nine major elements and thirty-eight trace elements in 520 samples of low sulfur coals from the Zhuji Mine, Huainan Coalfield, Anhui, China, were determined. Samples were mainly collected from 10 minable coal seams of 29 boreholes during exploration. The B content in coals shows that the influence of brackish water decreased toward the top of coal seams; marine transgression and regression occurred frequently in the Lower Shihezi Formation. A wide range of elemental abundances is found. Weighted means of Na, K, Fe, P, Be, B, Co, Ni, Cr, Se, Sb, Ba, and Bi abundances in Zhuji coals are higher, and the remainder elements are either lower or equal to the average values of elements in coals of northern China. Compared to the Chinese coals, the Zhuji coals are higher in Na, K, Be, B, Cr, Co, Se, Sn, Sb, and Bi, but lower in Ti, P, Li, V and Zn. The Zhuji coals are lower only in S, P, V and Zn than average U.S. and world coals. Potassium, Mg, Ca, Mn, Sr, As, Se, Sb and light rare earth elements (LREE) had a tendency to be enriched in thicker coal seams, whereas Fe, Ti, P, V, Co, Ni, Y, Mo, Pb and heavy rare earth elements (HREE) were inclined to concentrate in thinner coal seams. The enrichment of some elements in the Shanxi or Upper Shihezi Formations is related to their depositional environments. The elements are classified into three groups based on their stratigraphic distributions from coal seams 3 to 11-2, and the characteristics of each group are discussed. Lateral distributions of selected elements are also investigated. The correlation coefficients of elemental abundances with ash content show that the elements may be classified into four groups related to modes of occurrence of these elements. ?? 2009 Elsevier B.V.

    Dogs play an important role in rabies transmission throughout the world. In addition to the severe human rabies situation in China, spillover of rabies virus from dogs in recent years has caused rabies outbreaks in sheep, cattle and pigs, showing that there is an increasing threat to other domestic animals. Two livestock rabies outbreaks were caused by dogs in Shanxi province, China from April to October in 2015, resulting in the deaths of 60 sheep, 10 cattle and one donkey. Brain samples from one infected bovine and the donkey were determined to be rabies virus (RABV) positive by fluorescent antibody test (FAT) and reverse transcription polymerase chain reaction (RT-PCR). The complete RABV N genes of the two field strains, together with those of two previously confirmed Shanxi dog strains, were amplified, sequenced and compared phylogenetically with published sequences of the N gene of RABV strains from Shanxi and surrounding provinces. All of the strains from Shanxi province grouped closely, sharing 99.6 %-100 % sequence identity, indicating the wide distribution and transmission of dog-mediated rabies in these areas. This is the first description of donkey rabies symptoms with phylogenetic analysis of RABVs in Shanxi province and surrounding regions.

    Neisseria meningitidis is a major cause of bacterial meningitis and septicemia worldwide. In China, serogroup A strains were responsible for over 95% of the cases, while serogroup B strains were mainly the cause of localized outbreaks and sporadic cases. Before 2003, serogroup C strains were only re-covered from a few sporadic cases. However, a sudden increase in the number of cases due to sero-group C strains occurred during 2003—2005 in Anhui Province, China. Many cases were found in other provinces at the same time. Multilocus sequence typing (MLST) results indicated that the unique se-quence type 4821 clone meningococci, a new hyper-virulent lineage, was responsible for the serogroup C meningitis outbreaks. We have completed the project of sequencing the whole genome of the Chi-nese N. meningitidis serogroup C representative isolate 053442. We fabricated a whole-genome mi-croarray of N. meningitidis isolate 053442 and analyzed the genome composition differences among 81 serogroup C isolates which were isolated from 14 provinces of China during 1966—2005. The com-parative genomic hybridization (CGH) result shows that the genome compositions of nearly all sero-group C isolates are similar to that of 053442. The products of many absent open reading frames (ORFs) are conserved hypothetical proteins. The results will provide a valuable resource from which one can analyze the genome composition and genetic background of serogroup C meningococci in China.

    Economic value of water and economic analysis of water use management in Gansu Province of China have attracted widespread public attention. With the socioeconomic development, research on water resources has become more important than before. In this study, we define "water productivity" as the changes of economic production outputs of sectoral activities in every cubic meter of water input, which is also the technical coefficient of water resource use in each sector. According to Computable General Equilibrium (CGE) framework, based on the Input-Output Table 2007 and water resources bulletin of Gansu Province, we introduced the water into the ORANI-G (A Generic Single-Country Computable General Equilibrium model) model through the nested constant elasticity of substitution (CES) production function to analyze the changes of economic productions caused by water supply changes. We then examined water productivity in different sectors. Empirical results showed that current water productivity is underestimated. Agricultural water productivity is lower than that of the secondary and tertiary industries, even although agricultural water use is the largest part of water use in Gansu Province, and therefore improving agricultural water productivity can greatly mitigate the water shortage. Simulation results indicate that industrial transformation and development of water-saving industries will also mitigate water scarcity. Moreover, sensitivity analysis shows that the empirical results are robust under different scenarios. The results also show that higher constant elasticity of substitution rate (CES) between water and other production factors will contribute to sustainable development.

    Currently, in Anhui Province, a traditional major province in exporting labor, more andmore migrant workers returning home would like to stay at their hometown, and most of them want to set up their own business. Obviously, the local government should give vigorous aid to these home-going migrant workers. Therefore, Anhui Province could draw on the successful experiences of other provinces for helping the migrant workers returning home, among which include financing, entrepreneurship training and business incubator constructing for the home-going migrant workers. In a word, the government should explore an effective way to offer practical help to the home-going migrant workers both based on the actual state of economic and social development in Anhui, and characterized by the new rural construction.%安徽省是劳务输出大省,当前,由于主客观原因的共同影响,大批农民工返乡并滞留在农村。他们之中有很多人怀有创业愿望,针对这些农民工,政府应该大力扶持。安徽省可以借鉴其他省份扶持返乡农民工创业的经验,并从融资、创业培训、打造农民工创业园等三个方面大力扶持返乡农民工创业。挖掘一条既适合我省农村经济社会发展实情,又具有社会主义新农村特色的农民工创业之路。

    This paper argues that the comprehensive improvement of the rural land has become a major strategic choice to promote industrialization, urbanization and agricultural modernization in Anhui province. The SWOT analysis shows that: Strength includes rich implementation experience, great potential improvement, and solid and deep mass base. Weakness has following aspects:there is no comprehensive target; it is dififcult to achieve equivalence between the rural and the urban; and the progress is hard to balance; compensation standards for destroy the old and build the new is low; and it is also dififcult to relfect the land property rights. Opportunity that is faced with: the state attaches great importance to the comprehensive improvement of the rural land;and it is a moment of great opportunity to advance the whole village; and the construction of ecological civilization and beautiful countryside must be comprehensively promoted. Threats are: cultivated land protection situation remains severe; the contradiction between supply and demand of construction land is still glaring;security measures such as laws and regulations are still deifciency. In response to this, this paper suggests that land reclamation management approach of Anhui province should be published. And integrating zoning with pattern is necessary. In addition, the mechanism of fund safeguard must be improved so as to protect farmers' land property rights.%农村土地综合整治已经成为推进安徽省工业化、城镇化和农业现代化的重大战略选择,运用SWOT分析法,分析得出:优势(S),实施经验丰富,整治潜力巨大,群众基础坚实深入;劣势(W),目标缺乏综合性,乡村与城市难以实现等值化,进展难以均衡,宅就建新补偿标准低,宅基地财产权难以体现;机遇(O),国家高度重视,整村推进时机难得,“生态文明”和“美好乡村”建设全面推进;挑战(T),耕地保护形势

    The 5 provinces in central China have similar economic standard and large educational scale. The overall development level of ICT in elementary education in central China is inferior to medium level in nationwide scope. Besides, there is considerably gap among different provinces and different districts in the same province. Based on the spot check data of 14 districts from the 5 provinces, the paper made comparative analysis on the current situation of ICT development level in elementary education in central China. This signiifcant factors which impact the development of the ICT in elementary education in central China include:(1) The disparities of digital resources become obvious. The vast majority of primary and secondary schools haven’t set up school-based resource center, and the situation of high quality digital resources supported by teaching material has become worse; (2) The recognition degree of the information-based teaching application have been gradually improved. However, the application has not been infused into the link of teaching; (3) The ICT management in elementary education is in the initial stage. The application and popularization of ICT management in elementary education should be reinforced; (4) The ICT development level in provincial capital city and side-provincial capital cities are signiifcantly higher than ordinary city. The difference of ICT development of elementary education among districts is obvious.%我国中部5省经济水平相当,基础教育规模接近且总量较大,基础教育信息化整体发展水平在全国范围内属于中等偏下,省域间、省域内的差异较大。基于中部5省14市(区)的基础教育信息化抽样调查数据,该文对我国中部地区省域间、省域内的基础教育信息化发展现状及其差异性进行对比分析。研究发现影响中部省份基础教育信息化发展的显著因素包括:(1)数字资源整体差异较大,绝大部分中小学校未建

    The regional distribution of export commodities in Anhui Province is at a certain state of imbalance, concentrating mainly on Japan, ASEAN of Asia, Hong Kong, EU of Europe and America of North America. It shows that the export commodities of Anhui Province have less reliance on the traditional target market with the export market being increasingly dispersed. The concentration of the traditional export market is decreasing while the distribution of interior areas is uneven, thus the concentration and distribution of the new market increase correspondingly. In this case, Anhui Province should diversify its export market, taking efficient measures to im- prove the regional distribution of its export commodities.%安徽省出口商品地区分布存在一定程度的不平衡性,主要集中于亚洲的日本、东盟和中国香港地区,欧洲的欧盟和北美洲的美国。这反映出安徽省出口商品对传统出口目标市场依赖程度降低,出口市场日益分散化。传统市场出口集中度下降,但内部地区分布不均匀;新兴市场出口集中度和均匀度均提高。为此,安徽省需要深化出口市场多元化战略,采取切实可行的措施,优化出口商品地区分布。

    Research on amphibian and reptile was made in the Linan Nature Reserve from July 1998 to October 2000. There were 19 species of amphibian (belonging to 7 families,9 genera) and 32 species of reptile (belonging to 9 families,23 genera). They amounted to 48.6% of the total amphibian and reptile in Anhui Province. However,they only occupied 0.021% of the area of the province. 16 species of them have been listed in the "China Red Data Book of Endangered Animals". Faunal specification showed that 76% of the whole were Oriental Realm elements; 24 % were cosmopolitan species; and no Palaearctic Realm elements were found (not including one unidentified species). Unfortunately,these amphibians and reptiles were facing great danger due to illegal hunting. Thus,the authors suggested a research on the sustainable use of natural resources be carried out,together with making more efforts on its conservation and strict control of illegal hunting.%1998年7月至2000年10月,对岭南自然保护区进行了两栖爬行动物调查,发现有两栖动物19种(隶属7科9属),爬行动物32种(隶属9科23属),占安徽省两栖爬行动物种数的48.6%,而面积仅为全省的0.021%,被列入中国濒危动物红皮书的有16种之多。区系特点:东洋界成分占76%,东洋界古北界广布种占24%,无古北界成分(未定种一种不算在内)。非法捕捉已使这里的两栖爬行动物生存面临极大的威胁,建议在加大保护的宣传力度和严厉打击不法分子的同时,积极开展资源可持续利用的研究。

    A preciously undescribed Lower Triassic sequence of a series of multiple cycles of mud-lime rocks, with the argillaceous content decreasing upward while limestone becomes the dominant lithology in the upper part, contains abundant fossils such as conodonts, ammonoids and bivalves. The Yinkeng Formation is the oldest Triassic unit represented, and it conformably overlies dark-gray thin-bedded argillaceous silicalite and intercalated grayish illite clay interbeds of the Upper Permian of Dalong Formation.Conodont samples collected from west Pingdingshan Section, one of four measured sections in Chaohu,yielded abundant Lower Triassic conodonts from the middle part of the Yinkeng Formation. Most interesting and unusual is the abundant occurrence of Platyvillosus in seven samples from the FlemingitesEuflemingites bearing (Smithian) mudstone, rhyolitic clay and limestone part of the section. The associated conodonts are Neospathodus dieneri type 1, N. dieneri type 2, N. dieneri type 3, N. cristagalii, N. waageni eowaageni (nov. subsp. ), N. waageni elongata (nov. subsp. ), N. waageni waageni,N. sp. G (nov. sp.), N. sp. L (nov. sp.), N. sp. H (nov. sp.), N. alberti, N. novaehollandiae,N. peculiaris, N. aff. discretus, N. conservativus, Parachirognathodus sp. and ramiform elements.The species Platyvillosus, which is restricted to a 1. 32 m interval, reveals great variety in shape and denticle ornamentation pattern on the platform. The morphological study of the samples indicates that all speciemens with denticles on the upper surface can be included in intraspecific variation in Platyvillosus costatus (Staesche). Platyvillosus hamadai (Koike), marked by smooth upper surface, also appears to be connected by transitional forms in some samples. The fauna corresponds closely with that of the Taho limestone in Japan, although the depositionai environments differ. The associated lithologies of the Yinkeng Formation within Chaohu area reflect a deeper and iow energy remaining basin of the northern edge of the Lower Yangtze block.

    We used the maps of urban land-use in 1978, 1991, 1994, 2000 and 2004, and softwares such as ArcGIS, Fragstats to analyze the spatio-temporal process of urban residential space quantitatively. Some methods, such as direction analysis and landscape pattern analysis, were employed. The results show that: 1) the residential land grew very rapidly in Hefei from 1978 to 2004, and the increased land was distributed mainly in the central city zone surrounded by a moat; however, after 1994, it was distributed mainly outside the 1th Ring Road; 2) the expansion speeds were very different in different directions: there exists a fastest expansion of residential land in the directions of NE-NNE, SW and SSE, and a slowest one in the directions of E and SEE; 3) the residential land growth went through four stages: slow circular expansion in 1978-1991, 'axes + fan wings' expansion in 1991-1994, more rapid circular expansion in 1994-2000 and 'fan-wings' expansion in 2000-2004; 4) the expansion intensity was also different in all directions in the period of 1978 to 1994, and the most was in SW and then NW; and 5) there were more and more residential land area, and the spatial agglomeration was improved increasingly.

    Major elements, trace elements and sulfur, oxygen isotopic compositions of the main intrusions were studied in Yueshan area. The fact that intrusions enriched in Th and Sr, and depleted in Rb and Ba in this area, suggests that the original magma roots in alkali basalt magma of upper mantle, with deep characteristics. It can be seen that the diagenesis environments are the island arc and active continental margin areas from the lgτto lgσdiagram of intrusions. With the increase of SiO2, Fe2O3, MnO and P2O5 decrease, which shows that the magma of Yueshan area endured crystal fractionation of ferromanganese mineral and apatite in early evolution stage. With the further rise and evolution of magma, magma composition of calcium increased, meanwhile enriched in Zr, and depleted in Nb and Ta. This indicates that crustal component is gradually added, the assimilation and contamination occur between magma and crustal material, which includes the magma evolving, from calc-alkaline series to alkaline series. The results show that crystal fractionation, assimilation and contamination are the main evolution law of magma in this area.

    Industrial structure of Anhui province and its relative superiority alteration was calculated and analyzed by using methods of location quotient and structural coefficient analysis on correlative statistical data. The results indicated that the sections which had relative superiority were distributed in light industrial, excavation industry and material industry. The change trend of industrial structure of Anhui province in the whole was as follows: light industry was a specialized predominance department but its superiority was declining; processing industry was an interior department and its status still went down since 1990s; excavation and material industries were traditional dominance departments and they were still an important support to the development of Anhui industry even though some fluctuation appeared sometimes. The relative status of different business line in Anhui province have changed after entering the 21st century, such as the status' promotion of processing industry,especially manufacturing industry of traffic equipment, which had replaced the position of textile industry and became the biggest business line in output.%采用区位熵法和结构系数变动分析法,运用相关统计资料对安徽工业结构及相对优势变动进行计算分析和研究.结果表明:安徽省工业的相对优势部门主要分布在轻工业、采掘和原料工业.安徽省工业结构整体变动趋势:轻工业是专业化优势部门,但优势在弱化;加工业是安徽的劣势部门,90年代以来相对地位还在下降;采掘和原料工业是传统优势产业,虽然位置波动较大,但仍然是安徽省工业发展的重要支撑.进入新世纪后,安徽省行业相对地位发生了的变化,加工部门的一些行业位置提升较快,最明显的是交通运输设备制造业取代了纺织业成为产值占工业总产值比例最大的行业.

In this study, we randomly selected 10 weedy rice accessions from 10 plots in Jiangsu, and then sequenced the full lengths of theirRcgenes (approximately 6.4 kb). In addition, we collected 166 different full-lengthRc genes in theOryzagenus from the literature and from GenBank. A collinearity sequence analysis showed that the 10 weedy riceaccessions from Jiangsu all had the same wild-type allele of theRcgene. Single nucleotide polymorphisms indicated thatthe nucleotide polymorphisms (π= 0.19) and theproportion of segregation sites(θw= 0.28) of theRcgenes in the 10 weedy rice accessions from Jiangsu were higher than those in 56 weedy rice accessions from USA (π= 0.09 andθw= 0.07). Haplotype and phylogenetic analyses showed thattheRcgenes of weedy rice accessions from Jiangsu were not revertants of therc gene found in Asian cultivated rice(O. sativa) varietieswith white pericarp. In addition,Rcgene sequences of the rice varieties Lvdao from Lianyungang, Jiangsu and Tangdao from Anhui were more similar to those of cultivated rice than to the weedy rice from Jiangsu. These findings support the continued quarantine of weedy rice and clarify the evolutionary mechanism of the red pericarp found in the weedy rice of Jiangsu.

    without increasing the resource input; 3) It is not proper to increase the integrated output by increasing the resource input. The former two states are comparatively reasonable. The second state is especially fit the needs of saving resources in agriculture production and the requirement of sustainable agricultural development. By contrast with the former two states, the third state means that it is the right time to change the mode of local agricultural production. Using the data in Anhui statistical yearbook 2003 and 2009 and the above methods, we also studied the effect of resource input on output increase in agriculture production of Anhui province. The results indicate that from the perspective of the effect of resource input in specific area, increasing the resource input brings the increase of integrated agriculture output in Bozhou, Lu' an, Wuhu, Chizhou and Huangshan, but negative increase in Hefei, Huaibei, Suzhou, Bengbu, Fuyang, Xuancheng and Tongling. From the perspective of resource input, the marginal utilization efficiencies of irrigation, chemical fertilizer, agricultural pesticide and the control of soil erosion are higher and the utilization states of these resources in most areas of Anhui accord with the former two states. However, the marginal utilization efficiencies of agricultural machinery, electricity consumption, the irrigated area with saved water and the plastic films for farm use are lower and the utilization states of these resources accord with the third state.

    Anhui Province lies in the transitional area between temperate zone and subtropical zone, so the climate here is warm and moist, and the four seasons are distinct. The north of the Huaihe River possesses a half-moist monsoon climate of warm temperate zone while the south of the Huaihe River possesses a subtropical moist monsoon climate. As a result, the climate is very suitable for various kinds of crops and plants. On the other hand, many kinds of natural disasters, such as drought, flood, and cold happen frequently every year in Anhui Province, influencing agriculture, ecosystem and people living significantly.Land vegetation and surface temperature play important roles in climate change, resource and environment change, agricultural monitoring and so on, while their in-situ investigation is very limited. Fortunately, satellite remote sensing is used widely to monitor macroscopical, large-scale, dynamic continuous vegetation and surface temperature during recent years. Using MODIS data from 2001 to 2008, seasonal,monthly and spatial variability of normalized difference vegetation index (NDVI) and land surface temperature (LST) of Anhui Province are explored. Furthermore, the relationship between NDVI and LST is analyzed. Also, spatiotemporal variability of NDVI and LST in 4 cities of Anhui Province are analyzed. The results show that spatiotemporal variability of NDVI and LST in Anhui Province are obvious. Due to local climate, the differences of vegetation lead to different seasonal changes and spatial distribution characteristics of LST in Anhui. For instance, due to evergreen broadleaf forests in South Mountain area and Dabie Mountain area, both NDVI and LST seasonal variations are smaller and they are positive correlated. However, in the north and middle most areas, the deciduous broad-leaved vegetation and seasonal crops (rice,wheat, corn, soybean, rape, etc. ) have greatly enlarged the seasonal variations of NDVI and LST, and their positive correlation is

    Full Text Available Hubei Province is the hub of communications in central China, which directly determines its strategic position in the country’s development. Additionally, Hubei Province is well-known for its diverse landforms, including mountains, hills, mounds and plains. This area is called “The Province of Thousand Lakes” due to the abundance of water resources. Geographical names are exclusive names given to physical or anthropogenic geographic entities at specific spatial locations and are important signs by which humans understand natural and human activities. In this study, geographic information systems (GIS technology is adopted to establish a geodatabase of geographical names with particular characteristics in Hubei Province and extract certain geomorphologic and environmental factors. We carry out landscape analysis of mountain-related geographical names and water-related geographical names respectively. In the end, we calculate the information entropy of geographical names of each county to describe the diversity and inhomogeneity of place names in Hubei province. Our study demonstrates that geographical names represent responses to the cultural landscape and physical environment. The geographical names are more interesting in specific landscapes, such as mountains and rivers.

    A model of phosphorus purification in a watershed was established based on the export coefficient and purification index of phosphorus in different types of land cover. The model was employed to simulate the economic value of the ecosystem service with the expected water quality standard and marginal cost of pollutant purification of the upper reaches of Xin' an River of Anhui, China. The results revealed that from 2000 to 2010, some farmland outside the Tunxi, Jixi, Shexian, Yixian and Xiuning was converted to built-up land. The total amount of phosphorus exported to the upper Xin' an River decreased a little, and the main source of phosphorus pollution was farmland and built-up land. More than half of the exported phosphorus was efficiently purified by different types of land cover via flow accumulation. The pattern of purification and export of highly concentrated phosphorus showed the same trend which occurred in the northern part of the watershed including the Yangzhi River, Fengle River and Hengjiang River. Forestland and grassland did not efficiently purify phosphorus in the watershed owing to the irrational distribution of existing land cover. The total service value was 3.80 and 3.31 million Yuan in 2000 and 2010, respectively. PMID:26259471

  15. Nodes and Field of Tourist Origins to Ancient Village——A Case Study of Huangcheng Village in Shanxi Province of China

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Based on Hagget's theory of spatial structure, researches on the nodes and field of tourist origins to Huangcheng Village in Shanxi Province of China have been explored. Nodal hierarchy structure of tourist origins is analyzed with cluster analysis and the gravity model. And field of tourist origins is analyzed with attraction radius index (R) and geography concentration index (G). In the field analysis, R and G of Huangcheng Village are compared with Xidi Village that is a world heritage located in Huangshan City of Anhui Province in China. According to comparison of locations of two areas, influential factors for field area of Huangcheng Village are identified. It is concluded that: 1) cluster analysis and gravity model can be complementary methods to each other for nodal hierarchy structure analysis of tourist origins; and 2) as far as location is concerned, the weak intensity effect of tourism resources in the tourist region is a major cause for explaining why tourist origins to Huangcheng Village are mainly its neighboring areas. Moreover, it is suggested that the regional effect of tourist resources should be regarded as a component of destination attractiveness when applying gravity model.

    Located in the north and south transition zone, Anhui province has been experiencing disasters featuring high frequency, great harm, and alternating periods of droughts and floods predominating. The problems of the current implementation of Anhui agricultural risk management lie in the weak basis for its agricultural risk management, the government' s limited invested capital, the inadequate spending on agricultural infrastructure, and the imperfect market risk management system, so it is suggested that the ability of agricultural risk management should be enhanced in perfecting the agricultural risk management system, improving the government' s investment system in this field, developing market system, consolidating agricultural infrastructure construction, strengthening peasants' disaster risk management awareness as well as accelerating the creativity of agricultural risk management tools.%安徽省地处南北过渡带,气象灾害呈现出频度高、危害大、以旱涝灾害为主导且交替出现等特点。当前安徽省实施农业风险管理存在着农业风险管理基础薄弱、政府投入资金有限、农业基本设施投入不足、市场化的风险管理体制尚未完善等一些问题,提出应从完善和健全农业风险管理体系、进一步加强政府农业风险管理的投入机制建设,积极发展市场机制、加强农业基础设施建设、提高农民灾害风险管理的意识、加快农业风险管理工具的创新等多个方面提高农业风险的管理能力。

    根据安徽省1994年—2012年的样本数据,运用Cobb-Douglas生产函数理论模型,对税种结构变动与经济增长关系进行实证分析。结果表明:增值税占总税收比重的增加会降低人均生产总值,营业税、企业所得税、个人所得税、农业各税占总税收比重的增加会提高人均生产总值,资源税的经济效应不显著。因此,应该进一步优化现行税制结构:有序推进“营改增”,完善中央与地方的税收分享体制;提高所得税的比重,增强其收入再分配作用;加快推进资源税改革,促进经济可持续发展;适度调节农业各税,培育农村大市场。%This paper, using Cobb-Douglas production function, makes an empirical analysis of the relationship be-tween tax structure change and economic growth based on the data of Anhui province from 1994 to 2012 . The re-sults show that the growth of the share of value-added tax will reduce output per capita;the growth of the share of business tax, corporate income tax, individual income tax and agricultural tax will raise the output per capita;the economic effects of resource tax are not significant. Therefore, Anhui needs to further improve tax system, change business tax to value-added tax orderly, improve the sharing system of tax income between central government and local government, increase the proportion of income tax and strengthen its effect of income redistribution, accelerate the reform of resource tax, and adjust agricultural tax appropriately and cultivate rural market.

    Telemedicine has become an increasingly popular option for long-distance health care and continuing education. As information and communication technology is underdeveloped in China, telemedicine develops slowly. At present, telemedicine consultation centers are situated mainly in developed cities, such as Beijing, Shanghai, and Guangzhou. In many less developed regions, such as northwest China, the conditions or related facilities are not available for the application of a better medical service. Accordingly, the aim of this paper was to introduce the construction and application of a telemedicine consultation center in Gansu Province in the northwest of China. In addition, the function of Gansu Provincial Telemedicine Consultation Center on emergency public events was introduced. As a whole, there was a great demand for telemedicine service in the local medical institutions. In the telemedicine consultation center, the telemedicine equipments and regulations were needed to be improved. The function of telemedicine service was not fully used, there was a large space to be applied and the publicity of telemedicine service was important. What is important was that telemedicine played a significance role in promoting the medical policy reform, improving the medical environment and launching the remote rescue in the emergency public events. This paper emphasizes the health care challenges of poor regions, and indicates how to share the high-quality medical service of provincial hospitals effectively and how to help residents in resource-poor environments.

The Gymnastics and Fencing Center of Anhui Provincial Sports Administration is in charge of operations. Various municipal governments are in charge of administration. The appropriate coordinating mechanism is not established and there is the lack of necessary communication. The competitive gymnastics training in Anhui Province fails to receive the due attention. It is short of medium-term and long-term developing programs, funds and the coach team. These problems restrict the quality of the competitive gymnastics training in Anhui Province. The suggestion is that the Gymnastics and Fencing Center of Anhui Provincial Sports Administration should set up mechanism of communication with each municipal government, draw up the plan for the medium-term and long-term development of the grass-roots training spots, increase the funds, and expand the funding

    Background This research aims at identifying relative interventions on trachoma and testing the effectiveness of control measures adopted by assessing its prevalence and related risk factors in Shandong province of China.Methods Trachoma rapid assessment (TRA) was conducted in 6 sub-districts selected from Shandong province based on primary high risk assessment.Active trachoma in children aged 1-9 years and environmental risk factors of trachoma (unclean faces,absence of running water,and absence of flush toilets) were assessed (TRA 1).Control measures were taken in endemic areas.A second TRA (TRA 2) was conducted after 12 months in the same 6 districts and findings of the two TRAs were compared.Results In TRA 1,we found trachoma in 3 sub-districts and the detection rate was 4% (95% Cl:0.39%-11.12%),6% (95% Cl:1.18%-14.17%),and 6% (95% Cl:1.18%-14.17%) respectively.We could not find trachoma cases in TRA 2.Research data supports that children living with environmental risk factors face an increased risk to active trachoma.However,we could not find statistical evidence for this association,which may be caused by the limited data on prevalence.Conclusions This research indicates that the TRA methodology is easy to assess trachoma and its related risk factors.Based on the results of this study,we have already achieved the goal of "elimination of trachoma" in Shandong province,as the detection rate of trachomatous inflamation follicular/trachomatous inflammation intense in 1-9-year-old children was less than 5%.

    AIM: To estimate the mortality rates of gastroenterologic cancers for the period between 1974 and 1999, in Henan Province, China and its epidemiologic features.METHODS: Information on death of patients with cancer was provided by the county-city registries. Population data were provided by the local police bureau. All the deaths of cancer registered were classified according to the threedigit rubric of the ICD-9. Cancer mortality rates reported herein were age-adjusted, using the world population as standard and weighted piecewise linear regression analysis.RESULTS: Total cancer age-adjusted mortality rates were 195.91 per 100 000 for males and 124.36 per 100 000 for females between 1996 and 1998. During the period of 19741999, a remarkable decrease took place in esophageal carcinoma, stomach cancer remained essentially stable and liver cancer, a moderate increase. Colorectal cancer was slightly increased over the last two decades.CONCLUSION: The population-based cancer registry can give an accurate picture of cancer in Henan Province, by providing a set of analyses of selected cancer mortality data as a source of reference for researchers in cancer, public health and health care services.

    To summarize the changing epidemiological characteristics of malaria in Zhejiang Province, China, we collected data on malaria from the Chinese Notifiable Disease Reporting System (NDRS) and analyzed them. A total of 2,738 malaria cases were identified in Zhejiang Province from 2005 to 2014, of which 2,018 were male and 720 were female. Notably, only 7% of malaria cases were indigenous and the other cases were all imported. The number of malaria cases increased from 2005 to 2007, peaked in 2007, and then decreased from 2007 to 2011. There were no indigenous cases from 2012 to 2014. Of all cases, 68% of cases contracted Plasmodium vivax, 27% of cases contracted P. falciparum, and two cases contracted P. malariae. About 88% of malaria cases during 2005-2011 occurred yearly between May and October, but the number of malaria cases in different months during 2012-2014 was similar. The median age was 33 years, and 1,892 cases occurred in persons aged 20-50 years. The proportion of businessmen increased and the proportion of migrant laborers decreased in recent years. The median time from illness onset to confirmation of malaria cases was 5 days and it decreased from 2005 to 2014. Some epidemiological characteristics of malaria have changed, and businessmen are the emphases to surveillance in every month. PMID:26078321

  18. Mercury distribution in coals influenced by magmatic intrusions, and surface waters from the Huaibei Coal Mining District, Anhui, China

    International Nuclear Information System (INIS)

    Highlights: • Hg concentrations in coal and surface water samples were determined. • Hg is enriched in the Huaibei coals. • Magmatic activities imparted influences on Hg content and distribution. • Hg contents in surface waters are relative low at the present status. - Abstract: The Hg concentrations in 108 samples, comprising 81 coal samples, 1 igneous rock, 2 parting rock samples and 24 water samples from the Huaibei Coal Mining District, China, were determined by cold-vapor atomic fluorescence spectrometry. The abundance and distribution of Hg in different coal mines and coal seams were studied. The weighted average Hg concentration for all coal samples in the Huaibei Coalfield is 0.42 mg/kg, which is about twice that of average Chinese coals. From southwestern to northeastern coalfield, Hg concentration shows a decreasing trend, which is presumably related to magmatic activity and fault structures. The relatively high Hg levels are observed in coal seams Nos. 6, 7 and 10 in the southwestern coal mines. Correlation analysis indicates that Hg in the southwestern and southernmost coals with high Hg concentrations is associated with pyrite. The Hg concentrations in surface waters in the Huaibei Coal Mining District range from 10 to 60 ng/L, and display a decreasing trend with distance from a coal waste pile but are lower than the regulated levels for Hg in drinking water

    Coal mining area is highly subject to lead (Pb) pollution from coal mining activities. Several decades of coal mining and processing practices in dozens of coal mines in the Huainan Coal Mining Area (HCMA) have led to the accumulation of massive amounts of coal gangue, which piled in dumps. In order to investigate the impacts of coal gangue dumps on Pb level in the supergene media of the HCMA, a systematic sampling campaign comprising coal gangue, soil, wheat, and earthworm samples was conducted. The average Pb content in the coal mining area soil is 24 mg/kg, which is slightly higher than the associated coal gangues (23 mg/kg) and markedly higher than reference region soil (12.6 mg/kg). Soil in the HCMA present a slight to moderate Pb contamination, which might be related to the weathering and leaching of coal gangue dumps. Lateral distribution of Pb in HCMA soil differed among individual coal mines. The soil profile distribution of Pb depends on both natural and anthropogenic contributions. Average Pb content is higher in roots than in stems, leaves, and wheat husks, while the Pb level in seeds exceeded the maximum Pb allowance for foods (Maximum Levels of Contaminants in Foods of China, GB 2762-2012). Earthworms in the selected area are significantly enriched in Pb, suggesting higher bio-available Pb level in soil in the HCMA. PMID:24756412

    论文对安徽淮北地区69个地下水位站的1980-2006年平均地下水埋深资料进行分析,得出淮北地区多年平均地下水埋深2.33 m,1980-1990年各地下水年均埋深较浅、变幅较小,1990年以后地下水埋深变幅加大,且埋深有明显的加深趋势.研究认为淮北平原地下水动态虽然受降水量、蒸发量和人类活动等多种因素影响,但近些年来地下水的动态变化主要是人类活动影响的结果.这些人类活动包括地下水资源开发利用、土地利用、水利工程、农业节水灌溉措施等.其中过度开发利用地下水是导致安徽淮北平原地下水埋深下降、地下水资源减少的主要原因.适度开发利用地下水有利于淮北地区地下水的循环更新,但过度的开发利用,已造成平原北部开始出现严重的环境地质问题,应限制开采.%Huaibei alluvial plain lies in the middle reach of the Huaihe River basin and the main part of the plain is in Anhui Province. In this region, human activities are intense and water pollution is still serious, so people have to use much groundwater. This article analyzed the annual mean groundwater burying depth from 1980 to 2006 from 69 water table stations on Huaibei alluvial plain, Anhui Province. The authors concluded that multi-annual mean groundwater burying depth is 2.33 m in this region. The annual mean groundwater burying depth was shallow and changed little during the 1980s, but it changed greatly and was apparently deeper after 1990. Although groundwater dynamic is affected by precipitation, evaporation and human activities, the change was the result of human activities in recent years in Huaibei alluvial plain. These activities include groundwater exploitation, land use, hydraulic engineering and agriculture water-saving irrigation measure, and groundwater overexploitation was the main reason for water table decline and groundwater resource decrease. Moderate use of groundwater is

    Based on the road network maps in 1996, 2004, and 2010, choosing weighted average travel time as an indicator, the spatial pattern and evolution of major cities' road accessibility in Anhui Province are studied. Results are shown as follows: In the study period (1996-2010), the spatial structure of accessibility in Anhui Province shows little change; Hefei area is the center with the lowest accessibility level; the value increases from the center to the surrounding areas, and its distribution is alongside with the directions of traffic arteries. The improvement of road networks greatly increases the accessibility of major cities in the region, and the acces- sibility increase in the first period (1996-2004) is greater than that in the second period (2004-2010). The extent of accessibility change is related to the initial level. In the first period, the rate of the accessibility change decreases from the "T-shaped" region, covering the areas along the "Xu-He", "He-Wu-Xuan" highway and the Yangtze River, to periphery areas. However, the second period sees a multi-core spatial pattern in which the rate of accessibility change decreases from the areas with newly constructed highways to the surrounding areas. Dif- ferent areas benefit from the access to the road network differently, with Jiangnan area benefiting the most, Huaibei and Jianghuai areas the second. With the improvement of road networks, the accessibility gets optimized from a center to periphery in layered circles with the accessibility levels evenly and smoothly distributed. Among the cities, the difference of accessibility gradually narrows, and accessibility coefficient gradually reaches an equilibrium distribution.%以1996、2004、2010年为时间断面,加权平均旅行时间为指标,探讨安徽省公路网络中节点城镇可达性空间格局及其演化规律。结果表明:1996-2010年,安徽省公路网络可达性总体空间格局变动不大,其值大体以合肥地区为中心向外围

    The analysis on intercity relationship and regional spatial structure from the perspective of passenger flow of long-distance coach travel is an important approach to provincial spatial structure studies.Daily passenger flow of long-distance coach travel is a significant part of passenger flow among cities which can reflect functional intercity relationships and reveal the inner-provincial spatial relationship clearly.Based on the daily passenger flow of long-distance coach travel,in this article,Anhui Province is taken as an example.The characteristics of intercity relationships and spatial structure of Anhui Province is explored.To examine the characteristics of intercity relationships and spatial structure of Anhui Province,the research data are analyzed from two aspects.1) The intensify characteristics of the intercity passenger flow.Passenger flow is graded according to the numerical size,then the passenger characteristics of traffic flow in different regions are analyzed in this article,especially focusing on relationships between the provincial capital(Hefei) and other cities in this province.2) The structural characteristics of intercity passenger flow.According to directions of the largest passenger flow and the second largest passenger flow,the overall trend and spatial structure of the daily population movements among cities are analyzed,and the provincial nodes in the urban network from the perspective of topological characteristics and the flow strength on the city level are examined in this article.The conclusions are as follows: 1) On the whole,Anhui Province presents a mono-center structure,and the inter-regional links between cities are relatively weak except the center city(Hefei);Hefei affects and maintains frequent contact with Chaohu directly,Lu'an and Huainan.There seems to be a high possibility that these three cities would become a major part of the metropolitan area of Hefei,the economic center and capital of Anhui Province.2) Wuhu

  5. Continental tectonics and uranium province of South China

    International Nuclear Information System (INIS)

    The pre-Sinian metamorphic basement of South China consists of 4 blocks, namely the Jiangnan, the Wuyi, the Yunkai-South Sea and the Mintai which belong to the same lithospheric plate from late Proterozoic on. The plate is enriched in U and Th revealed by Pb-isotopic study, which plays an role of essential prerequisite for the formation of U province. The amalgamation of the 4 blocks and their final attachment to Yangtze craton were resulted from Proterozoic, Caledonian, Indonesia and Yangshanian orogenic events, driven by Moho-rheologic stratification so that uraniferous black rock sequences and U-hosting granites and volcanics in age from late Sinian to Jurassic were produced in the fore lands of corresponding major orogenic uplifts. The change of tectonic regime from compression-relaxed to lateral tension happened after significant crust's thickening and large-scale emplacement of granitic batholiths during late Triassic and early Jurassic though local compression occurred from middle Eocene to Oligocene. Most of U deposits were just formed in association with this para-cratonization process from late Jurassic to Eogene. South China GGT shows that there exist the thinning and the break-up of undercrustal lithosphere at the Datian and the Quanzhou and funnel-shaped seg at middle Hunan. The former two are considered to be the product of up-migration of hot mantle plume and the latter to be the place of down-migration of cold mantle plume

    Full Text Available Since reforms carried out in the late 1970s, China has experienced unprecedented rates of urban growth. Remote sensing data and surface observational data are used to investigate the urbanization process and related environmental consequences, focusing on extreme heat events and air pollution, in Zhejiang Province (ZJP, East China. Examination of satellite-measured nighttime light data indicates rapid urbanization in ZJP during the past decade, initially forming three urban clusters. With rapid urban sprawl, a significant Urban Heat Island (UHI effect has emerged. During extreme heat events in summer, the UHI effect significantly exacerbates nocturnal heat stress in highly urbanized areas. Taking a long-term view, urbanization also causes additional hot days and hot degree days in urban areas. Urbanization also imposes a heavy burden on local and regional air quality in ZJP. Degraded visibility and an increase in haze days are observed at most meteorological stations, especially in the three urban clusters. The results show that urbanization has led to serious environmental problems in ZJP, not only on the city scale, but also on the regional scale. Maintaining a balance between the continuing process of urbanization and environmental sustainability is a major issue facing the local government.

    By employing balanced panel data of listed companies of Anhui province during 2007 -2009, this paper measures the technical efficiency based on SFA. CEO plays an important role in decision - making, but the technical staffs play an important role in the business of technology development and innovation. Therefore, we investigate the influence of the annual pay of CEO and the number of technical staffs on technical efficiency. The empirical results show:the average firm efficiency is only 71. 5%, which means economic growth still relies on increasing inputs rather than on inner growth; the annual pay of CEO and technical efficiency are positively correlated; however, there are no significant relationship between the number of technical staffs and technical efficiency.%以2007~2009年43家安徽省上市公司为样本,运用随机前沿(SFA)方法测算各家公司的技术效率,同时考察总经理年度报酬以及技术人员数量对企业技术效率的影响.实证分析结果表明,安徽省上市公司的技术效率均值只有71.5%,说明经济增长仍然是靠增加要素投入而不是真正的内涵型增长;总经理报酬与企业技术效率呈现正相关关系;但技术人员数量与技术效率没有显著关系.

    在美国等西方国家,代际时间转移动机是公共转移项目和政策的关键决定因素。然而,在中国文化中,这一概念相对比较新颖。目前尚无子女的孩次、性别与中国农村老年人代际时间转移之间影响的研究。本文旨在从农村地区父母的角度,按子女的性别和孩次,探究时间转移的动机。本研究的数据为2009年从中国安徽省巢湖地区收集。研究结果显示从父母的视角分析,子女的孩次对代际时间转移动机有显著的影响,而子女性别的影响不显著。此外,本文讨论了对政府政策和未来研究的启示。%In the United States and other Western countries, the intergenerational transfer motivation is a key determinant of public transfer programs and policies. However, in Chinese culture, the concept is relatively new. Currently there is less research about rural birth order and gender influence on intergenerational time transfer in China. This article analyzed intergenerational time transfer motivation by the birth order and gender in perspective of rural parents. In this study, the data collected from Chaohu, Anhui Province, China in 2009. The results showed that from the perspective of parents, their children's birth order have a significant impact on intergenerational transfer motivation and children's gender had no significant effect. In addition, the article discusses the revelation of government policy and future research.

  7. Inventory of anthropogenic mercury emission Southwest China: I. Guizhou province

    International Nuclear Information System (INIS)

    The anthropogenic emissions of mercury to air is considered to contribute by 50-75 % of the total, and is thus responsible for elevated mercury concentration in the global atmosphere. These elevated atmospheric levels may be a serious threat to terrestrial and aquatic ecosystems due to wet or dry deposition. Hence, measures must be taken in controlling the anthropogenic emissions of mercury. A fundamental step of a global mercury control is realistic mapping of anthropogenic and natural emissions. Today, reasonably well documented mercury emission inventories of anthropogenic point sources exist in Europe and North America. The amount of anthropogenic emissions in other parts of the world is quite uncertain, as well as world-wide diffuse emissions (anthropogenic and natural). Guizhou is situated on a plateau with a mean altitude of about 1000 m. Its climate is a typical subtropical humid monsoon with an average annual temperature of 15 dec C and a precipitation of 1100-1400 mm. The province accounts for about 2.8% of the total population in China. (orig.)

    安徽南部晚震旦世蓝田组、皮园村组和早寒武世荷塘组主要由黑色页岩和硅质岩组成.分析结果表明,蓝田组和荷塘组的总有机碳(可达10%-18%)和总有机氮(可达2.0‰-2.6‰)的高含量,应归于富有机质埋藏所致,反映新元古代末次冰期后和早寒武世海洋浮游生物处于大发展时期.由于海洋植物的光合作用产生大量O2,并消耗大量CO2,导致大气中O2/CO2比率明显增加,为震旦纪晚期多细胞真核生物的辐射、后生动物的出现和‘寒武纪生物大爆发'提供了条件.蓝田组黑色页岩中部的有机碳与有机氮含量大体呈现正比例增加,并且分别达到17.74%和2.66‰的最高值,与该剖面发现的蓝田植物群相对应;荷塘组黑色页岩的有机碳和有机氮垂直分布曲线之间呈现相互背离,即有机氮含量与时增加,而有机碳含量与时减少,与扬子地台相应的地层层位产生的澄江动物群相对应,表明TON和TOC分布特征有可能与早期生物演化历程相关.%Organic carbon and organic nitrogen analyses in the Sinian-Early Cambrian succession of southern Anhui Province, China, show that the high contents of both total organic carbon (TOC: up to 10 %-18%) and total organic nitrogen (TON: up to 2.0‰-2.6‰) may reflect a great increase of organic matter burial and consequent rise in O2 concentration in the atmosphere and the upper ocean. It, in turn, may be attributed to a high primary productivity in the ocean, which resulted from a rise of major global temperature and enhanced tectonism after the Late Neoproterozoic glaciation. Warm climate and the rise in O2 concentration of the atmosphere may have triggered the radiation of multicellular eukaryotes in the Doushantuo time, development of the metazoan in the late Sinian and 'Cambrian Explosion'. In addition, the TON and TOC vertical distribution characteristics may be asso ciated with the early life evolution.

    Objectives: To evaluate the current status of magnetic resonance imagers (MRI) in Shanxi province and provide evidence for decision-making on the allocation of MRI in China. Methods Data on the allocation of MRI in Shanxi province from 1998 to 2002 were obtained using standardized questionnaires. Descriptive statistic was generated. Results Six major trends can be discerned from the study. 1) MRI is diffusing slower in Shanxi province than other countries including some developing countries such as Mexico. 2) MRI was firstly installed in tertiary level hospitals and then diffusion in lower level hospitals in Shanxi province. 3) Most of MR1 with superconducting magnet system have been installed in higher level hospitals. 4) The number of MRI in Shanxi province and Taiyuan municipality (the metropolis of Shanxi province) is more than that of standard promulgated by National Committee of Plan, and Ministry of Finance and MOH. 5) Although MRI diffusion in Shanxi province is developed rapidly, the number of MRI in Shanxi province is still less than the number of CT scanners. 6) Permanent magnet and superconducting magnet has emerged as the dominant MRI technology in Shanxi province. Conclusions 1) Diffusion of permanent magnet MRI should be supported sakes for a better function/price in the area of lower economic level such as Shanxi province. 2) Diffusion of MRI should be consistent with economic level. Economic level of districts should be considered when health policy related to MRI diffusion was made.

  4. The Income Gap among Rural Residents in Shaanxi Province,China

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    According to the analysis on the current status of the income gap among rural residents in Shaanxi Province,it is found out that the income of rural residents in Shaanxi Province of China is not only lower than the average income level of China,but also far lower than the income level of urban residents and the income level of rural residents in developed areas.The low income is mainly caused by the increasing income gap among income groups and the income gap among rural residents in different areas.Based on this,causations for the income gap among rural residents are analyzed from three aspects of the cultural difference,the regional economic difference,and the industrial structure difference.Countermeasures for narrowing the income gap and increasing the farmers’ income in Shaanxi Province are put forward,such as vigorously developing the rural economy and speeding up the transfer of rural surplus labor forces in China.

    Zhihui Zhang

    Full Text Available BACKGROUND: Recently, high proportions (15.6%-98.7% of intravenous drug users (IDUs in China were found to be positive for hepatitis C virus (HCV. Yunnan Province is located in southwestern China and borders one of the world's most important opium-producing regions, thus it is an important drug trafficking route to other regions of China. METHODOLOGY/PRINCIPAL FINDINGS: Here, we assessed 100 HCV-positive plasma samples from IDUs who were enrolled through the Kunming Center for Disease Control and Prevention in 2012. HCV C/E1 fragments were PCR-amplified and sequenced. We identified eight HCV subtypes (1a, 1b, 3a, 3b, 6a, 6n, 6u and 6v, of which genotype 6 was most predominant (frequency, 47% followed by genotypes 3 (41% and 1 (12%. HCV subtypes 6n (30% and 3b (29% were most common and were identified in 59% of the IDUs. We compared HCV genotypes among IDUs in Yunnan Province with those from other regions and found that the distribution patterns of HCV genotypes in Yunnan Province were similar to those in southern China, but different from those in eastern China. However, the distribution patterns of HCV subtypes varied among Yunnan Province and southern China, despite the shared similar genotypes. A comparison of the current data with those previously reported showed that the frequency of HCV genotype 6 increased from 25% to 47% within 5 years, especially subtypes 6a (5% to 15% and 6n (11.2% to 30%. In contrast, the frequencies of subtypes 3b and 1b decreased by almost 50% within 5 years. CONCLUSION/SIGNIFICANCE: Our results provided further information to support the assertion that drug trafficking routes influence HCV transmission patterns among IDUs in Yunnan Province. The frequency of HCV genotypes and subtypes changed rapidly among IDUs in Yunnan Province and subtypes 6a and 6n may have originated in Vietnam and Myanmar, respectively.

    After proposing the concept of "cohesive soil containing calcareous nodules", the distribution law, genesis, age and types of calcareous nodules of cohesive soil containing calcareous nodules in Huaibei Plain of Anhui Province are studied in detail. Based on field geology studies, tests, exploration and extensive reference to engineering geological exploration reports and professional literature data, the burial and distribution law of cohesive soil containing calcareous nodules are analyzed; and the plane distribution map and typical strata section maps of cohesive soil containing calcareous nodules are drawn. Cohesive soil containing calcareous nodules mainly distributes in the block between rivers, depression and the Yellow River Flood Plain in Huaibei Plain. The change law of the elevation of the roof of cohesive soil containing calcareous nodules and the ground elevation is basically identical. Calcareous concretions can generally be divided into three forms: embryonic calcareous concretions, mature calcareous concretions and calcareous hard pan. It is pointed out that there are embryonic calcareous, mature calcareous and calcareous hard pan from up to down on profile, the particle size and number of calcareous concretions increase gradually with depth and calcareous hard pan comes to being around the perennial groundwater level.

    Relationship between resource use and economic growth is the important field of resources and environmental economics studies. The paper attempts to integrate Material Flow Analysis (MFA) approach and the newly developed autoregressive distributed lag (ARDL)-bounds testing approach to examine the relationship between resource use and real GDP for Tongling City of Anhui Province,during the period of 1990~2008. The direct material input (DMI) ,one of sub-accounts of MFA,is also used as the proxy variable of resource use. The results of the bounds test indicate that a long-run cointegration relationship exists between the proxy of resource use and the explanatory variable:economic growth. The long-run parameters are estimated through a long-run static solution of the estimated ARDL model,and then the short-run dynamics are estimated by the error correction model. The study also indicates the existence of short-run and long-run causality running from resource use to economic growth. The findings imply that resource use is a stable forcing variable for economic growth in Tongling City. The estimation results are also of policy implication on economic development and resource conservation strategies for Tongling City.%资源利用与经济增长之间的关系是资源与环境经济学研究的重要领域.以安徽省铜陵市为例,尝试运用物质流分析方法以及最新发展的自回归分布滞后模型(ARDL)对铜陵市1990~2008年资源利用和实际GDP二者关系进行检验和分析.采用了物质流分析指标中直接物质投入来表征区域资源利用量.ARDL边界检验结果表明了资源利用和经济增长间存在稳定的长期均衡关系.进一步通过ARDL-ECM模型分析了区域经济增长对资源利用长期弹性系数和短期弹性系数,并揭示出资源利用对经济增长的短期和长期因果关系.研究结果表明当前资源投入在一定程度上拉动了铜陵经济增长.同时还对铜陵经济增长和

    对安徽查湾甜槠林林隙与林下土壤水分和养分进行了对比研究.结果表明:林隙土壤含水量垂直方向上随土层深度增加而递减;水平方向上,由林隙中心区往林下,土壤含水量呈递减趋势,说明林隙土壤的保水能力加强.林隙内外土壤pH值差异不大,林隙内pH值均略高于非林隙林分下相应各层;除表层外,土壤pH值在垂直方向上随土层深度的增加而增加;但土壤养分在垂直方向上分布规律差异较大,除了全钾质量分数由表层依次向下逐渐递增以外,其它各种养分均为逐渐递减,而且其它各养分在表层的含量明显高于其它土层的含量.林下土壤的有机质、全氮、碱解氮、速效磷、速效钾质量分数均高于林隙,而全磷、全钾质量分数是林隙高于林下.%An experiment was conducted to study the soil water content and nutrients in forest gaps and understory in Castanopsis eyrei stands in Zhawan Nature Reserve of Anhui Province. Results showed that soil water content decreased with soil depth, and it decreased from the center of forest gap to the understory, indicating that the soil in forest gap had better water holding capability. Soil pH in the forest gap was slightly higher than that in corresponding layer of understory, and soil pH increased with soil depth except for litter layer. The distribution of soil nutrients in vertical direction was different, that is, the content of total potassium increased with soil depth, while the contents of other nutrients decreased with soil depth, and the nutrient contents in the surface layer were obviously higher than those in other layers. The contents of soil organic matter, total nitrogen, alkaline hydrolytic nitrogen, available phosphorus and available potassium under the canopy were higher than those in the forest gap, while the contents of total phosphorus and total potassium were higher in the forest gap compared with the understory.

    Although Toxoplasma gondii infection in primary school children has been investigated in many countries, limited surveys have been available in primary school children in China. In the present study, we report the seroprevalence of T. gondii infection in primary school children in Shandong province, China. Sera from 6,000 primary school children were evaluated for T. gondii antibodies with ELISA. The overall seroprevalence of T. gondii infection was 16.0% (961/6,000), of which 14.5% (870/6,000) were positive for anti-T. gondii IgG antibodies, 3.4% (206/6,000) positive for IgM, and 1.9% (115/6,000) were positive for both IgG and IgM. The results of the present investigation indicated a high seroprevalence of T. gondii infection in primary school children in Shandong province, China. Therefore, effective measures should be taken to prevent and control T. gondii infection in primary school children in this province. To the best of our knowledge, this is the first report of T. gondii seroprevalence in primary school children in Shandong province, China. PMID:26323849

    2015-01-01

    This paper examines how left-behind children influence migration duration in China. We first present a simple illustrative model that incorporates economic and non-economic motives to migration duration. Using individual data from a survey carried out in Wuwei county (Anhui province) in 2008, we find that migrant parents of children in primary school tend to delay their return, a result we interpret as illustrating the need for migrant parents to accumulate money for their offspring’s educati...

  14. Regional allocation of CO2 emissions allowance over provinces in China by 2020

    International Nuclear Information System (INIS)

    The mitigation efforts of China are increasingly important for meeting global climate target since the rapid economic growth of China has led to an increasing share in the world's total CO2 emissions. This paper sets out to explore the approach for realizing China's national mitigation targets submitted to the UNFCCC as part of the Copenhagen Accord; that is, to reduce the intensity of CO2 emissions per unit of GDP by 40–45% by 2020, as well as reducing the energy intensity and increasing the share of non-fossil fuel consumption, through regional allocation of emission allowance over China's provinces. Since the realization of China's mitigation target essentially represents a total amount emission allowance allocation problem, an improved zero sum gains data envelopment analysis optimization model, which could deal with the constant total amount resources allocation, is proposed in this study. By utilizing this model and based on several scenarios of China's economic growth, CO2 emissions, and energy consumption, a new efficient emission allowance allocation scheme on provincial level for China by 2020 is proposed. The allocation results indicate that different provinces have to shoulder different mitigation burdens in terms of emission intensity reduction, energy intensity reduction, and share of non-fossil fuels increase. - Highlights: ► We explore the approach to realize national CO2 emissions reduction target of China by 2020. ► The CO2 emissions allowance is allocated over China's 30 administrative regions. ► Several scenarios of China's regional economy, emission, energy consumption are given. ► The zero sum gains data envelopment analysis model is applied in emission allowance allocation. ► An efficient emission allowance allocation scheme on provincial level is proposed

  16. The longevity of subcontinental lithospheric mantle beneath Jiangsu-Anhui Region ——The Os isotope model age of mantle-derived peridotite xenoliths

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The basalt-borne peridotite xenoliths from Jiangsu-Anhui provinces were analyzed for whole rock Os isotopic compositions in two laboratories of USTC, China and CRPG, France, respectively. The 187Os/188Os ratio of the sample set ranges from 0.119 to 0.129 (25 samples, USTC)and from 0.117 to 0.131 (17 samples, CRPG). The Os isotopic compositions of most samples are less than 0.129 and depleted relatively to the primitive mantle, showing a good correlation with the major element compositions. With the 187Os/188Os-Al2O3 alumichron, the samples yield a model age of 2.5 ± 0.1 Ga (data of USTC) and 1.9 ± 0.1 Ga (data of CRPG), late Archean to early Proterozoic, The two samples with the lowest 187Os/188Os ratio (0.119 and 0.117) have the TRD (Re depleted age) of 1.1 Ga (USTC) and 1.4 Ga (CRPG), mid-Proterozoic. The Os isotope model age shows that the peridotite xenoliths from Cenozoic alkali basalt in Jiangsu-Anhui provinces have an old formation age (early- to mid- Proterozoic). They are not newly produced mantle after the Phanerozoic replacement of the lithosphere mantle, but residual fractions of Proterozoic mantle.

    The black Piyuancun chert in Southern Anhui Province was deposited in terminal ediacaran to early cambrian transition period (about 550–532 Ma). The w(Ce)/w(Ce*) and w(LaN)/w(CeN) of the Piyuancun chert samples were 0.68–1.08 (avg. 0.85) and 0.56–1.52 (avg. 1.10), respectively, which indicates that the chert was deposited in the continental margin. Chert samples from the lower part and the upper part of the Lantian section have different rare earth elements (REE) patterns: REE concentrations for chert samples in the lower section are low relative to post-Archean Australian shale (PAAS), and their REE patterns are similar to that of the modern seawater, indicating that the influence of terrigenous detrital has been trivial. Although REE patterns for the chert samples in the upper section maintain some seawater characteristics, such as negative Ce anomaly and positive Y anomaly, they have flat REE patterns that are similar to PAAS, and their REE concentrations are close to that of PAAS, indicating that the influence of terrigenous detrital has been huge. Al2O3 content also displays the characteristics that the content are low in the lower section (0.03%–0.94%, avg. 0.41%) and are high in the upper section (0.74%–5.04%, avg. 2.98%). These geochemical characteristics show that the Piyuancun chert was probably deposited in the continental margin, and the water column became shallow (from basin margin to slope) for regression. The depth of the water column in which the Piyuancun chert deposited probably prompted the water column redox condition to change, and therefore affected the survival, evolution and distribution of early life.%皖南蓝田剖面皮园村组为一套埃迪卡拉纪−寒武纪过渡期(约550∼532 Ma)沉积的黑色硅岩.皮园村组硅岩样品的w(Ce)/w(Ce*)为0.68∼1.08(平均0.85), w(LaN)/w(CeN)为0.56∼1.52(平均1.10),指示它们可能形成于大陆边缘环境.剖面下部与剖面上部样品具有明显不同的稀土

    2016-01-01

    In the present study, we investigated the genetic characteristics of 25 Y-chromosomal and 15 autosomal short tandem repeat (STR) loci in 305 unrelated Han Chinese male individuals from Liaoning Province using AmpFISTR® Yfiler® Plus and IdentifilerTM PCR amplification kits. Population comparison was performed between Liaoning Han population and different ethnic groups to better understand the genetic background of the Liaoning Han population. For Y-STR loci, the overall haplotype diversity was 0.9997 and the discrimination capacity was 0.9607. Gene diversity values ranged from 0.4525 (DYS391) to 0.9617 (DYS385). Rst and two multi-dimensional scaling plots showed that minor differences were observed when the Liaoning Han population was compared to the Jilin Han Chinese, Beijing Han Chinese, Liaoning Manchu, Liaoning Mongolian, Liaoning Xibe, Shandong Han Chinese, Jiangsu Han Chinese, Anhui Han Chinese, Guizhou Han Chinese and Liaoning Hui populations; by contrast, major differences were observed when the Shanxi Han Chinese, Yunnan Bai, Jiangxi Han Chinese, Guangdong Han Chinese, Liaoning Korean, Hunan Tujia, Guangxi Zhuang, Gansu Tibetan, Xishuangbanna Dai, South Korean, Japanese and Hunan Miao populations. For autosomal STR loci, DP ranged from 0.9621 (D2S1338) to 0.8177 (TPOX), with PE distributing from 0.7521 (D18S51) to 0.2988 (TH01). A population comparison was performed and no statistically significant differences were detected at any STR loci between Liaoning Han, China Dong, and Shaanxi Han populations. The results showed that the 25 Y-STR and 15 autosomal STR loci in the Liaoning Han population were valuable for forensic applications and human genetics, and Liaoning Han was an independent endogenous ethnicity with a unique subpopulation structure.

  13. The development and practices of Strategic Environmental Assessment in Shandong Province, China

    International Nuclear Information System (INIS)

    Strategic Environmental Assessment (SEA), a newly-developed decision-making support tool, has been used in many developed and developing countries for predicting and evaluating potential environmental impact of policies, plans, and programs (PPPs), as well as for providing alternatives to avoid, mitigate, or compensate for these impacts. Unfortunately, due to the complexity and flexibility of SEA, to date there has been no consensus on a system which could be suitable for the contexts of different regions or countries. Different requirements and practices are observed in the different typical stages of SEA. Controversial areas include the appropriate indicators to apply in the early baseline setting stage, suitable methodologies for the impact assessment, and appropriate procedures for the SEA process. Given this, it is important to review and refine the SEA system specific to the context but informed by internationally agreed norms. As an illustration, this study reviews and proposes steps to refine the SEA system in Shandong Province, an economically powerful province of China, aiming to achieve sustainable development. Supported by the Environmental Impact Assessment Law of the People's Republic of China, Shandong Province employed SEA to reform the traditionally economy-oriented decision-making and incorporate consideration of environmental consequences into government deliberation on proposed PPPs. This paper illustrates the developmental process, procedures, and legal support for SEA in Shandong Province. By analyzing five SEA cases carried out by Shandong Province Environment Protection Bureau (SEPB) and Shandong University, problems in the SEA system were identified, and recommendations were made for improving the SEA system not only in Shandong Province but also other similar regions or countries.

    Mesozoic volcanic rocks in southeastern Jilin Province are an important component of the huge Mesozoic volcanic belt in the northeastern area. Study of the age of their formation is of great significance to recognize Mesozoic volcanic rule in northeastern China. Along with the research of rare Mesozoic biota and extensive Mesozoic mineralization in western Liaoning, a number of researchers have focused on Mesozoic volcanic events. The authors studied the ages of the Cretaceous volcanic rocks in southeastern Jilin Province using single Zircon U-Pb. The result shows that the Sankeyushu Formation volcanic rocks in the Tonghua area are 119.2 Ma in age, the Yingcheng Formation in the Jiutai area 113.4±3.1 Ma, the Jinjiatun Formation in Pinggang Town of Liaoyuan City and the Wufeng volcanic rocks in the Yanji area 103.2±4.7 Ma and 103.6±1 Ma, respectively. Combined with the data of recent publication on volcanic rocks ages; the Cretaceous volcanic events in southeastern Jilin Province can be tentatively subdivided into three eruption periods: 119 Ma, 113 Ma and 103 Ma. The result not only provides important chronology data for subdividing Mesozoic strata in southeastern Jilin Province, establishing Mesozoic volcanic event sequence, discussing geological tectonic background, and surveying the relation between noble metals to the Cretaceous volcanic rocks, but also otters important information of Mesozoic volcanism in northeastern China.

    2003-01-01

    Carbonatites in the Maoniuping REE deposit, Sichuan Province, which are spatially and temporally associated with rare earth mineralization, were emplaced at the time of Himalayan. The rocks are carbonatite-syenite complexes, with the mineral assemblages of calcite-aegirine-acmite- arfvedsonite-mica-orthoclase. The rocks are characterized by the enrichment in incompatible elements, such as Sr, Ba and REE, with C and O isotopic compositions of the "primary igneous carbonatites", relatively high initial 87Sr/86Sr ratios and low ??Nd values. All of these suggest that the rocks were derived from the metasomatic enriched mantle. It is demonstrated by geological and geochemical evidence that the mixing of the Himalayan subducting crustal materials with mantle source EM1 is probably the main factor responsible for the formation of carbonatites. The carbonatite-syenite complexes were generated from liquid immiscibility of CO2-rich alkalic silicate magma, which was derived from partial melting of the metasomatic mantle.

    Land use change is an important tactor tbr carbon emission. According to the assess- ment model and by using the Landsat TM data separately acquired in 1997 and 2007 on the eco- nomic circle of Hefei, the provincial capital of Anhui, the authors utilized data of land use types such as cultivated land, woodland, grassland and land for construction in 1997 and 2007 to calcu- late carbon emissions and the compensation standard based on price of fixation carbon dioxide. The results shows: 1 ) Carbon emissions greatly varied over different land use types, in which the land for construction and cultivated land were considered as two major carbon sources. Woodland and grassland were two major carbon sinks. Carbon emissions were found to increase by 14.4% per year over the entire economic circle of Hefiei from 1997 to 2007. Carbon emissions increased most quickly in the city, with an average annual growth rate of 32.3% during the ten years. With more impacts of human activities, carbon emission from land for construction was the highest, in- creased from 7.4587 million tons in 1997 to 17. 9409 million tons in 2007. However, carbon sink maintained generally stable during this period. 2 ) Two indexes describing carbon emissions, i. e. , carbon emission per unit area of land and carbon emission per unit area of construction land, were proposed. These two indexes could better reflect carbon emission intensity from 1997 to 2007 and the differences among the regions. Compared with carbon emission intensity in 1997, the two indexes increased by 1.18 and 1.41 times in 2007, respectively. Carbon emissions peak- ed in Hefei city, and showed a relatively higher level in Chaohu city and a low level in Lu' an cit- y, and the index of carbon emission per unit area of land and construction land indicated the same changing trend. 3 ) Carbon emission per unit area of land was markedly different in 15 counties or urban areas, and the three largest ones per unit area of

    2008-01-01

    Based on the examination of the global researches on oil and gas provinces and large gas fields and the analysis of the features,attributes and distribution of large gas provinces and gas fields,this paper puts forward three indicators of determining large oil and gas provinces:spatial indicator,reservoir-forming indicator and resource indicator.It classifies the gas accumulated areas and large gas provinces in China and analyzes the controlling factors on the distribution of large gas provinces and large gas fields:the lateral distribution is mainly controlled by high-energy sedimentary facies and constructive diagenetic facies,palaeo-highs and their periclinal zones,deep faults,etc,and the vertical distribution is mainly controlled by unconformities,series of evaporates and deep low-velocity highly-conductive beds,etc.It also reveals the main geological characteristics of large gas provinces and large gas fields in China.Large gas fields in four-type basins have their own characteristics and onland large gas fields are dominantly developed in foreland basins and craton basins;there are three types of gas sources,of which,coal is the main source with high gas generating intensity and varying origins;reservoir rocks of the large gas fields(provinces)are of various types and dominated generally by low-middle permeability and porosity pore-type reservoirs;structural traps and litho-stratigraphic traps coexist in Chinese large gas fields and form dense high abundance and large-area low and middle-abundance large gas fields;most of the large gas fields have late hydrocarbon-generation peaks and reservoir formation,and experienced the process of multiple-stage charging and late finalization; large gas provinces(fields)have good sealing and preservation conditions,and evaporates seals are largely developed in large and extra-large gas fields.This paper intends to shed light on the exploration and development of large gas fields(provinces)through analyzing their

    Full Text Available According to the framework of “Pressure-State-Response”, this study established an indicator system which can reflect comprehensive risk of environment and health for an area at large scale. This indicator system includes 17 specific indicators covering social and economic development, pollution emission intensity, air pollution exposure, population vulnerability, living standards, medical and public health, culture and education. A corresponding weight was given to each indicator through Analytical Hierarchy Process (AHP method. Comprehensive risk assessment of the environment and health of 58 counties was conducted in the Jiangsu province, China, and the assessment result was divided into four types according to risk level. Higher-risk counties are all located in the economically developed southern region of Jiangsu province and relatively high-risk counties are located along the Yangtze River and Xuzhou County and its surrounding areas. The spatial distribution of relatively low-risk counties is dispersive, and lower-risk counties mainly located in the middle region where the economy is somewhat weaker in the province. The assessment results provide reasonable and scientific basis for Jiangsu province Government in formulating environment and health policy. Moreover, it also provides a method reference for the comprehensive risk assessment of environment and health within a large area (provinces, regions and countries.

    Full Text Available OBJECTIVE: The aims of current study were to assess the level of tobacco knowledge, anti-tobacco messages and major information channels in Zhejiang. METHODS: Face-to-face interviews were conducted with 2112 adults in Zhejiang. Data on demographic information, smoking status, tobacco knowledge, anti-tobacco messages and major information channels was collected. RESULTS: The findings revealed that only 31.87% of the population were aware that smoking could cause all three diseases (stoke, heart disease, and lung cancer, 86.09% were aware that smoking causes lung cancer, 46.43% and 42.40% were aware that smoking causes stroke and heart attack, respectively. Residence and education level had significant effects on awareness, while the effects of smoking status, gender, age, and household monthly income were not significant. There were five major information channels as follows: television (67.52%, newspapers or magazines (40.79%, billboards (30.02%, public walls (24.72, and radio (23.79%. Respondents got the following anti-tobacco messages from mass media: "No smoking in public" (66.34%, "No smoking in front of other people" (35.18% and "Not offering cigarettes to one another" (22.82%. CONCLUSIONS: The tobacco knowledge among residents in Zhejiang province is relatively poor. Improved information channels and content of anti-tobacco messages are necessary to increase the public's tobacco knowledge, particularly among rural residents and people with less education.

    It is significant for the study on the sustainable development of regional agriculture to monitor and measure the trend of agricultural development with an effective method. The sustainable development of regional agriculture should accord with regional population, rural economic development, social progress, resource and environmental support. This paper establishes the evaluating indicators system of sustainable development of regional agriculture,evaluates the agricultural sustainable development in Shaanxi Province with a comprehensive multi-indicator method,analyzes the support of resource and environment for regional agriculture by the resource-development index and the environment-development index, and gets the conclusion that the indicators, such as education level, the income gap between urban and rural residents, the per capita area under cultivation and the consumption of pesticides and chemical fertilizers per hectare, are the main factors to restrict agricultural sustainability, and that the pressure of the development of subsystems of population, economy and society on the subsystems of resource and environment turns out to be stronger and stronger. Agricultural environment gets better, but resource becomes one of the important factors to restrict the development of regional agriculture. In a word, this paper highlights the potentials and limitations of sustainable agriculture of Shaanxi and helps identify the development direction in the future.

    The tailing soils were from 10 mining areas in Hunan Province. To predict the potential impact of tailings on nearby environments, the characteristics such as the pH value, loss on ignition, cation exchange capacity, and the concentration and speciation of heavy metals in the tailings were investigated. Based on these characteristics, the pollution index and danger index were calculated so as to evaluate the priorities of remediation. The results show that the concentrations of Pb, Cd, Cu and Zn exceed the tolerable levels of the phytotoxicity in the most tailings. The large proportion of heavy metals exists in the form of residual fraction in most tailings, followed by sulfides/organic and Fe/Mn oxide fractions, and a little in the exchangeable and carbonate fraction. The calculated pollution indices for the tailing samples range from 1.41 to 83.42, which indicates that all the tailings contain heavy metals at a level that causes toxicity to the ecosystem. The danger indices for the tailing samples range from 0.06 to 387.00. The highest value of the danger indices is that of Yongzhou sample, reaching 387.00; the lowest one is that of Xikuangshan sample, only 0.06. Considering the results of pollution index and danger index in combination, the priority of remediation is determined to be Yongzhou, Baoshan, Xiangtan and Lengshuijiang.

    Giardia duodenalis is a gastrointestinal protozoan that infects sheep. It is a well-known zoonotic pathogen and sheep have been implicated as a source of human infection. However, there have been few studies of its potential threat to public health in China. We used a multilocus analysis of the beta-giardin (bg), glutamate dehydrogenase (gdh), and triose phosphate isomerase (tpi) genes to examine the occurrence and genotype distribution of G. duodenalis in sheep in China. In total, 716 fresh faecal specimens, including 89 from pre-weaned lambs (3months old) from nine intensive sheep farms in Henan Province, China, were examined for Giardia cysts with microscopy. Of these specimens, 6.65% (47/716; 99% CI: 6.2%-6.92%) from five farms were positive for G. duodenalis. The infection rate was significantly higher in pre-weaned lambs than in post-weaned sheep (12.36% versus 5.74%, respectively; Pgiardiasis in human and sheep in Henan province, central China.

    伴随着我国新型城镇化进程加快,农村社会结构面临转型,农业劳动力的“离农”、“脱农”现象非常严重,未来“谁来种地”、“怎么种地”的问题已愈加突出。构建新型农业经营体系、深化农村改革已势在必然。立足于在推进新型城镇化过程中思考“三农”问题,阐述新型城镇化与新型农业经营体系的互动联系,以安徽省为例,分析新型农业经营体系发展存在的问题,在此基础上提出新型城镇化视角下安徽省构建新型农业经营体系的策略。%Along with the acceleration of new urbanization in our country, the rural social structure is in transition. As for the agricultural labor force, the phenomenon of“take off the farmers”or“out of agriculture” is very serious, and“who to farming” and“how to farming” are increasingly prominent in the future. Thus it is imperative to build a new type of agricultural management system and deepen the rural reform. Based on the implementation of “three rural” issue in the process of urbanization, this paper expounds the interaction between new urbanization and new agricultural management system. It takes Anhui province as an example, analyzing the problems existing in the construction of new agricultural management system. Based on this, this paper tries to put forward some countermeasures and suggestions to construct the new system of agricultural management in the new perspective of urbanization in Anhui province.

Methods Collecting measles epidemiology data before and after the MV SIA of 2009. Analyze the data with descriptive epidemiology. Results The MV SIAs in Anhui province were implemented in the October of 2009. The target population of the SIAs are the children aged from 8 months to 14 years. In 2010, both the number of reported measles cases and the measles incidence dropped to the lowestlevel since 2004, which were 439 cases and 0.72/100,000 respectively. The measles incidence of each age group among the children of 0-14 years old in 2010 dropped a lot comparing with that of 2009. Conclusions Carrying out high quality of SIAs at suitable time can control the epidemic of measles quickly, and decrease measles morbidity. Being a supplementary method for routine immunization, SIA is one of the important strategies to eliminate measles.

    Full Text Available Abstract Background Dengue fever has been a major public health concern in China since it re-emerged in Guangdong province in 1978. This study aimed to explore spatiotemporal characteristics of dengue fever cases for both indigenous and imported cases during recent years in Guangdong province, so as to identify high-risk areas of the province and thereby help plan resource allocation for dengue interventions. Methods Notifiable cases of dengue fever were collected from all 123 counties of Guangdong province from 2005 to 2010. Descriptive temporal and spatial analysis were conducted, including plotting of seasonal distribution of cases, and creating choropleth maps of cumulative incidence by county. The space-time scan statistic was used to determine space-time clusters of dengue fever cases at the county level, and a geographical information system was used to visualize the location of the clusters. Analysis were stratified by imported and indigenous origin. Results 1658 dengue fever cases were recorded in Guangdong province during the study period, including 94 imported cases and 1564 indigenous cases. Both imported and indigenous cases occurred more frequently in autumn. The areas affected by the indigenous and imported cases presented a geographically expanding trend over the study period. The results showed that the most likely cluster of imported cases (relative risk = 7.52, p  Conclusions This study demonstrated that the geographic range of imported and indigenous dengue fever cases has expanded over recent years, and cases were significantly clustered in two heavily urbanised areas of Guangdong province. This provides the foundation for further investigation of risk factors and interventions in these high-risk areas.

    2009-01-01

    The early evolution of angiosperms has been a focus of intensive research for more than a century. The Yixian Formation in western Liaoning yields one of the earliest angiosperm macrofloras. Despite multitudes of angiosperm fossils uncovered, Including Archaefructus and Sinocarpus, no bona fide normal flower has been dated to 125 Ma (mega-annum) or older. Here we report Callianthus dilae gen. at sp. nov. from the Yixian Formation (Early Cretaceous) in western Liaoning, China as the earliest normal flower known to date. The flower demonstrates a typical floral organization, including tepals, androecium, and gynoecium. The tepals are spatulata with parallel veins. The stamens have a slender filament, a globular anther, bristles at the anther apex, and in situ round-triangular pollen grains. The gynoecium is composed of two stylate carpels enclosed in a fleshy envelope, and develops into a "hip" when mature. Since the well-accepted history of angiosperms is not much longer than 125 Me, Callianthus together with Chaoyangia, Archaefructus and Sinocarpus from the Yixian Formation demonstrate a surprisingly high diversity of angiosperms, implying a history of angiosperms much longer than currently accepted.

  12. A 5-year longitudinal study of schistosomiasis transmission in Shian village, the Anning River Valley, Sichuan Province, the Peoples' Republic of China

    Full Text Available Abstract Background Schistosoma japonicum is a major public health concern in the Peoples' Republic of China (PRC, with over one million people infected and another 50 million living in areas at risk of infection. Based on ecological, environmental, population genetic and molecular factors, schistosomiasis transmission in PRC can be categorised into four discrete ecosystems or transmission modes. It is predicted that the Three Gorges Dam (TGD will impact upon the transmission of schistosomiasis in the PRC, with varying degree across the four transmission modes. We undertook longitudinal surveillance from 2002 to 2006 in sentinel villages both above and below the TGD across five provinces (Hunan, Jiangxi, Hubei, Anhui and Sichuan to determine whether there was any impact of the TGD on schistosomiasis transmission during its construction. Here we present the results from a schistosomiasis-endemic village located above the dam in Sichuan Province. Results Baseline results showed a human S. japonicum prevalence of 42.0% (95% CI: 36.6-47.5. At follow-up, results showed that the incidence of S. japonicum infection in the selected human cohort in Shian decreased by three quarters from 46% in 2003 to 11.3% in 2006. A significant (P S. japonicum infection in bovines declined from 11.8% in the first year to zero in the final year of follow-up. Conclusions The substantial decrease in human (75% and bovine (100% incidence observed in Shian village can probably be attributed to the annual human and bovine PZQ treatment of positives; as seen in drug (PZQ intervention studies in other parts of PRC. If an increase in schistosome transmission had occurred as a result of the TGD, it would be of negligible size compared to the treatment induced decline seen here. It appears therefore that the construction of the TGD had virtually no impact on schistosomiasis transmission in Shian village over the period of study. Furthermore, contrary to previous reports from

    Rabies is a major public health problem in some developing countries including China. One of the reasons is that there is a very large number of dogs, both domestic and stray, especially in Guangdong Province which has the third most rabies cases (after Guangxi and Hunan) among the 31 provinces, autonomous regions and municipalities in Mainland China, and at least 18.2% of the human rabies cases are caused by stray dogs. In this paper, based on the reported data and characteristics of the rabies infection in Guangdong Province, we propose a mathematical model for the dog-human transmission of rabies. We first determine the basic reproduction number R₀ and discuss the stability of the disease-free equilibrium and persistence of the disease. By carrying out sensitivity analysis of the basic reproduction number in terms of some parameters, we find that the domestic dog vaccination rate, the recruitment rate of domestic dogs, and the quantity of stray dogs play important roles in the transmission of rabies. This study suggests that rabies control and prevention strategies should include public education and awareness about rabies, increase of the domestic dog vaccination rate and reduction of the stray dog population.

    目的 了解安徽省社区卫生服务机构卫生技术人员的流动现况及特征.方法 采用按比例(25%)随机抽样方法,在安徽省12个市共抽取111个社区卫生服务机构,通过询问、查阅原始记录获取2007-2009年流入(出)卫生技术人员资料.结果 安徽省社区卫生服务机构2007-2009年卫生技术人员年流入率为6.8%~10.2%,年流出率为5.0%~7.5%,净流入率为-0.7%~3.9%.结论 卫生技术人员流动不仅影响到整个组织队伍的稳定,同时也增加了组织人力资源培训的成本和队伍建设周期.建议结合地方实际,制定社区卫生人力资源发展规划;关注社区卫生技术人员自身与组织的协调发展;不断完善社区卫生服务人员的工资福利、职称晋升等的制度设计.%Objective To Understand the status and characteristics of the technical personnel flow in community health service institutions in Anhui. Methods The randomly sampling on a proportion of 25% was used to choose 111 community health service institutions from 12 cities in Anhui. And the interview and consultation on the original records of the inflow ( outflow ) in 2007 - 2009 were applied to get the information. Results From 2007 to 2009 , the inflow percentage of health technical personnel of the community health service institutions in Anhui was 6. 8% - 10. 2% per year, while the outflow percentage was 5. 0% -7. 5 % per year, and the net inflow percentage was -0. 7% - 3. 9%. Conclusion It is the technical personnel flow that not only affects the stahility of the whole organization, but also increases the cost of training on human resources and extends the cycle of team construction. It is suggested that the development plan of community health human resources should be formulated according to local conditions ; the coordinate development of health technical staff with their organization should be focused; and the system programming on community health service staff

    The degradation of imazapyr in non-sterile and sterile soils from four sampling sites in Zhejiang, China was studied. The results showed that the half-lives of imazapyr in non-sterile soils were in the range of 30 to 45 d, while 81 to 133 d in sterile(by autoclaving) soils.It means the rate constants of imazapyr under non-sterile conditions were 2.3-4.4 times faster than that under sterile(by autoclaving) conditions, evidently indicating that the indigenous microorganisms in soil play an important role in the degradation of imazapyr. The different sterilization methods could result in different degradation rates of imazapyr. The heat of sterilization of soil largely decreased the degradation. However, the sterile treatment of soil by sodium azide had a different effect from that by autoclaving. Further more, the mechanism was also discussed. Biodegradation in four non-sterile soils accounted for 62% to 78% of imazapyr degradation. In contrast,less than 39% of imazapyr degradation was associated with chemical mechanisms. Therefore, the degradation mechanism was predominantly involved in biology including organisms and microorganisms in soil. Two imazapyr-degrading bacterial strains were isolated in enrichment culture technique and they were identified as Pseudomonas fluorescenes biotype Ⅱ (ZJX-5) and Bacillus cereus(ZJX-9),respectively. When added at a concentration of 50 μg/g in mineral salts medium(MSM), ZJX-5 and ZJX-9 could degrade 81 % and 87%imazapyr after 48 h of incubation. For the treatment of incorporation of ZJX-5 or ZJX-9 into soil, the degradation rate enhanced 3-4 fold faster than that for control samples, which showed an important value in quick decontamination of imazapyr in soil.

    There are many uncertainties in the estimation of forest carbon sequestration in China,especially in Liaoning Province where various forest inventory data have not been fully utilized.By using forest inventory data,we estimated forest vegetation carbon stock of Liaoning Province between 1993 and 2005.Results showed that forest biomass carbon stock increased from 68.91 Tg C in 1993 to 97.51 Tg C in 2005,whereas mean carbon density increased from 18.48 Mg.ha-1 C to 22.33 Mg·ha-1 C.The carbon storage of young- and middle-aged forests increased by 22.1 Tg C and 5.95 Tg C,but that of mature forests has decreased by 0.25 Tg C.The carbon stock and density of forests in Liaoning Province varied greatly in space:larger carbon storage and higher carbon density were primarily found in the east area.The spatial distribution of carbon density was determined by many factors,of which human activities played an important role.The forests in Liauning Province played a positive role as a sink of atmospheric carbon dioxide.The carbun fixation ability of forests in this area was primarily derived from forest plantation and the total forest carbon sequestration can be enhanced by expanding young- and middle-aged forests.

    In this study, we thoroughly analyzed spatial and temporal distributions of runoff and their relation with precipitation changes based on monthly runoff dataset at 25 hydrological stations and monthly precipitation at 127 stations in Guangdong Province, south China. Trends of the runoff and precipitation are detected using Mann-Kendall trend test technique. Correlations between runoff and precipitation are tested using Spearman's and Pearson's correlation coefficients. The results indicate that: (1) annual maximum monthly runoff is mainly in decreasing tendency and significant increasing annual minimum monthly runoff is observed in the northern and eastern Guangdong Province. In addition, annual mean runoff is observed to be increasing at the stations located in the West and North Rivers and the coastal region; (2) analysis of seasonal runoff variations indicates increasing runoff in spring, autumn and winter. Wherein, significant increase of runoff is found at 8 stations and only 3 stations are dominated by decreasing runoff in winter; (3) runoff changes of the Guangdong Province are mainly the results of precipitation changes. The Guangdong Province is wetter in winter, spring and autumn. Summer is coming to be drier as reflected by decreasing runoff in the season; (4) both precipitation change and water reservoirs also play important roles in the increasing of annual minimum monthly streamflow. Seasonal shifts of runoff variations may pose new challenges for the water resources management under the influences of climate changes and intensifying human activities.

    Full Text Available Yunnan province is the core region of the drought in the Southwest China, which makes the region become the hot spot in the meteorological research. However, among the various influencing factors of the drought in Yunnan province, the influence of the land use/cover change (LUCC on the drought has not been quantitatively analyzed. The LUCC in recent decades was first quantitatively analyzed in this study. Given the fact that severe drought in Yunnan province is mainly due to much-less-than-normal precipitation and much-warmer-than-normal surface temperature, this study focused on the future spatiotemporal heterogeneity of the temperature and precipitation, which have great impacts on the drought. Finally, the influencing factors of drought in Yunnan province were simulated with the Weather Research and Forecasting (WRF model, and the risk of drought was spatially analyzed with the meteorological drought composite index. The results indicate that the large-area forest plays a more important role in alleviating the risk of drought than other vegetation types do. Besides, the changes of the landscape structure resulting from the urban expansion play a significant role in intensifying the risk of drought.

    Characteristics and distribution patterns of clastic minerals (0.063~0.125 mm) in bottom sediments represent a significant indicator for the identification of the origin of sediment. One hundred and fourteen surface sediment samples, which were collected from the area near the Zhongsha Islands in the South China Sea, were analysed to identify the mineral suites and their distributions in the study area. The area can be divided into three mineral provinces: (Ⅰ) a province of biogenic minerals, which mainly originate from the Zhongsha Atoll; (Ⅱ) a province of volcanogenic minerals, which are mainly derived from local basaltic seamounts and small-scale volcanoes that are probably erupting, with some influences from the island-arc volcanic region around the South China Sea; and (Ⅲ) a mixed mineral province whose material source includes biogenic minerals, volcanogenic minerals and terrigenous minerals; the last province can be subdivided into a mixed mineral sub-province of the northeastern part of the study area, in which terrigenous minerals are mainly derived from China's Mainland and do not exceed 17°N, and a mixed mineral sub-province of the southeastern part of the study area, in which terrigenous minerals are derived from Kalimantan and Indochina Peninsula and might be further transported into the deep sea basin through submarine canyons.

    Identification and management the 'critical risk areas' where hotspot lead exposures are a potential risk to human health, become a major focus of public health efforts in China. But the knowledge of health risk assessment of lead pollution at regional and national scales is still limited in China. In this paper, under the guidance of 'sources-pathways-receptors' framework, regional human health risk assessment model for lead contamination was developed to calculate the population health risk in Yunnan province. And the cluster and AHP (analytic hierarchy process) analysis was taken to classify and calculate regional health risk and the decomposition of the regional health risk in the greatest health risk region, respectively. The results showed that Yunnan province can be divided into three areas. The highest health risk levels, located in northeastern Yunnan, including Kunming, Qujing, Zhaotong region. In those regions, lead is present at high levels in air, food, water and soil, and high population density which pose a high potential population risk to the public. The current study also reveals that most regional health risk was derived from the child receptors (age above 3 years) 4.3 times than the child receptors (age under 3 years), and ingestion of lead-contaminated rice was found to be the most significant contributor to the health risk (accounting for more than 49% health risk of total). This study can provide a framework for regional risk assessment in China and highlighted some indicators and uncertainties. PMID:25893826

    A new salamandroid salamander, Qinglongtriton gangouensis (gen. et sp. nov.), is named and described based on 46 fossil specimens of juveniles and adults collected from the Upper Jurassic (Oxfordian) Tiaojishan Formation cropping out in Hebei Province, China. The new salamander displays several ontogenetically and taxonomically significant features, most prominently the presence of a toothed palatine, toothed coronoid, and a unique pattern of the hyobranchium in adults. Comparative study of the new salamander with previously known fossil and extant salamandroids sheds new light on the early evolution of the Salamandroidea, the most species-diverse clade in the Urodela. Cladistic analysis places the new salamander as the sister taxon to Beiyanerpeton, and the two taxa together form the basalmost clade within the Salamandroidea. Along with recently reported Beiyanerpeton from the same geological formation in the neighboring Liaoning Province, the discovery of Qinglongtriton indicates that morphological disparity had been underway for the salamandroid clade by early Late Jurassic (Oxfordian) time.

    Compared with United States of America (USA), Brazil, Chile, Australia, limited attention has been paid to marine debris research in China and few studies have attempted to quantify the abundance and mass of marine debris. In this study, firstly the general status and sources of marine debris in China were assessed in the time period between 2007 and 2014, and secondly marine debris situation was evaluated in three China Sea Areas (the North China Sea, the East China Sea and the South China Sea) from 2009 to 2013, and finally marine debris conditions and sources were analyzed in beaches or seawaters around some coastal provinces of China during 2007-2013. Based on above analysis, the primary conclusions were as follows: (1) The mean number and weight densities of beached marine debris (BMD) and submerged marine debris (SMD) were 4.30, 0.13items/100m(2) and 133.80, 22.60g/100m(2) in China from 2007 to 2014, respectively. The average number density of the large size FMD (LOSFMD) was 0.0024items/100m(2) and that of the small and medium size FMD (SMSFMD) was 0.30items/100m(2), and the mean weight density of the SMSFMD was 1.40g/100m(2) from 2008 to 2014. The SMD and FMD densities were at the low level and the BMD density was at the high level in China. (2) The marine debris primarily was comprised of plastic, Styrofoam, wood, glass, rubber, fabric/fiber and metal, which included almost all major categories of marine debris. (3) Sources of BMD and FMD were as follows: the first source was coastal/recreational activities, followed by other disposal sources, navigation/fishing activities and the activities related smoking, and the least source being those associated with medical/sanitary activities, while the source of SMD remained unknown. (4) The mean number and weight densities of BMD were the biggest in the North China Sea, while those of FMD and SMD were the highest in the northern South China Sea. The results of this study were beneficial to the establishment of

    Heilongjiang province is the largest forest zone in China and the forest coverage rate is 46%. Forests of Heilongjiang province play an important role in the forest ecosystem of China. In this study we investi-gated the spatial distribution of forest carbon storage in Heilongjiang province using 3083 plots sampled in 2010. We attempted to fit two global models, ordinary least squares model (OLS) , linear mixed model (LMM), and a local model, geographically weighted regression model (GWR), to the relationship between forest carbon content and stand, environment, and climate factors. Five predictors significantly affected forest carbon storage and spatial distribution, viz. average diameter of stand (DBH), number of trees per hectare (TPH), elevation (Elev), slope (Slope) and the product of precipitation and temperature (Rain_Temp). The GWR model outperformed the two global models in both model fitting and prediction because it successfully reduced both spatial auto-correlation and heterogeneity in model residuals. More importantly, the GWR model provided localized model coefficients for each location in the study area, which allowed us to evaluate the influences of local stand conditions and topographic features on tree and stand growth, and forest carbon stock. It also helped us to better understand the impacts of silvi-cultural and management activities on the amount and changes of forest carbon storage across the province. The detailed information can be readily incorporated with the mapping ability of GIS software to provide excellent tools for assessing the distribution and dynamics of the for-est-carbon stock in the next few years.

    Full Text Available Abstract In 2007, herds of pigs in Jiangxi Province, China experienced outbreaks of a severe form of suspected porcine reproductive and respiratory syndrome (PRRS characterized by high fever, high morbidity and mortality in animals of different ages. 152 swine sera and 42 tissues (consisting of liver, lung, lymph node and kidney from five herds of pigs were collected. Pigs were diagnosed as infected with a highly pathogenic form of the PRRS virus (PRRSV based on ELISA and reverse transcriptase polymerase chain reaction (RT-PCR results. Serological surveys indicated that 67-100% of the examined pig herds in Jiangxi Province were seropositive. 42 tissue samples were used to detect classical swine fever virus, porcine circovirus type 2 and PRRSV. Results indicated that only PRRSV was detected in 42 samples. 12 PRRSV amplified products of five herds, which consisted of two or three samples randomly selected from each herd, were used for sequencing. Subsequent nucleotide sequencing showed that the NSP2 gene had 99–99.7% nucleotide and 99.2–100% derived amino acid sequence identities among 12 tissues with that of the PRRS-JXA1 strain, deletions of 29 amino acids corresponded to positions 534–562 of the NSP2 gene sequence. These results revealed that the diseased pigs were all caused by fatal PRRSV variant. Compared with the same period in 2006, the number of positive cases from Jiangxi Province remained unchanged. These findings demonstrated that the highly pathogenic Northern American type PRRSV was still spreading in Jiangxi Province, China in 2007.

    Hookworm infection as well as other intestinal nematodiases are endemic to Sichuan Province in China. In order to research the prevalence and intensity of these infections we visited two villages in Hejiang County (southern Sichuan Province) and Santai County (northwestern Sichuan Province) between July and October of 1997. Fecal examinations were performed on adult villagers over the age of 15 years (currently children under this age are dewormed annually with anthelmintic drugs). Among 310 residents of Lugao Village (Hejiang County), 87, 63 and 60% were infected with hookworm, Ascaris or Trichuris, respectively. The prevalence of hookworm determined to rise linearly with age (r = 0.97). High intensity infections with hookworm still occur in this region as 22% of the residents have over 3000 eggs per gram (PEG) of feces as determined by quantitative egg counts. The majority of these individuals harbored mixed infection with Necator americanus and Ancylostoma duodenale, although the former predominated when adult hookworms were collected from 30 village residents treated with pyrantel pamoate. In contrast, among the 334 Xinjian villagers examined (Santai County) the majority harbored predominantly light hookworm infections--66.1% of the residents has less than 400 EPG by quantitative fecal examination and only 3.7% exhibited greater than 3000 EPG. Again, N. americanus was the predominant hookworm seen after worm expulsion. We have round that despite economic development which is occurring in some parts of China, significant hookworm infections and clinical hookworm anemia still exist in areas of Sichuan Province. In Hejiang County we found that the intensity of hookworm infection has actually risen within the last 10 years. Hookworm is a medical problem among the elderly in Sichuan. PMID:10546842

    With the increased interest in remote sensing of wind information in recent years, it is important to determine the reliability and accuracy of new wind measurement technologies if they are to replace or supplement conventional tower-based measurements. In view of this, HydroChina Corporation and the United States National Renewable Energy Laboratory (NREL) conducted a comparative test near a wind farm in Hebei Province, China. We present the results of an analysis characterizing the measurement performance of a state-of-the-art Sound Detection and Ranging (sodar) device when compared to a traditional tower measurement program. NREL performed the initial analysis of a three-month period and sent the results to HydroChina. When another month of data became available, HydroChina and their consultant Beijing Millenium Engineering Software (MLN) repeated NREL's analysis on the complete data set, also adding sensitivity analysis for temperature, humidity, and wind speed (Section 6). This report presents the results of HydroChina's final analysis of the four-month period.

    Background China is the most severe endemic area of hemorrhagic fever with renal syndrome (HFRS) in the world with 30 000-50 000 cases reported annually, which accounts for more than 90% of total number of cases worldwide. The incidence rate of the syndrome in Shandong Province is one of the highest in China, which has ever reached 50 per 100 000 persons per year. However, the molecular characteristics of hantaviruses (HV) epidemic in Shandong Province remain unclear. Therefore it is useful to clarify nucleotide sequence and phylogenetic characteristics of HV isolated in Shandong Province in order to provide better advices to control and prevent HFRS.Methods RNAs were extracted from sera of clinically diagnosed patients and positive rodent lungs that were detected by indirect immunofluorescent assay (IFA). Partial M segments of HV were amplified from the RNAs with reverse transcription nested polymerase chain reactions (nested PCR) using hantavirus genotype specific primers. The nested PCR products were sequenced and compared with those from previously epidemic isolates in Shandong and with other representative HV sequences from GenBank. Phylogenetic tree analyses were performed based on the sequences of the M genes.Results Thirty-four HV isolates in Shandong showed 67.1%-100% nucleotide identities. The nucleotide homologies among 6 Hantaan viruses (HTNV) isolates in Shandong were 78.1%-98.7%, while the homologies among 28 Seoul virus (SEOV) isolates in Shandong were 93.7%-100%. There were at least 3 subtypes HTNV (H2, H5, H9) and 2 subtypes SEOV (S2, S3) in Shandong Province.Conclusions In Shandong Province, the homologies of HTNV were lower and there were no predominant subtypes,while the homologies of SEOV were higher and S3 was the predominant subtype. The homologies of SEOV from rodents were higher than those from patients. The distribution of subtypes in Shandong was similar to that of the adjoining provinces. Phylogenetic analyses of the sequences showed

    Full Text Available Abstract Background Toxoplasma gondii is an intracellular protozoan parasite infecting almost all warm-blooded animals, including birds, with a worldwide distribution. Surveys of T. gondii infection in wild birds have been reported extensively in the world, but little is known of T. gondii infection in peafowls worldwide. This study was performed to determine the seroprevalence of T. gondii infection in peafowls in Yunnan Province, southwestern China. Methods Sera from 277 peafowls, including 272 blue peafowls (Pavo cristatus and 5 green peafowls (Pavo muticus originated from two geographic areas in Yunnan Province were assayed for T. gondii antibodies using the modified agglutination test (MAT. Results Specific T. gondii antibodies were detected in 35 of 277 (12.64% peafowls (MAT titer ≥ 1:5. Seropositive birds were found in both species, 33 in 272 blue peafowls and 2 in 5 green peafowls. There was no significant difference in T. gondii seroprevalence between the adolescent birds (6.74% and the adult birds (6.67% (P > 0.05. The geographical origins of peafowls was found to be highly associated with T. gondii infection in the present study, a statistically significant difference in T. gondii seropositivity was observed between peafowls from Kunming (31.08% and those from Xishuangbanna Dai Autonomous Prefecture (5.91% (OR = 10.956, 95% CI = 1.632-73.545, P = 0.014. Statistical analyses showed that there were no significant interactions between ages and geographical origins of peafowls (P > 0.05. Conclusions The results of the present survey indicated that infection of peafowls with T. gondii is widespread in Yunnan Province, which has significant public health concerns and implications for prevention and control of toxoplamosis in this province. To our knowledge, this is the first seroprevalence report of T. gondii infection in China’s southwestern Yunnan Province.

  2. Impact of Manufacturing Transfer on SO2 Emissions in Jiangsu Province, China

    2016-05-01

    Full Text Available The impact of manufacturing transfer in Jiangsu province, China, on the spatial-temporal variations of SO2 emissions is investigated using estimated sector-specific SO2 emissions, and emissions in the different transfer-in and transfer-out regions were quantified during 2000–2011. Our results show that SO2 emissions had undergone three phases: an increase in the period of 2000–2005, a rapid decline in 2005–2008 and a slow decline in 2008–2011. Emissions from the south dominated the total emissions in the province. Cleaner production generally contributed to the reduced emissions, but rather, at the industrial scale. Pollution abatement was occasional and industrial structure was negligible in some years. The three phases also coincided with the three periods of the manufacturing transfer: transferred to the south from outside the province during 2000–2005, to the central from the south within the province during 2005–2008 and to the north from the south or partly from the inner central within the province during 2008–2011. With the manufacturing transfer, SO2 emission magnitudes and distributions were also changed. In the south, −12.36 and −5.62 Mt of SO2 emissions were transferred out during 2005–2008 and 2008–2011, respectively. Forty-three-point-four percent and 56.4% of the SO2 emissions in the south were transferred to the central and north during 2005–2008, respectively. The north region received 77.7% and 22.1% of SO2 emissions from the south and the central region during 2008–2011, respectively. The paper reveals that structure adjustments should be executed in a timely manner in the manufacturing transfer-in process so that the transfer-in regions can benefit from the economic boom without bearing a deteriorated environment.

  5. Determinants of agricultural water saving technology adoption: an empirical study of 10 provinces of China

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    In recent years,China has been faced by an increasingly severe water shortage due to the continua growth of demand on water resources.Although the Chinese government has been actively promoting the agricultural water-saving technology adoption,it is ill-informed of the adoption degree of the current agricultural water saving technologies as well as the function of the governmental policies.Therefore,this paper analyzes the aforesaid problems based on investigative data of 10 provinces in China.The results demonstrate that although there is a rapid increase of adopted agricultural water-saving technologies,the actual adoption area is rather limited.Moreover,the governmental policies and scarcity of water resources are the determinants of agricultural water-saving technology adoption.Ultimately,the paper proposes some policy suggestions.

    In a pilot study the presence and frequency of Clostridium (C.) perfringens was investigated among apparently healthy farm animals in the Shandong province of China. 748 faecal samples were collected from 9 pig-, 4 sheep-, 7 cattle- and 5 rabbit farms. C. perfringens was isolated from 124 samples (16.6%). The isolates were classified into major toxin types by using PCR analysis detecting the genes encoding these toxins. All isolates were identified as C perfringens toxin type A. There are also some reports from different regions in China linking C. perfringens toxin type A strains to gastrointestinal diseases. Therefore further investigations about the epidemiologic role of C perfringens toxin type A strains in the Shandong region are necessary. Currently, cases of enterotoxemia from this region are investigated for the presence of C perfringens. PMID:17970339

    A new basal neoceratopsian dinosaur, Helioceratops brachygnathus gen. et sp. nov., is described from the Quantou Formation (late Early Cretaceous or early Late Cretaceous) in the Liufangzi locality (Jilin province, China). Helioceratops differs from other basal neoceratopsiaus with its deep dentary ramus, its steeply-inclined ventral predentary facet, its heterogeneous dentary crowns, and by the denticles and secondary ridges asymmetrically distributed on either side of the primary ridge on its dentary teeth. Along with Auroraceratops and Yamaceratops, Helioceratops represents one of the most derived non-coronosaurian neoceratopsians. The palaeogeographical distribution of basal neoceratopsians appears limited to northern China and southern Mongolia in the current state of our knowledge. It is therefore probable that this region constituted the birthplace for more advanced, Late Cretaceous Coronosauria.

    International Nuclear Information System (INIS)

    This paper assesses the present and future market for household photovoltaic (PV) systems in rural Northwest China, especially from the PV commerce at Xining, Qinghai Province. This unsubsidised free market is now met by the emerging PV industry in China, which includes cell and module manufacturers, and PV system distributors and assemblers. For widespread deployment of such a renewable energy technology, the development of a local free market seems more successful than donor- or 'government subsidy'-driven programmes. Presently, there is a thriving infant PV industry in Northwest China, mostly centred in Xining. Xining-based PV sales companies have extensive networks for selling, marketing and servicing household PV systems for rural farmers and nomads. Small systems are now ordinary items on sale in local shops. Based on interviews and fieldwork observations with seven major PV sales companies in Xining, the household PV market is assessed from the present business operations of these companies. Detail of primary sources is given with the aim of archiving seminal progress in the history of photovoltaic power. The results suggest that although the household PV market will continue to grow, current government and international sponsored PV programmes can create both opportunities and barriers for the infant PV market an industry in China.

    Background Hepatitis A is a common acute hepatitis caused by hepatitis A virus (HAV). Annually, it affects 1.4 million people worldwide. Between 1991 and 1994, HAV infections were highly endemic in Zhejiang Province (China), with 78,720 reported HAV infections per year. Hepatitis A vaccine came on the market in 1995 and was implemented for voluntary immunization. Since 2008, hepatitis A vaccine has been integrated into the national childhood routine immunization program. Objective To understand the current epidemiological profile of hepatitis A in Zhejiang Province since hepatitis A vaccine has been available for nearly two decades. Methods This study used the 2005–2014 National Notifiable Diseases Reporting System data to evaluate the incidence rate of notified hepatitis A cases in Zhejiang Province. Results The overall trend of incidence rate of notified hepatitis A cases significantly decreased from 2005 to 2014 (Phepatitis A vaccine seemed to be effective in decreasing notified hepatitis A incidence rate in individuals aged ≤19 years. Those aged ≥20 years were observed to be the most susceptible population. The vast majority of hepatitis A cases were notified among Laborers. Therefore, we strongly suggest that future preventive and control measures should focus more on adults, particularly Laborers, in addition to the current childhood hepatitis A vaccination programme.

    Full Text Available Background: Several studies have investigated the prevalence and awareness of diabetes mellitus (DM in China, but little is known about the situation of DM in the northeastern rural areas. Our present study investigated the prevalence, awareness and associated characteristics of DM in rural areas of Jilin Province, aiming to suggest more efforts for the prevention and control of DM. Methods: A multistage stratified random cluster sampling design was used in this cross-sectional study which took place in 2012. Data were collected by face-to-face interviews and physical examinations. Rao-Scott Chi-square test, t test and multivariate logistic regression analysis were used. Results: The estimated prevalence of DM in rural areas of Jilin province was 7.2%. DM was positively associated with age, Body mass index (BMI, hypotension, dyslipidemia and was high in participants with a family history of diabetes and those who exercise frequently, but low for high education level and married participants. 69.0% participants with DM were aware of their diabetes status, 88.2% of whom received treatment and 34.4% of whom had received treatment controlled their DM status. Conclusions: We observed a high prevalence and low awareness status of DM among the rural residents in Jilin Province, but the rate of effective control in those who have received treatment was considerable. The low rate of disease surveillance should draw health authority’s attention.

    For the past 20 years the modern human origins debate has received a significant amount of attention in paleoanthropological research. Primarily supported by the evidence of earlier dates of anatomically modern human fossils and genetic studies, the "Out of Africa" hypothesis is based on the belief that the ancestor of all modern humans, including modern Chinese, came from Africa. The opposite hypothesis "Mutiregional evolution" proposes that continuous evolution occurred on a regional scale, for which human paleontology offers strong support. However, due to the paucity of hominid fossils in China between 100 and 50 ka, support to the latter hypothesis is currently weak. This is a report here of five human fossil teeth, and associated stone tools and mammal fossils from a newly discovered cave site, Huanglong Cave, located in Yunxi County,Hubei Province, China. Preliminary studies indicate:(1) the morphological features of the human fossils resemble those of late Pleistocene human fossils from China; (2) the stone tools display patterns of both the southern and northern Paleolithic cultures of China; (3) the mammal fossils represent the "Ailuropoda-Stegodon" faunal unit which lived in southern China throughout the Pleistocene. ESR and U-series dating on animal teeth and a stalagmite derived from the same layer as the human teeth indicate two possible ages: 103±1.6 ka and 44±12.5 ka. In addition to other evidence presented here, it is believed that hominid occupation of the cave was likely around 100 ka. If this age is further substantiated, Huanglong Cave will be the first late Pleistocene hominid fossil site in China where anatomically modern humans lived about 100 ka. The human fossils and other related materials from Huanglong Cave will provide important information for research on the origin of modern Chinese.

    Enterocytozoon bieneusi is one of the most important zoonotic pathogen that can infect almost all animals, including humans. However, little information is available regarding prevalence and genotypes of E. bieneusi in sika deer. In the present study, the prevalence of E. bieneusi infection in sika deer in Jilin province, Northeastern China was examined using PCR amplification of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene. 23 (7.06%) of 326 samples were tested E. bieneusi-positive, and the risk factor significantly associated with E. bieneusi prevalence was the age of sika deer. Sequence analysis of the ITS rRNA gene suggested that 8 genotypes of E. bieneusi were found in this study, with five known genotypes, namely J (n = 11), BEB6 (n = 4), EbpC (n = 1), CHN-DC1 (n = 1), KIN-1 (n = 1) and three novel genotypes, namely JLD-1 (n = 2), JLD-2 (n = 2) and JLD-3 (n = 1). Phylogenetic analysis indicated that genotypes CHN-DC-1, KIN-1, EbpC, JLD-2 and JLD-3 fell into group 1, while other three genotypes (genotypes J, BEB6 and JLD-1) were clustered into group 2 (so-called bovine-specific groups). These findings indicated the presence of zoonotic E. bieneusi in Jilin province, Northeastern China. Effective strategies should be performed to control E. bieneusi infection in sika deer, other animals and humans. PMID:27078663

  18. Isolation and characterization of a novel arenavirus harbored by Rodents and Shrews in Zhejiang province, China

    International Nuclear Information System (INIS)

    To determine the biodiversity of arenaviruses in China, we captured and screened rodents and shrews in Wenzhou city, Zhejiang province, a locality where hemorrhagic fever diseases are endemic in humans. Accordingly, arenaviruses were detected in 42 of 351 rodents from eight species, and in 12 of 272 Asian house shrews (Suncus murinus), by RT-PCR targeting the L segment. From these, a single arenavirus was successfully isolated in cell culture. The virion particles exhibited a typical arenavirus morphology under transmission electron microscopy. Comparison of the S and L segment sequences revealed high levels of nucleotide (>32.2% and >39.6%) and amino acid (>28.8% and >43.8%) sequence differences from known arenaviruses, suggesting that it represents a novel arenavirus, which we designated Wenzhou virus (WENV). Phylogenetic analysis revealed that all WENV strains harbored by both rodents and Asian house shrews formed a distinct lineage most closely related to Old World arenaviruses. - Highlights: • A novel arenavirus (Wenzhou virus) was identified in Zhejiang province, China. • The virus is highly circulating in five species of rats and one species of shrews • More efforts are needed to infer whether it is pathogenic to humans or not

    Full Text Available OBJECTIVE: To evaluate implementation of the National Essential Medicines Scheme (NEMS in rural China. METHODS: Two rural counties/districts in each of three provinces where NEMS had been implemented were surveyed. Information was collected from NEMS staff at the province, county/district, township and village levels; patients with chronic disease were also interviewed. Service provision, finances, prescriptions, inpatient records and the expenditures of patients with certain diagnoses were investigated in township hospitals and village clinics. The results were compared with the corresponding data recorded before NEMS was introduced. FINDINGS: Following the introduction of NEMS, drug procurement in each study location was systematized. Total drug costs declined. This, and improved prescribing, reduced the costs of outpatient and inpatient care and led, apparently, to increased uptake of health services. However, the prices of some drugs had increased and the availability of others had declined. The compensation of health-care providers for NEMS-related reductions in their incomes had been largely ineffective. As a result of the introduction of NEMS, health facilities relied more on public financing. Many health-care providers complained about higher workloads and lower incomes. CONCLUSION: Although it was well conceived, the introduction of NEMS into China's decentralized, fee-for-service system of health care has not been straightforward. It has highlighted the problems associated with attempts to modernize health care and health financing for patients' benefit. Sustainable mechanisms to compensate health-care providers for lost income are needed to ensure that NEMS is a success.

    Guizhou Province is one of the least developed areas with the largest number of counties in poverty and the widest coverage ofkarst landscape in China. The vulnerability of its karst eco-environment seriously threatens the survival of local residents and the development of local economy. Rapid population growth results in higher demand of various resources, which leads to more intensive development activities. For example, the blindfolded development on steep slopes has caused rock desertification of local rare soil in this karst area. It has induced a vicious circle in the poverty→population growth→ecosystem degradation and so on. About 3.13 ×l06 people belong to the absolute impoverished population in Guizhou Province and most of them are living in rock-desertification areas. The essential reasons for destitution are the atrocious eco-environment and the huge population stress. Degradation of mountain ecosystems in southwestern China has continued at unprecedented speed and scale in recent decades. It is necessary to control population growth strictly and prevent further expansion of rock-desertification in order to develop local economy and better living conditions for local people. The only way to ensure a sustainable, stable and harmonious development of human, nature and economy is to restore a good condition of eco-environment and resolve the conflicts between human and land use.

    Trichomonas vaginalis is a flagellated protozoan parasite that infects the human urogenital tract, causing the most common non-viral, sexually transmitted disease worldwide. In this study, genetic variants of T. vaginalis were identified in Henan Province, China. Fragments of the small subunit of nuclear ribosomal RNA (18S rRNA) were amplified from 32 T. vaginalis isolates obtained from seven regions of Henan Province. Overall, 18 haplotypes were determined from the 18S rRNA sequences. Each sampled population and the total population displayed high haplotype diversity (Hd), accompanied by very low nucleotide diversity (Pi). In these molecular genetic variants, 91.58% genetic variation was derived from intra-regions. Phylogenetic analysis revealed no correlation between phylogeny and geographic distribution. Demographic analysis supported population expansion of T. vaginalis isolates from central China. Our findings showing moderate-to-high genetic variations in the 32 isolates of T. vaginalis provide useful knowledge for monitoring changes in parasite populations for the development of future control strategies.

    Anthrax is a continuous threat in China, especially in rural regions. In July 2015, an anthrax outbreak occurred in Xifeng County, Liaoning Province. A total of 10 cutaneous anthrax cases were reported, with 210 people under medical observation. In this study, the general characteristics of human anthrax outbreak occurred in Liaoning Province were described, and all cases were caused by butchering and contacting sick animal. Meanwhile, the phylogenetic relationship between outbreak-related isolates/samples of the year 2015 and previous Bacillus anthracis strains was analyzed by means of canonical single nucleotide polymorphisms (canSNP), multiple-locus variable-number tandem repeat analysis (MLVA) with 15 markers and single-nucleotide repeats (SNR) analysis. There are two canSNP subgroups found in Liaoning, A.Br.001/002 and A.Br.Ames, and a total of six MLVA 15 genotypes and five SNR genotypes were observed. The strain collected from anthrax outbreak in Xifeng County in 2015 was classified as A.Br.001/002 subgroup and identified as MLVA15-29 genotype, with same SNR profile (CL10: 17, CL12: 15, CL33: 29, and CL35: 13). So we conclude that the same clone of B.anthracis caused the anthrax outbreak in Xifeng County in 2015, and this clone is different to previous isolates. Strengthening public health education in China is one of the most important measures to prevent and control anthrax. PMID:27299730

    It is well known that the mining industry produces a large amount of derelict land, and muses pollution of water loss and soil erosion as well as other environmental damage in China. As land is under pressure in China, it is now policy to restore or reclaim land despoiled by mining, the aim being to develop sustainable and healthy arable land ecosystems. This paper outlines the principles and approaches of ecological restoration, which have been adopted in Shanxi Province with reference to three typical surface mines. In the research, the principles of ecological engineering and ecological succession are considered as the critical theories of ecological restoration in mine degraded land. Meanwhile, the paper made a comparative research on main links of ecological rebuilding in three surface mines in Shanxi Province, which include new land construction, treatment of toxic substances, control of soil erosion, fertility management, irrigation, ecological planning and the establishment of legislation systems. As the research demonstrated, for successful restoration, new land construction is the fundamental framework, but it must be integrated with ecological engineering including ecological planning, the control of soil erosion and vegetation establishment and ecosystem creation in order to optimiee land productivity and soil fertility. In addition, the establishment of the legislation systems and organization of administration are also indispensable aspects of ecological rebuilding in mined land.

    The clinical and mycobacterial features of tuberculous meningitis (TBM) cases in China are not well described; especially in western provinces with poor tuberculosis control. We prospectively enrolled patients in whom TBM was considered in Shaanxi Province, northwestern China, over a 2-year period (September 2010 to December 2012). Cerebrospinal fluid specimens were cultured for Mycobacterium tuberculosis; with phenotypic and genotypic drug susceptibility testing (DST), as well as genotyping of all positive cultures. Among 350 patients included in the study, 27 (7.7%) had culture-confirmed TBM; 84 (24.0%) had probable and 239 (68.3%) had possible TBM. DST was performed on 25/27 (92.3%) culture positive specimens; 12/25 (48.0%) had "any resistance" detected and 3 (12.0%) were multi-drug resistant (MDR). Demographic and clinical features of drug resistant and drug susceptible TBM cases were similar. Beijing was the most common genotype (20/25; 80.0%) with 9/20 (45%) of the Beijing strains exhibiting drug resistance; including all 3 MDR strains. All (4/4) isoniazid resistant strains had mutations in the katG gene; 75% (3/4) of strains with phenotypic rifampicin resistance had mutations in the rpoB gene detected by Xpert MTB/RIF®. High rates of drug resistance were found among culture-confirmed TBM cases; most were Beijing strains. PMID:27143630

    Cryptosporidium spp., ubiquitous enteric parasitic protozoa of vertebrates, recently emerged as an important cause of economic loss and zoonosis. The present study aimed to determine the distribution and species of Cryptosporidium in post-weaned and adult pigs in Shaanxi province, northwestern China. A total of 1,337 fresh fecal samples of post-weaned and adult pigs were collected by sterile disposable gloves from 8 areas of Shaanxi province. The samples were examined by Sheather's sugar flotation technique and microscopy at × 400 magnification for Cryptosporidium infection, and the species in positive samples was further identified by PCR amplification of the small subunit (SSU) rRNA gene. A total of 44 fecal samples were successfully amplified by the nested PCR of the partial SSU rRNA, with overall prevalence of 3.3%. The average prevalence of Cryptosporidium infection in each pig farms ranged from 0 to 14.4%. Species identification by sequencing of SSU rRNA gene revealed that 42 (3.1%) samples were Cryptosporidium suis and 2 (0.15%) were Cryptosporidium scrofarum. C. suis had the highest prevalence (7.5%) in growers and the lowest in breeding pigs (0.97%). C. suis was the predominant species in pre-weaned and adult pigs, while C. scrofarum infected pigs older than 3 months only. A season-related difference of C. suis was observed in this study, with the highest prevalence in autumn (5.5%) and the lowest (1.7%) in winter. The present study provided basic information for control of Cryptosporidium infection in pigs and assessment of zoonotic transmission of pigs in Shaanxi province, China. PMID:25748718

  7. Links between environmental geochemistry and rate of birth defects: Shanxi Province, China

    International Nuclear Information System (INIS)

    The rate of birth defects in Shanxi Province is among the highest worldwide. In order to identify the impacts of geochemical and environmental factors on birth defect risk, samples of soil, water and food were collected from an area with an unusually high rate of birth defects (study area) and an area with a low rate of birth defects (control area) in Shanxi Province, China. Element contents were determined by ICP-OES, and the results were analyzed using a non-parametric test and stepwise regression. Differences in the level and distribution of 14 geochemical elements, namely arsenic (As), selenium (Se), molybdenum (Mo), zinc (Zn), strontium (Sr), iron (Fe), tin (Sn), magnesium (Mg), vanadium (V), calcium (Ca), copper (Cu), aluminum (Al), potassium (K) and sulfur (S) were thus compared between the study and control areas. The results reveal that the geochemical element contents in soil, water and food show a significant difference between the study area and control area, and suggest that the study area was characterized by higher S and lower Sr and Al contents. These findings, based on statistical analysis, may be useful in directing further epidemiological investigations identifying the leading causes of birth defects. - Research Highlights: → Environmental geochemistry has an significant impact on birth defects in the regions with an unusually high rate of birth defects. → An excess of S and deficiency of Sr and Al are the distinctive environmental features associated with the high rate of birth defects in the Shanxi Province of China. → Geochemical anomalies is a non-medical basis for effective prevention and cure of birth defects.

    China's cement industry, which produced 1,388 million metric tons (Mt) of cement in 2008, accounts for almost half of the world's total cement production. Nearly 40% of China's cement production is from relatively obsolete vertical shaft kiln (VSK) cement plants, with the remainder from more modern rotary kiln cement plants, including plants equipped with new suspension pre-heater and pre-calciner (NSP) kilns. Shandong Province is the largest cement-producing Province in China, producing 10% of China's total cement output in 2008. This report documents an analysis of the potential to improve the energy efficiency of NSP kiln cement plants in Shandong Province. Sixteen NSP kiln cement plants were surveyed regarding their cement production, energy consumption, and current adoption of 34 energy-efficient technologies and measures. Plant energy use was compared to both domestic (Chinese) and international best practice using the Benchmarking and Energy Saving Tool for Cement (BEST-Cement). This benchmarking exercise indicated an average technical potential primary energy savings of 12% would be possible if the surveyed plants operated at domestic best practice levels in terms of energy use per ton of cement produced. Average technical potential primary energy savings of 23% would be realized if the plants operated at international best practice levels. Energy conservation supply curves for both fuel and electricity savings were then constructed for the 16 surveyed plants. Using the bottom-up electricity conservation supply curve model, the cost-effective electricity efficiency potential for the studied cement plants in 2008 is estimated to be 373 gigawatt hours (GWh), which accounts for 16% of total electricity use in the 16 surveyed cement plants in 2008. Total technical electricity-saving potential is 915 GWh, which accounts for 40% of total electricity use in the studied plants in 2008. The fuel conservation supply curve model shows the total

    Full Text Available BACKGROUND: Maternal deaths occur mostly in developing countries and the majority of them are preventable. This study analyzes changes in maternal mortality and related causes in Henan Province, China, between 1996 and 2009, in an attempt to provide a reliable basis for introducing effective interventions to reduce the maternal mortality ratio (MMR, part of the fifth Millennium Development Goal. METHODS AND FINDINGS: This population-based maternal mortality survey in Henan Province was carried out from 1996 to 2009. Basic information was obtained from the health care network for women and children and the vital statistics system, from specially trained monitoring personnel in 25 selected monitoring sites and by household survey in each case of maternal death. This data was subsequently reported to the Henan Provincial Maternal and Child Healthcare Hospital. The total MMR in Henan Province declined by 78.4%, from 80.1 per 100 000 live births in 1996 to 17.3 per 100 000 live births in 2009. The decline was more pronounced in rural than in urban areas. The most common causes of maternal death during this period were obstetric hemorrhage (43.8%, pregnancy-induced hypertension (15.8%, amniotic fluid embolism (13.9% and heart disease (8.0%. The MMR was higher in rural areas with lower income, less education and poorer health care. CONCLUSION: There was a remarkable decrease in the MMR in Henan Province between 1996 and 2009 mainly in the rural areas and MMR due to direct obstetric causes such as obstetric hemorrhage. This study indicates that improving the health care network for women, training of obstetric staff at basic-level units, promoting maternal education, and increasing household income are important interventional strategies to reduce the MMR further.

    Data collection of soil organic carbon(SOC) of 154 soil series of Jiangsu, China from the second provincial soil survey and of recent changes in SOC from a number of field pilot experiments across the province were collected. Statistical analysis of SOC contents and soil properties related to organic carbon storage were performed. The provincial total topsoil SOC stock was estimated to be 0.1 Pg with an extended pool of 0.4 Pg taking soil depth of 1 m, being relatively small compared to its total land area of 101700 km2 . One quarter of this topsoil stock was found in the soils of the Taihu Lake region that occupied 1/6 of the provincial arable area. Paddy soils accounted for over 50% of this stock in terms of SOC distribution among the soil types in the province. Experimental data from experimental farms widely distributed in the province showed that SOC storage increased consistently over the last 20 years despite a previously reported decreasing tendency during the period between 1950-1970. The evidence indicated that agricultural management practices such as irrigation, straw return and rotation of upland crops with rice or wheat crops contributed significantly to the increase in SOC storage. The annual carbon sequestration rate in the soils was in the range of 0.3-3.5 tC/( hm2 · a), depending on cropping systems and other agricultural practices. Thus, the agricultural production in the province, despite the high input, could serve as one of the practical methods to mitigate the increasing air CO2.

    Objective To investigate the prevalence and influencing factors related to abuse and negligence against the elderly in the rural areas. Methods 975 elderly over 60 years from 41counties in Anhui province were included. All participants completed an anonymous questionnaire including items as: educational background, marital condition, income, child-discipline, rude action to parents, daily activities, physical functions, having chronic illness, abuse and negligence against the elderly, etc. Results In the last year, rates of common physical abuse, serious physical abuse,emotional abuse, financial exploitation, negligence, overall abuse and negligence against the elderly were 4.5%, 1.5%, 26.9%, 4.9%, 7.2%, 29.9% respectively. Among the 281 victims, 80.4% reported that they were suffered more than 3 times of abuse and neglect episodes, and 34.9% reported that they were suffered more than 2 forms of abuse and negligence. The primary sadism was carried out by the daughter-in-law or son-in-law (43.2%) of the elderly. Low activity on daily life and having chronic illness were the risk factors causing common physical abuse while better education was the protective factor to it, Low ability in managing daily activity of living was the risk factor causing serions physical abuse. Less active on daily life and having rude action to parents were the risk factors to emotional abuse, but being strict with their children was the protective factor to emotional abuse. Less active on daily life, often beating their children and having rude action to parents were the risk factors related to financial exploitation. Less active on daily life, having rude action to parents and having bad physical functions were the risk factors causing negligence. Less active on daily life and having rude manner to parents were the risk factors of overall elderly abuse and negligence, but being strict with their children was protective factor to the abuse and negligence against the elderly.

    The Wuxi gold deposit is located in Langqiao town, Jingxian county in South Anhui province, which is situated in the Jiangnan orogen, between the Middle and Lower Yangtze polymetallic metallogenic belt and South China metallogenic belt. The LA-ICP-MS dating results for zircons from the drill samples and outcrop rock in ore-bearing granite porphyry are consistent, 139.6±1.7 Ma(ZK7301), 137.3±1.6 Ma(ZK7001), 137.3±1.1 Ma (10WX-1), respectively. This intrusion is controlled by fault structure, and slightly contaminated by the early Archean crustal material. The developed cryptoexplosive breccia and mineralized breccia indicated the Wuxi orebody and granite porphyry were formed contemporaneously. The Wuxi granite porphyry is characterized by peraluminous, enriched in LILE (large ion lithophile elements), depleted in HFSE (high field strength elements) and heavy rare earth elements, significant differentiation between LREE and HREE, slight Eu negative anomaly. The apatite from the Wuxi granite porphyry has similar REE characteristics with those of the Yangtze series, indicating it was affected by mantle derived magmatic fluid activities; and the highδEu value of the apatite implies open tectonic environment and high oxygen fugacity during magma evolution. Zircon oxygen fugacity calculation indicates the granite porphyry formed in a high oxygen fugacity condition, thus it is conducive for precipitation and mineralization of Cu, Au and other ore-forming elements. While the formation of the Wuxi granite porphyry was closely related to the subduction and collision of the Paleo-pacific plate. The developed faults in the deposit provided channels for ore-forming fluid migration, which is conducive to the mineralization. Further prospecting and geochemical work are necessary for the area.%皖南乌溪金矿床位于安徽省泾县榔桥镇,介于长江中下游多金属成矿带与华南成矿带之间,属于江南造山带。本文对乌溪含矿花岗斑岩钻孔样

  15. Epidemiological surveillance of low pathogenic avian influenza virus (LPAIV from poultry in Guangxi Province, Southern China.

    Directory of Open Access Journals (Sweden)

    Yi Peng

    Full Text Available Low pathogenic avian influenza virus (LPAIV usually causes mild disease or asymptomatic infection in poultry. However, some LPAIV strains can be transmitted to humans and cause severe infection. Genetic rearrangement and recombination of even low pathogenic influenza may generate a novel virus with increased virulence, posing a substantial risk to public health. Southern China is regarded as the world "influenza epicenter", due to a rash of outbreaks of influenza in recent years. In this study, we conducted an epidemiological survey of LPAIV at different live bird markets (LBMs in Guangxi province, Southern China. From January 2009 to December 2011, we collected 3,121 cotton swab samples of larynx, trachea and cloaca from the poultry at LBMs in Guangxi. Virus isolation, hemagglutination inhibition (HI assay, and RT-PCR were used to detect and subtype LPAIV in the collected samples. Of the 3,121 samples, 336 samples (10.8% were LPAIV positive, including 54 (1.7% in chicken and 282 (9.1% in duck. The identified LPAIV were H3N1, H3N2, H6N1, H6N2, H6N5, H6N6, H6N8, and H9N2, which are combinations of seven HA subtypes (H1, H3, H4, H6, H9, H10 and H11 and five NA subtypes (N1, N2, N5, N6 and N8. The H3 and H9 subtypes are predominant in the identified LPAIVs. Among the 336 cases, 29 types of mixed infection of different HA subtypes were identified in 87 of the cases (25.9%. The mixed infections may provide opportunities for genetic recombination. Our results suggest that the LPAIV epidemiology in poultry in the Guangxi province in southern China is complicated and highlights the need for further epidemiological and genetic studies of LPAIV in this area.

    Full Text Available BACKGROUND: Sexually transmitted infections (STI have made a resurgence in many rapidly developing regions of southern China, but there is little understanding of the social changes that contribute to this spatial distribution of STI. This study examines county-level socio-demographic characteristics associated with syphilis and gonorrhea in Guangdong Province. METHODS/PRINCIPAL FINDINGS: This study uses linear regression and spatial lag regression to determine county-level (n = 97 socio-demographic characteristics associated with a greater burden of syphilis, gonorrhea, and a combined syphilis/gonorrhea index. Data were obtained from the 2005 China Population Census and published public health data. A range of socio-demographic variables including gross domestic product, the Gender Empowerment Measure, standard of living, education level, migrant population and employment are examined. Reported syphilis and gonorrhea cases are disproportionately clustered in the Pearl River Delta, the central region of Guangdong Province. A higher fraction of employed men among the adult population, higher fraction of divorced men among the adult population, and higher standard of living (based on water availability and people per room are significantly associated with higher STI cases across all three models. Gross domestic product and gender inequality measures are not significant predictors of reported STI in these models. CONCLUSIONS/SIGNIFICANCE: Although many ecological studies of STIs have found poverty to be associated with higher reported STI, this analysis found a greater number of reported syphilis cases in counties with a higher standard of living. Spatially targeted syphilis screening measures in regions with a higher standard of living may facilitate successful control efforts. This analysis also reinforces the importance of changing male sexual behaviors as part of a comprehensive response to syphilis control in China.

    Full Text Available Abstract Background Globally, China is the second place with high burden of tuberculosis (TB. To explore the characteristics of the pathogens of Mycobacterium tuberculosis (MTB circulating in this area is helpful for understanding and controlling the spread of the strains. Recent developments in molecular biology have allowed prompt identification and tracking specific strains of MTB spreading through the population. Methods Spacer-oligonucleotide typing (spoligotyping and mycobacterial interspersed repetitive units variable number tandem repeat (MIRU-VNTR were performed in combination to yield specific genetic profiles of 260 MTB strains isolated from 30 counties of Jiangsu province in China between June and July 2010. The spoligotyping results were in comparison to the world Spoligotyping Database of Institute Pasteur de Guadeloupe (SpolDB4. Drug susceptibility test (DST was performed on all strains by proportion method on Lowenstein-Jensen (LJ culture media. Results Based on the spoligotyping method, 246 strains displayed known patterns and 14 were absent in the database. Predominant spoligotypes belonged to the Beijing family (80.4%. By using the 24-loci VNTR typing scheme, 224 different patterns were identified, including 20 clusters and 204 unique patterns. The largest clade comprised 195 strains belonging to the Beijing family. The combination of spoligotyping and 24-loci MIRU-VNTR demonstrated maximal discriminatory power. Furthermore, we observed a significant association between Beijing family strains and drug-resistant phenotypes. The Beijing family strains presented increased risks for developing multi-drug resistant TB, with the OR (95% CI of 11.07(1.45-84.50. Conclusions The present study demonstrated that Beijing family isolates were the most prevalent strains circulating in Jiangsu province of China. The utility of spoligotyping in combination with 24-loci MIRU-VNTR might be a useful tool for epidemiological analysis of MTB

    Bioenergy, as one promising option to replace a fraction of conventional fossil fuels and lower net greenhouse gas emissions, has gained many countries', in particular developing ones' attention. Their focus is mainly on the design of efficient bioenergy utilization pathways which adapt to both local geographic features and economic conditions. The establishment of a biomass production sector would be the first and pivotal component in the whole industrial chain. Several existing studies have estimated the global biomass for energy potential but arrived at very different results. One reason for the large uncertainty of biomass potential may be ascribed to the diverse nature of biomass leading to different estimates in different circumstances. Therefore, specific research at the local level is essential. Following this thought, our research conducted in the Jiangsu province, a representative region in China, will explore the spatial distribution of biomass production. The employed methodology can also be applied to other locations both in China and similar developing countries if model parameters are adequately adjusted. In this study, we analyze the local situation in the Jiangsu province focusing on the selection of new energy crops, since the cultivation of dedicated crop for energy use is still in experimental phase. We also examine the land use conflict which is especially relevant to China with more than 1.3 billion people and a severe burden on food supply. We develop an agent-based model to find the optimal spatial distribution of biomass (SDA-SDB) in Jiangsu province. Compromising data accessibility and heterogeneity of environmental factors across the province, we resolve our model at county level and consider the aggregated farming community in one county as a single agent. The aim of SDA-SDB is to simulate farmers' decision process of allocating land to either food or energy crops facing limited resources and political targets for bioenergy development

    Two cultured marine fish, the Japanese seabass (Lateolabrax japonicus) and red seabream (Pagrus major) were collected from eight fish cage sites along the coast of Fujian province in China. The concentrations of Ag, As, Cd, Co, Cu, Fe, Mn, Se, and Zn in their muscle, stomach and liver tissue were quantified. The risk of these trace elements to humans through fish consumption was then assessed. The highest concentrations of As, Cd, Se and Zn in fish feed from fish cages were found in Dongshan Station. Moreover, the As levels in the muscles of both species at all sites were generally higher than China's national standard (>1.0 mug/g). Trace element concentrations in two marine fish followed the order of livers > stomachs > muscles. Although the As levels in two marine caged fish exceeded the permissible standards, the estimated daily intake of As did not exceed the reference dose guideline established by US EPA. For other trace elements examined in this study, their concentrations did not exceed the permissible concentrations of the international standards. - As levels in two marine caged fish from China exceeded the permissible standards, whereas the levels of others trace elements did not exceed the permissible concentrations.

    Full Text Available Abstract Background This study describes the patterns and socioeconomic influences of tobacco use among adults in tobacco-cultivating regions of rural southwest China. Methods A cross-sectional survey was conducted in 8681 adults aged ≥18 years in rural areas of Yunnan Province, China from 2010 to 2011. A standardized questionnaire was administered to obtain data about participants’ demographic characteristics, individual socioeconomic status, ethnicity, self-reported smoking habits, and exposure to secondhand smoke (SHS. The socioeconomic predictors of current smoking, nicotine addiction, and SHS exposure were analyzed using multivariate logistic regression. Results The prevalence rates of tobacco use were much higher in men compared with women (current smoking 68.5% vs. 1.3%; and nicotine dependence 85.2% vs. 72.7%. However, the rate of SHS exposure was higher in women compared with men (76.6% vs. 70.5%. Tobacco farmers had higher prevalence rates of current smoking, nicotine dependence, and SHS exposure compared with participants not engaged in tobacco farming (P Conclusions This study suggests that tobacco control efforts in rural southwest China must be tailored to address tobacco-cultivating status and socioeconomic factors.

    Yunxia Liu

    Full Text Available BACKGROUND: Hand, foot, and mouth disease (HFMD has caused major public health concerns worldwide, and has become one of the leading causes of children death. China is the most serious epidemic area with a total of 3,419,149 reported cases just from 2008 to 2010, and its different geographic areas might have different spatial epidemiology characteristics at different spatial-temporal scale levels. We conducted spatial and spatial-temporal epidemiology analysis to HFMD at county level in Shandong Province, China. METHODS: Based on the China National Disease Surveillance Reporting and Management System, the spatial-temporal database of HFMD from 2007 to 2011 was built. The global autocorrelation statistic (Moran's I was first used to detect the spatial autocorrelation of HFMD cases in each year. Purely Spatial scan statistics combined with Space-time scan statistic were used to detect epidemic clusters. RESULTS: The annual average incidence rate was 93.70 per 100,000 in Shandong Province. Most HFMD cases (93.94% were aged within 0-5 years old with an average male-to-female sex ratio 1.71, and the incidence seasonal peak was between April and July. The dominant pathogen was EV71 (47.35%, and CoxA16 (26.59%. HFMD had positive spatial autocorrelation at medium spatial scale level (county level with higher Moran's I from 0.31 to 0.62 (P<0.001. Seven spatial-temporal clusters were detected from 2007 to 2011 in the landscape of the whole Shandong, with EV71 or CoxA16 as the dominant pathogen for most hotspots areas. CONCLUSIONS: The spatial-temporal clusters of HFMD wandered around the whole Shandong Province during 2007 to 2011, with EV71 or CoxA16 as the dominant pathogen. These findings suggested that a real-time spatial-temporal surveillance system should be established for identifying high incidence region and conducting prevention to HFMD timely.

    Objective To assess the prevalence of depressive symptoms,trends on its longitudinal development and related influencing factors among primary and middle school students in Changfeng county of Anhui province. Methods Through cluster sampling methods,all students from 3 to 9 grades in 5 primary schools and 3 middle schools in Changfeng county of Anhui province were investigated through questionnaire as subjects of baseline survey in December 2009. Subjects of this longitudinal study were students in grades 3,4 and 7 at the time of the baseline survey and were contacted once a year for two years. At last,a total of 816 students participated in all the three surveys. A structured questionnaire including Children’s Depression Inventory,socio-demographic characteristics and some potential influential factors was employed for this study. A Generalized Estimating Equation (GEE) was used to evaluate the related influencing factors of children’s depressive symptoms in the longitudinal study. Results Prevalence rates of depressive symptoms were 11.3%,10.4% and 8.5%,respectively,at the baseline,1-year and 2-year follow-up studies, among primary and middle school students. Scores on depressive symptoms of total subjects and children who had always been left at home in the follow-up process showed significant differences at the three surveys (F=13.423,P<0.001;F=5.761,P=0.003). 25 percent of the 92 students who showed depressive symptoms at the baseline survey remained those depressive symptoms at the 1-year follow-up study and 87 percent of the 23 students who had depressive symptoms at the baseline and 1-year follow-up surveys still showing depressive symptoms at the 2-year follow-up study. Results from the GEE program indicated that grade 3 students,having syblings,family with dysfunction or at low level of self-esteem etc.,were prone to development while sex and parents’ educational level were not correlated with depressive symptoms.

  3. What is driving CO2 emissions in a typical manufacturing center of South China? The case of Jiangsu Province

    International Nuclear Information System (INIS)

    Investigating CO2 emissions of China's manufacturing centers contributes to local and global CO2 mitigation targets. This study considers Jiangsu Province as a representation of manufacturing centers in South China. Effects of material efficiency improvements, technology development, consumption structure changes and consumption volume growth in Jiangsu Province on its CO2 emissions during 1997-2007 are investigated using structural decomposition analysis based on environmental input-output table. In order to reduce CO2 emissions, Jiangsu Province should not only rely on material efficiency improvements and technology development, but also rely on consumption structure changes. For consumption structure changes in detail, Jiangsu Province should not only focus on fixed capital formation and urban residential consumption, but also focus on international and intranational imports and exports. For the implementation of material efficiency improvements and technology development, Jiangsu Province should focus on technology innovation and international technology transfer. For the implementation of consumption structure changes, Jiangsu Province should mainly focus on identified sectors for each separate final demand category: five sectors for urban residential consumption, three sectors for fixed capital formation, four sectors for international exports, five sectors for intranational exports, three sectors for international imports and four sectors for intranational imports. - Highlights: → Effects of four factors on Jiangsu Province's CO2 emission changes are analyzed. → Key factors are identified for Jiangsu Province to achieve CO2 mitigation targets. → Key areas for consumption structure changes are analyzed. → Technology innovation and technology transfer should be concerned. → Identified sectors for each final demand category should be concerned.

    Seismic refraction, profiles in Yunnan Province, southwestern China, define the crustal structure in an area of active tectonics on the southern end of the Himalaya-Burma arc. The crustal thickness ranges from 38 to 46 kilometers, and the relatively low mean crustal velocity indicates a crustal composition compatible with normal continental crust and consisting mainly of meta-sedimentary and silicic intrusive rocks, with little mafic or ultramafic component. This composition suggests a crustal evolution involving sedimentary processes on the flank of the Yangtze platform rather than the accretion of oceanic island arcs, as has been proposed. An anomalously low upper-mantle velocity observed on one profile but not on another at right angles to it may indicate active tectonic processes in the mantle or seismic anisotropy. PMID:17792016

    Noroviruses are a common cause of acute gastroenteritis around the world; however, reports of outbreaks caused by GII.17 norovirus are rare. An outbreak caused by GII.17 norovirus in a senior high school in Wuxi, Jiangsu Province, China is reported here. An epidemiological investigation, pathogen detection, and case-control study were performed. Epidemiological data combined with the epidemic curve indicated that this outbreak was a point source type initially, followed by secondary transmission. The first case was identified as most likely the source of the outbreak. Risk analysis showed exposure to patients and sharing a communal water cooler to be associated with the spread of infection. Sequence analysis of GII-positive samples confirmed that the norovirus GII.17 variant was the etiological agent of this outbreak. PMID:27224012

    The Maochang bauxite in Guizhou Province is one of the important aluminum ore deposits in southwestern China. Ferruginous spherules, measuring about a few microns across, were found in the transitional layer of the deposit. The EDS and XRD results show that the microspherules are composed mostly of iron (hydr)oxide minerals (goethite) with only weak presence of aluminum and silicon.Occasionally, some pyrite micrograins with dissolved surface are found associated with goethite within the spherules. It is thus suggested that microspherules are linked to pyrite oxidization. It is also thought that microbial activities contribute not only to pyrite oxidization, but also to ball-like assemblage of the iron (hydr)oxides. The mechanism of the formation of ferruginous microspherules is also believed to be important in studying geomicrobiology of bauxite.

    The quantitative assessment of geothermal water resources is important to the exploitation and utilization of geothermal resources. In the geothermal water systems the density of groundwater changes with the temperature, therefore the variations in hydraulic heads and temperatures are very complicated. A three-dimensional density-dependent model coupling the groundwater flow and heat transport is established and used to simulate the geothermal water flow in the karst aquifers in eastern Weibei,Shaanxi Province, China. The multilayered karst aquifer system in the study area is cut by some major faults which control the regional groundwater flow. In order to calibrate and simulate the effect of the major faults, each fault is discretized as a belt of elements with special hydrological parameters in the numerical model. The groundwater dating data are used to be integrated with the groundwater flow pattern and calibrate the model. Simulation results show that the calculated hydraulic heads and temperature fit with the observed data well.

    The very high prevalence of dental and skeletal fluorosis in relation to the fluorine content of local coal and clay was investigated in two rural regions with low water fluoride (Hualuo Village and Majianzhuang Village) of Guizhou Province, China. The fluorine content of coal in the two regions is considerably lower than the total fluorine content of the commonly used coal-clay (a mixture of coal and clay). The fluorine released from combustion of the coal itself accounts for less than 15% of the total fluorine emissions during the combustion of coal-clay, thereby indicating that the fluorine source that contaminates the food and air is mainly from the clay rather than the coal.

    International Nuclear Information System (INIS)

    A newly developed pedodiversity methodology was used in analyzing the distribution character of the soils in Henan province of central China. The rare soil types and representative soil types were defined after three soil parameters (soil patch numbers, total area and spatial distribution diversity in 2km×2km grid scale) were calculated respectively. Results show that there are positive correlations between soil patch numbers, total area and spatial distribution diversity, the regression equations between spatial distribution diversity and total area is y=0.086ln(x)-0.021, R2=0.992 and y=0.106ln(x)+0.161, R2=0.921 between spatial distribution diversity and patch numbers. The value constituent pattern of soil spatial distribution diversity fits the normal distribution. More attention needs to be paid to protect the endangered rare soil types. The soil type quantity per km2 is always different under different local conditions

    The genome of JEV strain SC201301, which was isolated from an aborted fetal piglet in 2013 in Sichuan province in China, was completely sequenced and phylogenetically analyzed. Sequence alignments showed that the SC201301 strain shared 97-100% sequence identity with other genotype III strains but showed less similarity to genotype I representative JEVs. Phylogenetic analysis indicated that the SC201301 strain belonged to genotype III and was most closely related to representative strains such as SA14-14-2, HW and SH0601. Our findings suggest that JEV genotype III is still prevalent in swine herds in Sichuan province in China, and thus, there is an urgent need to monitor the infection status of JEV among swine herds in China.

    2016-03-01

    Air pollution, causing significantly adverse health impacts and severe environmental problems, has raised great concerns in China in the past few decades. Guangdong Province faces major challenges to address the regional air pollution problem due to the lack of an emissions inventory. To fill this gap, an emissions inventory of primary fine particles (PM2.5) is compiled for the year 2012, and the key precursors (sulfur dioxide, nitrogen oxides) are identified. Furthermore, policy packages are simulated during the period of 2012-2030 to investigate the potential mitigation effect. The results show that in 2012, SO2, NO x , and PM2.5 emissions in Guangdong Province were as high as (951.7, 1363.6, and 294.9) kt, respectively. Industrial production processes are the largest source of SO2 and PM2.5 emissions, and transport is the top contributor of NO x emissions. Both the baseline scenario and policy scenario are constructed based on projected energy growth and policy designs. Under the baseline scenario, SO2, NO x , and PM2.5 emissions will almost double in 2030 without proper emissions control policies. The suggested policies are categorized into end-of-pipe control in power plants (ECP), end-of-pipe control in industrial processes (ECI), fuel improvement (FI), energy efficiency improvement (EEI), substitution-pattern development (SPD), and energy saving options (ESO). With the implementation of all these policies, SO2, NO x , and PM2.5 emissions are projected to drop to (303.1, 585.4, and 102.4) kt, respectively, in 2030. This inventory and simulated results will provide deeper insights for policy makers to understand the present situation and the evolution of key emissions in Guangdong Province.

    The Loess Plateau in northern Shaanxi Province of China covers Yulin, Yan'an, and Tongchuan cities mainly. The kind of physiognomy is complicated and various, including the transitional region of the sand and wind, the hilly-gully fragile region, the pimple mound region from North to South. Large-scale land reclamation projects that are severely affecting these ecosystems have been implemented. In this paper, we reported an investigation to the changes in land use and ecosystem services on the Loess Plateau in northern Shaanxi Province from 1978 to 2000. We used three LANDSAT TM and/or ETM data sets to estimate the changes in the size of five land-cover/land-use categories, and we also used previously published value coefficients to estimate the changes in the value of ecosystem services delivered by each land category. Finally, we ranked the contribution of various ecosystem functions to the overall value of the ecosystem services, we have estimated that the annual value of the ecosystem services is 56.95 billon RMB yuan in the Loess Plateau in northern Shaanxi Province in 2000. In the region, from 1978 to 2000, the economic value of the fixing carbon was higher,the economic value of water conservation was the lowest, but the economic value of the NPP, fixing carbon, and supplying oxygen accounted for above ninety percent of the total value, obviously the vegetation created the biggest ecosystem service value. We can conclude that future land-use policy formulation should give precedence to the conservation of these ecosystems over uncontrolled reclamation, and that further land reclamation should be based on rigorous environmental impact analyses.

    Heavy metal concentrations in agricultural soils of Zhejiang Province were monitored to indicate the status of heavy metal contamination and assess environmental quality of agricultural soils. A total of 908 soil samples were collected from 38 counties in Zhejiang Province and eight heavy metal (Cd, Cr, Pb, Hg, Cu, Zn, Ni and As) concentrations had been evaluated in agricultural soil. It was found 775 samples were unpolluted and 133 samples were slightly polluted and more respectively, that is about 14.65% agricultural soil samples had the heavy metal concentration above the threshold level in this province by means of Nemerow's synthetical pollution index method according to the second grade of Standards for Soil Environmental Quality of China (GB15618-1995). Contamination of Cd was the highest, followed by Pb, As and Hg were lower correspondingly. Moreover, Inverse Distance Weighted (IDW) interpolation method was used to make an assessment map of soil environmental quality based on the Nemerow's pollution index and the soil environmental quality was categorized into five grades. Moreover, ten indices were calculated as input parameters for Principal Component Analysis (PCA) and the principal components (PCs) were created to compare environmental quality of different soils and regions. The results revealed that environmental quality of tea soils was better than that of paddy soils, vegetable soils and fruit soils. This study indicated that GIS combined with multivariate statistical approaches proved to be effective and powerful tool in the mapping of soil contaminations distribution and the assessment of soil environmental quality on provincial scale, which is benefited to environmental protection and management decision-making by local government.

    Ethanol production from wheat has become an emerging economic activity in Henan Province due to the establishment in 2001 of the National Program for Alcohol Production. The program aimed at facing the unfolding world energy crisis in the near future and increasing China's energy security. Instead, in spite of claims for 'green energy', such an activity is likely to generate great environmental damage and social problems. Moreover, the international market prices for raw materials (especially cereals) and fossil oil are putting this activity under siege. This research presents an energy and eMergy analysis of a typical wheat plantation/alcohol distillery system, in the Henan Province. Comparison is drawn with bioethanol production in Italy, based on corn from intensive, industrialized agriculture. Energy and eMergy indices of ethanol production from wheat and corn in the two agro-industrial systems are respectively as follows: output/input energy ratio, 1.09 (wheat) and 1.19 (corn); transformity of bioethanol, 2.77 x 105 and 1.89 x 105 seJ/J; renewability, 20% and 11%; eMergy yield ratio, 1.24 and 1.14; environmental loading ratio, 4.05 and 7.84; and finally eMergy sustainability index, 0.31 and 0.15. Results show that bioethanol from food crops is not a sustainable source of fuel. (author)

    This paper uses Moderate Resolution Imaging Spectroradiometer (MODIS) data to investigate the spatial and temporal variations of aerosol optical thickness (AOT) over Guangdong, the most developed province in China, during 2010-2012. Linear regression and self-organizing maps (SOM) are used to investigate the relationship between AOT and its affecting factors, including Normalized Difference Vegetation Index (NDVI), elevation, urbanized land fraction, and several socio-economic variables. Results show that the highest values of τ0.55 mainly occur over the rapidly-developing Pearl River Delta (PRD) region and the eastern coast. Seasonal averaged AOT is highest in summer (0.416), followed by spring (0.351), winter (0.292), and autumn (0.254). From unary linear regression and SOM analysis, AOT is shown to be strongly negatively correlated to NDVI (R2 = 0.782) and elevation (R2 = 0.731), and positively correlated with socio-economic factors, especially GDP, industry and vehicle density (R2 above 0.73), but not primary industry. Multiple linear regression between AOT and the contributing factors shows much higher R2 values (>0.8), indicative of the clear relationships between AOT and variables. This study illustrates that human activities have strong impacts on aerosols distribution in Guangdong Province. Economic and industrial developments, as well as vehicle density, are the main controlling factors on aerosol distribution.

    To understand pollution level and possible sources ofatmospheric fine particulates in rural areas of southern Jiangsu Province of China, samples of PM2.5 were collected and analyzed in Xueyan Town and Taihu Lake Station over three seasons from July 2002 to January 2003. The mass concentrations of PM2.5 and 14 principal component elements were obtained. The results showed that pollution of PM2.5 was serious and the concentration levels of S, Zn, Pb and As were similar to city. There are different seasonal distribution laws of pollutant elements in PM2.5 between two sampling sites, probably due to contribution of local sources, medium or long distance transportation of fine particulates and complicated meteorological conditions. The enrichment levels of S, Zn, Pb, As, K were high,reflecting the influence of anthropogenic activities. Particularly enrichment level of S was much higher in summer, which was probably related to meteorological condition. The result of principal components analysis showed major sources of PM2.5 included crustal resuspension, coal burning, metal processing industry or waste incineration, vehicular emission, which suggests anthropogenic activities is of important influence on PM2.5 in rural areas of southem Jiangsu Province.

    County-level industrial development and structure upgrade is one of the most important issues of revitaliz-ing old industrial base of China. ARer the cluster analysis on GDP per capita and GDP per area of each county inLiaoning Province, this paper finds the similarity of population size, land use intensity, and economic development ofeach county. Location quotient reflects the specialization intensity of industries in each county, and it also reflects thespatial differences of county-level industrial development. Economic development level is higher in the southeast thanin the northwest of Liaoning, and the industry driving effect on county-level economy is apparent. The main influenc-ing factors include location, industrial foundation and economic system reform, capital input level, knowledge andtechnology dissemination, conditions of domestic and overseas markets, population and labor force transfer. Industri-alization is an important approach to urbanization for the counties in Liaoning Province. The proportion of agricultureis much higher in the northwest than in the southeast of Liaoning, so it will be take longer time for counties in thenorthwest of Liaoning to make industrialization, urbanization and modernization.

  8. Charnockite Formation and Early Precambrian Crust Evolution in Yishui Area, Shandong Province, China

    2000-01-01

    Charnockite and granulite in Yishui area, Shandong Province are located in the middle part of the Tancheng-Lujiang fault zone, eastern China. Field studies have shown that the charnockites, derived from the adjacent granulites, are classified as three types: enderbite, garnet-enderbite and hypersthene-trondhjemite. In addition, two generations of minerals are present in the charnockites: the relic minerals such as garnet, hypersthene and clinopyroxene, and the neocrystallized minerals such as plagioclase and K-feldspar. The relic minerals occurring in the granulite facies stage were affected by the later partial melting. The relic minerals, irregular and usually ragged in shape, occupy the interstitial positions in the neocrystalline minerals. The neocrystalline minerals are usually euhedral-subhedral crystals. The study of petrology, mineralogy and geochemistry of charnokites concludes that the enderbite was formed by the anatexis of the two-pyroxene plagioclase granulite, that the garnet-enderbite was formed by the anatexis of sillimanite garnet gneiss, and that the hypersthene-trondhjemite was formed by the anatexis of the leucocratic two-pyroxene plagioclase granulite. The U-Pb dating of the zircon indicates that the formation of the charnockite and granulite was related to the Archean-Proterozoic upwelling of a mantle plume (hot spot)around 2 500 Ma, in Yishui area, Shandong Province.

    Yunnan Province of China is one of the important centers for origin and evolution of cultivated rice worldwide.Wild rice is the ancestor of the cultivated rice.Many elite traits of wild rice have widened the genetic basis in cultivated rice.However,many populations of wild rice species have disappeared in the past few years.Therefore,the current status of wild rice resources should be updated and the genetic diversity of wild rice species should be examined for further germplasm preservation and utilization.Our investigations showed that the number of natural wild rice populations declined sharply in Yunnan Province during the past few years due to various reasons.Fortunately,one population of Oryza rufipogon,three of O.officinalis and ten of O.granulata have been newly found in different ecological sites,which were confirmed by inter-simple sequence repeat (ISSR) marker analysis in this study.ISSR analysis and investigation of some important traits of nutritional values indicated that the genetic diversity of the currently existing wild rice resources in Yunnan is still rich.The demonstration of genetic diversity of wild rice by a combined use of geographical distribution,morphological traits,nutrition contents and ISSR markers would be helpful for the conservation and exploration of these important wild rice resources.

  11. Energy and eMergy evaluation of bioethanol production from wheat in Henan Province, China

    Ethanol production from wheat has become an emerging economic activity in Henan Province due to the establishment in 2001 of the National Program for Alcohol Production. The program aimed at facing the unfolding world energy crisis in the near future and increasing China's energy security. Instead, in spite of claims for 'green energy', such an activity is likely to generate great environmental damage and social problems. Moreover, the international market prices for raw materials (especially cereals) and fossil oil are putting this activity under siege. This research presents an energy and eMergy analysis of a typical wheat plantation/alcohol distillery system, in the Henan Province. Comparison is drawn with bioethanol production in Italy, based on corn from intensive, industrialized agriculture. Energy and eMergy indices of ethanol production from wheat and corn in the two agro-industrial systems are respectively as follows: output/input energy ratio, 1.09 (wheat) and 1.19 (corn); transformity of bioethanol, 2.77x105 and 1.89x105 seJ/J; renewability, 20% and 11%; eMergy yield ratio, 1.24 and 1.14; environmental loading ratio, 4.05 and 7.84; and finally eMergy sustainability index, 0.31 and 0.15. Results show that bioethanol from food crops is not a sustainable source of fuel

    In the present study, the occurrence and contamination levels of eight mycotoxins were investigated in wheat flour samples (n = 359) from Shandong Province of China. Samples were determined using a multi-mycotoxin method based on isotope dilution ultrahigh performance liquid chromatography-tandem mass spectrometry. The results indicated that the most frequently found mycotoxins were deoxynivalenol (DON) (97.2%), nivalenol (40.4%) and deoxynivalenol-3-glucoside (33.4%), and mean contamination levels in positive samples were 86.7, 3.55 and 3.34 µg kg(-1), respectively. The obtained data were further used to estimate the daily intake of the local population, and indicated that wheat flour consumption contributes little to DON exposure. However, with the aim to keep the contamination levels under control and to establish a more precise evaluation of the mycotoxin burden in Shandong Province, more sample data from different harvest years and seasons are needed in the future.

    Shanxi Province is a region with frequent occurrence of earthquakes, floods and waterlogging, meteorological and geologic hazards, and agrobiohazards in China. The study shows that the formation and development of the down-faulted basin zone in Shanxi Province provides an available condition for preparation and occurrence of these hazards, so that the basin zone becomes an area with frequent occurrence of the hazards, such as earthquakes, floods and waterlogging, meteorological and geologic hazards and agrobiohazards in Shanxi and with their most serious interaction and mutual intensification. Moreover, the basin zone is an area with dense population and most concentrated industrial and agricultural productions and social-economic property in Shanxi. The comprehensive effect of the two factors caused the zone to be a high natural disaster risk area in Shanxi. For reduction of natural disasters and ensuring the sustainable social-economic development in Shanxi, it is necessary to regard the basin zone as an important area for disaster reduction in Shanxi and to carry out integrated disaster reduction.

    Chengjing Nie

    Full Text Available BACKGROUND: In the past decade, bacillary dysentery was still a big public health problem in China, especially in Guangxi Province, where thousands of severe diarrhea cases occur every year. METHODS: Reported bacillary dysentery cases in Guangxi Province were obtained from local Centers for Diseases Prevention and Control. The 14 socio-economic indexes were selected as potential explanatory variables for the study. The spatial correlation analysis was used to explore the associations between the selected factors and bacillary dysentery incidence at county level, which was based on the software of ArcGIS10.2 and GeoDA 0.9.5i. RESULTS: The proportion of primary industry, the proportion of younger than 5-year-old children in total population, the number of hospitals per thousand persons and the rates of bacillary dysentery incidence show statistically significant positive correlation. But the proportion of secondary industry, per capital GDP, per capital government revenue, rural population proportion, popularization rate of tap water in rural area, access rate to the sanitation toilets in rural, number of beds in hospitals per thousand persons, medical and technical personnel per thousand persons and the rate of bacillary dysentery incidence show statistically significant negative correlation. The socio-economic factors can be divided into four aspects, including economic development, health development, medical development and human own condition. The four aspects were not isolated from each other, but interacted with each other.

    Full Text Available BACKGROUND: Although confinement in drug detoxification ("detox" and re-education through labor (RTL centers is the most common form of treatment for drug dependence in China, little has been published about the experience of drug users in such settings. We conducted an assessment of the impact of detention on drug users' access to HIV prevention and treatment services and consequent threats to fundamental human rights protections. METHODS AND FINDINGS: Chinese government HIV and anti-narcotics legislation and policy documents were reviewed, and in-depth and key informant interviews were conducted with 19 injection drug users (IDUs and 20 government and nongovernmental organization officials in Nanning and Baise, Guangxi Province. Significant contradictions were found in HIV and antinarcotics policies, exemplified by the simultaneous expansion of community-based methadone maintenance therapy and the increasing number of drug users detained in detox and RTL center facilities. IDU study participants reported, on average, having used drugs for 14 y (range 8-23 y and had been confined to detox four times (range one to eight times and to RTL centers once (range zero to three times. IDUs expressed an intense fear of being recognized by the police and being detained, regardless of current drug use. Key informants and IDUs reported that routine HIV testing, without consent and without disclosure of the result, was the standard policy of detox and RTL center facilities, and that HIV-infected detainees were not routinely provided medical or drug dependency treatment, including antiretroviral therapy. IDUs received little or no information or means of HIV prevention, but reported numerous risk behaviors for HIV transmission while detained. CONCLUSIONS: Legal and policy review, and interviews with recently detained IDUs and key informants in Guangxi Province, China, found evidence of anti-narcotics policies and practices that appear to violate human rights

  16. Estimations of distribution and zoning for air temperature using satellite data over Liaoning province, China

    International Nuclear Information System (INIS)

    The distribution and zoning of air temperature over Liaoning Province, China were examined using the calculated values of air temperature derived from satellite data (GMS data) as well as from altitude data. The results are summarized as follows. At 02:00 LST the correlation coefficients for the air temperatures calculated from altitude compared with the observed air temperatures were the same as those of the air temperatures derived from GMS data. At 14:00 LST, however, the correlation coefficients for air temperatures calculated from altitude were less than those of the air temperatures derived from GMS data. This fact verifies that the distribution of air temperature in the day-time is affected by other factors than altitude. The distribution of air temperature in a cell of approximately 5'(latitude) x 7.5'(longitude) over Liaoning Province, china was estimated by using the regression equations between surface temperature derived from GMS and the observed air temperature. The distribution of air temperature was classified into 5 types, and the types are obtained at 14:00 LST are seasonal ones but the types at 02:00 LST are not related to season. Also, the regional classification for the air temperature was examined using this distribution of air temperature. This regional classification for the air temperature was similar to the published zoning of the agricultural climate. It became clear that the characteristic distribution of air temperature in a cell unit can be obtained by satellite data. And it is possible to define the zoning of air temperature for a cell unit by the accumulated analyses of satellite data over an extended period

    Precipitation is an important climatic parameter, and its variability severely affects regional hydrological processes and water resource management. In order to explore the changing spatial and temporal characteristics of precipitation-related indices, including precipitation amounts indices, extreme precipitation indices, and precipitation concentration indices, in Hubei province, central China during 1961-2010, several precipitation-related indices series were analyzed using the Mann-Kendall test, Pettitt test, and inverse distance weighted interpolation method in this paper. The results are as follows: (1) A clear south-north gradient is apparent in the spatial distribution of the majority of precipitation-related indices, while the distribution of other indices (i.e., CDD, PCD, and PCP) is just the opposite. Most part of Hubei province can experience mixed positive and negative trends in precipitation-related indices. (2) The majority of precipitation-related indices exhibit an increasing trend, but most of which are not significant. July has the largest positive trend, with a regional average of 14.76 mm/decade. As for extreme precipitation indices, there exist large variations in Hubei, especially in R95pTOT. Besides, no obvious trends are shown in precipitation concentration indices. (3) With the exception of consecutive dry days (CDD), most of extreme precipitation indices are strongly correlated with annual mean precipitation (AMP) in Hubei. And the extreme precipitation indices are well correlated with each other except CDD and consecutive wet days (CWD). For six precipitation-related indices (i.e., SDII, RX1day, RX5day, R95pTOT R99pTOT, and PCD), there are significant positive relationships with Northern Hemisphere Subtropical High (NHSH) but significant negative relationships with Northern Hemisphere Polar Vortex (NHPV). Furthermore, the majority of precipitation-related indices have significant negative correlations with East Asian summer monsoon

    Coal mining safety has been compromised with water inrushes from aquifers either overlying or underlying the coal seams. Detailed studies of the associated hydrogeological conditions in China have led to different approaches to mitigate the water inrush risks from these two types of aquifers—the `three diagram method' for overlying-aquifer water inrushes and the `vulnerability index method' for underlying-aquifer water inrushes. The `three diagram method' consists of: (1) aquifer water-abundance distribution charts derived from a geographic information system and analytic hierarchy process based water-abundance index model; (2) a fracture height map showing mining-induced fractures above the coal seam, established with stratified numerical simulations; and (3) a comprehensive partition map identifying the overlying-aquifer water inrush risk. The `vulnerability index method' uses site-specific data to establish thematic maps for major factors that affect the underlying-aquifer water inrushes, whereas the weight of each control factor is determined by the analytic hierarchy process. The calculated vulnerability index is indicative of water inrush risks. The effectiveness of these methods is illustrated with a case study at the Pingshuo No. 1 underground coal mine, Shanxi Province, China.

    In this paper, two ancient thin-walled bronze vessels unearthed in Anlu County of Hubei Province, China, were studied systematically by using optical microscopy (OM), scanning electron microscope (SEM), energy dispersive spectrometer (EDS), electron backscatter diffraction (EBSD) and nanoindentation system, and also we calculated the Sn diffusion in a Cu substrate based upon the substitutional mechanism at high temperature. The results indicated that the vessels were possibly fabricated using the following processes: (1) alloying the high-tin Cu-Sn bronze; (2) casting the preliminary shape of the vessels; (3) forging the vessels in the temperature range of 586-798 ∘C; (4) simply wiping tinning on the surface of the vessel at high temperature; (5) quenching the vessels to room temperature; and (6) at last, grinding and polishing the surface of the vessels. It seems that the present thin-walled bronze vessels provide an evidence of the spread of thin-walled high-tin bronze technology in China and its surrounding regions.

  2. Energy-saving decomposition and power consumption forecast: The case of Liaoning province in China

    International Nuclear Information System (INIS)

    To achieve sustainable development of the society, the People's Republic of China (PRC) proposed in its 11th Five-Year Plan for National Economic and Social Development Program a shift in energy-saving target of decreasing energy intensity by 20% in 2010 compared with that of 2005. Liaoning province is one of the oldest industrial bases in China. Policymakers are often confronted with problems relating to adjustment in the development pattern as a means to secure steady economic growth. The power industry is a fundamental energy industry; it plays an important role in realizing of energy-saving targets. Based on the input-output model, this paper sets extensive, planning and 20% energy-saving scenarios in order to analyze energy-saving and power consumption situations for Liaoning by 2010. Through extensive simulations, the levels of energy-saving and power demand under different scenarios are obtained. Results from the analysis show that under the premises of adjusting the ratio of investment and consumption, optimizing products structure, and improving energy use efficiency, it is possible to achieve the proposed energy-saving target. Liaoning's power consumption can maintain a stable growth trend in the future. The percentage of electricity to the total energy use can also increase to 16% in 2010.

    Concentrations of copper (Cu), lead (Pb), chromium (Cr), mercury (Hg), and arsenic (As) were measured in arid agricultural and irrigated agricultural soils collected in Daba Village, Shajiawuan Village, Gangou Village and Sifangwu Village, located in central Gansu Province, China. Concentrations except Hg and Pb were lower than the background values in grey calcareous soil in the selected arid agricultural soils. Pb concentration exceeded the threshold of arid agricultural soils in China by 72. 46%. These results showed that there was indeed serious pollution with Pb, a slight pollution problem for other selected metals in the irrigated agricultural soils in Daba Village. Principal component analysis (PCA) was used to assess the soil data, applying varimax rotation with Kaiser Normalization. The result showed that the irrigated factor, agricultural factor and anthropogenic factor all contributed to the relations between selected chemical properties. The main factor of accumulation of Cu, Pb, Cr, Hg and As was lithological factor in arid agricultural areas. There is a striking dissimilarity of origin of Cu, Pb, Cr, Hg and As in agricultural soil between the irrigate agriculture and arid agriculture.

    Cenozoic basalts from the Linqu County, Shandong Province, China entrain some clinopyroxene crystals, of which many contain abundant glass melt inclusions. These melt inclusions are extremely irregular in shape with most grain sizes in a range of 10-50 μm and coexist with low-Mg# olivines, labradorites and Ca-rich potassium feldspars. In-situ major and trace element analyses show that the glass melt inclusions are high in alkalis (Na2O+K2O > 10 wt%), SiO2 (>54 wt%), CaO and FeO (>4 wt%), but low in MgO (Mg# < 20), and have LREE enrichments ((Ce/Yb)cn = 11.6-16.4) and apparently positive Eu anomalies (Eu/Eu*>2), thus having phonolitic compositions. The compositional features of clinopyroxene crystals, glass melt inclusions and their coexistent minerals suggest that these melt inclusions were exotic melts in clinopyroxenes trapped prior to their entrainment in the host basalt. The discovery of these melt inclusions provides a new approach to further investigating the evolution of Meso- zoic lithospheric mantle beneath the southeastern North China Craton.

  5. Bioenergy consumption in rural China: Evidence from a survey in three provinces

    International Nuclear Information System (INIS)

    Biomass in the form of crop residues and firewood is a major energy source for rural households in China. A survey conducted in the provinces of Shanxi, Zhejiang, and Guizhou shows that 37 percent of rural households use bioenergy for heating and cooking and that bioenergy accounts for 18 percent of their total energy consumption. Most of the biomass used for energy is burned in traditional stoves, contributing to indoor air pollution in rural homes. Crop residues also are commonly burned in the fields, contributing to the high level of outdoor air pollution in China. Our econometric analysis of the key determinants of bioenergy use shows that bioenergy consumption falls modestly with income growth, increased time required for biomass collection, and less farmland. Hence, open burning of some biomass is an optimal choice and is likely to become more of a problem without policy intervention. These findings suggest that a more sustainable use of biomass requires policies that promote cleaner, more efficient bioenergy combustion technologies and increase the economic value of biomass such that local households can benefit from biomass collection. - Highlights: • Nearly 40 percent of rural households surveyed in 2010 and 2011 use bioenergy. • Bioenergy accounts for nearly 20 percent of total energy used by rural households. • Income growth of 5 percent results in less than 1 percent reduction in bioenergy use. • The high opportunity cost of biomass collection reduces bioenergy use. • Sustainable policy for bioenergy use must benefit local households

    Thyroid diseases(TD) can be induced by either deficient or excessive iodine intake. Universal Salt Iodization(USI) program has been implemented in China since 1995, to prevent iodine deficiency disorders (IDD). To evaluate the current conditions of TD and the role of USI, a multi-stage stratified random sampling scheme was used to perform a cross-sectional survey on the incidence of TD among participants in 6600 households in Zhejiang Province, a coastal area in China. Iodine nutrition status of the population was assessed by dietary iodine intake recall and urinary iodine concentration (UIC) of the participants, and TD were diagnosed by thyroid ultrasonography for 15122 participants and for 5873 participants by serum criteria for thyroid function(fT3, fT4, TSH, TRAb, TgAb, TPOAb; see Introduction for abbreviations). The median UIC of the surveyed population was 163μg iodine/L. From the participants 23.2% had UIChyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, Graves' disease and chronic lymphocytic thyroiditis was 0.5%, 0.6%, 0.6%, 7.8%, 0.2% and 0.3%, respectively. The proportion of several TD for participants with non-iodized salt intake was higher than that for participants with iodized salt intake. PMID:27259353

    To identify township-level high-risk foci of malaria transmission in Yunnan Province, China, along the international border, we retrospectively reviewed data collected in hospitals and clinics of 58 townships in 4 counties during 2011-2013. We analyzed spatiotemporal distribution, especially hot spots of confirmed malaria, using geographic information systems and Getis-Ord Gi*(d) cluster analysis. Malaria incidence, transmission seasonality, and Plasmodium vivax:P. falciparum ratio remained almost unchanged from 2011 to 2013, but heterogeneity in distribution increased. The number of townships with confirmed malaria decreased significantly during the 3 years; incidence became increasingly concentrated within a few townships. High-/low-incidence clusters of P. falciparum shifted in location and size every year, whereas the locations of high-incidence P. vivax townships remained unchanged. All high-incidence clusters were located along the China-Myanmar border. Because of increasing heterogeneity in malaria distribution, microgeographic analysis of malaria transmission hot spots provided useful information for designing targeted malaria intervention during the elimination phase.

    Here we report on three new species of ornithuromorph birds from the Lower Cretaceous Xiagou Formation in the Changma Basin of Gansu Province, northwestern China: Yumenornis huangi gen. et sp. nov., Changmaornis houi gen. et sp. nov., and Jiuquanornis niui gen. et sp. nov.. The last of these is based on a previously published but unnamed specimen: GSGM-05-CM-021. Although incomplete, the specimens can be clearly distinguished from each other and from Gansus yumenensis Hou and Liu, 1984. Phylogenetic analysis resolves the three new taxa as basal ornithuromorphs. This study reveals previously unrecognized ornithuromorph diversity in the Changma avifauna, which is largely dominated by Gansus but with at least three other ornithuromorphs. Body mass estimates demonstrate that enantiornithines were much smaller than ornithuromorphs in the Changma avifauna. In addition, Changma enantiornithines preserve long and recurved pedal unguals, suggesting an arboreal lifestyle; in contrast, Changma ornithuromorphs tend to show terrestrial or even aquatic adaptions. Similar differences in body mass and ecology are also observed in the Jehol avifauna in northeastern China, suggesting niche partitioning between these two clades developed early in their evolutionary history.

    Full Text Available Abstract Background Rabies is a major public-health problem in developing countries such as China. Although the recent re-emergence of human rabies in China was noted in several epidemiological studies, little attention was paid to the reasons behind this phenomenon paralleling the findings of the previous reports. The purpose of this study is thus first to characterize the current trends of human rabies in China from 1990 to 2007, and then to define better recommendations for improving the post-exposure prophylaxis (PEP schedules delivered to rabies patients. Methods The most updated epidemiological data for 22527 human rabies cases from January 1990 to July 2007, retrieved from the surveillance database of reportable diseases managed by the Ministry of Health of China, were analysed. To investigate the efficiency for the post-exposure treatment of rabies, the details of 244 rabies patients, including their anti-rabies treatment of injuries or related incidents, were ascertained in Guangdong provincial jurisdiction. The risk factors to which the patients were predisposed or the regimens given to 80 patients who received any type of PEP were analysed to identify the reasons for the PEP failures. Results The results from analysis of the large number of human rabies cases showed that rabies in China was largely under control during the period 1990–1996. However, there has been a large jump in the number of reported rabies cases since 2001 up to a new peak (with an incidence rate of 0.20 per 100000 people that was reached in 2004, and where the level has remained until present. Then, we analysed the PEP in 244 rabies cases collected in the Guangdong province in 2003 and 2004, and found that 67.2% of the patients did not seek medical services or did not receive any PEP. Further analysis of PEP for the 80 rabies patients who received any type of PEP indicated that almost all of the patients did not receive proper or timely treatment on the wounds

    Full Text Available Abstract Background The tuberculosis register is a critical data source for the information system of national tuberculosis control programs. From the information in the tuberculosis case register, it is possible to extend the standard analysis of age and sex characteristics among sputum smear-positive cases to all tuberculosis case categories. National tuberculosis programs might utilize such information to identify problems related to referral and access to diagnosis and treatment. Objectives Based on the electronic database we created, our objectives were to provide a detailed description of age and sex characteristics of tuberculosis patients at registration and to provide a comparison of age-specific sex characteristics among incident and prevalent sputum smear-positive cases. Methods A representative sample of tuberculosis case registers from 1 January 2003 to 31 December 2005 was selected in Cambodia, two provinces in China and Viet Nam. Age and sex characteristics of cases in the three separate prevalence surveys in the three jurisdictions (Cambodia: year 2002; China: year 2000; and Viet Nam: year 2006-2007 were obtained for comparison. Results A total 37,635 patients had been registered during the period in the selected units in the three countries. Cases were more frequently male in all three countries with 53%, 71%, and 69% in Cambodia, China, and Viet Nam, respectively. The ratios of the female-to-male odds in the notification system to that in the prevalence survey in smear-positive cases in Cambodia, China and Viet Nam were 2.1, 0.9, and 1.8, respectively. Because of the small proportion of extrapulmonary tuberculosis registered in China, we limited the analysis on age and sex distribution for extrapulmonary cases to Cambodia and Viet Nam. The proportion with extrapulmonary tuberculosis among all cases was 18.5% in Cambodia and 15.7% in Viet Nam, decreasing in frequency with increasing age. Conclusions Characteristics of patients

    Full Text Available Semen samples were collected from 1213 fertile men whose partners had a time-to-pregnancy (TTP ≤12 months in Guangdong Province in Southern China, and semen parameters including semen volume, sperm concentration, total counts, motility, and morphology were evaluated according to the World Health Organization (WHO 2010 guideline. All semen parameters analyzed were normal in ~62.2% of the total samples, whereas ~37.8% showed at least one of the semen parameters below normal threshold values. The fifth centiles (with 95% confidence intervals were 1.3 (1.2-1.5 ml for semen volume, 20 × 10 6 (18×10 6 -20×10 6 ml−1 for sperm concentration, 40 × 10 6 (38×10 6 -44×10 6 per ejaculate for total sperm counts, 48% (47%-53% for vitality, 39% (36%-43% for total motility, 25% (23%-27% for sperm progressive motility, 5.0% (4%-5% for normal morphology. The pH values ranged from 7.2 to 8.0 with the mean ± standard deviation at 7.32 ± 0.17. No effects of age and body mass index were found on semen parameters. Occupation, smoking and alcohol abuse, varicocele appeared to decrease semen quality. Sperm concentration, but not sperm morphology, is positively correlated with TTP, whereas vitality is negatively correlated with TTP. Our study provides the latest reference values for the semen parameters of Chinese fertile men in Guangdong Province, which are close to those described in the new WHO guidelines (5 th Edition.

    Cultivar selection is important for alfalfa (Medicago sativa L.) hay production. From 2009 to 2012, a ifeld study was conducted to evaluate the dry matter yield (DMY) of 28 cultivars in Cangzhou District of Hebei province, China, and to determine the most suitable cultivars for this province and other zones with similar climate conditions. 28 alfalfa cultivars were sown in late March of 2009 and were harvested for hay four times in each subsequent year. The results showed that the climatic conditions resulted in signiifcant differences in annual DMY among years, with the second year being the highest and the ifrst year the lowest. The top ifve cultivars with the highest total DMY were L2750 (62.75 t ha-1), Horn (62.72 t ha-1), 86-266 (61.55 t ha-1), German (61.44 t ha-1) and Zhongmu 1 (61.18 t ha-1), respectively. Across all four years, ifrst harvest had the highest ratios to annual DMY except the cultivar of Rambler, while the fourth harvest had the lowest ratio. There were positive correlation relationships between DMY of each harvest and annual DMY, and the correlation coefifcients were all signiifcant in four years. And the path coefifcients of ifrst harvest were always the highest in four years. The qualities showed small variations among these cultivars and the cultivar L3750 presented the highest crude protein in both years. Crude protein had signiifcant positive correlation with relative feed value (RFV) in both years while crude ifber had signiifcant negative correlation with RFV and crude ifber.

    Orientia tsutsugamushi, the causative agent of scrub typhus, is an obligate intracellular bacterium and characterized by dramatic genetic diversity. To elucidate the genotypes of O. tsutsugamushi populating in patients in Shandong Province, a new epidemic zone in China, we sequenced partial of the 56-kDa type-specific antigen gene (TSA) and identified the genotypes of 43 O. tsutsugamushi samples from human patients confirmed with scrub typhus from 2010 to 2013. All of the 43 sequences are in the same clade, 39 of them are in one branch and the other four sequences, nominated as SH1002, SH1306, SH1309, and SH1307 are in four separate branches. To clarify the clinical characterizations caused by Kawasaki-related genotypes, we studied the clinical profiles of these 43 scrub typhus patients. Most patients (88.1%) were farmers lived in rural areas. They presented with fever (100.0%), headache (79.1%), dizziness (32.6%), generalized myalgia (48.8%), fatigue (53.5%), anorexia (53.5%), facial flushing (23.3%), conjunctival congestion (11.6%), skin rashes (58.1%) and lymphadenopathy (23.3%). Eschar (97.7%) was quite common in patients, which provided doctors with a luminous clue for diagnosis of scrub typhus. Thrombocytopenia was seen in 23.1% of patients, and three patients (7.0%) had bronchopneumonia. There was no death report in Shandong Province during the study period. The present study provides beneficial data for clinical, serological, and molecular diagnosis of scrub typhus infections, and also provides foundations for subsequent studies. PMID:25575441

    Fumonisin B1 (FB1) and fumonisin B2 (FB2) are the most abundant fumonisins (FBs) occurring worldwide in maize, infected mainly by Fusarium verticillioides and F. proliferatum. A total of 307 corn kernel samples were collected from 45 districts of Gansu, Shandong, Ningxia and the Inner Mongolia provinces of the north and northwest China. The samples were analysed for FB1 and FB2 by high-performance liquid chromatography. The FBs (FB1+ FB2) incidence rate in samples from Gansu, Shandong, Ningxia and Inner Mongolia were 31.5%, 81.1%, 46.2% and 53.6%, respectively. Average FBs concentration was 703 μg/kg and the concentrations ranged from ≤11 to 13,110 μg kg(-1). Results were compared with the European Commission (EC) regulation for FB1+ FB2 in unprocessed maize for human consumption of 4 mg kg(-1). Contamination in 17 samples was higher than these levels. More than 80% of the samples from Liaocheng county, which is located in the Shandong province, were contaminated with FBs, with a mean total FB concentration of 2496 μg/kg. The result was significantly different from that of the Inner Mongolia (1399 μg/kg), Ningxia (373 μg/kg) and Gansu (175 μg/kg). Average exposure to FBs (0.12 μg/kg body weight/day) is within the provisional maximum tolerable daily intake of 2.0 mg/kg of body weight set by the Joint Food and Agriculture Organization and World Health Organization Expert Committee on Food Additives.

    Full Text Available OBJECTIVE: To investigate the levels of primary health care services for children and their changes in Zhejiang Province, China from 1998 to 2011. METHODS: The data were drawn from Zhejiang maternal and child health statistics collected under the supervision of the Health Bureau of Zhejiang Province. Primary health care coverage, hospital deliveries, low birth weight, postnatal visits, breastfeeding, underweight, early neonatal (<7 days mortality, neonatal mortality, infant mortality and under-5 mortality were investigated. RESULTS: The coverage rates for children under 3 years old and children under 7 years old increased in the last 14 years. The hospital delivery rate was high during the study period, and the overall difference narrowed. There was a significant difference (P<0.001 between the prevalence of low birth weight in 1998 (2.03% and the prevalence in 2011 (2.71%. The increase in low birth weight was more significant in urban areas than in rural areas. The postnatal visit rate increased from 95.00% to 98.45% with a significant difference (P<0.001. The breastfeeding rate was the highest in 2004 at 74.79% and lowest in 2008 at 53.86%. The prevalence of underweight in children under 5 years old decreased from 1.63% to 0.65%, and the prevalence was higher in rural areas. The early neonatal, neonatal, infant and under-5 mortality rates decreased from 6.66‰, 8.67‰, 11.99‰ and 15.28‰ to 1.69‰, 2.36‰, 3.89‰ and 5.42‰, respectively (P<0.001. The mortality rates in rural areas were slightly higher than those in urban areas each year, and the mortality rates were lower in Ningbo, Wenzhou, and Jiaxing regions and higher in Quzhou and Lishui regions. CONCLUSION: Primary health care services for children in Zhejiang Province improved from 1998 to 2011. Continued high rates of low birth weight in urban areas and mortality in rural areas may be addressed with improvements in health awareness and medical technology.

  1. Evaluating the water footprint of the energy supply of Liaoning Province, China: A regional input–output analysis approach

    International Nuclear Information System (INIS)

    Water and energy are important resources for regional economies and are inextricably and reciprocally linked. Global water and energy demand will increase significantly by 2030 while climate change will worsen water availability. Thus, it is important to ensure a sustainable energy supply despite the increasing severity of water resource constraints. Numerous studies have analyzed water requirements to produce energy from production perspectives. However, energy is generally supplied by both internal and external producers. Thus, it is necessary to consider the availability of water to produce energy from consumption perspectives also. We evaluate the water footprint of the energy supply of Liaoning Province, China. We apply the standard top-down approach using an input–output framework. We estimate the water footprint of the energy supply of Liaoning Province at 854 million m3 in 2002, with 47% of water used for electricity and heating. Our results reveal that energy supply could depend on water resources in neighboring provinces; external producers met 80% of the water footprint of energy supply, although only 35% of energy supply was imported. If Liaoning Province decreased its external dependency, withdrawal of available water resources within the province would increase from 86% to 91%. To guarantee future regional energy security, it is important to manage water resources effectively through water-efficient electricity generation and by allocating water resources among sectors. - Highlights: • We assess the water footprint of energy supply (WFES) for Liaoning Province, China. • The WFES for 2002 was 854 million m3, with 47% used for electricity and heating. • External sources accounted for 80% of the WFES and 47% of the energy supply. • Without energy imports, water resource withdrawal would increase from 86% to 91%. • Effective water resource management is important for regional energy security

    Full Text Available BACKGROUND: Acute respiratory infections (ARIs are the leading cause of children and their leading killer. ARIs are responsible for at least six percent of the world's disability and death. Viruses are one of the most common agents causing ARIs. Few studies on the viral etiology and clinical characteristics of ARIs have been performed in the northwest region of China, including Gansu Province. METHODS: Clinical and demographic information and throat swabs were collected from 279 patients from January 1st to December 30st, 2011. Multiplex RT-PCR was performed to detect 16 respiratory viral pathogens. RESULTS: 279 patients were admitted for ARIs. The patients aged from 1 month to 12 years, with the median age of 2 years. Of which, 105 (37.6% were positive for at least one pathogen. A total of 136 respiratory viral pathogens were identified from the 105 patients. Respiratory syncytial virus (RSV was the most frequently detected pathogen (26.5%, 36/136, followed by parainfluenza virus (PIV 1-3 (22.1%, 30/136, human rhinovirus (HRV (21.3%, 29/136, human coronavirus (CoV (10.3%, 14/136 and human adenovirus (HAdV (9.6%, 13/136. Influenza A (Flu A, human metapneumovirus (hMPV and human bocavirus (BoCA were found 4.4%, 3.7% and 2.2%, respectively. Influenza B (Flu B and seasonal influenza A H1N1(sH1N1 were not detected. Single-infections were detected in 30.5% (85/279 of cases. RSV was the most common pathogens in patients under 1 year and showed seasonal variation with peaks during winter and spring. CONCLUSIONS: This paper presents data on the epidemiology of viral pathogens associated with ARIs among children in Gansu Province, China. RSV is most frequently detected in our study. The findings could serve as a reference for local CDC in drawing up further plans to prevent and control ARIs.

    Full Text Available OBJECTIVE: To measure the prices and availability of selected medicines in Shaanxi Province after the implementation of new healthcare reform in 2009. METHODS: Data on the prices and availability of 47 medicines were collected from 50 public and 36 private sector medicine outlets in six regions of Shaanxi Province, Western China using a standardized methodology developed by the World Health Organization and Health Action International from September to October 2010. Medicine prices were compared with international reference prices to obtain a median price ratio. Affordability was measured as the number of days' wages required for the lowest-paid unskilled government worker to purchase standard treatments for common conditions. FINDINGS: The mean availabilities of originator brands and lowest-priced generics were 8.9% and 26.5% in the public sector, and 18.1% and 43.6% in the private sector, respectively. The public sector procured generics and originator brands at median price ratios of 0.75 and 8.49, respectively, while patients paid 0.97 and 10.16. Final patient prices for lowest-priced generics and originator brands in the private sector were about 1.53 and 8.36 times their international retail prices, respectively. Public sector vendors applied high markups of 30.4% to generics, and 19.6% to originator brands. In the private sector, originator brands cost 390.7% more, on average, than their generic equivalents. Generic medicines were priced 17.3% higher in the private sector than the public sector. The lowest-paid government worker would need 0.1 day's wages to purchase captopril for lowest-priced generics from private sector, while 6.6 days' wages for losartan. For originator brands, the costs rise to 1.2 days' wages for salbutamol inhaler and 15.6 days' wages for omeprazole. CONCLUSIONS: The prices, availability and affordability of medicines in China should be improved to ensure equitable access to basic medical treatments, especially for
