    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.

    Based on the analysis of the basic characteristics for the gob site in Northern Shaanxi Province and the room and pillar mining way about coal mine, the variety rule of the coal beds below the site was studied by the using of FEM during the process of coal mining. The statuses of the stresses and strains and the varieties of the plastic area were simulated in the whole rock and coal pillars. The characters of stresses and deformation of the gob area of the coalmine were analyzed and evaluated after the site built in weathering. Moreover, the long-term stability of the gob area was predicted. As a result, the deformation of the gob area under the site is not been finished, and there is the danger that the gob site will collapsing as a whole; therefore,relative measures must be taken.

    To combat desertification, the Chinese government has launched a series of Desertification Controlling Projects and Policies over the past several decades. However, the effect of these projects and policies remains controversial due to a lack of suitable methods and data to assess them. In this paper, the authors selected the farmingpastoral region of the northern Shaanxi Province in China as a sample region and attempted to assess the effect of Desertification Controlling Projects and Policies launched after 2000 by combining remote sensing and farmer investigation data. The results showed that the combination of these two complementary assessments can provide comprehensive information to support decision-making. According to the remote sensing and Net Primary Production data, the research region experienced an obvious desertification reversion between 2000 and 2010, and approximately 70% of this reversion can be explained by Desertification Controlling Projects and Policies. Farmer investigation data also indicated that these projects and policies were the dominating factor contributing to desertification reversion, and approximately 70% of investigated farmers agreed with this conclusion. However, low supervision and subsidy levels were issues that limited the policy effect. Therefore, it is necessary for the government to enhance supervision, raise subsidy levels, and develop environmental protection regulations to encourage more farmers to participate in desertification control.

  15. Desertification Risk Monitoring for North Shaanxi Province, China, Using Normalized Difference Vegetation Index (NDVI)

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    In this study, the remote sensing is applied to the examination of the relationship between desertification and normalized difference vegetation index (NDVI) in the context of northern Shaanxi Province. This relationship is also examined using spatial analysis methods. A strong negative correlation is found in the largest area desert, indicating that the relationship between desert and NDVI is not a simple linear one and that the correlation coefficient between NDVI and vegetation abundance is significant.The normalized difference vegetation index (NDVI) was compared with other vegetation index-based methodologies. NDVI is a valuable first-cut indicator for such systems, although the analysis and interpretation of its relationship to desertification are complex and also based on the detailed analysis of its reiationship to ecological zone, vegetation type and season. Conclusions thus made would help to upgrade the methodology as an effective tool for early-warning desertification in the northern Shaanxi Province where a drought is a recurring threat. This methodology includes the integration of NDVI with other socio-economic and bio-physical indicators in GIS, the complementation of desert area data with satellite data, and the analysis of the relationship between NDVI and specific climatic zones, for each season and vegetation type.

    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.

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    The soil moisture in Shaanxi Province,a region with complex topography,is simulated using the distributed hydrological model Soil Water Assessment Tool(SWAT).Comparison and contrast of modeled and observed soil moisture show that the SWAT model can reasonably simulate the long-term trend in soil moisture and the spatiotemporal variability of soil moisture in the region.Comparisons to NCEP/NCAR and ERA40 reanalysis of soil moisture show that the trend of variability in soil moisture simulated by SWAT is more consistent with the observed.SWAT model results suggested that high soil moisture in surface soil layers appears in the southern Shaanxi with high vegetation cover,and the Qinling mountainous region with frequent orographic precipitation.In deeper soil layers,high soil moisture appears in the river basins and plains.The regional soil moisture showed a generally decreasing trend on all soil layers from 1951 to 2004,with a stronger and significant decreasing trend in deeper soil layers,especially in the northern parts of the province.

  18. Study of Sand Dunes and Their Effect on Desertification of Cultivated Lands in Shaanxi Province, China Using Remote Sensing Techniques

    2002-01-01

    About half of the arid and semi-arid lands in the world are deserts that comprise various types of aeolian sand dunes deposits. In Shaanxi Province, aeolian sand dunes cover considerable areas of the Yulin desert and northern Jinbian. Sand dunes are moving in the main wind direction and converting some agricultural area to wasteland. Remote sensing of sand dunes helps in the understanding of aeolian process and desertification. Remote sensing data combined with field studies are valuable in studying sand dunes, regional aeolian depositional history. In particular, active and inactive sand dunes of the north Shaanxi Province were studied using remote sensing and geographic information system. In this study, we describe the Landsat thematic mapper (TM) images, covering north Shaanxi Province, which were used to study the distribution, shape, size, trends, density and movement of sand dunes and their effect on desertification of cultivated lands. Estimation was made depending on soil erodibility factor (Ⅰ) and local climatic factor (C) during the period (June to September). The result indicates that soil erosion caused sand drift of 8.957 5, 7.03 ton for Yulin and Jinbian, respectively. The mean sand dunes movement rate were 4.37, 3.11 m, whereas, monthly sand dune advance rate were 1.092 5, 0.777 5 m, for the two locations, respectively. The study reveals that cultivated lands extended obliquely to the direction of sand dune movement are extremely affected, while other segments that extend parallel to the direction of the movement are not affected. Accordingly the north Shaanxi Province was divided into areas of different classes of potential risk. Moreover, blown sands and sand movement from neighboring highlands also affect the area of western desert.

    Objective: It has been recommended that age-related centile curves of anthropometric indexes(such as height, weight) be used rountinly to evaluate the growth and development statues in children. Presented here is the age-related height centile curves for children aged 0-18 years in Shaanxi, China,1995. Methods: Data of the Shaanxi population were retrieved from The Third Nationwide Growth Survey to construct the age-related height centile curves. The LMS method was used for curve fitting; all analyses were carried out on the basis of different sexes through a special program for LMS(λ-median-coefficient) method which was devised by Cole TJ. Results: Centile curves for boys and girls, showing similar age-related features but girls' puberty coming two years earlier than boys'. The period of puberty growth increment was about 2 years longer for boys. At age 18, boys were taller than girls for about 14 cm. Compared with height standard of NCHS(national center of health statistics), Shaanxi children were taller than American children before 14 years for boys, 12 years for girls, but after 15 years for boys and 13 years for girls, Shaanxi children were shorter than American ones. At age 18, Shaanxi children was 5.6 cm for boys and 4.9 cm for girls shorter than NCHS. Shaanxi children's height increase range from 1958 to 1995 at the same age was 4.9-15.1 cm ,with the mean of 9.59 cm for boys, and 3.7-12.5 cm, with the mean of 8.38 cm for girls. Between 1958-1995, the increasing velocity every ten years were 2.57 cm for boys and 2.26 cm for girls, which indicated that the children have reached the optimum. Conclusion: By means of LMS method, we constructed age-related height centile curves for Shaanxi children aged 0-18 years, these height centile curves are the first one for the Chinese children. It can be used as a reference for assessing growth and development status of Shaanxi children aged 0-18 years.

    In order to evaluate the effect of exploiting shallowly buried coal on the ground water and surface water in Shennan Mining Area of northern Shaanxi, we studied the water-resisting degrees of the key aquifuges in overlying soil strata under mining influence. Based on the geologic investigation in Shennan Mining Area, the results of water pressure tests, and the permeability coefficient of clays in Lishi and Bode Ground which are determined by medium-pressured triaxial servo with the process of clay loading and unloading, we proposed the effect of shallowly buried coal mining on the permeability coefficient of the clays. The results show that the shallowly buried coal mining results in thin bedrock roof falling completely, and the destabilization of clay strata results in a change of permeability coefficient of the clays with several orders in the connected fissures area. However, in the pull-apart area, the ground fissures make the permeability coefficient of clay in Lishi Ground largen. With the increase of pressure, the permeability coefficient of clay in Bode Ground becomes smaller, resulting in plastic deformation of the clay, giving a basis for calculating the phreatic level which determinates the possibility of water preserving for exploiting the shallowly buried coal seams.%为评价陕北神南矿区浅埋煤层开采对地下水及地表水的影响,对煤层上覆关键隔水土层的采动隔水性进行研究.在进行了神南矿区野外地质调查的基础上,采用中压三轴伺服仪测定神南矿区离石组黄土及保德组红土在三轴加载及卸载过程中的渗透系数,并结合采前、采后现场压水试验成果研究了浅埋煤层开采前后关键隔水黏土层渗透系数变化特征.试验结果表明:浅埋煤层开采引起薄层基岩整体切落,在贯通裂隙发育区上覆隔水土层失稳表现为渗透系数几个数量级的巨大增加;而在拉张区黏土层上部的离石黄土受地面裂缝影响渗透性

    By using 1998-2010 SPOT-VGT NDVI images, this paper analyzed the spatiotemporal variation of vegetation in northern Shaanxi. In 1998-2010, the NDVI in northern Shaanxi had an obvious seasonal variation. The average monthly NDVI was the minimum (0.14) in January and the maximum (0.46) in August, with a mean value of 0.28. The average annual NDVI presented an overall increasing trend, indicating that the vegetation in this area was in restoring. Spatially, the restoration of vegetation in this area was concentrated in central south part, and the degradation mainly occurred in the north of the Great Wall. Air temperature and precipitation were the important climate factors affecting the variation of vegetation, with the linear correlation coefficients to NDVI being 0.72 and 0.58, respectively. The regions with better restored vegetation were mainly on the slopes of 15 degrees-25 degrees, indicating that the Program of Conversion of Cropland to Forestland and Grassland had a favorable effect in the vegetation restoration in northern Shaanxi.

    Anthrax is an acute zoonotic infectious disease caused by the bacterium known as Bacillus anthracis. From 26 July to 8 August 2015, an outbreak with 20 suspected cutaneous anthrax cases was reported in Ganquan County, Shaanxi province in China. The genetic source tracking analysis of the anthrax outbreak was performed by molecular epidemiological methods in this study. Three molecular typing methods, namely canonical single nucleotide polymorphisms (canSNP), multiple-locus variable-number tandem repeat analysis (MLVA), and single nucleotide repeat (SNR) analysis, were used to investigate the possible source of transmission and identify the genetic relationship among the strains isolated from human cases and diseased animals during the outbreak. Five strains isolated from diseased mules were clustered together with patients' isolates using canSNP typing and MLVA. The causative B. anthracis lineages in this outbreak belonged to the A.Br.001/002 canSNP subgroup and the MLVA15-31 genotype (the 31 genotype in MLVA15 scheme). Because nine isolates from another four provinces in China were clustered together with outbreak-related strains by the canSNP (A.Br.001/002 subgroup) and MLVA15 method (MLVA15-31 genotype), still another SNR analysis (CL10, CL12, CL33, and CL35) was used to source track the outbreak, and the results suggesting that these patients in the anthrax outbreak were probably infected by the same pathogen clone. It was deduced that the anthrax outbreak occurred in Shaanxi province, China in 2015 was a local occurrence.

    Extreme climate index is one of the useful tools to monitor and detect climate change. The primary objective of this study is to provide a more comprehensively the changes in extreme precipitation between the periods of 1954-1983 and 1984-2013 in Shaanxi province under climate change, which will hopefully provide a scientific understanding of the precipitation-related natural hazards such as flood and drought. Daily precipitation from 34 surface meteorological stations were used to calculated 13 extreme precipitation indices (EPIs) generated by the joint World Meteorological Organization Commission for Climatology (CCI)/World Climate Research Programme (WCRP) project on Climate Variability and Predictability (CLIVAR) expect Team on climate change Detection, Monitoring and Indices (ETCCDMI). Two periods including 1954-1983 and 1984-2013 were selected and five types of precipitation days (R10mm-R100mm) were defined, to provide more evidences of climate change impacts on the extreme precipitation events, and specially, to investigate the changes in different types of precipitation days. The EPIs were generated using RClimRex software, and the trends were analyzed using Mann-Kendall nonparametric test and Sen's slope estimator. The relationships between the EPIs and the impacts of climate anomalies on typical EPIs were investigated using correlation and composite analysis. The mainly results include: 1) Thirteen EPIs, except consecutive dry day (CDD), were positive trends dominated for the period of 1984-2013, but the trends were not obvious for the period of 1954-1983. Most of the trends were not statistically significant at 5 % significance level. 2) The spatial distributions of stations that exhibited positive and negative trends were scattered. However, the stations that had negative trends mainly distributed in the north of Shaanxi province, and the stations that had positive trends mainly located in the south. 3) The percentage of stations that had positive

    The biodiversity and biogeography of rhizobia associated with bean in Shaanxi Province were investigated. A total of 194 bacterial isolates from bean nodules collected from 13 sampling sites were characterized based on phylogenetic analyses of the 16S rRNA gene, the housekeeping genes recA, glnII and atpD, and the symbiotic genes nodC and nifH. Fifteen genospecies belonging to the genera Rhizobium, Agrobacterium, Ensifer, Bradyrhizobium and Ochrobactrum were defined among the isolates, with Rhizobium sp. II, Agrobacterium sp. II, E. fredii and R. phaseoli being the dominant groups. Four symbiotic gene lineages corresponding to Rhizobium sp. I, Rhizobium sp. II, R. phaseoli and B. liaoningense were detected in the nodC and nifH sequence analyses, indicating different origins for the symbiotic genes and their co-evolution with the chromosome of the bacteria. Moreover, the Ensifer isolates harbored symbiotic genes closely related to bean-nodulating Pararhizobium giardinii, indicating possible lateral gene transfer from Rhizobium to Ensifer. Correlation of rhizobial community composition with moisture, temperature, intercropping, soil features and nutrients were detected. All the results demonstrated a great diversity of bean rhizobia in Shaanxi that might be due to the adaptable evolution of the bean-nodulating rhizobia subjected to the diverse ecological conditions in the area.

    China is characterized by a low fertility intention, a strong preference for sons, as well as a stringent birth control policy. In this study, we used data from a Fertility Intention and Behavior Survey of 2101 questionnaires conducted in 2013 in Shaanxi Province of northwestern China, and event history analysis methods to examine the effect of fertility intention and preference for sons on the probability of having a second child. The results not only validate the correlation of fertility intention with having a second child empirically, even in the low fertility intention and stringent birth control context of China, but also show that women with a preference for sons were less likely to have a second child. Women with son preference turn to sex-selective abortion to ensure that their first child is a son, thus reducing the likelihood of a second child and decreasing the fertility rate. Our findings also shed light on China's potential fertility policy adjustment.

    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.

    A survey of dairy goats for infection with Eimeria species of coccidia was conducted in the Shaanxi province, northwestern China between December and November 2010, including Saanen and Guanzhong breeds. A total of 584 fecal samples (250 and 334 from Saanen and Guanzhong dairy goats, respectively) in six farms were collected. Eimeria oocysts were seen in 568 (97.3%) fecal samples, with six species, namely Eimeria jolchijevi, Eimeria arloingi, Eimeria alijevi, Eimeria caprina, Eimeria hirci, and Eimeria christenseni. The most prevalent were E. arloingi in Saanen and Guanzhong dairy goats, with an overall prevalence of 83.3% and 84.4%, and the lowest prevalence were E. christenseni (26.9%) and E. hirci (20.7%) for Saanen and Guanzhong Dairy goats, respectively. Two or more Eimeria species were commonly presented in all the age groups; 80.0% and 81.4% of positive Saanen and Guanzhong dairy goats carried more than two species, and 1.6% and 6.5% of two breeds had six species. The results of the present survey suggested that Eimeria infection is wide and severe in the Saanen and Guanzhong dairy goats, which suggested that integrated strategies should be implemented to prevent and control coccidial infection in dairy goats in this province.

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A discovery of daughter minerals in fluid inclusions of Taibai gold deposit, Shaanxi province has been focused on, which is a unique breccia-cemented gold-bearing system. The breccia zone strikes NWW-SEE, occurring in Devonian strata of Southern Qinling Mountains. The cement is mainly composed of ankerite, pyrite, calcite and quartz, which may be divided into four main tectonic-mineralizing stages. Gold mainly occurs in pyrite and ankerite of stage II and IV. It is found that three types of fluid inclusions can be distinguished: (1) aqueous inclusions (type B); (2) CO2-rich inclusions (type C); (3) daughter minerals-containing inclusions (type A). LRM (Laser Raman Micro-probe) analyses shows that the content of CO2 occupies 54.4-70.7% (mole fraction, so as the follows) in vapor phases of different type fluid inclusions. CH4 (5.2%-7.3%) and H2S (6.0%-12.7%) exist in both vapor and liquid phases. Many daughter minerals in fluid inclusions of ankerite and quartz have been found. Several kinds of daughter minerals, including ankerite, pyrite, arsenopyrite and halite, were determined by using SEM (scanning electron microscope) / EDS (energy dispersive spectrometer) technique. EPMA (electron probe micro-analysis) technique was also applied to study the daughter minerals exposed to the surface of polis hed thin sections.

    Full Text Available Anemia is one of the most prevalent public health problems among infants and iron deficiency anemia has been related to many adverse consequences. The overall goal of this study is to examine the prevalence of anemia among infants in poor rural China and to identify correlates of anemia. In April 2013, we randomly sampled 948 infants aged 6–11 months living in 351 villages across 174 townships in nationally-designated poverty counties in rural areas of southern Shaanxi Province, China. Infants were administered a finger prick blood test for hemoglobin (Hb. Anthropometric measurement and household survey of demographic characteristics and feeding practices were conducted in the survey. We found that 54.3% of 6–11 month old infants in poor rural China are anemic, and 24.3% of sample infants suffer from moderate or severe anemia. We find that children still breastfed over 6 months of age had lower Hb concentrations and higher anemia prevalence than their non-breastfeeding counterparts (p < 0.01, and that children who had ever been formula-fed had significantly higher Hb concentrations and lower anemia prevalence than their non-formula-fed counterparts (p < 0.01. The results suggest the importance of iron supplementation or home fortification while breastfeeding.

    Full Text Available Excessive socioeconomic activities in the Weihe River region have caused severe ecosystem degradation, and the call for the recovery and maintenance of the river health has drawn great attention. Based on the connotation of river health, previous research findings, and status quo of the Weihe River ecosystem, in this study, we developed a novel health evaluation index system to quantitatively determine the health of the Weihe River in Shaanxi Province. The river in the study area was divided into five reaches based on the five hydrological gauging stations, and appropriate evaluation indices for each river section were selected according to the ecological environmental functions of that section. A hybrid approach integrating analytic hierarchy process (AHP and a fuzzy synthetic evaluation method was applied to measure the river health. The results show that Linjiancun-Weijiabao reach and Weijiabao-Xianyang reach are in the “moderate” level of health and Lintong-Huaxian reach and downstream of Huaxian reach are in the “poor” health rating, whereas Xianyang-Lintong reach is in the “sick” rating. Moreover, the most sensitive factors were determined, respectively, for each reach from upper stream to lower stream in the study area.

    Satellite image data and thematic map data were used to provide comprehensive views of surface-bound conditions such as soil and vegetation degradation. The current work applies a computerized parametric methodology, developed by FAO, UNEP and UNESCO to assess and evaluate soil degradation at 1: 250 000 mapping scale. The study area is located in the arid and semi-arid zone of the northern part of Shaanxi Province in China, a region with considerable agricultural potential; Landsat TM images were utilized to provide recent data on land cover and use of the area. ARC/INFO and ArcView softwares were used to manage and manipulate thematic data, to process satellite images, and tabular data source. ER mapper software is utilized to derive the normalized difference vegetation index (ND VI) values while field data to estimate soil erodibility (SE) factor. A system is established for rating soil parameters, slope, climate factor and human factor activity. The rating values serve as inputs into a modified universal soil loss equation (USLE) to calculate the present state and risk for soil degradation processes, namely soil wind erosion. The produced maps and tabular data show the risk and the present status of different soil degradation processes. The study area, in general, is exposed to high risk of wind erosion and high hazards of water erosion. Several desertification maps were produced, which reflect the desertification types persisting in the study area. Wind erosion, water erosion, vegetation degradation,physical degradation and sulinization are the basic desertification maps, and others are combinations of these basic maps. In terms of statistic analysis, 33. 75 % of the total land area (120. 330 0 ha) is considered as sand or sand dune, and not included in our analysis of desertification. About 29. 41% of the total land area has slight or moderate desertification and 37. 465 % is facing severe desertification.

    In arid and semi-arid regions, a close relationship exists between groundwater and supergene eco-environmental issues such as swampiness, soil salinization, desertification, vegetation degradation, reduction of stream base flow, and disappearance of lakes and wetlands. When the maximum allowable withdrawal of groundwater (AWG) is assessed, an ecology-oriented regional groundwater resource assessment (RGRA) method should be used. In this study, a hierarchical assessment index system of the supergene eco-environment was established based on field survey data and analysis of the supergene eco-environment factors influenced by groundwater in the Tuwei River watershed, Shaanxi Province, China. The assessment system comprised 11 indices, including geomorphological type, lithology and structure of the vadose zone, depth of the water table (DWT), total dissolved solids content of groundwater, etc. Weights for all indices were calculated using an analytical hierarchy process. Then, the current eco-environmental conditions were assessed using fuzzy comprehensive evaluation (FCE). Under the imposed constraints, and using both the assessment results on the current eco-environment situation and the ecological constraint of DWT (1.5-5.0 m), the maximum AWG (0.408 × 108 m3/a or 24.29 % of the river base flow) was determined. This was achieved by combining the groundwater resource assessment with the supergene eco-environmental assessment based on FCE. If the maximum AWG is exceeded in a watershed, the eco-environment will gradually deteriorate and produce negative environmental effects. The ecology-oriented maximum AWG can be determined by the ecology-oriented RGRA method, and thus sustainable groundwater use in similar watersheds in other arid and semi-arid regions can be achieved.

    Triplet surveys were conducted in the city of Xi' an and two villages (one in the vicinity and the other at a distance) in Shaanxi Province in China in October-November (when agricultural activitis were low), 1997, to elucidate nutrient intakes with a focus on possible urban-rural differences. Total food duplicate samples were collected from non-smoking and non-habitually drinking adult healthy women (about 50 subjects per site and 149 in total). The nutrient intakes were estimated from the weight of food items in reference to national food composition tables. On average, the women took 1873 kcal energy, 54 g protein and 37 g lipid per day, with a lipid energy ratio of18.4%. Both excess and insufficient energy intake was observed as a result of food intake analysis and body mass index determination. With regard to minor nutrient intakes, insufficiency was serious in the case of calcium, vitamin A and vitamin B2, but not with iron. Whereas dependency on plant foods for sources of energy and protein was common to the three regions, Xi' an people consumed more animal foods than those in the villages. Intake of fish and shellfish was quite low throughout the three regions. Among the four types of cereals, wheat was consumed most substantially in the three regions and in three meals (except for the village where people essentially did not take lunch in reflection of low agricultural activities), whereas rice was consumed more in Xi' an than in the two villages. Maize consumption was higher in the two villages (especially for breakfast) than in the city.In contrast, foxtail millet (although in small amounts) was taken primarily in Xi'an and only at the time of breakfast.

In this study, the concentrations and distributions of urinary arsenic metabolites in 57 volunteers (36 subjects with skin lesions and 21 subjects without skin lesions, who had been exposed to elevated levels of arsenic present in coal in Changshapu village in the south of Shaanxi Province (China, were reported. The urinary arsenic species, including inorganic arsenic (iAs [arsenite (iAsIII and arsenate (iAsV], monomethylarsonic acid (MMAV and dimethylarsinic acid (DMAV, were determined by high-performance liquid chromatography (HPLC combined with inductively coupled plasma mass spectroscopy (ICP-MS. The relative distributions of arsenic species, the primary methylation index (PMI = MMAV/iAs and the secondary methylation index (SMI = DMAV/MMAV were calculated to assess the metabolism of arsenic. Subjects with skin lesions had a higher concentration of urinary arsenic and a lower arsenic methylation capability than subjects without skin lesions. Women had a significantly higher methylation capability of arsenic than men, as defined by a higher percent DMAV and SMI in urine among women, which was the one possible interpretation of women with a higher concentration of urinary arsenic but lower susceptibility to skin lesions. The findings suggested that not only the dose of arsenic exposure but also the arsenic methylation capability have an impact on the individual susceptibility to skin lesions induced by coal arsenic exposure.

  8. Ore fluid geochemistry of the Jinlongshan Carlin type gold ore belt in Shaanxi Province, China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The Jinlongshan gold ore belt in southern Shaanxi Province contains a number of Carlin-type gold deposits in the Qinling collisional orogenic belt. Their fluid inclusions are of the Na+ - Cl- type. From the main metallogenic stage to later stages, the total quantity of anions and cations, temperature and deoxidation parameter (R) for fluid inclusions all gradu ally decreased, suggesting the gradual intensification of fluid oxidation, the reduction of met allogenic depth and the input of meteoric water and organic components. The deposits were formed during crustal uplifting and hence had similar tectonic settings to orogenic gold depos its. The CO2 contents and CO2/H2O values of the ore fluid increased from early to late sta ges, and the wall-rock alteration is represented by decarbonation, which is inconsistent with the characteristics of orogenic gold deposits. It is also discovered that Na + , K + ,SO42-, Cl-and the total amounts of anions and cations in the inclusions in quartz are higher than those in the coexisting calcite. The H, O and C isotope ratios indicate that the ore fluid was sourced from meteoric water and metamorphic devolatilisation of the sedimentary rocks that host the ores. The high background δ18O and δ13C values of wall rocks resulted in high δ18O and δ13 C values of ore fluid and also high δ 18 O and δ 13 C values of hydrothermal minerals such as quartz and carbonate. The carbon in ore fluid stemmed largely from the hosting strata. The δ 18O and δ13C values of Fe-calcite and the δD values of fluid inclusions are lower than those of calcite and quartz. In terms of the theory of coordination chemistry, all these differences can be ascribed to water-rock interaction in the same fluid system, instead, to the multi source of ore fluid.

This was achieved by combining the groundwater resource assessment with the supergene eco-environmental assessment based on FCE. If the maximum AWG is exceeded in a watershed, the eco-environment will gradually deteriorate and produce negative environmental effects. The ecology-oriented maximum AWG can be determined by the ecology-oriented RGRA method, and thus sustainable groundwater use in similar watersheds in other arid and semi-arid regions can be achieved.

    Full Text Available OBJECTIVES: 1 To understand the current prevalence and main types of birth defects, 2 assess the periconceptional exposure of factors associated with birth defects in Shaanxi Province, and 3 provide scientific evidence for local governments to formulate services for the primary prevention of birth defects. METHODS: We sampled 16,541 households from 128 townships in 16 counties/districts in Shaanxi province using a multi-stage random sampling method. Among them, 10,544 women who had live born or stillborn infants with gestational age ≥ 28 weeks between 2008 and 2009 were interviewed using a structured questionnaire designed to collect information about periconceptional risk factor exposure, health care service utilization, and micronutrient supplements. Logistic regression was performed to assess the risk factors associated with birth defects and adjustments were made for imbalanced social-demographic characteristics between case and control groups. RESULTS: The prevalence of congenital birth defect in Shaanxi province was 14.3/1000 births. The environment risk factors associated with birth defects include unhealthy lifestyle (Alcohol, odds ratio (OR: 3.60, 95% confidence interval (CI 1.64-7.91; Smoking, OR: 1.32, 95% CI: 0.99-1.75; Drink strong tea, OR: 1.81, 95% CI: 1.27-2.59, exposure to heavy pollution (OR: 1.53, 95% CI: 1.01-2.30, maternal diseases (OR: 1.77, 95% CI: 1.35-2.33, drug use (OR: 2.11, 95% CI: 1.51-2.95, maternal chemical pesticide exposure (OR: 2.30, 95% CI: 1.16-4.57, and adverse pregnancy history (OR: 10.10, 95% CI: 7.55-13.53. Periconceptional folic acid or multiple micronutrients including folic acid supplementation, was associated with a reduced rate of birth defects (OR: 0.54, 95% CI: 0.29-0.998. CONCLUSIONS: Health care service utilization, unhealthy lifestyle factors, and environment risk factors seem to be associated with birth defects in Shaanxi province. Governmental agencies should focus on effective primary

    The regional policy in China is shifting from solely gross domestic product (GDP) orientation to development that is more balanced between economic growth and ecological protection, as well as achieving equality among regions. Using land use maps and the adjusted value coefficients to assess ecosystem service values (ESV) for the 1980s, 1995, 2000, and 2010, we estimated the ESV in Shaanxi Province for different years, and characterized the spatial and temporal distribution of ESV and GDP. The results demonstrated that the total value of ecosystem services in Shaanxi Province increased from 208.95 billion Yuan in the 1980s to 309.76 billion Yuan in 2010. Variation Coefficient (Cv) and Theil index (T) were used to reflect the disparities of GDP or ESV within the study area. The values of Cv in descending order are GDP, ESV per capita, ESV, and GDP per capita. The Theil indexes of GDP were much greater than the ones of ESV. Variations of Cv and T showed that disparity in GDP kept increasing from the 1980s to 2000, then decreased; while no significant change in regional disparity of ESV were detected in parallel. The cities with higher GDP usually contributed little to ESV, and vice versa. The variation in GDP and ESV, in terms of the prefectural totals and per capita values, increased from the 1980s to 2010. This study provides an accessible way for local decision makers to evaluate the regional balance between economic growth and ecosystem services.

    To select appropriate native species in Northern Shaanxi for phytoremediation, the growth index of six kinds of leguminous plants planted in petroleum contaminated soils were investigated through pot culture. Petroleum concentrations were set at 0, 5 000, 10 000, 20 000, 40 000 mg x kg(-1) respectively with three replicates. Using different levels of seed germination rate, germination time, individual height, wilting rate, dry weight and chlorophyll content in leaves of tested plants as the ecological indicator. The results showed that tested plants have significantly different responses to petroleum pollution. Compared with those planted in clean soils, seed germination rate and individual height were promoted when petroleum concentration was lower than 5000 mg x kg(-1), but inhibition occurred when petroleum concentrations were higher than 10000 mg x kg(-1). Strong endurance of Medicago sativa was observed to petroleum polluted soil, especially at lower petroleum concentration. Leaf wilting of Robinia pseudoacacia was unobserved even when petroleum concentration was 40 000 mg x kg(-1), thus displaying the potential of remediating petroleum contaminated soils. The petroleum concentration was significantly and negatively correlated with seed germination rate, individual height and dry weight, but positively correlated with chlorophyll content in leaves.

    There exists abundant thermal water recourses in Guanzhong basin, Shaanxi province (northwestern China).With the deepening of exploitation for thermal aquifer nowadays, the information about the origin and movement of thermal water is limited by using traditional methods. This paper applies environmental isotope techniques to offer direct constraints on the recharge and movement of thermal water and improve the geological and hydrogeological database in Guanzhong Basin. The research on the environmental isotopes shows that the geothermal water of the area is mainly recharged by meteoric water. The temperature of meteoric water which replenishes geothermal water in the study area is -16℃. The estimated age of recharging the geothermal water is 13.3-28.2 ka based on the isotope analysis, belonging to the last glacial period in Late Quaternary. The source of replenishment of the geothermal water is thought to have been derived from glacial snow-melt water with an elevation higher than 1 500 m (ASL) in the north side of Qinling Mountain. The isotopic analysis denotes that the geothermal water in the southern Guanzhong basin is the mixture of net thermal water and normal temperature groundwater. Based on calculating the percentage of the mixture, nearly half of cold groundwater had participated the circulating of the geothermal water. However, in the center part of the basin, some artificial factors such as mismanage of pumping are probably the reason for the mixturing. The temperature range of the geothermal reservoirs in the basin is estimated at about 80-121℃ based on calculation of both SiO2 geothermometer and thermal water saturation index, which are basically in accordance with the measured temperature of thermal water. Based on the replenishment time and mixture extent with cold water, the thermal water in the studied area can be classified into three parts: mixed thermal water replenished by modern meteoric water; mixed thermal water replenished by both

    Abstract Socioeconomic disparities in birth weights (BWs) are associated with lifelong differences in health and productivity. Understanding socioeconomic disparities in BW is presently of concern to develop public health interventions that promote a good start in life in Northwest China. In the study, our objective is to investigate the socioeconomic disparities in low and high BW from 2010 to 2013 in this region. Those single live births were recruited using a stratified multistage sampling method in Shaanxi province from August to December 2013. Data were collected with a structured questionnaire and a review of birth certificates. Socioeconomic status (SES) was stratified based on the calculated household wealth index. Prevalence differences (PDs) and concentration indices (CIs) were used to depict the SES inequality of low BW (LBW) and macrosomia. Information for 28722 single live births born were obtained in Shaanxi province. From 2010 to 2013, the overall rates of LBW decreased, and the difference in LBW across differing SES groups decreased by 0.7% (boys, 0.4%; girls, 0.8%). From 2010 to 2013, the overall rates of macrosomia increased by 14.3% (boys, 17.5%; girls, 7.8%), whereas the PDs in macrosomia across various SES groups remained unchanged. From 2010 to 2013, concentration indices for SES inequalities in LBW and macrosomia confirmed the results shown by differences in prevalence. Compared with mothers of high SES, those in low SES group were significantly older, less educated, engaged in farming with less availabile healthcare, and engaged in unhealthy lifestyles (eg, exposure to secondhand smoke) during pregnancy, regardless of the baby's sex. From 2010 to 2013, in Shaanxi province, the negative association between socioeconomic status and LBW weakened. Rates of macrosomia were higher in those of high SES, but the SES disparities varied insignificantly over the same time. Our findings may provide valuable insights to direct healthcare policies for

    Full Text Available This article examines some of the forms of water management in Shanxi [山西] and Shaanxi [陕西] provinces during the Ming and Qing dynasties. Facing serious water shortages and shrinking state power for water management, the local society in Shanxi and Shaanxi took over water management and gradually formed a local self-government system for the water resources. Depending on water management organizations in which the local gentry were the core power, the water rules were based on natural topographic conditions, historical water practices in the locality, traditional moral-ethical ideas, and even water policies and water laws. This water management system played a positive role in mobilizing the participation of members, preventing opportunistic behavior such as free riding and rent seeking, while decreasing the probability of water conflicts and the costs of litigation. However, this water management system was also subject to endemic corruption because of the lack of effective monitoring from the local government. As similar problems appear to exist in China today, this article analyzes the features of this water management system, and examines the problems that faced those systems so as to provide a warning from history for modern society.

    Soil moisture is the primary factor limiting plant growth and vegetation rehabilitation in the loess region of northern Shaanxi, China. This 5-year (2008-2012) study investigated methods of selecting appropriate microsites for vegetation restoration based on efficient use of soil moisture; 5-year data were compared with 56 years of precipitation data using standardized precipitation index. In addition, the effects of microtopography on the spatiotemporal variations of soil moisture were analyzed at the Wuqi Ecological Station of Beijing Forestry University. Results showed that average annual precipitation during last 5 years fell by 12.4% during the growing season compared with 1957-2012 data and soil moisture content at depth of 0-160 cm under went dramatic changes and became relatively low in July and August. Soil moisture content varied in different microtopographical units as follows: gullies > gently-sloped terraces > collapsed soils > undisturbed slopes (control) > furrows > escarpments. The vertical distribution of soil moisture content in different microtopographical units showed dramatic changes at depth of 0-40 cm. Soil moisture content of gently-sloped terraces, gullies, collapsed areas, furrows, and undisturbed slopes was highest at depth of 80-160 cm with a level of instability at depth of 40-80 cm. For gently-sloped terraces and gullies, soil moisture content followed the order of 40-80 cm > 0-40 cm; for collapsed areas, furrows, and undisturbed slopes, soil moisture content follows the order of 0-40 cm > 40-80 cm. For escarpments, soil moisture content varied with depth in a different pattern: 0-40 cm > 80-160 cm > 40-80 cm. This study is of theoretical significance and will help guide the sustainable development of ecological restoration and vegetation rehabilitation in the Loess region.

    The Tiantaishan phosphorite-Mn carbonate ores occur in the Early Cambrian Tananpo Formation in complexly folded and faulted rocks located in southern Shaanxi Province. About 65 x 106 tonnes of 17% P2O5 ore reserves exist and Mn-ore reserves are about 8.3 x 106 tonnes of +18% Mn. The stratigraphic sequence in ascending order consists of black phyllite, black to gray phosphorite ore, black phyllite, rhodochrostone ore, Mn mixed-carbonates, and dolostone. Data are presented from microprobe mineral chemistry, whole-rock chemistry, stable isotopes of carbonates, X-ray mineralogy, petrographic and SEM observations, and statistical analysis of chemical data. The dominant ore-forming minerals are hydroxy- and carbonate fluorapatite and Ca rhodochrosite, with Mg kutnahorite and dolomite comprising the Mn mixed-carbonate section. Pyrite occurs in all rock types and alabandite (MnS) occurs throughout the rhodochrostone section. The mean P2O5 content of phosphorite is 31% and argillaceous phosphorite is 16%, while the mean MnO content of rhodochrostone ore is 37%. Phosphorite ores are massive, spheroidal, laminated, and banded, while rhodochrostone ores have oolitic, spheroidal, and granular fabrics. The most distinguishing characteristics of the ores are high total organic carbon (TOC) contents (mean 8.4%) in the phosphorite and high P2O5 contents (mean 2.7%) in the rhodochrostone ore. The atypically high TOC contents in the Tiantaishan phosphorite probably result from very strong productivity leading to high sedimentation rates accompanied by weak reworking of sediments; poor utilization of the organic matter by bacteria; and/or partial replacement of bacterial or algal mats by the apatite. The depositional setting of the ores was the margin of an epicontinental seaway created as a direct consequence of global processes that included break-up of a supercontinent, formation of narrow seaways, creation of extensive continental shelves, overturn of stagnant, metal-rich deep

    The effect of different modified tree shapes (MTS) on light reception was compared among three types of apple orchards: small-sized canopy, middle-sized canopy and large-sized canopy in Weibei areas of Shaanxi Province, China, by using WinsCanopy2004a (2002) for Hemispherical Image Analysis. The results showed that higher average values of photosynthetic photon flux density (PPFD) under canopy per day appeared in all tested orchards, and the number of branches per 667 m2 was lower, indicating that the modified tree shapes were effective to improve the light conditions of canopy but the pruning amount seemed to be slightly more than the appropriate level in Weibei areas. The middle-sized canopy had the maximal light penetration and the small-sized canopy had the least and the leaf area index (LAI) and the ratio of one year-old shoots to scaffold limbs were maximal in large-sized canopy orchards.

  2. Factors associated with low cure rate of tuberculosis in remote poor areas of Shaanxi Province, China: a case control study

    Science.gov (United States)

    2010-01-01

    Background The directly observed therapy-short course (DOTS) strategy was introduced in Shaanxi province, China to improve tuberculosis (TB) control by means of improved case detection (target: > = 70%) and treatment success rates (target: > = 85%) in new smear positive (SS+) TB patients. At a provincial level the targets were both reached in 2005. However in 30 (28%) out of 107 counties of Shaanxi province the cure rate was below 85%. This study aimed to investigate patient and treatment characteristics associated with non-cure after tuberculosis (TB) treatment in these counties. Methods In this case-control study, new smear positive TB cases in 30 counties with a cure rate control institutes, missing sputum re-examinations during treatment, and not having a treatment observer. Twenty-six percent of patients did not have a treatment observer. The non-cure rate was better for those with a doctor (odds ratio (OR) 0.38, 95% confidence interval (CI) 0.17-0.88) as treatment observer than for those with a family member (OR 0.62, 95%CI 0.37-1.03). The main reason for interrupted treatment mentioned by patients was presence of adverse effects during treatment (46.5%). Conclusions Interruption of treatment was most strongly associated with non-cure. Although treatment observation by medical staff is preferred, in order to diminish the proportion of patients who do not have a treatment observer and thereby reduce the proportion of patients who interrupt treatment, we suggest making it possible for family members, after sufficient training, to be treatment observers in remote areas where it is logistically difficult to have village doctors observe treatment for all patients.

    There are large deltaic systems in the Triassic Yanchang Formation in the northern Shaanxi area of the Ordos Basin, and developed two sets of good source-reservoir-caprock assemblages and many sets of oil-beating beds. Exploration experience demonstrates that the formation and distribution of the reservoir were controlled by the generative depression of the Yanchang Formation, and deltaic reservoir sand body is the material basis for large-scale oilfields. In addition, secondary laumontite in a low permeable area was dissolved and then a high permeable area was formed. The updip lithologic variety of reservoir sand bodies is favorable to the formation of subtle lithologic traps, and the deltaic reservoirs are characterized by large multi-beds of oil-generation and abundant hydrocarbon resources. In this paper, the petroleum geologic settings of the studied area are analyzed, and the accumulation characteristics and exploration methods of lithologic reservoirs are summarized. It is of theoretical significance for the study of the exploration theories of lithologic reservoirs, and also expedites the exploration steps of deltaic reservoirs in the northern Shaanxi area.

    Full Text Available OBJECTIVE: To evaluate the prices and availability of paediatric essential medicines in Shaanxi Province, China. METHODS: Price and availability data for 28 paediatric essential medicines were collected from 60 public hospitals and 60 retail pharmacies in six areas of Shaanxi Province using a standardised methodology developed by the World Health Organization and Health Action International, during November to December 2012. Affordability was measured as the number of days' wages required for the lowest-paid unskilled government worker to purchase standard treatments for common conditions. Data on medicine price components were collected from hospitals, wholesalers and distributors to obtain price mark-ups. FINDINGS: The mean availabilities of originator brands (OBs and lowest-priced generics (LPGs were 10.8% and 27.3% in the public hospitals and 11.9% and 20.6% in the private pharmacies. The public procurement and retail prices were 2.25 and 2.59 times the international reference prices (IRPs for three OBs, and 0.52 and 0.93 times for 20 LPGs. In the private sector, the final prices for OBs and LPGs were 3.89 and 1.25 times their IRPs. The final price in the private sector was 2.7% lower than in the public sector for OBs, and 14.1% higher for LPGs. Generally, standard treatments cost less than 1 day's wages in both sectors. Distribution mark-ups applied to brand salbutamol in Xi'an was 65.5%, and up to 185.3% for generic. Cumulative mark-ups for LPGs in Ankang were also high, from 33% to 50%. The manufacturer's selling price is the largest contributor to the final price in both areas. CONCLUSIONS: The government should approve a list of national paediatric essential medicines. The availability, price and affordability of these should be improved in both public hospitals and private pharmacies to enable children to obtain effective treatment. Measures should be taken to improve the efficiency of the centralised medicine purchasing system.

    Objective The psychologic health level of college and secondaryschool students and the relevant fac- tors were investigated to scientific basis and guidance for school mental health work. Methods Standard 1251 cases were drawn from 1% of students in colleges and middle schools of Shaanxi province. Taking 14 psychic health level indexes in SCL-90 as dependent variable and 109 indexes of psychic health back ground as in-dependent variable, multi-factor analyses have been made. Results 22.6 % of students had relatively serious psychological problems. The score of SCL-90 in females was a little bit higher than that in males. The scores of students at both universities and se- nior middle schools were higher than that in junior middle schools students. The score of SCL-90 of students who came from the countryside was higher than that of city students. The score of the whole students was higher than that of the normal. The students with psychic problems showed obsession, interpersonal sensitivity, depression, anxiety, paranoia and hostility. Factor-analysis showed that influencing factors included history of positive individual risking behavior, physical conditions,grade,address, family influences, menses and sexual prombles, bad relation with others, poor self-assessment. Conclusion The psychologic health level of the students investigated is lower than that of the whole society. The factors, which hamper psychic health of students, are biological ,psychological and social in nature.

    2000-01-01

    We have collected a suite of Paleoloxodon naumanni-Coelodonta antiquitatis fossils from a river terrace profile between Xi'an and Xianyang cities in Guanzhong Area, Shaanxi Province. A detailed examination of the fossils, together with 14C determinations and pollen analyses, have enabled us to reconstruct preliminary features of climate and environment changes and their evolutionary processes, within the last glacial maximum (LGM): about 20 ka ago, the climate was basically cool and wet, and was favourable for the existence of Paleoloxodon naumanni-Coelodonta antiquitatis fauna. This was followed by a cold, dry phase which was no longer suitable for this type of faunal suite, causing the death of a large number of mammalian assemblages. The available evidence indicates the existence of cold-dry and cool-wet climate and environment fluctuations during the LGM. The cool-wet stage within the LGM reflects a Heinrich event occurring in the high latitude areas, proving the existence of a teleconnection between polar-high latitude areas and the Loess Plateau.

    In this study, we analyzed the epidemiology of measles cases from January 2004 to December 2011 and measles immunity levels among a healthy population from January to June 2012, in Baoji, Shaanxi Province. This study aimed to identify susceptible populations to measles and to establish methods of measles prevention and control. Measles incidence was at the lowest level in 2011 (0.32 per 100,000 populations). Among these patients, the proportion of those younger than 8 months and those older than 27 years of age was relatively high. The overall antibody positive rate was 78.90%, and the average antibody geometric mean concentration was 562.15 mIU/ml. Measles immunity level was high among children aged 8 months to 6 years and low among infants aged 1-7 months. To reduce the incidence of measles among infants younger than 8 months, implementation of measles vaccine (MV) for women of childbearing age is recommended. Measles immunity level was low among some individuals vaccinated with aqueous MV and lyophilized MV. Supplementary immunization will be recommended for freshmen in universities and colleges, where many students are recruited from various parts of China.

    Based on spatial climatic data of agriculture and the experiment data, the models of agro-ecological assessment of climate for agricultural suitability in this study were developed using the fuzzy mathematical method. Three coefficients, in- cluding the resource coefficient (Cr), the efficiency coefficient (Ce), and the utility co- efficient (K), were used in the models, which were calculated based on temperature, moisture, and sunshine duration data of Guanzhong region, Shaanxi Province. The results indicated that resource coefficient was higher in west of the region than that in east, and higher in south (especially in the Central Shaanxi Plain) than that in the Weibei plateau. The value of Cr changed from 6.5 to 9.2 from north to plain area. Spatial change of efficiency coefficient was obvious, lower in the northeast than in the central plain, and the value of Ce changed from 2.3 to 6.5 from the northeast to the central plain. As for utility coefficient, it was lower in northeastern part of the Weibei plateau and in southern mountain areas than that in the central plain, showing significant latitudinal zonality. Furthermore, the value of K increased from 0.35 to 0.78 from northeast to the central plain, and decreased from 0.78 to 0.53 from the central plain to southern mountain areas. These indicated that climate resource in the central plain region was more abundant and potential, compared with other regions. GuanZhong region was classified into three larger agricultural zones and three small independent zones, according to agro-ecological assessment. Light, heat and water resources should be made use of in an efficient way in spatial allo- cation of agricultural production. For example, water facilities should also be im- proved in Weibei plateau region where highly-qualified fruit should be enhanced and fruit processing industrial chain should be shaped. Large-scale production area of wheat should be increased in central irrigation region and more vegetable

    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 is 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.%通过对陕西省农村居民收入差距现状分析发现,陕西省农村居民收入不仅低于全国平均收入水平,更远远低于发达地区农村居民收入水平和城镇居民收入水平,在低收入的背后是各收入组、各地区间农村居民收入差距拉大的事实.在此基础上,从文化差异、地区经济差异和产业结构差异3个方面阐述了陕西省农村居明收入差距产生的原因,并提出了缩小收入差距,增加陕西农民收入的对策.

    火电机组的NOx治理,是继火电厂开展脱硫工作后落实科学发展观、改善大气环境质量的又一重大举措,是构建和谐社会、实现人民群众根本利益的内在要求。“十二五”期间,燃煤火电仍将是陕西省的主要能源利用形式,因此防治NOx污染的任务十分艰巨。目前,陕西省已有4家火电企业进行了脱硝设施的建设。由于脱硝设施的建设与运营费用全部由企业自行负担,经营压力增大。通过对陕西省已建脱硝设施电厂的建设与运营情况进行分析,研究脱硝电价政策出台的必要性和紧迫性,并就陕西省脱硝电价政策提出具体、可操作的建议。%NOx control of thermal power is another major initiative to implement the scientific concept of development and improve air quality after power plant desulfurization work, and it is also the inherent requirements of building a harmonious society and realizing the people's fundamental interests. During the National Twelfth Five-Year Plan period (2011-2015), coal-fired thermal power will remain the main energy form of Shaanxi Province, so the task of NO~ pollution prevention and control is very arduous. Up to now, four thermal power enterprises have built denitrification facilities in Shaanxi Province. Due to the fact that the thermal power enterprises solely bear the cost for construction and operation of denitrification facilities, their operating pressures have increased. Based on an analysis of the operating situations of the thermal power plants with denitrification facilities in Shaanxi Province, this paper studies the necessity and urgency for formulating the denitrification price policy and some specific and actionable recommendations are proposed for Shaanxi Province to formulate the denitrification price policy.

    Full Text Available In this study, statistical data on the national economic and social development, including the year-end actual area of arable land, the crop yield per unit area and 10 factors, were obtained for the period between 1980 and 2010 and used to analyze the factors driving changes in the arable land of the Loess Plateau in northern Shaanxi, China. The following areas of arable land, which represent different spatial scales, were investigated: the Baota District, the city of Yan’an, and the Northern Shaanxi region. The scale effects of the factors driving the changes to the arable land were analyzed using a canonical correlation analysis and a principal component analysis. Because it was difficult to quantify the impact of the national government policies on the arable land changes, the contributions of the national government policies to the changes in arable land were analyzed qualitatively. The primary conclusions of the study were as follows: between 1980 and 2010, the arable land area decreased. The trends of the year-end actual arable land proportion of the total area in the northern Shaanxi region and Yan’an City were broadly consistent, whereas the proportion in the Baota District had no obvious similarity with the northern Shaanxi region and Yan’an City. Remarkably different factors were shown to influence the changes in the arable land at different scales. Environmental factors exerted a greater effect for smaller scale arable land areas (the Baota District. The effect of socio-economic development was a major driving factor for the changes in the arable land area at the city and regional scales. At smaller scales, population change, urbanization and socio-economic development affected the crop yield per unit area either directly or indirectly. Socio-economic development and the modernization of agricultural technology had a greater effect on the crop yield per unit area at the large-scales. Furthermore, the qualitative analysis

    Socioeconomic disparities in birth weights (BWs) are associated with lifelong differences in health and productivity. Understanding socioeconomic disparities in BW is presently of concern to develop public health interventions that promote a good start in life in Northwest China. In the study, our objective is to investigate the socioeconomic disparities in low and high BW from 2010 to 2013 in this region.Those single live births were recruited using a stratified multistage sampling method in Shaanxi province from August to December 2013. Data were collected with a structured questionnaire and a review of birth certificates. Socioeconomic status (SES) was stratified based on the calculated household wealth index. Prevalence differences (PDs) and concentration indices (CIs) were used to depict the SES inequality of low BW (LBW) and macrosomia.Information for 28722 single live births born were obtained in Shaanxi province. From 2010 to 2013, the overall rates of LBW decreased, and the difference in LBW across differing SES groups decreased by 0.7% (boys, 0.4%; girls, 0.8%). From 2010 to 2013, the overall rates of macrosomia increased by 14.3% (boys, 17.5%; girls, 7.8%), whereas the PDs in macrosomia across various SES groups remained unchanged. From 2010 to 2013, concentration indices for SES inequalities in LBW and macrosomia confirmed the results shown by differences in prevalence. Compared with mothers of high SES, those in low SES group were significantly older, less educated, engaged in farming with less availabile healthcare, and engaged in unhealthy lifestyles (eg, exposure to secondhand smoke) during pregnancy, regardless of the baby's sex.From 2010 to 2013, in Shaanxi province, the negative association between socioeconomic status and LBW weakened. Rates of macrosomia were higher in those of high SES, but the SES disparities varied insignificantly over the same time. Our findings may provide valuable insights to direct healthcare policies for pregnant women

    Based on the investigation data of the vegetations in Hegou valley in Wuqi County of Shaanxi Province, this paper studied the vegetation characteristics on the five typical micro-topography categories including shallow gully, gully, collapse, platform, and scarp in the loess area of north Shaanxi, with the undisturbed slope as the control. There existed distinct differences in the species composition, quantitative characteristics, and species diversity of plant communities on the five typical micro-topography categories and the undisturbed slope. After twelve years of enclosure recovery, the study area formed herbaceous plant community, with Artemisia sacrorum and Artemisia giraldii as the dominant species. Among the main companion species, shrubs such as Prinsepia uniflora and Caragana korshinskii were found in scarp and gully, and hygrophyte Phragmites australis appeared in platform. The coverage, height, and biomass of the plant communities on most of the micro-topography categories, especially on the gully and collapse, were larger than those on the undisturbed slope. The Shannon index on the micro-topography categories and undisturbed slope was in the order of scarp > gully > shallow gully > undisturbed slope > platform > collapse.

    Chen, Jiangsheng; Yang, Hong

    Employing data from the China rural-urban mobility survey conducted in 2010, this study investigates the influence of family demographic characteristics on the income, life satisfaction, and potential for rural-urban mobility at the rural household level of two provinces of China: Shaanxi and Henan. A larger labor force in a rural household was found to reduce a family's ability or inclination to move to a city. The findings reveal that family size negatively affects the average income per family member and reduces the marginal income of the labor force and that minor children can improve the life satisfaction of family members. We conclude that a larger family size does not translate to more benefits for a rural household. Family size preference is found to be a reflection of parents' concerns about elderly care and is deemed to be unfavorable for urbanization in P. R. China.

    The re-employment of landless farmers in reconstruction of urban village is an important way to solve the problems concerning farmers. In S Village of Shaanxi Province,the landless farmers are facing the employment problems such as low re-employment rate and quality,lack of employment competitiveness,and weak employment willingness. This paper analyzes the main factors influencing the employment of landless farmers in this urban village such as local government’s lack of overall design on the employment of landless farmers,landless farmers’ lack of long-term employment concept,poor employment conditions,and lack of vocational education in rural areas. Finally some recommendations are set forth to enhance the employment of landless farmers in S Village: strengthening the institutional support for the employment of landless farmers; perfecting the fund guarantee for the employment of landless farmers; actively expanding the employment channels; enhancing the employability of landless farmers.

    In this investigation, we determined the concentrations of arsenic (As), fluoride (F), and selenium (Se) in the environment (coal, drinking water, soil, corn, and chilli) and in biological samples from local residents (urine, hair, and serum) from the endemic disease village of Dazhuyuan and the non-endemic disease control village of Liu in Shaanxi Province, China. Except for drinking water, the As and F levels of all samples from Dazhuyuan were significantly higher than those of the control. In contrast, although the Se contents in the environment of Dazhuyuan village were remarkably greater than those of the control, the Se levels in tissue samples from the exposed and control populations were similar. This study found for the first time that naturally occurring, high levels of As, F, and Se in the Dazhuyuan environment could contribute to local residents suffering from arsenicosis and fluorosis but not selenosis.

    Full Text Available Disease has become one of the key causes of falling into poverty in rural China. The poor households are even more likely to suffer. The New Cooperative Medical Scheme (NCMS has been implemented to provide rural residents financial protection against health risks. This study aims to assess the effect of the NCMS on alleviating health payment-induced poverty in the Shaanxi Province of China.The data was drawn from the 5th National Health Service Survey of Shaanxi Province, conducted in 2013. In total, 41,037 individuals covered by NCMS were selected. Poverty headcount ratio (HCR, poverty gap and mean positive poverty gap were used for measuring the incidence, depth and intensity of poverty, respectively. The differences on poverty measures pre- and post- insurance reimbursement indicate the effectiveness of alleviating health payment-induced poverty under NCMS.For the general insured, 5.81% of households fell below the national poverty line owing to the health payment; this HCR dropped to 4.84% after insurance reimbursement. The poverty HCRs for the insured that had hospitalization in the past year dropped from 7.50% to 2.09% after reimbursement. With the NCMS compensation, the poverty gap declined from 42.90 Yuan to 34.49 Yuan (19.60% decreased for the general insured and from 57.48 Yuan to 10.01 Yuan (82.59% decreased for the hospital admission insured. The mean positive poverty gap declined 3.56% and 37.40% for two samples, respectively.The NCMS could alleviate the health payment-induced poverty. The effectiveness of alleviating health payment-induced poverty is greater for hospital admission insured than for general insured, mainly because NCMS compensates for serious diseases. Our study suggests that a more comprehensive insurance benefit package design could further improve the effectiveness of poverty alleviation.

    Full Text Available Abstract Background The first 18 months of life are the most important for long-term childhood well-being. Anemia and malnutrition occurring in this key period have serious implications for individuals and societies, especially in rural areas in developing country. We conducted a cross-sectional study as the baseline survey to provide data for developing a policy-based approach to controlling infant anemia and malnutrition in rural areas of Shaanxi province in northwestern China. Methods We randomly sampled 336 infants aged 0–18 months in 28 rural villages from 2 counties of Shaanxi province. Anthropometric measurements and household interviews were carried out by well-trained researchers. The hemoglobin concentration was measured for 336 infants and serum concentrations of iron, zinc, and retinol (vitamin A were measured for a stratified subsample of 55 infants. Anemia was defined using World Health Organization (WHO standards combined with the Chinese standard for infants Results We found that 35.12% of infants in rural Shaanxi suffered from anemia, and the malnutrition prevalence rates were 32.14% for underweight, 39.58% for stunting, and 11.31% for wasting. Anemia was significantly associated with malnutrition (underweight, OR: 2.42, 95%CI: 1.50-3.88; stunting, OR: 1.65, 95%CI: 1.05-2.61; wasting, OR: 2.89, 95%CI: 1.45-5.76. Low birth weight, more siblings, less maternal education, low family income, crowded living conditions, and inappropriate complementary food introduction significantly increased the risk for infant anemia. Serum concentrations of iron, zinc, and retinol (vitamin A were significantly lower in anemic infants compared with non-anemic infants. Conclusions Specific socio-demographic characteristics and feeding patterns were highly associated with infant anemia in rural areas of Shaanxi province. Health education focusing on feeding practices and nutrition education could be a practical strategy for preventing anemia and

    A two-region ten-sector computable general equilibrium (CGE) model was built to analyze the effects of investment growth in the energy sectors of western areas of China on the local economy and emission of carbon dioxide (CO{sub 2}). There are three different scenarios in the quantitative analysis for the investment increase in energy sectors of the western areas. The investment to energy sectors is increased at the rate of 20%, 40%, and 60%. Based on Shaanxi Province's 2002 input-output table, the change of some macro-economic variables is simulated under these scenarios. The results show that the GDP growth is at 0-8.92%, households disposable income growth is at 0-8.94%, and emission of carbon dioxide growth is at 0-11.10% when the investment growth is at 0-60%. The oil and gas sector is the most effective sector with a growth rate of 0-19.47%. (author)

    Upland and paddy soils, as well as corn samples, were collected in the selenosis area of Naore Village, Ziyang County, Shaanxi Province, China. A five-step sequential extraction procedure was used for selenium (Se) fractionation, including soluble Se, exchangeable Se and carbonate-bound Se, iron and manganese oxide-bound Se, organic matter-bound Se, and the residual Se fraction. Species of soluble Se in upland soils included Se(-2), Se(4+), and Se(6+). The results showed that soluble Se and exchangeable Se fractions accounted for less than 1% of the total Se in the upland soil, but approximately 16.1% in the paddy soil. Concentrations of residual Se were lower than those of iron and manganese oxide-bound Se and organic matter-bound Se in both upland and paddy soils. Iron- and manganese oxide-bound Se was the dominant fractions in upland soil, whereas organic matter-bound Se abounded in paddy soil. Concentrations (mg kg(-1)) of Se in the corn samples ranged from 0.05 to 14.5 in seed, 0.31 to 12.3in root, 0.09 to 9.15 in stalk, and 0.16 to 36.15 in leaf.

  15. δ13CSC values of the loess-paleosol sequence in Dali area, Shaanxi Province, China, and paleoenvironmental implications

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The carbon isotopic ratios of carbonate in the two profiles of the Dali area were analyzed and some new understandings on the influencing factors of the δ13CSC value of the loess-paleosol sequence and its paleoenvironmental implications were discussed preliminarily in this report. The 13CSC value of the Dali loess-paleosol sequence is synchronizing with the variance of magnetic susceptibility basically and the negative peaks of the δ13CSC curves are corresponding to the different developmental periods of the paleosol. It is believed that the intervention of the CO2 produced by plants will cause the decrease of the δ13CSC value, the amplitude of which may be relevant to the paleovegetation density and the ancient humidity. The relative biomass of C4 plants in the vegetation will affect the sublevel change of the δ13CSC. Low δ13CSC value by and large indicates the environmental conditions of the relatively abundant vegetation and humid climate. During the last 250000 years, the period with the sparsest vegetation and the most arid climate is the phase of the loess in L2 depositing and the period with the most abundant vegetation and the most humid climate is the last interglacial period. The δ13CSC curves of Dali also show that the High Temperature and Large Precipitation Event of the Qinghai-Tibetan Plateau during 40-30 kaBP had affected the Central Shaanxi Plain with relatively humid climate, and had apparent influence on the local vegetation and humidity.

    A 7-year (2003-2010) located field experiment was conducted to evaluate the effects of different long-term fertilization patterns on the Fuji apple yield, quality, and soil fertility on the Weibei Dryland, Shaanxi Province of Northwest China. Seven treatments were installed, i. e., no fertilization (CK), inorganic P and K fertilization (PK), inorganic N and K fertilization (NK), inorganic N and P fertilization (NP), inorganic N, P, and K fertilization (NPK), swine manure (M), and half inorganic N, P, and K combined with half swine manure (NPKM). Each treatment had three replications. Fertilization increased the apple yield. The average yield in the 7 years under fertilization was increased by 14.4%-63.8%, as compared to the CK. The average yield decreased in the order of NPKM > NPK > or = M > NP > or = NK > PK > CK. In treatments NPKM, M, and NPK, the fruit sugar/acid (S:A) ratio, vitamin C, soluble solid, and hardness tended to be increased with time, with a smaller yearly fluctuation in treatments NPKM and M. In treatment NPKM, the S:A ratio and vitamin C increased by 30.9% and 17.5%, respectively after five years, as compared to the CK. Long-term rational fertilization increased the soil organic matter (SOC) content in 0-20 cm layer, with the largest increment in treatments NPKM and M (28.8% and 29.3%, respectively). The soil available N, P, and K contents in all layers in treatments NPK, NPKM, and M increased significantly, and the soil available N content in 0-20, 20-40, and 40-60 cm layers in treatment NPK was increased by 22.7%, 37.3%, and 53.4%, respectively. As compared to treatment NPK, the soil available P content in treatment NPKM was increased by 18.7%. In all fertilization treatments, the soil available Pcontent was significantly higher in upper layer than in lower layer.

    Full Text Available Problem statement: There are quite a few active faults recently found in the western and northern parts of Thailand, which could possibly induce earthquakes of magnitude (ML of 5.5-6.5. Although seismic design code has been enforced in the area since 1980, the fundamental knowledge on dynamic soil behavior has not been extensively attained. Approach: Collection of existing borehole information in the targeted areas to form a typical subsoil profile. This borehole information, together with analytical result obtained from logistic regression based on worldwide liquefaction database was used to conduct an effective stress analysis. Result: Literature reviews of the existing boreholes from the two largest provinces in the north, Chiang-Mai and Chiang-Rai, revealed that the areas were underlain by layers of loose to medium dense sand found at shallow depths. The corrected SPT N-value of those sand layers varies in the range of 5-20. A simple tool correlating the liquefaction probability, which correlated excess pore water pressure and peak ground acceleration, was proposed for the studied areas. Conclusion: The proposed correlation provided preliminary tool to evaluate risk of the shallow foundation from partial liquefaction in the two northern provinces of Thailand.

    This article studies the soil moisture conditions of 30 years artificial Robinia pseudoacacia in the north of Shaanxi under different climate conditions in order to explore the relationship between soil moisture and impact factor of Robinia pseudoacacia in this area,and variation characteristics of soil moisture in the Loess Plateau region. The results show that soil moisture content decreases with increase of soil depth, and in 40- 50 cm depth the jump point of moisture reduction appears significantly. Soil moisture was lower than the growth critical moisture in 5 samples to the north of Chunhua,and has different degrees of deficit. Soil moisture deficit degree was more than 50% in sandy loam and light loam soils such as Yulin,Shenmu and Suide. With the increasing of latitude,both of soil accumulative storage and net rainfall tends to decrease,but the relationship between them is significant correlation,indicating that that climate conditions are the major factors causing significant difference of soil moisture.

    2008-01-01

    A field survey was conducted in the grain-for-green land of the loess region,northern Shaanxi,China,from July to August of 2005 to provide a scientific evaluation of the grain-for-green project,including its soil and water conservation and other ecological benefits for the region.The distribution of microbiotic crusts were studied,while human disturbance,aspect,topography,vegetation structure and other factors affecting it were obtained from the analysis of survey data from 78 sample plots.Results show that crust coverage is larger on lessdisturbed plots than on highly-disturbed ones,on northfacing plots than on south-facing ones and on gully-slopes than on ridge-slopes.Coverage increases with herbal coverage and trees can provide better conditions for distribution of crusts than shrubs.Therefore,crust coverage is larger in herb-dominated plots than in tree-dominated ones and crusts in shrub-dominated plots are smaller.However,we made no progress in our study on deciding how slope degrees and herb species affect the distribution of crusts.We believe that more studies are necessary for a further exploration of the relationship between them.

    Water footprint, proposed by professor Hoekstra, is a new indicator of water consumption, which includes both direct and indirect water use. Water footprint of crop production is the volume of water consumed in producing per kilogram of crop. It not only reflects water use efficiency, but also the real water occupation in the process of agricultural production. This paper calculated both green and blue water footprints of crop production. For crop production, green water footprint reflects how much green water is consumed by producing per kilogram of crop, and blue water footprint is water consumed from sources such as surface water or groundwater. Quantification of crop water footprint will contribute to our knowledge of determining water utilization conditions in agricultural production and provide theoretical basis for improving water use efficiency by optimizing cropping patterns in relation to local water resources endowment. Using Shaanxi Province as the study area, this paper calculated water footprint of crop production (WFP) using a modified method that took into account water evaporation loss during transmission and distribution processes of water in crop fields. The paper then used the (blue) water stress indexesβt (βb) to determine the relationship between water resources and total/blue water footprints. Finally, the temporal and spatial distributions of WFP,βt andβb in Shaanxi Province were analyzed. The results showed large differences in WFP among crops and crop production areas, with a general declining trend in WFP. Water footprint of integrated crop production (IWFP) in Shaanxi Province dropped from 1.132 m3·kg−1 to 0.931 m3·kg−1 from 2000 to 2012. While Xi’an City had the lowest average IWFP (0.849 m3·kg−1), Yulin City had the highest one (1.730 m3·kg−1). The average annual total crop water footprint (WF) of Shaanxi Province was 127.39×108 m3, with green water footprint (GWF) proportion of 50.22%. With similar spatial

    By determining the earth moisture content of artificial forestland between 0 and 6 m deep in the Loess Plateau of Shaanxi province, the vertical change of moisture content,distribution and formation causes of a dried earth layer are researched. The results show that the average moisture content is 9.3%-9.5% between 2 and 4 m under artificial forest of over 10 year's growth in Guanzhong Plain, and chronic weak dried earth layers are developed which show that the dried earth layers are distributed extensively on the Loess Plateau. The southern boundary of the dried earth layer has reached the northern foot of the Qinling Mountains. When precipitation reaches 600 mm, there are weak dried earth layers between 2 and 4 m under artificial forest of more than 10 years old. When the precipitation is between 400 and 500 mm, there are moderate dried earth layers. When precipitation is above 800 mm,there are no dried earth layers. There are no dried earth layers under meadow land, corn land and less than 5 years old of artificial forestland in central and southern parts of the Loess Plateau. The development of dried earth layers under cypress forest is weaker than broad-leaved forest. Under the same climatic conditions, the development of dried earth layers under the loess tableland is nearly at the same level as the 2nd and 3rd river terrace.Dried earth layers developed in membrane water zone, and the buried depth is small and motion velocity is slow in the Loess Plateau, which is the direct water factor of the formation of the dried earth layer, while differences of tree age and tree species are the plant factors that consumed much moisture. From the depth of the gravity water and the membrane water in Guanzhong Plain, it is clear that the formation cause of dried earth layers is mainly due to natural factors. The dried layers generally develop in middle-aged artificial forestland that consumed too much moisture, which is the general character of earth moisture in subhumid

    Multi-Agent Systems (MAS) offer a conceptual approach to include multi-actor decision making into models of land use change. Through the simulation based on the MAS, this paper tries to show the application of MAS in the micro scale LUCC, and reveal the transformation mechanism of difference scale. This paper starts with a description of the context of MAS research. Then, it adopts the Nested Spatial Choice (NSC) method to construct the multi-scale LUCC decision-making model. And a case study for Mengcha village, Mizhi County, Shaanxi Province is reported. Finally, the potentials and drawbacks of the following approach is discussed and concluded. From our design and implementation of the MAS in multi-scale model, a number of observations and conclusions can be drawn on the implementation and future research directions. (1) The use of the LUCC decision-making and multi-scale transformation framework provides, according to us, a more realistic modeling of multi-scale decision making process. (2) By using continuous function, rather than discrete function, to construct the decision-making of the households is more realistic to reflect the effect. (3) In this paper, attempts have been made to give a quantitative analysis to research the household interaction. And it provides the premise and foundation for researching the communication and learning among the households. (4) The scale transformation architecture constructed in this paper helps to accumulate theory and experience for the interaction research between the micro land use decision-making and the macro land use landscape pattern. Our future research work will focus on: (1) how to rational use risk aversion principle, and put the rule on rotation between household parcels into model. (2) Exploring the methods aiming at researching the household decision-making over a long period, it allows us to find the bridge between the long-term LUCC data and the short-term household decision-making. (3) Researching the

    2004-01-01

    The authors presented the enzyme characteristics of catalase, sucrase, urease and alkaline phosphatase under agroforestry systems in northern Jiangsu Province. The results show that soil enzyme activities reduce gradually from top to bottom layer of the soil profile, and the fluctuations of catalase and urease are smaller than those of sucrase and alkaline phosphatase. Soil enzyme activities differe significantly in different samples, and the order is arranged as poplar-crop intercropping segment (A, D) > paulownia-crop intercropping segment (B, C) > CK. Furthermore, soil enzyme activities increase with intercropping age. On the other hand, in the same plot, there are closer relationships between enzymes in the soil samples. Catalase, alkaline phosphatase and urease are negatively related, while alkaline phosphatase and urease are positively related (except in samples B and C). In addition, the enzyme activities have a close relationship with the fertilizers. Catalase is positively correlated with the soil pH value (r = 0.854, 0.804, 0.078 and 0.082, respectively), and is negatively correlated with total N (r = -0.201, -0.529, -0.221 and -0.821, respectively), total P (r = -0.143, -0.213, -0.362 and -0.751, respectively) and available P (r = -0.339, -0.351, -0.576, and -0.676, respectively). Sucrase, urease and alkaline phosphatase are negatively correlated with the pH value, while positively correlated with the other fertilizers (r ≈ 1). The authors suggest that enzyme activity will be a great potential as an indicator of soil quality.

    Full Text Available Accurately identifying the spatiotemporal variations and driving factors of ecosystem services (ES in ecological restoration is important for ecosystem management and the sustainability of nature conservation strategies. As the Green for Grain project proceeds, food provision, water regulation and climate regulation services in the Northern Shaanxi Loess Plateau (NSLP are changing and have caused broad attention. In this study, the dynamic pattern of the normalized differential vegetation index (NDVI and the main drivers of grain production (GP, water yield (WY and net primary production (NPP in the NSLP from 2000–2013 are identified by incorporating multiple data and methods, in order to provide a better understanding of how and why ES change during ecological restoration. WY was simulated by hydrological modeling, and NPP was estimated with the Carnegie Ames Stanford Approach (CASA model. The results show that vegetation restoration continued from 2000–2013, but fluctuated because of the comprehensive influence of climate and human activity. GP and NPP both exhibited significantly increasing trends, while changes in WY occurred in two stages: decline (2000–2006 and growth (2007–2013. Spatially, significantly increasing trends in NPP and WY were detected in 52.73% and 24.76% of the region, respectively, in areas that correspond with the Green for Grain project and high precipitation growth. Correlation and partial correlation analyses show that there were different dominant factors (i.e., natural vs. anthropogenic driving ES change in the NSLP from 2000–2013. The change in WY was mainly driven by precipitation, while the improvements in GP and NPP can be attributed to investments in natural capital (i.e., chemical fertilizer, agricultural machinery power and afforestation. We also found that vegetation restoration can produce positive effects on NPP, but negative effects on WY by using response analyses of WY or NPP change to NDVI

    Root xylem anatomical structure and hydraulic traits of three typical shrubs, i.e., Salix psammophila, Caragana korshinskii and Hippophae rhamnoides, within two soil layers (0-20 cm and 30-50 cm) were compared. The results showed that S. psammophila had a higher leaf water potential than C. korshinskii and H. rhamnoides, the average maximum and minimum lumen diameter (d(max) and d(min), respectively), the average lumen area of vessels (Alum) and the ratio of lumen area of all vessels to xylem area (Aves/Axyl) in S. psammophila roots were also significantly higher than those in C. korshinskii and H. rhamnoides, and the root vessel density (VD) in S. psammophila was the same as that in H. rhamnoides but significantly higher than that in C. korshinskii. Root hydraulic conductivity in S. psammophila was 5 times of C. korshinskii and 2.8 times of H. hamnoides. The vulnerability index in S. psammophila roots was similar to that in C. korshinskii but higher than that in H. hamnoides. S. psammophila belonged to a water-spending species, whereas both C. korshinskii and H. rhamnoides were water-saving species, and C. korshinskii was more drought-resistant than H. rhamnoides. There was no difference of d(max), d(min) and Alum between roots in two soil layers, but roots within in the 30-50 cm soil layer had larger VD and Aves/Axyl. The root specific hydraulic conductivity within the 30-50 cm soil layer was significantly higher than within the surface soil layer, whereas the vulnerability index within the 30-50 cm soil layer was smaller, indicating roots in deep soil layers had higher hydraulic transport efficiency and lower hydraulic vulnerability.

    农业在陕西省经济发展中处于基础性地位,但随着农业产业化的进程,农业融资面临瓶颈。农业产业链融资是一种新型融资方式,能将整条产业链看作一条信誉链,产业链上企业之间信誉共享,金融机构通过重点考察产业链和核心企业,从而解决链条上广大中小企业和农户的融资难题。陕西省的农业产业链融资为农村经济的发展作出了一定的贡献,但龙头企业整体实力不强、金融机构信贷风险增加和法律法规不健全等因素制约了农业产业链融资的进一步发展。未来应着重发展壮大龙头企业、发挥金融机构的支撑作用并健全相应的法律法规。%Agriculture is at the fundamental status in Shaanxi Province’ s economic development, but with the process of indus⁃trialization of agriculture, agricultural finance is facing a bottleneck. Agricultural industry chain financing is a new and innovative fi⁃nancing model. The whole industry chain can be seen as a reputable chain. Reputation is shared between the industry chain enterpri⁃ses, financial institutions, and by the emphasis on the industrial chain core business, so as to solve the chain of medium and small enterprises and farmers of financing difficulties. Shaanxi Province agricultural industry chain financing for rural economic develop⁃ment has made some contribution, but the overall weak point is only a few strong enterprises, financial institutions credit risk increa⁃ses and improve laws and regulations problems. In future, we must focus on the development and expansion of enterprises, financial institutions should play a supporting role and improve relevant laws and regulations.

    陕北是原始人类栖居生息和繁衍地之一,是创造原始文化的密集区。有史以来,陕北各民族蜂拥迁徙,在相互友好或相互排斥的复杂过程中达到民族融合,形成了陕北人。在流迁方向上,有北方各少数民族的内迁;也有内地汉族的外移。在融合方式上,有通过战争、和亲、移民、流放、戍边军人和筑墙劳工滞留等急剧的强迫性、半强迫性的政治、军事原因,也有和平时期作为谋生方式的下层人民的被迫自觉迁徙。“徙民实边”、“走西口”的人口机械流动,十六国北朝时期的军事征服涵化,造反暴动的强制变化,稽胡、龟兹等少数民族获得内迁保护的诉求涵化,艰苦的生存环境和特殊的生存方式衍化种种,是形成现代陕北人的主要原因。%Northern Shaanxi is one of the dwelling habitats and breeding areas of the primitive people and it is an accumulated area to create a primitive culture. In history,the various nationalities flocked to migrate,and ethnic integration formed in northern Shaanxi in the complex process of mutual friendship and mutual exclusion. For the migration direction,the ethnic minorities in the north migrated inward;and there were also mainland Han Chinese migrated outwards. For the fusion method,there were sharp obsessive compulsive,semi political and military rea-sons by war,marriage,immigration,exile,garrison soldiers and wall building labor retention,there were also times of peace when the lower class people consciously migrate as a way to make a living. The main reasons for the formation of the modern Northern Shaanxi people are population flow caused by "people who migrated to solid bor-der","moving westward";the acculturation by military conquest in the Sixteen States of Northern Dynasties;forced change by rebel insurgency;the acculturation of the appeal to be protected by migrating inwards by the eth-nic minorities such as Ji Hu

    The structure of financial market is a relatively independent system in which quantity is in unity with quality. The structural optimization of the financial market directly reflects the development of financial market in a country or a region. The unbalanced development of financial market restricts the financial market from giving a full play to its functions as a whole and improving its kernel competitiveness. From the perspective of the unbalanced structure in Shaanxi regional financial market and the low efficiency of intermediary institutes, suggestions are made as follows: to perfect the regional financial market system and ecological construction in order to improve its efficiency; to establish more intermediary institutes in order to lift its financial level.%金融市场结构是质与量相统一的相对独立系统,一个国家或区域的金融市场结构优化与否直接反映了其金融市场发展水平的高低,金融市场结构的失衡制约了金融市场整体功能的充分发挥和核心竞争能力的进一步提升。针对陕西区域金融市场供求结构失衡、金融中介机构效率较低等问题,应完善区域金融市场体系和生态环境建设,提高金融体系运行效率;大力发展各类金融中介机构,不断提升经济发展的金融化水平。

    Full Text Available The climate of Doi Tung, Chiang Rai Province, is monsoonal with three distinctseasons, viz. cool-dry, hot-dry, and rainy. The elevation ranges from c. 350-1525m and mostof the bedrock is limestone and granite. Vegetation below c. 1000m is mostly deciduous,while above this it is evergreen. A mixed evergreen + deciduous facies is present on thelimestone peaks (up to 1425m. Forest destruction as well as settlements are widespread,thus creating increasingly severe problems with water resources, soil quality and stability, andbiodiversity. The planting on pine monocultures in deforested areas 20 years ago in uplandgranite areas has resulted in much environmental degradation which requires immediaterectification.

    The Shenhe barium deposit in Shaanxi Province occurs in the northern ore zone of the early Paleozoic South Qinling barium metallogenic belt. Barite and witherite are main ore minerals. Microthermometric analyses show that the homogenization temperature ranges of the fluid inclusions in barite, witherite and barytocalcite are 108 -205°C(with main peak at 130~170°C), 118-274°C (with main peak at 150-210°C) and 146~227°C,respectively, and the salinity ranges of the fluid inclusions in the barite, witherite and barytocalcite zv(NaCleq) are 0.53% ~ 9.86% , 0.18% ~ 8.95 % and 4.03% ~ 7.31 % , respectively. Laser Raman analyses show that the gas and liquid phase composition of the fluid inclusions in barite is H2O, the gas phase compositions of the fluid inclusions in witherite are composed of CO2, N2, H2S and CH4, the gas phase compositions of the fluid inclusions in barytocalcite include CO2 and N2, and the gas phase compositions of the fluid inclusions in quartz consist of CO2, N2, H2S and CH4. It is concluded that metallogenic conditions of various kinds of barium minerals were different. The formation of witherite was possibly associated with thermochemical sulfate reduction, which consumed lots of organic gases and SG4 in hydrothermal fluids and also inhibited the formation of barite when witherite was formed. The authors thus hold that thermochemical sulfate reduction transferred carbon from organic gases into witherite. Relatively high fluid temperatures, the existence of CO2, fairly high Ba + concentrations, and the environment of high HS concentrations and rapid diffusion of H2S in ore-forming fluids before thermochemical sulfate reduction constituted important factors for witherite formation.%陕西神河钡矿床位于南秦岭钡成矿带的北矿带,重晶石和毒重石为主要的矿石组成.显微测温分析表明,重晶石、毒重石和钡解石内流体包裹体的均一温度范围分别为108~205℃(峰值130~170℃)、118~274

    Described in detail in this paper are the geochemical characteristics of the sandstone-type uranium deposits in northern Sichuan Province .Favorable and unfavor-able conditions for the enrichment of uranium are explored on the basis of the elemental abundances and ratios of U,Th and K determined by gamma-ray spectroscopy. Gamma-ray spectroscopic(U, Th and K) and XRF analyses(As, Ba) are helpful to distinguish U-bearing light-colored sandstones from U-barren light-colored ones and red sandstones (red claystone) from light-colored sandstones. Therefore, the favorable target area for prospecting the sandstone-type uranium deposits can be difined in northern Sichuan Province.

    Urbanization is the indispensable stage of modernization. Accurate prediction of urbanization is base for economic and social construction. On the basis of structural break theory, this paper applies the logistic model to analyze the urbanization in Shaanxi province. The conclusion of research shows that 1999 is a structural break point of urbanization in Shaanxi province, it means that the exogenous shocks have a great impact on the urbanization in Shaanxi province. Laid off workers due to State - owned enterprise reform increased employment difficulty of migrant workers. The goodness of fit improved obviously whether threshold equal to 0.8 or equal tol. 0 by phased predic- tion. The goodness of fit increased from 0.21 to 0.89 and 0.98 on threshold 0.8 by phased logistic forecast model including 1978 to 1999 and 2000 to 2010,the goodness of fit increased from 0.25 to 0.90 and 0.98 on threshold 1. 0 by phased logistic forecast model including 1978 to 1999 and 2000 to 2010 ,while the precision of model is higher on threshold 1.0 than on threshold 0.8, it means the urbanization in Shaanxi province is accelerating, the prediction shows the level of urbanization in Shaanxi province will reach 70% or so in 2030. in general,from 1984 to 2030 is accelerating stage of urbanization in Shaanxi province. The housing problem, population expansion, environmental degradation, traffic jam, security problem in accelerating stage of urbanization must be handled properly. The innova- tion of this paper is combination structural break theory with logistic model, increased sphere of application and pre- cision of prediction of logistic model.%城市化是走向现代化的必经阶段,准确的城市化预测是进行经济、社会建设的基础。在结构突变理论的基础上,用Logistic模型对1978~2010年陕西城市化率进行分析。结论表明:1999年为陕西城市化率的结构突变点,说明城市化率的增长受到外部冲击的影响,分段以后的拟

O'Donnell, Gabriel Mbogoni, Gabriel Mulibo, Richard Ferdinand, Patrick Chindandali, Felix Mphepo, Gabrielle Tepp, Godson Kamihanda We investigate crustal structure around the northern end of Lake Malawi and in the Rungwe Volcanic Province using teleseismic receiver functions from the SEGMeNT broadband seismic network. The SEGMeNT network includes 55 broadband stations deployed in northern Malawi and southern Tanzania, with station spacing of 20-50 km. Fourteen stations were deployed in August 2013, and an additional of 41 stations were added to the study region beginning June/July 2014. Fifteen stations are located in Malawi and 40 stations in Tanzania. Data from teleseismic earthquakes with magnitude 5.5 or greater in the 30 to 90 degrees distance range have been used to calculate P-wave receiver functions. Estimates of Moho depth and Vp/Vs ratios have been obtained by using the H-k stacking method and by jointly inverting the receiver functions with Rayleigh wave phase velocities. Preliminary results show an average Moho depth of 40 km and an average Vp/Vs ratio of 1.72. Little evidence is found for magmatic underplating beneath the Rungwe Volcanic Province.

    The water environment condition of Weihe River reach in Shaanxi Province was analysed in terms of integrated water quality and quantity, based on the data collected over the period from 2000 to 2008. Moreover, the correlation between runoff and COD, NH3-N were major discussed at the main hydrological stations in Weihe River reach. The results show that the middle and lower stream of Weihe River reach in Shaanxi Province has already been polluted. The concentrations of COD, NH3-N BOD3 and DO exceed the national surface water quality standards from Xingping control section to Tongguan control section. The available water resource descends in terms of the runoff volume of Weihe River reach. The scarcity of water resource resulting from the water quality problems has been more and more severe in the region. The concentrations of COD, NH3-N correlate to the runoff weakly in the upstream of Weihe River, while the average negative correlation between the pollutant concentrations and runoff is shown in middle and lower stream of the Weihe River. Comparatively, the influence of runoff in Weihe River on COD is more aparent than that on NH3-N.%为了全面掌握渭河(陕西段)干流水资源变化总体情况,本文收集2000 - 2008年陕西段渭河干流水文、水质监控断面的监测资料,分别从水质、水量以及两者相结合的角度分析了渭河干流的水环境状况,并重点讨论了渭河干流主要水文站径流量与COD、NH3-N污染物的同期监测浓度的相关关系.结果表明:渭河干流(陕西段)中下游水体水质为劣Ⅴ类,已受到严重污染.渭河干流可利用的水资源量有所下降,其中80%以上的水资源水质为Ⅴ类,不能满足水体利用的水质目标要求,渭河干流“水质型”水资源短缺的问题凸显.渭河干流上游径流量与COD、NH3-N污染物的浓度呈低相关性,随着流程变化,径流量与COD、NH3-N污染物的浓度在渭河干流的下游华县水

    Full Text Available The grazing capacity of a game ranch in Northern Province was estimated in a number of different ways using rainfall and herbaceous composition and phytomass data. The results indicate that the grazing capacity under the present environmental conditions should be approximately 50 of the recommended agricultural grazer stocking rate. This is in agreement with recent literature, indicating that the methods used should be suitable for determining a first approximation of grazing capacity in the mixed bushveld of Northern Province.

    ecological risk of heavy metals in the surface sediment of Hongjiannao Lake:(1) the comparison of samples in Hongjiannao Lake with the Environmental Quality Standard for Soils in China (GB 15618—1995) (EQSS). (2) The enrichment factor (EF) to show the state of the enrichment for each element relative to the reference system. The reference system is selected respectively as soils in Shaanxi Province to show the enrichment relative to the local environment, and the upper continental crust (UCC) to show the enrichment relative to the global mean content of upper continental crust. And (3) the potential ecological risk index (RI) to assess the potential risk of the toxicity of heavy metals to the lake ecosystem. Results The result shows that the heavy metals in the surface sediment of Hongjiannao Lake are generally at a low level. The order of content from higher to lower is Cr>Zn>Pb>Hg>Cu>As>Cd. Except for Pb, As and Cr, the coefifcient variations (CV) of other four metals (Cd, Cu, Zn and Hg) among twelve sites are higher than 0.55 with Cd to be the highest in 0.68. Obviously, the contents of heavy metals of the surface sediments in the center of the lake (sites 7 to 12) are higher than those near the lakeshore (sites 1 to 6). Discussion Compared with the EQSS, the mean value of each heavy metal is within the upper limit value of the ifrst class soil in EQSS, indicating that the risk of heavy metals to this lake is at a lighter degree. Even for the maximum value of each element among the twelve samples, most of them are within the upper limit value of the ifrst class soil in EQSS, except for Cd. There are only two samples with the maximum value of Cd extend the upper limit value of the second class soil in EQSS. For most elements in the surface sediment of Hongjiannao Lake, the values of enrichment factor are lower than 1, indicating that there is no obvious enrichment for most elements, except for Cd and As. Cd assumes obvious enrichment both relative to soils in Shaanxi

The likelihood that individuals with selected chronic diseases would report any problem in the EQ-5D dimensions was calculated and tested relative to that of each of the two reference groups. Multivariable linear regression models were used to investigate factors associated with EQ VAS. RESULTS: The most frequently reported problems involved pain/discomfort (8.8% and anxiety/depression (7.6%. Nearly half of the respondents who reported problems in any of the five dimensions were chronic patients. Higher EQ VAS scores were associated with the male gender, higher level of education, employment, younger age, an urban area of residence, access to free medical service and higher levels of physical activity. Except for anemia, all the selected chronic diseases were indicative of a negative EQ VAS score. The three leading risk factors were cerebrovascular disease, cancer and mental disease. Increases in age, number of chronic conditions and frequency of physical activity were found to have a gradient effect. CONCLUSION: The results of the present work add to the volume of knowledge regarding population health status in this area, apart from the known health status using mortality and morbidity data. Medical, policy, social and individual attention should be given to the management of chronic diseases and improvement of HRQoL. Longitudinal studies must be performed to monitor changes in HRQoL and to permit evaluation of the outcomes of chronic disease intervention programs.

    陕北民歌的调式及记谱问题,历来充满争议。在以十二平均律为基础的基本乐理中,调式问题被忽略了,以至于同一首歌会出现三种记谱,这无疑是不符合实际的。本文以《咱们的领袖毛泽东》为例,分析了同一曲调的调高变化在记谱中的反映,指出了记谱虽然在一定情况下可以通融,但调式不可含混。%The issue of musical modes and notations of folk songs in Northern Shaanxi has been quite controversial. As fundamental music theories based on the twelve equal temperaments ignore the question of musical modes, a song may have three types of notations, which is indeed unrealistic. Taking the song Our Leader Mao Zedong as an example, this paper analyzes the change of musical modes in the same sentence and its reflection in the notation. The study also points out that although notations can be accommodated under certain circumstances, modes can never be ambiguous.

    The beiwusheng huiguan (`Meeting hall of the Five Northern Dynasties') is a building complex from the Qing dynasty (1636-1912 ad) located in Wafangdian, near Ziyang, in the south of the Chinese Province of Shaanxi. Two of the preserved halls are richly decorated with wall paintings dated probably in 1848 ad and representing scenes of the `Romance of the Three Kingdoms' and Confucian moral tales. They are a rare example of well-preserved mural paintings of high artistic value inside civil buildings. The aims of this paper are the chemical characterization and localization of organic materials used as binders and colorants in the wall paintings. A multi-analytical approach, consisting in the combined use of gas chromatographic-mass spectrometric techniques (GC/MS and Py-GC/MS) and high-pressure liquid chromatography with diode array detector (HPLC-DAD), was chosen for these purposes. Proteinaceous materials (animal glue and egg), saccharide material (fruit tree gum) and a siccative oil were identified in different paint layers supplying invaluable information about the painting technique used. Moreover, the analyses of organic dyes allowed identifying indigo and gallic acid in more than one sample adding fundamental information about Chinese artists' techniques in mural paintings, missing from the previous studies. To shed light on the gilding technique, the distribution of the painting materials was achieved by means of synchrotron radiation Fourier transform infrared spectroscopy (SR micro-FTIR) and X-ray fluorescence (SR micro-XRF). The results obtained from the multi-analytical approach enabled us to determine the organic materials both binders and organic colorants used by Chinese artisans, highlighting the high technical level achieved in nineteenth century. The binding media and the organic colorants identified, as well as their distribution, allowed the discussion on the painting technique used by the artists of the Qing dynasty giving information for the

    The study on the interrelation between sea-level changes and biodiversity with its evolution has great significance for understanding the impact of global changes on organic evolution and exploring the inherent laws of life-environment coevolution in geological history. In this paper, the stratigraphic distribution of fusulinacean fauna in the Carboniferous-Permian boundary section at Xikou, Zhen'an County, Shaanxi Province, is analyzed quantitatively, and the relationship between the species diversity of fusulinaceans and relative sea-level changes is discussed. As a whole, the species numbers of fusulinacean fauna experience a rapid increase and an obvious decline in Xikou,Zhen'an County, from the Late Carboniferous to the Early Permian. There is a significant increase in species diversity around the Carboniferous-Permian boundary, which is one of the biggest bio-events of the fusulinacean fauna, and represents the radiation of Pseudoschwagerininae subfamily in the studied area. Integrated fusulinacean species diversity into sequence stratigraphic framework, detailed study suggests that the species diversity of the fusulinaceans is closely related to its relative stratigraphic location, and is essentially controlled by the sea-level changes, especially by the high-frequency sea-level changes. Generally, the species diversity of fusulinaceans is low, andthe number of first and last appearance datum is small in the lower unit of high-frequency depositional cycle formed during the quick rise of the sea level; whereas the species diversity of fusulinaceans is high, and the number of first and last appearance datum is large in the upper unit of high-frequency cycle formed during the slow fall of the sea level. Within the third-order depositional sequence, the species diversity of the fusulinaceans at the first flooding surfaces and the maximum flooding surfaces is low, and it increases upward. The fusulinacean species diversity is low within the transgressive systems

    Shaanxi Province is the largest apple production region in China. Realizing high-yield and high-quality of apple production plays an important role in ensuring the farmers income. However, there exist some problems in apple production such as excessive application of nitrogen fertilizer and unreasonable use of microelements fertilizer. In order to promote rational fertilization of apple production in Weibei Dry Highland, the mineral nutrient content in red Fuji apple leaves during different growth stages were determined. Apple tree leaves were sampled at June, July and August respectively in Heyang County, Shaanxi Province, and contents of mineral nutrients were analyzed. Then DRISes proposed by Beaufils, Jones and Elwali & Gascho was used to diagnose nutrient status and requirements of red Fuji apple tree. Results showed that nutrients contents in apple leaves varied from June to August. During this period, high yield trees (yield > 25 kg per tree), N content decreased in July and then increased slightly in August, while P content decreased all the time. For low yield trees (yield < 25 kg per tree), N content decreased all the time, the change of P just followed the tendency of N in high yield trees. Other nutrients showed the same trend in both kinds of trees: K and Zn decreased; Ca and Mg increased; Cu, Fe and Mn increased in July and then decreased in August. The diagnosis parameters determined by DRIS standard program were different during different periods. Compared with the diagnosis indices calculated with method of Elwali & Gascho, those with methods of Beaufils and Jones were significantly correlated with nutrient content, and the corresponding order of nutrient requirement was similar. From June to August, the elements needed mostly were K, Fe, Ca+Mg by Beaufils and K, Ca, Ca+Mg by Jones for high yield trees, and K, Fe, N for low yield trees. The results suggested that leaf nutrient diagnose should be conducted during different growth periods of red Fuji

    Full Text Available Rodents are mammals that comprise more than 2000 species and approximately 30 families. There are many morphological and ecological differences among them as variations in their shape, size, weight and habitat. In addition to significant economic losses, rodents have a major role in the dissemination of infectious diseases caused by viruses, bacteria, parasites or other micro-organisms. Rodents are important reservoirs of diseases which have been observed in many cities of Iran provinces especially along Caspian Sea border to Alborz Mountain. The aim of this study is to assess the geographical distribution of rodents in three provinces of northern part of Iran as reservoir of potential endemic infectious diseases. Rodents in 10 major parts of each of the three provinces of Mazandaran, Gilan and Golestan, northern Iran were collected and a total of 404 rodents were trapped alive. They were determined by the key characteristics such as gender, genus, species, different locations and topological situation. Statistical analysis was performed to characterize the study sample and to correlate all variables and parameters. The distribution frequencies of three, five and six genera of rodents were identified in Mazandaran, Gilan and Golestan provinces respectively. The overall distribution frequency of eight genera of rodents in the three provinces were identified as Rattus (R. norvegicus (67.3%, R. rattus (13.6%, Apodemus sylvaticus (13.9%, Arvicola (1%, Mus musculus (0.3%, Nesokia indica (2.5%, Cricetulus migrates (0.7% and Rhombomys opimus (0.7%. The results of this study determined the geographic distribution of the rodents in the three northern provinces of Iran. It is indicated the association of various distribution and diversity of rodents with provincial location.

    In this paper, we present a study about cultural astronomy among European colonists and their Argentinean descendants, in the context of a complex interaction between criollos, aboriginals and European colonists from different origins and religions, who settled in the northern area of the Argentinean province of Santa Fe, which is part of the southern Gran Chaco. These colonists arrived among waves of immigration occurring in Argentina in the second half of the nineteenth century and the first half of the twentieth century. Through ethnographic field research among these immigrants and their descendants, we carried out a survey of their astronomical representations and practices, and the connections of these with their social life and farming tasks. Through this we gained an insight as to how the astronomical ideas of immigrants, criollos and aboriginal groups influenced each other, generating a variety of new relations with the celestial realm.

    Full Text Available The purpose of the study was to assess the concepts and treatment modalities for diabetes among traditional and faith healers in the Northern Province in South Africa. The sample consisted of 50 traditional healers (13 females and 37 males and 50 faith healers (12 females and 38 males. They were interviewed on local terminology, clinical manifestations, causes, curability, and treatment for diabetes, help-seeking behaviour of diabetes patients, and the healers’ sources of information about diabetes. Results indicate that all healers were familiar with “diabetes”, however, not all of them had seen patients suffering from diabetes. The perceived causes of diabetes by both traditional and faith healers could be divided into (1 diet (especially too much of sugar, (2 heredity, (3 supernatural, and (4 psychological causes. Most traditional healers (92% and faith healers (90% indicated that diabetes is curable. Treatments used by the healers in this study included the use of prayer, diet, and herbs. The authors conclude that the concepts and treatment modalities for diabetes among traditional and faith healers should be taken note of by health workers while developing health education programmes in the Province.

    Parasitic gastrointestinal infections are one of the most important health problems in the developing countries, which lead to the onset of intestinal disease particularly diarrhoea. Due to the particular geographic situation in the Mazandaran province, individuals are infected with various intestinal parasites. The aim of this study was to determine the prevalence rate of enteropathogenic parasites in the patients with gastroenteritis living at the east of Mazandaran province (Sari, Nekah and Joybar cities), northern Iran. This descriptive study was carried out from September 2009 to March 2010. Faecal samples were collected by randomized cluster method from 962 patients with gastroenteritis who were refered to the Health Service Centers of Sari, Neka and Joybar cities. All data about the patients were recorded in questionnaire. Stool specimens were examined by direct wet mounting, formolether concentration, and Ziehl-Neelsen acid fast stain and Auramin Phenol fluorescence (APF) method for the investigation of Cryptosporidium and Isospora. Prevalence of intestinal parasites and their relationship with gender, age, and season were investigated, and the obtained data were analyzed with χ² test using the SPSS software (16.0). Out of 962 patients with gastroenteritis, overall infection was 9.1%; Giardia lamblia (4.1%) with the highest and Enterobius vermicularis (0.2%) with the lowest prevalence rate. Prevalence rate of other parasites were as follow: Cryptosporidium, 0.1%; Entamoeba histolytica, 0.1%; Chilomastix mesnili, 0.1%; Entamoeba coli, 1.2%; Blastocytis hominis, 1.8%; Trichostrongylus spp., 0.4% and Hymenolepis nana, 0.9%. Findings showed that Giardia is the most common cause of intestinal infection at the east of Mazandaran province, and could be defined as the most important parasitic agent of gastroenteritis. On the other hand, infection with enteropathogenic parasites as compared with the previous reports showed significant decline, which reveals the

    By using the EOS/MODIS NPP data of remote sensing biogeochemical model ( BI-OME-BGC) , this paper analyzed the spatiotemporal variations of vegetations carbon fixation quantity in the reforested croplands of Shaanxi Province, China in 2000-2010, and estimated the service values of the vegetation carbon fixation and oxygen release, according to the specifications for the assessment of forest ecosystem services in China. From 2000 to 2010, the estimated carbon fixation density in the reforested croplands was averagely 299 g · m-2 · a-1. As compared to the year 2000, the amount of carbon fixation in the reforested croplands in 2010 increased by 5. 37×106 t · a-1 , and the carbon fixation value totaled 1.401 billions Yuan, accounting for 50. 4% of the increment value of the carbon fixation in the Province, while the area of the reforested croplands only occupied 38. 5% of the total area of the Province. The amount of oxygen release in the reforested croplands increased by 1.43×107 t · a-1 , and the oxygen release value totaled 5.053 billions Yuan. In the reforested croplands, the carbon fixation density had a slow increase (though with fluctuation) , but the increasing trend was more significant and the increment was higher than that in the perimeter zones. The area where the carbon fixation density increased occupied 99. 8% of the reforested cropland area, while the area where the carbon fixation density decreased only occupied 0. 2%. The proportion of the total area with low carbon fixation density was decreasing, while that with medium and high carbon densities was increasing. In the reforested cropland area, the carbon fixation density in the main land-use types had an obvious increasing trend, while that in different steep lands showed different increasing trend, being most significant (P25° lands. It was suggested that with the implementation of the project of reforesting cultivated land, vegetation coverage improved gradually, and significant benefits

    Neospora caninum, an obligate intracellular protozoan parasite, is the causative agent of neosporosis, recognized as a major cause of bovine abortion around the world. Thailand is a developing agricultural country located in Southeast Asia. Livestock developments particularly in dairy cows of this country have been hampered by low productivity including milk and slow growth rate due to the impact of many pathogens including N. caninum. Currently, there is no effective method for control of neosporosis since there is less information regarding current status of infections. The objective of this study was to investigate the seroprevalence of neosporosis in dairy cows of the northern part of Thailand. During 2006-2007, the sera of 642 cows from 42 small farm holders with the top three highest consensus of dairy farms in the northern provinces, such as Chiang Rai, Chiang Mai and Lumpang were collected and performed tests. Antibodies to N. caninum were assayed by enzyme-linked immunosorbent assay (ELISA) with recombinant N. caninum surface antigen 1 (NcSAG1) and indirect fluorescent antibody test (IFAT). The overall prevalence of N. caninum infection in this study was 46.9% (301/642) by ELISA and 34.3% (220/642) by IFAT.

    Soil-transmitted helminth (STH) infections are responsible for significant burden of morbidity and mortality worldwide. Consumption of raw vegetables without proper washing is one of the major routes of such infections. We evaluate the prevalence of STH contamination in commonly used vegetables in Mazandaran province, northern Iran. A total of 772 fresh raw vegetables were obtained from retail markets. Each sample was divided into two groups. One group was used as the unwashed sample and the second group was washed with standard washing procedures. Then, samples were examined for helminth eggs by using standard methods. Data analysis was performed using SPSS20. The overall prevalence of STHs was 14.89% (115/772). The rate of STH contamination was significantly higher in warm seasons (20.5%, 79/386) than in cold seasons (9.32%, 36/386) among the unwashed vegetables (OR=2.50; CI 95%=1.64-3.8; Pvegetables than root vegetables (OR=1.67; CI 95%=1.09-2.55; Pvegetables were as follows: Ascaris lumbricoides (3.36%), Trichuris trichiura (2.2%), hookworms (2.9%), Toxocara spp. (1.68%), Trichostrongylus spp. (1.55), Taenia sp. (0.9%) and Hymenolepis nana (2.2%). The results of the present study emphasized that vegetables are potential risk factor for transmission of helminth infection to human in northern Iran. It is necessary that health authorities trained the consumers to proper and standard washing of vegetables before consumption. Copyright © 2016 Elsevier B.V. All rights reserved.

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    The red beds of the northern Heyuan Basin (Guangdong Province, China) are more than 4,000 m thick.Based on the lithological characters, in ascending order these beds are divided into the Dafeng Formation, Zhutian Formation, and Zhenshui Formation of the Nanxiong Group, Shanghu Formation and Danxia Formation. The Nanxiong Group with relatively mature coarse clastic rocks attains about 2 940 m in thickness. The Dafeng Formation is 837 m thick,consisting of conglomerates and sandy conglomerates; the Zhutian Formation, which is 1,200 m thick, consists of purplish red sandstone with gravels, poorly sorted sandstone, feldspathic quartzose sandstone banded granular conglomerate,siltstone, and sandy mudstone. The Zhutian Formation is rich in calcareous concretions. Heyuannia (Oviraptoridae) and turtle fossils were found in this formation. The Zhenshui Formation deposited to a thickness of 900 m consists of coarse sediments, including granular conglomerate, and gravelly sandstone with well developed cross-beddings; the Shanghu Formation, which is 820 m thick, consists of purplish red granular conglomerate coarse sandstone intercalated with fine siltstone; the Danxia Formation characterized by the Danxia landform is composed of coarse clastic gravels and sandy gravels. The lower part of the Nanxiong Group whence dinosaur eggs and derived oviraptorosaurs come, belongs to the Late Cretaceous. No fossils are found in the Shanghu Formation or the Danxia Formation, but their stratigraphic order of superposition on the Nanxiong Group clearly shows their younger age.

    Quaternary volcanic rocks often coexist with loess,as observed in the same geologic sections in the Shandong Peninsula and northern parts of Jiangsu and Anhui provinces.The development age of Shandong loess in close to that in the middle reaches of the Yellow River.Loess strata are of synchronous implication in the loess belt of North China.So the ages of volcanic activities can be es-timated approximately from the stratigraphic relations between loess layers and volcanic rocks.The re-sults of dating of the Quaternary volcanic rocks,baked layers and the TL dates of loess samples sug-gest that the Quaternary volcanic activity can be divided into 4 stages in the region studied,with the ages being 1.15-1.03,0.86-0.72,0.55-0.33 and 0.02 Ma B.P.respectively .The occurrence of tephra in the Shandong loess sections is possible due to multiple episodes of volcanism during the Quaternary time.

    The aim of this study was to identify the main weed communities in Al-Jouf province in northern Saudi Arabia. Moreover, the composition and diversity of these communities were studied in relation to soil variables and crop type. Some 54 stands representing olive orchards, date palm orchards, wheat crop and watermelon crop were studied, using ten quadrats (1 × 1 m) per stand. A total of 71 species belonging to 22 families and 61 genera were observed. The classification of vegetation using the Two Way Indicator Species Analysis (TWINSPAN) resulted in the recognition of four vegetation groups representing wheat crop, orchards in winter season, orchards in summer season and watermelon crop. These results suggested the importance of both crop and season for the formation of weed community. Detrended Correspondence Analysis (DCA) showed that these groups are clearly distinguished by the first two DCA axes. The species richness was higher in both olive and date palm orchards than in wheat and watermelon crops. This pattern of species richness could be related to farm management practices and habitat micro-heterogeneity. Soil electrical conductivity, organic carbon and soil texture showed significant correlations with species richness and the cover values of some dominant species, suggesting the significant role of soil characteristics in weed community structure and diversity.

    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.

    Vertical electrical resistivity soundings (VES) were carried out over four major dykes of Nandurbar district in the northern Deccan Volcanic Province (DVP) of Maharashtra to investigate the subsurface geological conditions, with an aim of identifying zones with groundwater resource potential. Dykes can act as pathways or barrier to the groundwater flow depending upon the intensity of fracturing in the dyke rock. Whether the dykes act as water conduits or as barriers depends on their structure, location and orientation with respect to the groundwater flow. The Nandurbar district is known for occurrence of dykes and dyke swarms. A total of 33 dykes were demarcated in the study region and four major dykes (D4, D5, D6, and D7) from these were chosen for detailed VES studies. Data were acquired over these four dykes during pre-monsoon and post-monsoon periods to observe the seasonal variation in groundwater movement. These studies revealed changes in field characters, their attitudes, thickness and structure of the dykes. Longitudinal geoelectrical sections along these dykes demonstrated carrier as well as barrier stretches which identified potential aquifers up to depths of 25–30m below which hard and compact rock exists. These studies also indicated that dykes with sufficient width, length and favourable hydrogeological structure form potential aquifers for the occurrence and movement of groundwater in the study area.

    Located at the juncture of Shanxi and Shaanxi provinces, the transportation network has been devel- oped in the Hancheng coal mine area. There are many heavy industries in this area because it has abundant natru- al resources. Enviormnetal pollution is serious and typical in this area, and the residents is anxious about their health. The aim of this paper is to examine the environmental perception and adjustment of residents livng in the coal mine by interviews and 454 valid questionnaires. The influencing factors of environmental perception and adjustment are analyzed through Chi-Square tests, rank sum test and path analysis. The results are obtained as follows: (1) Most of residents rarely take action to protect their rights. Residents preferred to make a call to re- quest improving environment. Some 90.1% of the residents hope that their children can get away from this area due to the environmental pollution. (2) The air pollution adjustments do not vary sigificantly with gender. It is the same with water pollution and noise pollution adjustment. The water pollution and noise pollution adjust- ments are sigificantly different among age groups. (3) The relation between perception and adjustment: "tolerat- ing the extent of pollution for economic or employment reasons" has negtive effects on "moving attitude" and "appeal attitude". "Assessment of environmental pollution" has positive effects on "appeal attitude", "com- plaint to colleagues" and "avoiding being at home". "Appeal attitude" and "complaint to colleagues" have posi- tive effects on "protecting resident' s rights activity". "Satisfaction of environmental protection to the local gov- ernment" has negtive effects on "protecting residents' rights activity".%陕西省韩城矿区煤炭资源丰富,但环境污染非常严重,当地居民对此深感焦虑。本研究的目的是了解不同属性的居民对环境污染的调适行为

    The Jianchaling gold deposit in Shaanxi province, China, is located to the south of the Mianlue suture zone. The ore bodies were controlled by fault F1-45 and the secondary faults. The hydrothermal ore-forming processes can be divided into three stages according to the mineral assemblages and the crosscutting relationships of the veinlets as follows: (I) quartz-pyrite-dolomite vein with poor sulfides which was strongly deformed in a compressional or transcompressional setting; (II) quartz-polymetallic sulfides vein, characterized by large amount of fuchsite; and (III) dolomite-calcite-quartz-orpiment-realgar veinlets. The δ18OW and δD values of early stage fluids range from 7.5‰ to 21.1‰, with an average of 13.3‰, and from-85‰to-70‰, with an average of-77‰, respectively;while theδ18OW of late stage fluids range from 2.5‰to 7.7‰, with an average of 6.5‰, and the average value of δD is-81‰. This H-O isotopic signature suggests a shift from metamorphic water towards meteoric water. δ13CCO2 values of the ore-forming fluid range from -2.4‰ to 2.6‰ in stage I, from -1.9‰ to 0.4‰ in stage II, and from -5.0‰ to 1.6‰ in stage III, respectively, indicating that the ore-forming fluids were derived from metamorphic devolatilisation of carbonate strata. The δ34S values of the Jianchaling ores (10.0‰~14.3‰) suggest that the sulfur was mainly sourced from evaporation strata. The Pb isotope ratios of the ores have less radiogenic Pb isotope than the host rocks, and suggest that the ore-forming fluids, which interacted with the wallrocks to form ores, must have been sourced from a depleted mantle or a depleted subducting oceanic slab. In combination with the H, O, C, S and Pb geochemical signatures of the mineral systems, we argue that the initial ore-forming fluid is mainly metamorphic extracted from the dehydration of the wall rocks, and the ore-forming materials might have derived mainly from the wall rocks with mantle input.%陕西省

    陕西地处我国西北经济欠发达地区,发展普惠金融对平衡城乡经济发展、促进经济结构转型升级的意义重大。本文在借鉴国内外学者相关研究的基础上,首次使用涉农贷款、下岗失业人员贷款等普惠金融发展指标,并将其综合为个人普惠金融发展指数、产业普惠金融发展指数和农村普惠金融发展指数。在此基础上,借助协整理论和VAR模型研究普惠金融发展对平衡城乡经济发展、减小经济波动的效应。实证研究结果显示:个人普惠金融发展指数提高对于缩小城乡收入差距具有积极作用,而且两者互为因果关系,其效应的显现也不存在时滞性;农村普惠金融发展指数的提高对于减小经济波动并无显著作用,产业普惠金融发展指数的提高有助于减小经济的波动性,但存在3个季度的滞后期。在发展普惠金融方面,建议通过创新普惠金融产品,提升金融服务的覆盖面,不断提升普会金融发展的深度和广度。同时,建立普惠金融发展监测体系,并加强金融和财政政策的支持,持续提升政策的着力点和有效性。%Shaanxi province is located in the northwest of China where the economy is less developed, therefore, developing the inclusive finance is of great significance to balance the urban and rural economic development and promote the transformation and up-grading of the economic structure. On the basis of the related research of scholars at home and abroad for reference, the paper for the first time uses the development indicators of the inclusive finance such as loans related to agriculture and loans for the unemployed, and synthesizes them as the development index of individual, industrial and rural inclusive finance. And then, using the cointegration theory and VAR model, the paper studies the effect of the development of the inclusive finance on balancing the urban and rural eco

    Full Text Available The objective of this study was to determine the species composition of ixodid ticks infesting domestic dogs in the northwestern region of the Northern Cape Province of South Africa and in Namibia. Ticks were collected from February 2008 to January 2009 from dogs presented for a variety of reasons at a veterinary clinic in the Northern Cape Province and at 3 clinics in Namibia. The ticks collected at each place were pooled separately for each month at each locality. Eleven ixodid tick species were collected from dogs in the Northern Cape Province and new locality records for Haemaphysalis colesbergensis and Ixodes rubicundus, new locality and host records for Hyalomma glabrum, and a new host record for Rhipicephalus neumanni are reported. Six tick species were collected from dogs at the 3 clinics in Namibia. The most numerous species on dogs in both countries was R. sanguineus. The present results increase the total number of ixodid tick species collected from dogs in South Africa from 25 to 28.

    This exploratory analysis of factors associated with Chinese women's fertility desires uses data on married women between the ages of 18 and 35 who live in Shaanxi Province, China. Analyses using an economic framework found that both rural and urban couples who intended to sign, or who had already signed, the one-child certificate reported wanting significantly fewer children. However, in rural areas (where 80 per cent of the provincial population lives), education level, living arrangements, participation in an arranged marriage, attitudes regarding the ideal age for marriage, and knowledge of the reasons for the government's fertility policies appear to play a relatively larger role in shaping fertility preferences.

    Energy shortage (e.g., shortage of coal, oil, gas, and electricity), "blackouts", and a severe icing and snow disaster occurring across a large part of South China in the beginning of 2008, made issues regarding China' s regional energy security more prominent. Regional energy security is an extremely important issue in China' s development and cannot be ignored and should be addressed. There are few studies on regional energy security of China. To meet the need for regional development, this study was focused on regional differences in energy security of China based on clarifying the concept of regional energy security, examining differences between regional energy security and national energy security, and reviewing energy security indicators in the literature. Guangdong Province, representing the energy input area, and Shaanxi Province, representing the energy output area, were chosen to be investigated. An evaluation index system for regional energy security of China was built, which was applied to estimate trends in evolution of regional energy security in China from 1995 through 2008. Conclusions are drawn as follows. Firstly, from 1995 to 2008, the stability of energy supply in Shaanxi was continuously improving, while Guangdong became worse. Obviously, the stability of energy supply in Shaanxi was much better than Guangdong. Secondly, usage security trends in Shaanxi first increased and then decreased, whereas Guangdong showed a steady development trend with a prominent advantage in terms of usage security. Thirdly, dependence on foreign coal, the production/consumption (P/C) ratio of coal and transport risk index of energy were the key constraints to the stability of energy supply, while the amount of energy used per unit of economic activity (Mtce/GDP) and the amount of carbon dioxide emissions from energy consumption per unit GDP are the key influencing factors of usage security. Diversification of primary energy consumption would

    The northern region of Guangdong Province, China, has suffered from the extensive mining/milling of uranium for several decades. In this study, surface waters in the region were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES) for the concentrations of uranium (U), thorium (Th), and non-radioactive metals (Fe, Mn, Mg, Li, Co, Cu, Ni, and Zn). Results showed highly elevated concentrations of the studied radionuclides and metals in the discharged effluents and the tailing seepage of the U mining/milling sites. Radionuclide and heavy metal concentrations were also observed to be overall enhanced in the recipient stream that collected the discharged effluents from the industrial site, compared to the control streams, and rivers with no impacts from the U mining/milling sites. They displayed significant spatial variations and a general decrease downstream away from upper point-source discharges of the industrial site. In addition, obvious positive correlations were found between U and Th, Fe, Zn, Li, and Co (R{sup 2} > 0.93, n = 28) in the studied water samples, which suggest for an identical source and transport pathway of these elements. In combination with present surface water chemistry and chemical compositions of uraniferous minerals, the elevation of the analyzed elements in the recipient stream most likely arose from the liquid effluents, processing water, and acid drainage from the U mining/milling facilities. The dispersion of radionuclides and hazardous metals is actually limited to a small area at present, but some potential risk should not be negligible for local ecosystem. The results indicate that environmental remediation work is required to implement and future cleaner production technology should be oriented to avoid wide dispersion of radioactivity and non-radioactive hazards in U mining/milling sites.

    From the view of resource economics, the quality of human resources, that is the manpower capital, is a significant factor that impacts the labor efficiency. As one of the most important human resources since the reform and opening up, rural surplus labor has made historic contribution for industrialization and urbanization of China. However, some practical problems such as low quality human capital and irrational structure also exist. At present, rural surplus labor is the focus point for sustainable development and the key point for facilitating the urbanization process and new rural reconstruction. Essentially the question of human capital not only relates to individual survival and development, but also influences the sustainable development of Chinese society. Since the 1980s, this question has aroused more and more attention from governments of different levels as well as the academic circle. This paper has estimated the scale of rural surplus labor in Shaanxi with proportion method of cultivated land labor and studied the status quo of human capital quality. The results show that there mainly exist the following problems: 1) Lots of rural surplus labors exist in Shaanxi and the total amount is increasing; 2) The quality of human capital of rural surplus labor is relatively low due to the limitation of education degree and labor skills; 3) The human capital structure is not rational. Therefore, increasing educational investment of human capital for rural surplus labor is not only the main content reflecting social justice and harmonious development, but also a fundamental strategy for transforming the unbalanced economic situation formed in the past years in urban and rural areas of Shaanxi and even the whole country, accelerating the transition of surplus labor in Shaanxi, promoting industrialization and urbanization process, and further realizing sustainable and healthy economic development in Shaanxi and even the country in the future.

    Full Text Available In recent years, the worsening of the quality of the air has urged more people to attach great importance to circular economy. Shaanxi, abundant in natural resources, maintained the GDP growth rate of 14.9% during the period of the twelfth five-year plan. However, the fast economic growth under the extensive traditional economic growth mode renders Shaanxi inadequate in resources supply and noticeably worse in ecological environment issues. With the method of the IPAT equation, this paper quantitatively analyzes the developmental stage and the developmental level of the circular economy of Shaanxi to cover the shortage of the previous studies having only been focused on the policy study and the practice mode. The result shows that Shaanxi is in the intermediate stage of circular economy and the advanced stage has an apparent advantage over the intermediate one by comparing their energy consumption and solid pollutant discharge. The development experience of Shaanxi, a typical province of China, has guidance and reference significance to China and other developing countries.

    Full Text Available In recent decades, climate change has affected vegetation growth in terrestrial ecosystems. We investigated spatial and temporal patterns of vegetation cover on the Loess Plateau’s Shaanxi-Gansu-Ningxia region in central China using MODIS-NDVI data for 2000–2014. We examined the roles of regional climate change and human activities in vegetation restoration, particularly from 1999 when conversion of sloping farmland to forestland or grassland began under the national Grain-for-Green program. Our results indicated a general upward trend in average NDVI values in the study area. The region’s annual growth rate greatly exceeded those of the Three-North Shelter Forest, the upper reaches of the Yellow River, the Qinling–Daba Mountains, and the Three-River Headwater region. The green vegetation zone has been annually extending from the southeast toward the northwest, with about 97.4% of the region evidencing an upward trend in vegetation cover. The NDVI trend and fluctuation characteristics indicate the occurrence of vegetation restoration in the study region, with gradual vegetation stabilization associated with 15 years of ecological engineering projects. Under favorable climatic conditions, increasing local vegetation cover is primarily attributable to ecosystem reconstruction projects. However, our findings indicate a growing risk of vegetation degradation in the northern part of Shaanxi Province as a result of energy production facilities and chemical industry infrastructure, and increasing exploitation of mineral resources.

    Spauligodon timbavatiensis n. sp. (Nematoda: Pharyngodonidae) from the large intestine of Pachydactylus turneri (Sauria: Gekkonidae) in the Northern Province (RSA) is described and illustrated. It is the fifth species in the Ethiopian region, the others being Spauligodon smithi from Pachydactylus bibronii and Spauligodon petersi from Mabuya sulcata, both in the Northern Cape Province, South Africa, Spauligodon morgani from Mabuya striata in Malawi, and Spauligodon dimorpha from Chamaeleo pardalis in Madagascar. The males of the new species differ from S. smithi in that the adcloacal papillae are single (bifid in S. smithi), from S. petersi in the presence of a spicule and having narrow lateral alae (wide and triangular in S. petersi) and from S. dimorpha and S. morgani in having a spicule. Furthermore, S. timbavatiensis differs from S. morgani in lacking spines on the tail. The females of the new species have a long tail and truncated egg ends as opposed to the short, spiky tail and pointed eggs of S. morgani, a spiny tail and truncated eggs as opposed to the smooth tail and pointed eggs of S. petersi and a longer oesophagus than S. smithi. Furthermore, the females of S. dimorpha and S. morgani are much larger than those of S. timbavatiensis. In addition, the excretory pore opens behind the posterior end of the oesophageal bulb in the new species, while in S. smithi and S. dimorpha it opens at the level of the end of the oesophageal bulb.

    Net Primary Productivity (NPP) is one of the important biophysical variables of vegetation activity, and it plays an important role in studying global carbon cycle, carbon source and sink of ecosystem, and spatial and temporal distribution of CO2. Remote sensing can provide broad view quickly, timely and multi-temporally, which makes it an attractive and powerful tool for studying ecosystem primary productivity, at scales ranging from local to global. This paper aims to use Moderate Resolution Imaging Spectroradiometer (MODIS) data to estimate and analyze spatial and temporal distribution of NPP of the northern Hebei Province in 2001 based on Carnegie-Ames-Stanford Approach (CASA) model.The spatial distribution of Absorbed Photosynthetically Active Radiation (APAR) of vegetation and light use efficiency in three geographical subregions, that is, Bashang Plateau Region, Basin Region in the northwestern Hebei Province and Yanshan Mountainous Region in the Northern Hebei Province were analyzed, and total NPP spatial distribution of the study area in 2001 was discussed. Based on 16-day MODIS Fraction of Photosynthetically Active Radiation absorbed by vegetation (FPAR) product, 16-day composite NPP dynamics were calculated using CASA model; the seasonal dyamics of vegetation NPP in three subregions were also analyzed. Result reveals that the total NPP of the study area in 2001 was 25.1877×106 gC/(m2·a), and NPP in 2001 ranged from 2 to 608 gC/(m2·a), with an average of 337.516 gC/(m2·a). NPP of the study area in 2001 accumulated mainly from May to September (DOY 129-272), high NPP values appeared from June to August (DOY 177-204), and the maximum NPP appeared from late July to mid-August (DOY 209-224).

    Carbon Capture Utilisation and Storage (CCUS) is a key technology to reduce China's carbon emissions, while satisfying its increasing demand for electricity and chemical products, and its continuous reliance on coal. Preliminary work on CCUS in China has focused on CCUS in the power sector. However, capture in the power sector is technically challenging, energy-intensive and expensive. Capture can be implemented at lower cost at large point sources of concentrated CO2, such as in ammonia and methanol plants, coal-to-liquids facilities and hydrogen production processes. China has a large industrial base in these sectors, resulting in a significant CO2 emission reduction potential through CCUS. In recent years China has seen the development of Enhanced Oil Recovery (EOR) activities. EOR injects CO2 in oil reservoirs to enhance production and prolong the life of the reservoir. EOR is widely applied in the United States and Canada and is in development in the Middle East. China has a large EOR potential and an EOR industry is emerging. CO2 from nearby high-concentration point sources has a value for EOR operations. This value can be used to develop early cost-effective CCUS projects involving industries where capture costs are relatively low. To date a number of separate preliminary pilots for the capture and storage of CO2 have been and are being undertaken in China. However, none of these pilots succeed in cost-effectively establishing a fully integrated CCUS chain. Early demonstration of cost-effective CCUS potential in selected sectors can significantly advance CCUS development in China in selected industries, in time crossing over into other sectors, including power, as the technology and policy conditions mature. Against this background, this international collaboration project identified cost-effective integrated CCUS opportunities in Shaanxi and developed recommendations to advance the implementation of these opportunities.

    To overcome shortcoming of current research on relative roles of climate change and human activities in desertification process, we put forward a vegetation-climate spatio-temporal relationship statistical model. Based on this model, we quantitatively discriminated the relative roles of climate change and human activities in the desertifi- cation process in Yulin, Shaanxi Province from 1986 to 2000 on grid scale. Results showed that desertification devel- opment occurred mainly in the southern hilly and gully area of Yulin whereas desertification reversion took place in the northern sand and marsh area. The spatial pattern was especially evident and had no significant change in the study period. From the first time section (1986--1990) to the second (1991--1995), the desertification process was developing as a whole, and human activities' roles were always overwhelmingly dominant in the desertification de- velopment district and the desertification reversion district (they were 98. 7 % and 101.4 % respectively), but the role of climate change was extremely slight. From the second time section (1991-1995) to the third time section (1996--2000), the desertification process reached a stable state, and the role of climate change was nearly equiva- lent to that of human activities in the desertification development district (they were 46.2% and 53.8% separate- ly), yet the role of human activities came up to 119.0% in the desertification reversion district, while the role of climate change amounted to --19.0%. In addition, the relative roles of climate change and human activities pos- sessed great spatial heterogeneity. The conclusion rather coincides with the qualitative analysis in many literatures, it indicates that this method has certain rationality and can be utilized as a reference for desertification monitoring and research in other areas.%针对已有研究的不足,提出一个集成时序和空间两方面特征的植被-气候时

    Crimean-Congo hemorrhagic fever virus threatens human health. Exposure of the infected tick is a strong risk factor for human disease. In this study, the hard ticks collected from a variety of mammalian species (cattle, sheep, goat, and buffalo) and a turtle in either coastal or inland Black Sea region of Turkey were surveyed for the presence of antigen from Crimean-Congo hemorrhagic fever virus (CCHFV). CCHFV antigen was found in 46 of 421 tick pools (10.92%). Positivity rates for the provinces varied and were as follows: Samsun 33.87%, Ordu 4.34%, Giresun 8.86%, Sinop 6.09%, Amasya 7.40%, Tokat 5.08%, and Sivas 8.06%. CCHFV antigen was detected in seven of 11 tick species tested. These results suggest that these hard ticks may act as a reservoir for CCHFV in northern Turkey.

    Full Text Available The mainly meta-volcano-sedimentary Vila Nova Group and associated granites constitute separate belts, which formpart of a large paleoproterozoic (mainly rhyacian province in the Guyana Shield of which northern Brazil forms a part, andthe West African Craton. In Brazil the southwestern Serra do Ipitinga and Serra Tumucumaque-Serra do Navio belts have noobvious geometrical extensions in the Guyanas or Venezuela, and may represent deposits formed at penecontemporaneouspassive continental margins and ocean floor spreading centres. To the Northeast the Serra Lombarda-Tartarugalzinho andOiapoque belts are continuations of Guianese belts. In the former the igneous rocks have geochemical characteristics ofsuprasubduction environments. Belts in the Guyana Shield and West African Craton have many similar features. Themegaprovince evolved in a number of stages, which may have started at about 2.3 Ga, and continued with diminished activityafter 2.11 Ga. Both major juvenile additions and (possibly minor reworking of earlier crust contributed to the growth of theprovince. The major transcurrent deformation, responsible for the present structure of the belts, probably occurred duringthe later stages of evolution of the province, but metamorphism and deformation are registered even in the oldest rocks.

    The influential systems, upper jet, stream field and convective vorticity vector for a heavy rainstorm impacted southwest vortex in northeast part of Sichuan and southeast part of Shaanxi on 16 - 19 July 2010 are diagnostically analyzed based on the conventional observation data, NCEP reanalysis data, automatic station data, satellite cloud image and radar data. The results show that the stable saddle field provides the background for the occurring and developing of the southwest vortex and northeastward moving. A deep trough in north and southwest vortex in south pattern is important reason for the southwest vortex to maintain. The division area, which is formed by between the northeast airflow on south side of the northeast-southwest direction upper jet center and the southeast airflow on northeast side of the South Asia high, offers the dynamic condition for ascending motion. The south warm-wet airflow caused by the strong pressure gradient force between typhoon and Subtropical High supplies the abundant water vapor for the heavy rainstorm area. The precipitation intensity caused by southwest vortex during the developing phase is significantly greater than decaying phase. The heavy rainstorm locates in the coincidence area of the vertical component of convective vorticity vector and atmospheric column cloud water.%利用常规观测资料、NCEP再分析资料、自动站资料、卫星云图和雷达资料,对2010年7月16-19日西南涡东北移造成川陕大暴雨天气过程的影响系统、高空急流、流场和对流涡度矢量等方面进行了诊断分析,探讨了大暴雨的发生、发展机制及其天气学特征和物理量特征.结果表明,鞍形场的稳定存在为西南低涡的发生、发展及其东北移提供了环流背景,“北槽南涡”形势是西南涡长时间维持的原因.东北一西南急流中心南侧的东北气流和南亚高压东北侧的东南气流构成的分流区对四川东北部和陕南大暴雨的产生

    Pollen and diatom analyses of a radiocarbon dated lacustrine section in the temperate Andean region of Argentina (Rahue, Province Neuquen) suggest interglacial type climatic conditions between 27,000 and 33,000 yr B.P., with environments that resemble the modern conditions at the locality. This finding correlates with a woodland record from central Chile, interpreted as reflecting conditions substantially warmer and drier prior to 27,000 yr B.P. than during the following full-glacial period. It also appears to relate to the global paleoclimatic scheme derived from deep-sea records, suggesting interhemispheric synchroneity of such broad-scale palaeoclimatic phases. ?? 1986.

    Experiments were carried out in 1994 - 1998 to study crop rotation and its effects on crop water consumption characteristics of field with sandy chestnut soil in the Plateau of north Hebei Province. Five crops including spring wheat, oat, pea, flax and potato were examined. There was little difference in field water consumption among the crops during the growing season. WUE varied significantly in a range of 1. 347 - 11.177kg · ha-1· mm-1 among crops and 11.44% - 46.66% among previous crops. It was pointed out that the land equivalent ratio (LER) can be used as an index to evaluate the biological effects of crop rotation comprehensively. The 2 - 4 year crop rotation patterns with higher LER were estimated in the paper.

    Yaws and trachoma are targeted for eradication and elimination as public health problems. In trachoma-endemic populations mass administration of azithromycin can simultaneously treat yaws. We conducted a population-based prevalence survey in the five northernmost provinces of Vanuatu, where trachoma and yaws are suspected to be co-endemic. Clinical signs of trachoma were evaluated using the WHO simplified grading system, and skin examination with a serological rapid diagnostic test used to identify yaws. We enrolled 1004 households in 59 villages over 16 islands, and examined 3650 individuals of all ages for trachoma. The overall adjusted prevalence of trachomatous inflammation-follicular (TF) in 1–9 year-olds was 12.0% (95% Confidence Interval: 8.1–16.7%), and the overall adjusted prevalence of TT in those aged 15 years and greater was 0.04% (95% CI 0–0.14%). In multivariate analysis, the odds of children having TF was 2.6 (95% CI = 1.5–4.4) times higher in households with unimproved latrines, and independently associated with the number of children in the household (OR 1.3, 95% CI = 1.0–1.6 for each additional child). We examined the skin of 821 children aged 5–14 years. Two children had yaws, giving an estimated prevalence of active yaws in those aged 5–14 years of 0.2% (95% CI = 0.03–0.9%). Mass treatment with azithromycin is recommended in these provinces. Given the apparent low burden of yaws, integration of yaws and trachoma control programmes is likely to be useful and cost-effective to national programmes. PMID:28118354

    Although considerable progress has been made in the past years in management of mosquito borne diseases such as malaria, dengue, yellow fever and West Nile fever through research in biology and ecology of the vectors, these diseases are still major threats to human health. Therefore, more research is required for better management of the diseases. This investigation provides information on the composition, co-occurrence, association and affinity indices of mosquito larvae in Mazandaran Province, northern Iran. In a large scale field study, mosquito larvae were collected from 120 sentinel sites in 16 counties in Mazandaran Province, using standard 350 ml dipper. Sampling took place monthly from May to December 2014. Collected larvae were mounted on glass slides using de Faure's medium and were diagnosed using morphological characters. Totally, 19,840 larvae were collected including three genera and 16 species from 120 larval habitats, as follows: Anopheles claviger, Anopheles hyrcanus, Anopheles maculipennis s.l., Anopheles marteri, Anopheles plumbeus, Anopheles pseudopictus, Culex pipiens, Culex tritaeniorhynchus, Culex torrentium, Culex perexiguus, Culex territans, Culex mimeticus, Culex hortensis, Culiseta annulata, Culiseta longiareolata, and Culiseta morsitans. Predominant species were Cx. pipiens and An. maculipennis s.l. which show the highest co-occurrence. The pair of species An. hyrcanus/An. pseudopictus showed significant affinity and association. High co-occurrence of the predominant species Cx. pipiens and An. maculipennis s.l. in the study area is of considerable importance in terms of vector ecology. It was also revealed that An. pseudopictus/An. hyrcanus often occur sympatrically indicating their common habitat requirements. The information may be equally important when vector control measures are considered. Copyright © 2016 Elsevier B.V. All rights reserved.

    Proterozoic granitoids and metamorphic rocks in the Olary province of the Willyama block of South Australia host ore-grade amounts of U-Th-Ti and U-Fe-Ti-Th minerals. U-Pb-Th isotope analyses on zircons from all granitoids associated with the Crocker Well brannerite deposit indicate that these granitoids were intruded within a short time span, close to the 1579.2??1.5 m.y. age of the brannerite-bearing host-rock. Though the early Paleozoic Delamerian orogeny was intense in this region, the zircon isotopic systems remained unaffected; rather, the best-defined zircon chords on concordia plots show a welldefined lower intercept of 43.8??6.5 Ma, which can only be associated with early Tertiary block faulting. Pb-U-Th isotope analyses on brannerite from the Crocker Well deposit and davidite from the Mt. Victoria deposit and the Radium Hill deposit yield badly scattered and discordant apparent ages that suggest a primary age at least as old as the age of the Crocker Well granitoids, followed by a severe disturbance in the early Paleozoic. ?? 1984 Springer-Verlag.

    Full Text Available Ground beetles (Family Carabidae with more than 40,000 described species worldwide are one of the most important generalist predators in agroecosystems. Because of their habit of feeding on agricultural pests and weed seeds, in this study we tried to assess their biodiversity in agroecosystems of Azadshahr region, eastern Golestan province. Samples were collected for some main crops, using pitfall traps during 2009 and 2010 and two indices, including SIMPSON'S RECIPROCAL INDEX and Shannon-Weaver index were used to measure diversity and structure of the community. Results showed that there were a high species richness of ground beetles in this region and 24, 22, 18, 18 and 12 species were identified in rape seed, wheat, tomato, broad bean and soybean fields, respectively. Dominant species in these crops were Harpalus distinguendus Duftchmid, Agonum dorsale (Pontoppidan, Poecilus cupreus (L., Agonum dorsale (Pontoppidan, and Harpalus rufipes (De Geer, respectively. The values of Shannon and Simpson indices in these ecosystems were 2.16, 2.57, 1.81, 2.22 and 2.00, and 4.93, 10.09, 4.21, 6.16 and 6.12, respectively. The highest (7.1±0.85 and the lowest (0.45±0.12 numbers of beetles were captured in margins of rape seed and soybean fields, respectively.

    Full Text Available Background Prevention of foodborne pathogens is essential to control infectious diseases; Salmonella spp. is referred to as the most common causative agent of foodborne illnesses. Objectives The current study aimed to determine the prevalence of Salmonella enterica subsp. enterica in broiler flocks in Mazandaran province, north of Iran and find the potential risk factors including: age, size of flock, strain, season, vaccination program and use of antibiotics. Materials and Methods From March 2012 to December 2013, a total of 50 flocks were selected in slaughterhouse and 20 cloacal samples were collected from each flock. Every five samples were pooled and investigated for Salmonella spp. using polymerase chain reaction (PCR. Results Thirteen flocks out of 50 (26% were positive for Salmonella species. Chances of Salmonella spp. detection was higher in flocks with lower age (P = 0.41. Increasing flock population was associated with increased chance of Salmonella spp. isolation (P = 0.21. The risk of salmonellosis in broiler flocks was increased when no antibiotics were given to day-old chicks. There was no significant difference (P = 0.30 in the prevalence of salmonellosis among different broiler strains. Conclusions In the current study, six risk factors were assessed for Salmonella spp. contamination in broiler flocks. Some of these factors contributed to the risk of salmonellosis in broiler flocks.

    According to the Sen's Capacity Approach and the specific features of the rural households in the mountainous areas in Zhouzhi County, Shaanxi province, the paper constructs welfare metrics for the rural households. The functional activities include the land resources, household income and consumption, household residence and environment perception, community cohesion and relationships, risk management strategies. The education level of the household members, environmental policies and distribution of the family decision rights are considered as switching factors in the model. Then the paper evaluates the welfare status of the rural households with the fuzzy analysis. The results show that the general welfare of the rural households is rather low. Among the functional activities, the community cohesion and relationship, risk management strategies are high, and the other indicators are rather low. The welfare of the households participating in the Slopping Land Conversion Program is higher than those non-participants. The education can improve the welfare of the rural households, etc.%结合森的可行能力理论和陕西周至山区农户的特征,构建了农户福利指标体系,其中农户福利的功能性指标包括土地资源、家庭收入与消费、居住状况与环境感知、社区归属感与人际关系、风险策略。将家庭成员的受教育程度、自然生态政策、家庭权利分配作为转换因素,并采用模糊评价法分析了该退耕地区农户的福利状况。结果显示,周至山区农户的总体福利水平偏低:从各个功能性活动来看,农户的社区归属感和人际关系、风险策略的选择都处于较好的状态.而土地资源、家庭收入与消费、住房状况与居住环境方面的福利状况较差。同时,退耕户的福利状况高于非退耕户,教育使农户的福利状况得到改善等。

    通过对陕西贫困山区商洛市六县一区农村留守妇女的调查和对商洛市W镇若干村留守妇女婚姻状况的深度访谈,发现这里留守妇女的婚姻呈现出较高的稳定性。婚姻稳定的原因有传统婚姻观念和婚姻习俗的影响、子女亲情的促进、夫妻人格特质差异小、经济收入的增加、离婚和再婚的经济负担太重。然而,留守妇女的婚姻仍然存在或潜伏着不稳定因素。提高留守妇女婚姻的稳定性,“治本”的方法是消除丈夫外出、妻子留守的生活方式;“治标”的方法是尽可能增加夫妻团聚的机会、缩短夫妻之间的人格特质差异、排减夫妻分居所带来的负面影响。%It is found that the left-behind women’s marital status in Shangluo City still keeps a relatively high degree of stability by investigating,and interviewing the left-behind women in the six counties in the impoverished mountainous ar-eas in Shangluo City,Shaanxi province.The result of the higher marital stability is brought about by the following as-pects:the effect of traditional marital concept and marital customs;the improvement of the love between parents and chil-dren;the slight difference of husband and wife in personality;the increase in income and the economic burden of divorce and remarriage.However,the marital stability still exits some potential problems.In order to improve marriage stability of the left-behind women,the temporary solution is to reduce the husband leaving for cities to work;the permanent one is to increase the reuniting chances of husband and wife,to reduce the personal differences between couples,and to lessen the negative effects of separated couples.

    In the context of deepening and mainly completing collective forestland tenure reform of Shaanxi Province,this paper selected 500 households and made a survey on the degree of satisfaction for three types of forestland tenure confirmation,namely contracting to household,points shares regardless of mountainous forest land,and partnerships contracting,then studied the vital factors which influence the degree of satisfaction of forest farmers by using binary-class logistic regression model. The results showed that the highest degree of satisfaction for forestland tenure confirmation was the first type,followed by the second and the third. Among the influencing factors,the outstanding issue is whether the farmers hold the forest certificate, followed by how much the farmers know about forest reform policy,forestland area,number of forestland, forestry investment and so on. Finally this paper proposed that only continuously clarifying the relationship of property right strengthening policy advocacy, increasing forestry investment, deepening forest tenure reform and building a comprehensive and effective forest tenure reform safeguard mechanism, can the degree of satisfaction of the forest farmers to the reform be improved.%在陕西省全面深化集体林权制度改革,且主体改革基本完成的背景下,选取了500户农户对承包到户、分股不分山和联户承包3种不同林地确权方式的满意度进行了问卷调查,并采用二分类Logistic回归模型研究影响农户满意度的重要因素.结果表明,农户对林地承包到户的满意度最高,其次为分股不分山、联户承包.其中是否持有林权证对满意度的影响最大,其次为林改政策了解程度、林地面积、林地块数、林业投入等因素.最后提出要继续明晰林地产权,加大政策宣传力度,增加林业投入,深化林权改革,建立全面有效的林改保障机制,才能提高农户对集体林权制度改革的满意度.

    文章以陕北地区的一个著名家族---艾氏家族为研究对象,以艾氏主姓村---G 村为主要调查点,重点突出了口传记忆与家族复兴在现代化进程中家族文化构建中的重要意义。G 村人正是通过反复的口头传述,才使得祖先的名字和事迹不断的传向了后世;在传统社会中,人们通常将家族看成了一个想象的共同体,认为它的内部是公式化了的、是同一的,而现代社会中人们的家族认同行为则是多种观念与意识交锋较量的综合结果。%This paper takes Ai Lineage,a renowned one in northern Shaanxi as the research object and takes G vil-lage,in which the surname of Ai occupies the dominate position in all of the surnames,as the major survey point, highlighting the significance of oral memory and lineage revival in the family culture construction in the process of modernization. The G villagers pass the ancestor′s names and deeds from generation to generation in oral way. In the traditional society,a lineage is normally regarded as an imaginary community,and the inside of a lineage is for-mularized and homogeneous,whereas learned from the ideas of G village,the identity of people in their lineage is the comprehensive result of the clash of various conceptions and ideas in the modern society.

    In this paper, a climate-adaptation study of vernacular houses in northern Hebei Province has been conducted based on quantitative field surveys. Three typical vernacular houses with different kinds of building envelopes were selected. The field surveys included investigation on building material and construction, measurement of indoor thermal environment, infrared thermographic study of building envelopes and measurement of luminous environment. The results showed that the indoor air temperatures were below thermal comfort zone from late night till early morning and the horizontal temperature gradient was obvious. The adobe wall showed better thermal performance than the other two. As for the building layout, it is beneficial to put a storeroom on the north side of the house as a temperature buffer zone. Furthermore, due to missing insulation and the informal process of construction, significant amounts of heat escaped from building envelopes, especially from the corner of wall, ceiling and around the openings. The daylight factors on the work plan in the main rooms were accordance with design standards and the level of illuminance met the requirements of family’ s daily activities.

  12. A Systematic Regional Trend in Helium Isotopes Across the NorthernBasin and Range Province, Western North America

    An extensive study of helium isotopes in fluids collectedfrom surface springs, fumaroles and wells across the northern Basin andRange Province reveals a systematic trend of decreasing 3He/4He ratiosfrom west to east. The western margin of the Basin and Range ischaracterized by mantle-like ratios (6-8 Ra) associated with active orrecently active crustal magma systems (e.g. Coso, Long Valley, Steamboat,and the Cascade volcanic complex). Moving towards the east, the ratiosdecline systematically to a background value of ~;0.1 Ra. The regionaltrend is consistent with extensive mantle melting concentrated along thewestern margin and is coincident with an east-to-west increase in themagnitude of northwest strain. The increase in shear strain enhancescrustal permeability resulting in high vertical fluid flow rates thatpreserve the high helium isotope ratios at the surface. Superimposed onthe regional trend are "helium spikes", local anomalies in the heliumisotope composition. These "spikes" reflect either local zones of mantlemelting or locally enhanced crustal permeability. In the case of theDixie Valley hydrothermal system, it appears to be a combination ofboth.

    The Luxi-Xianrenzhang diabase dikes were emplaced into the eastern part of the Guidong composite granitoids in northern Guangdong Province at the end of the Early Cretaceous.They show tholeiitic features,enrichment in large ion lithophile elements,slight enrichment in light rare earth elements,depletion in Zr and Hf,and basically no depletion in Nb and Ta and no Eu anomaly.They are similar to intraplate basalt in terms of trace element characteristics.They have high εNd(t) values (3.6-4.9),initial 87Sr/86Sr ratios (0.70530-0.70641) and δ18O values and Dupal anomaly of Pb isotope compositions.Their Sr-Nd,Pb-Sr,Pb-Nd and Pb-Pb isotopes plot between DMM and EMⅡ,with Pb similar to EMⅡ,Nd relatively close to DMM and Sr in between.This profile suggests that the diabase dikes studied were derived from partial melting of a mantle source that had been subjected to metasomatism by fluids originated from a subduction zone under a tectonic environment of crustal extension and lithosphere thinning in the late Yanshanian.

    Rare earth element (REE) concentrations of two different types of groundwaters (high SO42- water-SW and high alkaline waterCW) from coal bearing aquifer (-400~-280 m) in Renlou coal mine, northern Anhui Province, China were measured. The results indicated that they had different REE characteristics: the total concentrations of REEs (∑REE) of SW were lower than those of CW in general although they all had heavy REEs enriched relative to light REEs. The dissolved REE inorganic species of SW included Ln3+, LnCO3+, LnSO4+,Ln(CO3)2- and Ln(SO4)2-, whereas the CW are Ln(CO3)2- and LnCO3+ dominant, and the proportions of Ln(CO3)2- increased while other species decreased with pH increasing. Combined with correlation analysis, the enrichment and fractionation of SW (low alkaline water) were considered to be affected by alkaline concentrations via affecting the types and proportons of REE inorganic species. However, the effect of alkaline concentrations to the enrichment and fractionation of REEs of CW (high alkaline water) was less important than total dissolved solids and pH, which reflected the contribution from different rocks they flowed over, different degrees of water-rock interactions and/or REE solid-liquid partition coefficients.

    Salmonella spp. are an important group of bacterial zoonotic pathogens which can cause acute food-borne diseases in humans. Pork products are the main source of salmonellosis, but the origins and transmission routes of the disease have not been clearly determined. The purpose of this study was to characterize Salmonella spp. isolated in pig production lines both from pig farms and from slaughterhouses in Chiang Mai and Lamphun provinces in northern Thailand. The study focuses on the association among serotypes, antimicrobial resistance patterns and Pulse Field Gel Electrophoresis (PFGE) patterns to investigate possible sources of infection and to provide information which could help strengthen salmonellosis control programs in the region. A total of 86 strains of Salmonella comprising five majority serotypes were identified. Antibiotic resistance to tetracycline was found to be the most prevalent (82.56%) followed by ampicillin (81.40%) and streptomycin (63.95%). Seven clusters and 28 fingerprint-patterns generated by PFGE were identified among strains recovered from various locations and at different times, providing information on associations among the strains as well as evidence of the existence of persistent strains in some areas. Study results suggest that Salmonella control programs should be implemented at slaughterhouse production lines, including surveillance to insure good hygiene practices, in addition to regular monitoring of large populations of farm animals.

    Full Text Available New human cases of tick-borne encephalitis (TBE have recently been recorded outside the recognised foci of this disease, i.e. in the province of Trento in northern Italy. In order to predict the highest risk areas for increased TBE virus activity, we have combined cross-sectional serological data, obtained from 459 domestic goats, with analysis of the autumnal cooling rate based on Moderate Resolution Imaging Spectroradiometer (MODIS land surface temperature (LST data. A significant relationship between finding antibodies against the virus in serum (seroprevalence in goats and the autumnal cooling rate was detected, indicating that the transmission intensity of the virus does not only vary spatially, but also in relation to climatic factors. Virus seroprevalence in goats was correlated with the occurrence of TBE in humans and also with the average number of forestry workers’ tick bites, demonstrating that serological screening of domestic animals, combined with an analysis of the autumnal cooling rate, can be used as early-warning predictors of TBE risk in humans.

    Groundwater is a key factor in the socio-economic development of African societies. This is particularly true for the Lake Chad Basin countries for which groundwater is the main water resource for both drinking water supply for population and agriculture, whether small or large scale. The Central African Republic (CAR) occupies a strategic place in the Lake Chad Basin since most waters feeding the different tributaries of the Chari River, which is the main water source of the Lake Chad, are originating from its territory. Indeed, the Northern CAR and particularly the Ouham Province, at the head of the whole Chad endoreic watershed, benefits from favourable rainfall conditions. Unfortunately, very little hydrological and hydrogeological information is available for this area which has never been investigated in terms of geochemical and isotope characterisation. The only available spares technical and scientific investigations over the area are dating from the 1960's. Unfortunately the Lake Chad basin has undergone strong climatological evolutions since the 1970's and hydrological information needs to be updated. The objectives of this study are to characterise groundwater from the Ouham Province in order to better appreciate the hydrogeological processes taking place in the recharge area of the Southern Lake Chad Basin. Isotope hydrology combined with geochemistry of groundwater has now proven being the best approach in under-documented territories to have a first diagnostic on the dynamics and quality of available resources. In this purpose combined hydrogeochemical and isotopic investigations (18O, 2H and 3H of the water molecule) have been launched to constrain groundwater origin, recharge processes, quality, residence time and anthropogenic fingerprint on aquifers. After two sampling campaigns it was possible to draw a general pattern of the hydrogeological and hydrochemical conditions in the region. The Ouham province is mostly composed of Precambrian

    Full Text Available The Varroa destructor mite is considered as a major pest of honey bees Apis mellifera. The rapid spread of Varroa mites among bee colonies may be due to several factors, including drifting of infested bees, movement of bee swarms, and robbing of weakened colonies. Disease spread and predisposing the infested bees to other diseases lead to high economic losses in beekeeping industries. The aim of this study was to determine the prevalence of and evaluate some managing factors in Golestan Province in Iran in 2008.According to the records of Agricultural Research Center, 80 infested beekeeping centers identified and a questionnaire consists of managing factors for each center has been designed. All data were recorded and analyzed by SPSS software to calculate χ(2 test.Among 80 apiculture centers, 72 centers (92% were infested to Varroa and hive density of 90.6% of the centers was 31-60 hives in one center (P= 0.324. All of the apiculture centers had more than 6 km distance to nearest beekeeping center (P= 0.687. Amongst bee keepers 15(93.8% had low literacy level (P= 0.479 and 26(89.7% had 5-10 years experience in beekeeping (P= 0.953.We can conclude that because of the high prevalence of the disease, the usual methods of prevention are not effective. This high prevalence emphasizes that we are very far from a solution for Varroa infestation and extra researches on mite biology, tolerance breeding, and Varroa treatment is immediately required.

    Abstract We provide the first report on the herpetological biodiversity (amphibians and reptiles) of the northern Sierra Madre Mountain Range (Cagayan and Isabela provinces), northeast Luzon Island, Philippines. New data from extensive previously unpublished surveys in the Municipalities of Gonzaga, Gattaran, Lasam, Santa Ana, and Baggao (Cagayan Province), as well as fieldwork in the Municipalities of Cabagan, San Mariano, and Palanan (Isabela Province), combined with all available historical museum records, suggest this region is quite diverse. Our new data indicate that at least 101 species are present (29 amphibians, 30 lizards, 35 snakes, two freshwater turtles, three marine turtles, and two crocodilians) and now represented with well-documented records and/or voucher specimens, confirmed in institutional biodiversity repositories. A high percentage of Philippine endemic species constitute the local fauna (approximately 70%). The results of this and other recent studies signify that the herpetological diversity of the northern Philippines is far more diverse than previously imagined. Thirty-eight percent of our recorded species are associated with unresolved taxonomic issues (suspected new species or species complexes in need of taxonomic partitioning). This suggests that despite past and present efforts to comprehensively characterize the fauna, the herpetological biodiversity of the northern Philippines is still substantially underestimated and warranting of further study.

Our new data indicate that at least 101 species are present (29 amphibians, 30 lizards, 35 snakes, two freshwater turtles, three marine turtles, and two crocodilians and now represented with well-documented records and/or voucher specimens, confirmed in institutional biodiversity repositories. A high percentage of Philippine endemic species constitute the local fauna (approximately 70%. The results of this and other recent studies signify that the herpetological diversity of the northern Philippines is far more diverse than previously imagined. Thirty-eight percent of our recorded species are associated with unresolved taxonomic issues (suspected new species or species complexes in need of taxonomic partitioning. This suggests that despite past and present efforts to comprehensively characterize the fauna, the herpetological biodiversity of the northern Philippines is still substantially underestimated and warranting of further study.

    Full Text Available In order to better understand and manage forest ecosystems, it is important to study the relationship between environmental factors and plants in these ecosystems. We investigated plant species diversity of three hardwood forest stands in the Hyrcanian forests, Sari, northern Iran. Our aim was to determine the effect of forest stand type on the diversity of plant species. One plot 150 × 150 m established at the center of each forest stand and in each plot, nine subplots 50 × 50 m were selected. Diversity values (Richness, diversity and evenness indices were measured in five sample areas 0.01 ha per 50 × 50 m quadrates by estimating cover percentage of each species. The results showed that Geophytes (43.33% had the highest life form spectrum among species. JACCARD'S similarity index revealed that the highest values exist between Parrotia-Carpinus and Carpinus stands. All herb layer species diversity indices varied significantly among different forest stands. Cover percentage significantly positively correlated with diversity indices in Parrotia-Carpinus stand. Diversity and richness indices of herb-layers plants were significantly negatively correlated with cover percentage in Fagus stand. Correlation analysis between all diversity measures and cover percentage in Carpinus stand wasn't significant. The result of the present study revealed that species diversity in temperate broad-leaved deciduous forest was significantly influenced by forest stand type

    Balamuthia mandrillaris is an opportunistic free-living amoeba that has been reported to cause cutaneous lesions and Balamuthia amoebic encephalitis. The biology and environmental distribution of B. mandrillaris is still poorly understood and isolation of this pathogen from the environment is a rare event. Previous studies have reported that the presence of B. mandrillaris in the environment in Iran may be common. However, no clinical cases have been reported so far in this country. In the present study, a survey was conducted in order to evaluate the presence of B. mandrillaris in hot-spring samples of northern Iran. A total of 66 water samples were analysed using morphological and molecular tools. Positive samples by microscopy were confirmed by performing PCR amplification of the 16S rRNA gene of B. mandrillaris. Sequencing of the positive amplicons was also performed to confirm morphological data. Two of the 66 collected water samples were positive for B. mandrillaris after morphological and molecular identification. Interestingly, both positive hot springs had low pH values and temperatures ranging from 32 °C to 42 °C. Many locals and tourists use both hot springs due to their medicinal properties and thus contact with water bodies containing the organism increases the likelihood of infection. To the best of our knowledge, this is the first report on the isolation of B. mandrillaris from hot-spring sources related to human activity. Therefore, B. mandrillaris should be considered as a possible causative agent if cases of encephalitis are suspected following immersion in hot springs in addition to Acanthamoeba and Naegleria.

    @@%The "Grain for Green Project" initiated by the governments since 1999 were the dominant contributors to the vegetation restoration in the agro-pastoral transitional zone of northern China.Climate change and human activities are responsible for the improvement and degradation to a certain degree.In order to monitor the vegetation variations and clarify the causes of rehabilitation in the Shaanxi-Gansu-Ningxia Region,this paper,based on the MODIS-NDVI and climate data during the period of 2000-2009,analyzes the main characteristics,spatial-temporal distribution and reasons of vegetation restoration,using methods of linear regression,the Hurst Exponent,standard deviation and other methods.Results are shown as follows.(1) From 2000 to 2009,the NDVl of the study area was improved progressively,with a linear tendency being 0.032/10a,faster than the growth of the Three-North Shelter Forest Program (0.007/10a) from 1982 to 2006.(2) The vegetation restoration is characterized by two fast-growing periods,with an "S-shaped" increasing curve.(3) The largest proportion of the contribution to vegetation restoration was observed in the slightly improved area,followed by the moderate and the significantly improved area; the degraded area is distributed sporadically over southern part of Ningxia Hui Autonomous Region as well as eastern Dingbian of Shaanxi province,Huanxian and Zhengyuan of Gansu province.(4)Climate change and human activities are two driving forces in vegetation restoration; moreover anthropogenic factors such as "Grain for Green Project" were the main causes leading to an increasing trend of NDVl on local scale.However,its influencing mechanism remains to be further investigated.(5) The Hurst Exponent of NDVl time series shows that the vegetation restoration was sustainable.It is expected that improvement in vegetation cover will expand to the most parts of the region.

    The mid-late Pliocene warm period (MPWP) is the most recent geologic interval when global atmospheric CO2 reached ~400 ppmv. The MPWP is of great interest to paleoclimatologists and modelers because accurate geological data would help to explain the behavior of sea level (SL) and ice sheets in a past warmer climates. Our modern industrial Earth is rapidly approaching this ominous benchmark (395.77 ppmv 6/2012). The trailing continental margin and far-field sites of western and southern Republic of South Africa (RSA) yield abundant coastal imprints of Miocene to Pleistocene seastands. Existing literature identifies zone fossils, and a few unpublished Sr-isotope ages that correlate these shoreline deposits with Pliocene highstands. Younger Pleistocene SL benchmarks provide indications of the regional tectonic stability, with MIS 5e (125 ka) deposits widely correlated along RSA coasts at about +3 m asl. Precise elevations of geomorphic, sedimentary, and biological SL indicators were measured in Western and Northern Cape Provinces of RSA with decimeter accuracy using an OmniStar differential GPS. High-resolution SL indicators (within 0.5 m of paleo-SL) include abrasion platforms (Fig 1), marine terraces, sub-, inter-, and supratidal sedimentary structures, and in situ marine invertebrates such as shallow water oysters and intertidal barnacles. The coastal geomorphic expression of the MPWP is profound. For more than 0.5 Ma, we hypothesize that high frequency (20-40 ka), low amplitude oscillations of Pliocene SL acted as a shoreline "buzz saw", laterally incising older bedrock, forming extensive planation surfaces along the coastline. We propose these broad geomorphic features are diagnostic of this prolonged interval of low amplitude but consistent SL along relatively stable, non-sediment-dominated coastlines of the world. Although currently uncorrected for post-depositional effects including GIA and dynamic topography, our PLIOMAX team (www.pliomax.org) has documented

    This report summarizes available hydrologic data for Area 62 and will aid leasing decisions, and the preparation and appraisal of environmental impact studies and mine-permit applications. Area 62 is located at the southern end of the Rocky Mountain Coal Province in parts of New Mexico and Arizona and includes approximately 9,500 square miles. Surface mining alters, at least temporarily, the environment; if the areas are unreclaimed, there can be long-term environmental consequences. The land-ownership pattern in Area 62 is complicated. The checkerboard pattern created by several types of ownership makes effective management of these lands difficult. The climate generally is semiarid with average annual precipitation ranging from 10 to 20 inches. Pinons, junipers, and grasslands cover most of the area, and much of it is used for grazing by livestock. Soils vary with landscape, differing from flood plains and hillslopes to mountain slopes. The major structural features of this area were largely developed during middle Tertiary time. The main structural features are the southern San Juan Basin and the Mogollon slope. Coal-bearing rocks are present in four Cretaceous rock units of the Mesaverde Group: the Gallup Sandstone, the Dileo Coal Member, and the Gibson Coal Member of the Crevasse Canyon Formation, and the Cleary Coal Member of the Menefee Formation. Area 62 is drained by Black Creek, the Puerco River, the Zuni River, Carrizo Wash-Largo Creek, and the Rio San Jose. Only at the headwaters of the Zuni River is the flow perennial. The streamflow-gaging station network consists of 25 stations operated for a variety of needs. Streamflow changes throughout the year with variation related directly to rainfall and snowmelt. Base flow in Area 62 is zero indicating no significant ground-water discharge. Mountainous areas contribute the highest mean annual runoff of 1.0 inch. Very few water-quality data are available for the surface-water stations. Of the nine surface

    New analyses of siderophile-lithophile elements and Sr-Nd isotopes in the Permian basalts and picrites from northern Vietnam, the southernmost occurrence of the Emeishan flood basalt province, together with previously published data, are used to address the question of whether any meaningful correlation between these elements and isotopes exists at a province scale. The available data show that negative correlations between εNd, (87Sr/86Sr)i and mantle-normalized (Nb/Th)n are present in the basalts but not in the associated picrites. This indicates that crustal contamination is negligible in the picrites but significant in some of the basalts. The picrites and basalts from the entire province show negative correlations between (Rh/Ru)n, (Pt/Ru)n, (Pd/Ru)n and Mg-number. This indicates that Ru behaves compatibly whereas Rh, Pt and Pd behave incompatibly during magma differentiation. The incompatible behavior of Rh in natural basaltic systems is also supported by the fact that (Pt/Rh)n remains constant with decreasing Mg-number in the lavas. Depletions of Pd and Pt, and to a lesser degree Cu, in some basaltic samples characterized by relatively low εNd and (Nb/Th)n support the notion that sulfide saturation in the magmas was triggered by a combination of siliceous crustal contamination and addition of external sulfur. Within the entire flood basalt province only the picrites from Song Da, northern Vietnam show clear depletion in Ir relative to Ru. These picrites are also characterized higher Al2O3/TiO2 and lower mantle-normalized La/Yb (0.2-2.4) than those from elsewhere in the province, possibly due to the involvement of an Ir-depleted, fertile mantle component in magma generation at this location.

    We studied the biomass and its allocation in natural secondary forests, as well as the amounts, accumulation and distribution of nutrient elements (N, P, K, Ca and Mg) in sample plots established in the Loess Plateau in Shanxi Province, northern China. The results show that biomass in natural secondary forests amounted to 36.09 t/hm2,. of which the tree layer accounted for 46%, the shrub layer for 29%, the herb layer for 13% and the litter layer for 12%. The total storage of the five nutrient elements is 1089.82 kg/hm2. Nutrient storage in the tree layer is the largest, at 41%. The sequence of storage of the elements varied among different layers and is given as follows: shrub layer 31.27%, herb layer 12.55% and litter layer 15.36%. The accumulation of nutrient elements in the tree layer, ordered from high to low, is: branches > roots > stems > bark > leaves. The total storage of the five nutrient elements in the soil is 634.97 t/hm2, where the accumulation of the nutrients accounts for 95.32% (N), 99.64% (P), 99.91% (K), 99.84% (Ca) and 99.95% (Mg) of the total amounts. The accumulation coefficients of different organs in the tree layer are, from high to low: leaves > branches > roots > bark > stems. The accumulation coefficients in the different layers are listed as follows: shrub layer > tree layer > herb layer and for the elements as: N > P > Ca > K > Mg.

    Hydrogeochemical data of groundwater from the semi-confined aquifer of a coastal two-tier aquifer in Amol-Ghaemshahr plain, Mazandaran Province, Northern Iran reveal salinization of the fresh groundwater (FGW). The saline groundwater zone is oriented at an angle to both Caspian Sea coastline and groundwater flow direction and extends inland from the coastline for more than 40 km. Spearman's rank correlation coefficient matrices, factor analysis data, and values of C ratio, chloro-alkaline indices, and Na(+)/Cl(-) molar ratio indicate that the ionic load in the FGW is derived essentially from carbonic acid-aided weathering of carbonates and aluminosilicate minerals, relict connate saline water, and ion exchange reactions. Saline groundwater samples (SGWS) (n = 20) can be classified into two groups. SGWS of group 1 (n = 17) represent the saline groundwater zone below the Caspian Sea level, and salinization is attributed essentially to (1) lateral intrusion of Caspian seawater as a consequence of (a) excessive withdrawal of groundwater from closely spaced bore wells located in the eastern part of the coastal zone and (b) imbalance between recharge and discharge of the two-tier aquifer and (2) upconing of paleobrine (interfaced with FGW) along deep wells. SGWS of this group contain, on average, 7.9% of saltwater, the composition of which is similar to that of Caspian seawater. SGWS of group 2 (n = 3) belong to the saline groundwater zone encountered above the Caspian Sea level, and salinization of the groundwater representing these samples is attributed to irrigation return flow (n = 2) and inflow of saline river water (n = 1).

    Eleven populations of cereal cyst nematode (CCN) from wheat were collected in collected in Qinghai and Shaanxi Provinc, all morphologically identified as Heterodera avenae. The rDNA-US regions of the populations were amplified with the universal primers AB28 and TW81, a fragment of approximately 1 060 bp was yielded. The fragments were digested with Hinf Ⅰ , TaqⅠ , Hpa Ⅱ , Hae Ⅲ, Pst Ⅰ and Alu Ⅰ . The identical digestion patterns were obtained from CCN populations (YBT10A, HY65A, HY61B, ZHZ162B, HY5B, HHX8A, GH132A, HY92A, HY127B and DT142A) of Qinghai and which were the same species. The digestion patterns were the same between YL4A population of Shaanxi and the ones of Qinghai by Hae Ⅲ ,Hinf Ⅰ and Hpa Ⅱ. The digestion patterns of Pst I and Alu I showed that the YL4A CCN population was differed from the ones of Qinghai, because it had an extra 1 060 bp fragment. The Taq I restriction pattern of YL4A CCN population was complex. The obvious difference could be observed in the Taq I RFLP pattern, a 520 bp fragment was not presented in the Qinghai CCN populations but in the Henan populations. According to the known conclusions, the analysis results restriction profiles showed that 10 populations of Qinghai were the identical RFLP patterns of H. Avenae from China. Alu I profile of YL4A population was the same as H. Avenae from France, then digestion of YL4A population by Pst I and Taq I were different with either members of Avenae group because of its complex profiles. The Henan CCN populations were the similar as Qinghai ones except RFLP profile by Taq I , and identical with H.

    Based on determination of soil water retention curves and field moisture capacity of intact soil sam- ples of Loess and Paleosols in Luochuan County, Shaanxi Province, the study analyzed the physical soil prop- erties including soil moisture storage, holding capacity and effective moisture content. The results indicate that the water retention curves of soil samples could be described well with Van Genuchten model with the high R2 values(over 0.99). The water holding capacity of the loess samples were higher than that of the Pal- eosol samples in the range of 0 to 30 kPa, suggesting that loess performs better in water supply and storage. With increasing suction values, water supply and storage reduced with larger amplitude in low suction range and smaller amplitude in high suction range. Loess showed higher available water content, saturated water content and field holding capacity, and lower permanent wilting point than paleosol.%通过对陕西省洛川县第3—4黄土层和第3—4红色古土壤层的原状土进行水分特征曲线、田间持水量等项目的实验测定,分析计算了各层土壤的供水储水性能及有效水分含量。结果表明,洛川第3—4黄土层和第3—4红色古土壤土层的水分特征曲线与Van Genuchten模型非常符合,相关系数R2均达0.99以上,说明采用Van Genuchten模型对这4个土层的水分含量和能量之间的关系进行描述是比较准确的。0~30kPa吸力条件下,第3—4黄土层比第3—4红色古土壤层持水量高,黄土层的供水(释水)性能和储水性能强于古土壤。这4个土层随着吸力的增加,在较低吸力段供水性能和储水性能减弱幅度较大,在较高吸力段减弱幅度较小。黄土层所能容纳的有效水含量、饱和含水量与田间持水量均大于红色古土壤层,黄土层的稳定凋萎湿度一般小于红色古土壤的稳定凋萎湿度。

    1994年财税体制改革促成了此后延续至今的改革红利,但其财政分权的改革远未到位,近年来能源富集区经济发展中遇到的地方税收体系建设滞后、地方政府财政困难、提供基本公共服务能力弱等问题均与此密切相关。今后所实施新一轮改革中,财税体制改革是全面深化经济体制改革的核心之一,应重点解决资源富集区矿产资源开发收益没有得到合理分配对地方政府财源建设所带来的风险。本文以陕西省延安市为例,认真分析财源结构、三次产业税收收入、税收收入与非税收收入的状况,以及省市分税的影响,深入研究现行财政分权影响地方财源建设的四大风险:税收与税源分离的风险、三次产业税源结构调整的风险、财政收支缺口的风险和税制改革滞后所引发的潜在风险,并深入剖析问题根源,积极探索优化资源型城市财源建设的制度路径。%The fiscal reform in 1994 contributed to tax revenue modernization, but fiscal decentralization is far from optimal. In recent years, there are problems with lagging local tax systems construction, local governments fiscal deficits, along with weak public services provisions. Fiscal reform is at the core of a new round of reforms, and their focus should be to reduce the risks of local tax systems from the non-optimal allocation of resource revenues. Using the Yan’an in the resource-rich Shaanxi Province as a case study, the paper analyzes the local government tax structure, the tax revenues of three of its key industries, the ratio between tax revenues and non-tax income, as well as the impact of tax separation. Next, we identify, the four major fiscal risks to the local government, which are the risk of tax separation, the risk of industrial structural adjustment, the risk from revenue and expenditure gaps, as well as the risk of lagging tax reforms. Finally, we advance a policy

    Based on morphological characters and molecular data, the pathogenic fungus of an unknown tobacco disease in Shaanxi Province in 2011 was identified. The suspected pathogen was isolated from diseased leaves of tobacco plants, and after pathogenicity tests and re-isolation of the pathogen, the strain LJL007 was determined to be responsible for the disease. The strain LJL007 was identified as Botrytis cinerea, whose teleomorph is Botryotinia fuckeliana on basis of morphological and cultural characters. We found that the sequences of the isolate LJL007 (Accession no.: HM17900) was 100% identical to that of B. fuckeliana (Accession no.: HM849615) by analyzing sequences of the ITS regions of ribosomal DNA, further confirming that the pathogen was Botrytis cinerea. Trametes versicolor polysaccharides cannot inhibit the mycelium growth and spore germination of Botrytis cinerea on potato dextrose agar. However, the polysaccharides had relatively good preventive effects on tobacco gray mould in the field, preventive effectiveness was 56.29%. The results of enzyme activity tests showed that Trametes versicolor polysaccharides significantly enhanced activities of chitinase and P-l,3-glucanase in the tobacco plants after treatment, the peak values of them increased by 56.89% and 429.83% as compared to the control treatment (treatment A: only spraying stilled water on the tobacco) respectively. These results indicated that Trametes versicolor polysaccharides could induce and improve resistance of tobacco plants to gray mould.%采用形态学观察和分子鉴定方法对2011年在陕西省发生的一种烟草未知病害的病原菌进行鉴定.从病叶组织分离纯化得到病原菌,通过致病性测定以及人工接种后再分离病菌,证明编号LJL007的菌株为该病的致病菌.依据病原菌的形态学和培养特征,将菌株LJL007鉴定为灰葡萄孢Botrytis cinerea Pers.,其有性型为富氏葡萄孢盘菌Botryotinia fuckeliana Whetzel

    Hunan province, Central South China, is a well-known nonferrous metal base in China. Mine exploiting and processing there, however, often lead to heavy metal pollution of farmland. To study the effects of mining activities on the soil environmental quality, four representative paddy fields, the HSG, SNJ, NT and THJ, in Y county, northern Hunan province, were investigated. It was found that the streams running through the HSG, SNJ and NT are severely contaminated due to the long-term discharge of untreated mineral wastewater from local indigenous mining factories. The stream at the HSG, for example, is brownish red in color, with high concentrations of Cu, Zn, Cd, Fe and Mn. The concentrations of Cu, Zn and Cd in all the stream water of the HSG, SNJ and NT exceed the maximum allowable levels of the Agricultural Irrigation Water Criteria of China. Correspondingly, the HSG, SNJ and NT are heavily polluted by Cu, Zn and Cd due to the long-term irrigation with the contaminated stream water. In comparison, both stream water and paddy fields of the THJ, far away from mining areas, are not contaminated by any heavy metals and hence regarded as a control in this study. The rice grain produced at the HSG, SNJ and NT has a high risk of Cd contamination. The rate of rice grain produced in the four paddy fields in Y county with Cd exceeding the safe level (Cd, 0.2 μg g-1) specified by the National Standards for Rice Quality and Safety of China reaches 90%. Cd content in the rice grain is positively significantly correlated with that in the paddy fields, especially with the content of diethylenetriaminepentaacetic acid (DTPA) - extracted Cd, suggesting that the heavy metal pollution of paddy fields has already posed a high risk to rice safety and human health. Soil enzyme activities and microbial biomass are significantly inhibited by the heavy metal pollution of the paddy fields. Microbial biomass C and N (MBC and MBN) at a severely contaminated site of the HSG are only 31

    2004-01-01

    Based on the analyses of 43 elements in 16 samples of the raw coal and feed coal collected from the northern Ordos basin and Shanxi Province, the modes of occurrence of these elements were studied using the method of cluster analysis and factor analysis, and the cleaning potential of the hazardous elements relatively enriched in the coals was discussed by analyzing six samples of the cleaned coal from the coal-washing plants and coal cleaning simulation experiments. The results shows that the elements Br and Ba show a strong affinity to the organic matter, Cs, Cd, Pb, Zn and Hg partly to the organic matter, and the other trace elements are mainly associated with the mineral matter. Cs, Mo, P, Pb,Zn and S have positive correlations with the two principal factors, reflecting the complexity of their modes of occurrence.Some elements that were thought to show a faint relationship (Be with S and Sb with carbonates) in other rocks are found to have a strong interrelation in the coals. Clay minerals (mainly kaolinite) dominate in the coals, and Ta, Th, Ti, Sc, REE,Hf, U, Se, W, V, Nb, Mo, Al, P, Cr, Pb and Zn are distributed mostly in kaolinite, while K, Rb, Cs, and Na have much to do with illite. Conventional cleaning can reduce the concentrations of most hazardous elements in various degrees. The hazardous elements S, As, Sb, Se, Mo, Pb, Cd and Hg relatively enriched in some coals from the area studied have a relatively high potential of environmental risks. However, by physical coal cleaning processes, more than 60% of As and Hg were removed, showing a high degree of removal, more than 30% of Sb, as well as S, Pb and Cd partly associated with the inorganic matter were removed. Se and Mo showing a relatively low degree of removal could be further removed by deep crushing of the coal during physical cleaning processes, and the concentrations of S, Pb, Cd and Hg with a partial association with the organic matter could be decreased in such ways as the coal blending

    Full Text Available This paper discusses the efforts of the royal family to moralise the environmental behaviour of their subjects in the name of the Sufficiency Economy philosophy solicited by King Bhumibol since the 1990s in Thailand. Drawing on ethnographic fieldwork conducted in Nan province, Northern Thailand, in 2008 and 2009, I focus particularly on Royal Projects recently promoted to correct the rural practices of the ethnic minority groups living in the hills of Nan. In the past, many of these ethnic groups took part in the Maoist insurgency while at present, they represent a key basin of support- ers for the reformist Red Shirts movement which is currently threatening the role of the monarchy in Thai politics. The research suggests that the recently increased trend of staging new projects for sustainable agro-forestry management in a ‘red’ area as Nan does not only aim at improving the conditions of mountain peoples and of the environment, but simultaneously increases the political influence of the conservative forces over this ‘ungovernable’ territory in times of political crisis. ----- Dieser Artikel diskutiert die Bemühungen der königlichen Familie in Thailand seit den 1990-er Jahren, das Umweltverhalten ihrer Subjekte im Namen der Sufficiency Economy Philosophie von König Bhumibol zu moralisieren.

In der Vergangenheit waren viele dieser ethnischen Gruppen am maoistischen Aufstand beteiligt, während sie heute ein zentrales Auffangbecken für UnterstützerInnen der reformistischen Rothemden, die derzeit die Rolle der Monarchie in der thailändischen Politik in Frage stellen, darstellen.

    Where the Neuquén Basin of Argentina abuts the Andes, hundreds of veins of solid hydrocarbon (bitumen) are visible at the surface. Many of these veins became mines, especially in the last century. By consensus, the bitumen has resulted from maturation of organic-rich shales, especially the Vaca Muerta Fm of Late Jurassic age, but also the Agrio Fm of Early Cretaceous age. To account for their maturation, recent authors have invoked regional subsidence, whereas early geologists invoked magmatic activity. During 12 field seasons (since 1998), we have tracked down the bitumen localities, mapped the veins and host rocks, sampled them, studied their compositions, and dated some of them. In the provinces of northern Neuquén and southernmost Mendoza, the bitumen veins are mostly sub-vertical dykes. They tend to be straight and continuous, crosscutting regional structures and strata of all ages, from Jurassic to Palaeocene. Most of the localities lie within 70 km of Tromen volcano, although four are along the Rio Colorado fault zone and another two are at the base of Auca Mahuida volcano. On both volcanic edifices, lavas are of late Pliocene to Pleistocene age. Although regionally many of the bitumen dykes tend to track the current direction of maximum horizontal tectonic stress (ENE), others do not. However, most of the dykes radiate outward from the volcanoes, especially Tromen. Thicknesses of dykes tend to be greatest close to Tromen and where the host rocks are the most resistant to fracturing. Many of the dykes occur in the exhumed hanging walls of deep thrusts, especially at the foot of Tromen. Here the bitumen is in places of high grade (impsonite), whereas further out it tends to be of medium grade (grahamite). A few bitumen dykes contain fragments of Vaca Muerta shale, so that we infer forceful expulsion of source rock. At Curacó Mine, some shale fragments contain bedding-parallel veins of fibrous calcite (beef) and these contain some bitumen, which is

    Paragonimus westermani is one of the most medically important lung flukes and is widely distributed in Asia. It exhibits considerable variation in morphological, genetic and biological features. In central provinces of Vietnam, a high prevalence of metacercariae of this species has been reported from the crab intermediate host, Vietopotamon aluoiense. In this study, we detected P. westermani metacercariae in two additional crab hosts, Donopotamon haii in Quang Tri Province, central Vietnam and Indochinamon tannanti in Yen Bai Province in the north. The latter is a new locality for P. westermani in a northern region of Vietnam where P. heterotremus is the only species currently known to cause human paragonimiasis. Paragonimus westermani metacercariae found in Vietnam showed considerable morphological variation but slight genetic variation based on DNA sequences from the nuclear ribosomal ITS2 region and the mitochondrial 16S gene. Co-infection of the same individual crabs with P. westermani and P. heterotremus and/or some other Paragonimus species was found frequently, suggesting potential for co-infection in humans. The findings of the present study emphasize the need for highly specific molecular and immunodiagnostic methods to differentially diagnose between P. westermani and P. heterotremus infections.

    While swine production is rapidly growing in South-East Asia, the structure of the swine industry and the dynamic of pig movements have not been well-studied. However, this knowledge is a prerequisite for understanding the dynamic of disease transmission in swine populations and designing cost-effective surveillance strategies for infectious diseases. In this study, we assessed the farming and trading practices in the Vietnamese swine familial farming sector, which accounts for most pigs in Vietnam, and for which disease surveillance is a major challenge. Farmers from two communes of a Red River Delta Province (northern Vietnam) were interviewed, along with traders involved in pig transactions. Major differences in the trade structure were observed between the two communes. One commune had mainly transversal trades, that is between farms of equivalent sizes, whereas the other had pyramidal trades, that is from larger to smaller farms. Companies and large familial farrow-to-finish farms were likely to act as major sources of disease spread through pig sales, demonstrating their importance for disease control. Familial fattening farms with high pig purchases were at greater risk of disease introduction and should be targeted for disease detection as part of a risk-based surveillance. In contrast, many other familial farms were isolated or weakly connected to the swine trade network limiting their relevance for surveillance activities. However, some of these farms used boar hiring for breeding, increasing the risk of disease spread. Most familial farms were slaughtering pigs at the farm or in small local slaughterhouses, making the surveillance at the slaughterhouse inefficient. In terms of spatial distribution of the trades, the results suggested that northern provinces were highly connected and showed some connection with central and southern provinces. These results are useful to develop risk-based surveillance protocols for disease detection in the swine familial

    Comprehensive methods, such as impression method, residual thickness method, deposition method etc., were used to divide Zhidan area into four basic units, I.e. Erosion highland, erosion valley, erosion slop and erosion monadnock. The research results indicate that pre-ancient landform had an important control action and influence on the formation, structure, sedimentation and reservoir characteristics of the hydrocarbon accumulation of the areas located at upper and lower erosion surface. The top erosion structural features of Chang 2 oil bearing set under the erosion surface well show some basic configuration of the eroded ancient landform of Indo-China movement; the early deposition of Yan'an formation above the erosion surface is a mirror image of the pre-ancient landforms; Yan 10 oil bearing set's top structure has a feature of centralized growth around an old upland background. Ancient erosion upland and erosion slope as well as the old upland background are major favorable sites of hydrocarbon accumulation located at upper and lower erosion surfaces, while the deep erosion valley has provided important channels to connect the lower oil source and upward hydrocarbon migration. The main reservoir types are strata-lithologic reservoir, structural-lithologic reservoir, relatively limited structure reservoir, lithology reservoir, etc.%综合运用印模法、残厚法及沉积法等将志丹地区前侏罗纪古地貌划分为侵蚀高地、侵蚀斜坡、侵蚀沟谷以及侵蚀残丘四个基本单元.研究结果表明:前侏罗纪古地貌对印支侵蚀不整合面上下之地层、构造、沉积、储层以及油气成藏特征等都具有重要的控制和影响.侵蚀面之下的长2油层组顶面剥蚀构造特征较好地反映了印支古地貌的基本格局;侵蚀面之上的延安组早期的沉积是前古地貌发育的镜像反映;而延10顶面构造则具有围绕古高地背景集中发育的特点.古高地与斜坡发育区是侵蚀面上下油气富集成藏的有利指向和主要场所,而深切的沟谷则为沟通下部油源以及油气运移提供了主要通道.油藏类型主要为地层-岩性油藏、构造-岩性油藏以及小而局限的构造、岩性油藏等.

    Objectives]Reasonable fertilization and effective mulching of soil have been the key measurement for high and stable agriculture production in the dry land of north Shaanxi Province. An optimized practice was proposed and its effectiveness in improving apple yield and quality was studied in the base of the farmer’s mode and the currently recommended measurement.[Methods]Field experiments were conducted in consecutive two years in three orchards each year. In farmers’mode, no organic fertilizer was used and the soil around the apple trees was cleared. The basal amount of N, P2O5, K2O was 300, 160, 120 kg/hm2, and the top dressing amount was 150, 80, 60 kg/hm2at germinating stage (March 20); The currently recommended management includes mulching the tree base soil with black film but cleared the soils between the tree rows, applying manure 22.5 t/hm2, the basal amount of N, P2O5, K2O was 200, 120, 180 kg/hm2, top dressing amount was 100, 60, 90 kg/hm2at fruit enlarging stage (August 10); the optimized measurement was: mulching tree base with black film and growing small rape in between the tree rows, organic manure amount was increased to 45 t/hm2, both the basal and top dressing amount of N, P2O5, K2O were 150, 90, 135 kg/hm2, but the dressing time was brought advanced at early stage of fruiting enlarging (July 10). The nutrient uptake in different growth periods of apple trees and the yield and quality of fruits were investigated, and the yield and quality of fruit were investigated.[Results]Compared with the extension pattern, the NPK contents of leaves in optimized model were averagely increased by 1.4%, 8.4% and 5.9% in young fruit period; by 5.6%, 15.5% and 8.1% in fruit enlargement period, and by 6.9%, 5.9% and 11.6% in ripening period. The fruit nutrient uptake was in order of optimized model >extension model > farmer model, and the difference between the optimized model and the farmer model was significant (P80 mm was in optimized model, and the

    Full Text Available The precise and accurate quantitative evaluation of the temporal and spatial pattern of carbon (C storage in forest ecosystems is critical for understanding the role of forests in the global terrestrial C cycle and is essential for formulating forest management policies to combat climate change. In this study, we examined the C dynamics of forest ecosystems in Shaanxi, northwest China, based on four forest inventories (1989-1993, 1994-1998, 1999-2003, and 2004-2008 and field-sampling measurements (2012. The results indicate that the total C storage of forest ecosystems in Shaanxi increased by approximately 29.3%, from 611.72 Tg in 1993 to 790.75 Tg in 2008, partially as a result of ecological restoration projects. The spatial pattern of C storage in forest ecosystems mainly exhibited a latitude-zonal distribution across the province, increasing from north (high latitude to south (low latitude generally, which signifies the effect of environmental conditions, chiefly water and heat related factors, on forest growth and C sequestration. In addition, different data sources and estimation methods had a significant effect on the results obtained, with the C stocks in 2008 being considerably overestimated (864.55 Tg and slightly underestimated (778.07 Tg when measured using the mean C density method and integrated method, respectively. Overall, our results demonstrated that the forest ecosystem in Shaanxi acted as a C sink over the last few decades. However, further studies should be carried out with a focus on adaption of plants to environmental factors along with forest management for vegetation restoration to maximize the C sequestration potential and to better cope with climate change.

    Peasant workers are the most vital human resource since China' s reform and opening up policy. They have made a historic contribution to China' s industrialization and urbanization. However, as the regulations of China' s economic structure, change in demand for labors, and the restriction of educational degree and labor skills or some other human capital factors, the vast majority of peasant workers is still in the edge and bottom of cities. They are primarily engaged in long-term, low-tech, low wages, and poor accommodation occupation, with full realization of their political status, economic rights, and social rights subject to many limitations. Causes for difficulties of peasant workers' integration into the mainstream of cities and the society and how the peasant workers share and enjoy achievements and civilization of reform and development with city dwellers are the important issues being paid much attention and to be addressed in China' s society. From the perspective of resource economics, the quality of human resources, i.e., human capital, becomes an important factor of peasant workers' integration into the urban life. This study laid the foundation of basic concepts and assumptions on building peasant workers' human capital and their urban living integration by investigating the case of peasant workers in Shaanxi Province from economic, social, and psychological/cultural dimensions. Results show that the elements of health, education, and labor skills in the human capital of peasant workers were significantly affected the dimension of their integration into cities. Work experience has a significant influence on the urban dimension of social integration, and shows a less effect on economic and psychological/cultural integration. This means that peasant workers in good health, on the one hand, are able to avoid spending much in city' s medical costs; on the other hand, they can obtain more job opportunities which help them more easily to

    The flow of rural labor to urban is a significant phe- nomenon in China during the last 20 years. In spite of many researches focus on the driving force of economy, terrain is an important index in the rural development. There is a question that whether the flow of rural labor has some relationships with terrain. The study used the relief degree of land surface (RDLS) as terrain index, and the cost distance model and the center of gravity model to analyze the relationship between terrain and labor flows. The results indicated: (1) In the last 20 years, the rural labor force was not simply flowing to the low terrain region in Shaanxi province. And the RDLS was constantly strengthening the influence on the movement. (2) The RDLS was low in Guanzhong region, and the translation of rural labors relatively was not significant. Since North Shaanxi act as the energy industry base, the number of rural labors there increased faster than in South Shaanxi. (3) The move- ments of economical centers took an important role in the change of rural labor centers, and terrain factors also showed a high cor- relation with them. It is found that the lower of the terrain index, the higher of the land intensive degree, the more intensive of non- agriculturalization process.

    A recent deployment of 55 broadband seismic stations around the northern Lake Malawi rift as part of the SEGMeNT project have provided a new dataset for imaging crustal and upper mantle structure beneath the Rungwe volcanic center and northern most segment of the Lake Malawi Rift. The goal of our study is to characterize the upper mantle velocity structure and determine to what extent the rifting has been influenced by magmatism. P relative arrival time residuals have been obtained for 115 teleseismic events with magnitudes > 5 in the 30 - 90 degree distance range. They are being tomographically inverted, together with travel time residuals from previous deployments for a 3-D velocity model of the upper mantle. Preliminary results indicate a low wave speed anomaly in the uppermost mantle beneath the Rungwe volcanics. Future results will determine if this anomaly exists under the northern Lake Malawi rift.

    Full Text Available Due to the complicated environment there are various types of highway disasters in Shaanxi Province (China. The damages caused are severe, losses are heavy, and have rapidly increased over the years, especially those caused by flood disasters along the rivers in mountainous areas. Therefore, research on risk evaluations, which play important roles in the prevention and mitigation of highway disasters are very important. An evaluation model was established based on the superposition theory of regional influencing factors to highway flood disasters. Based on the formation mechanism and influencing factors of highway flood disasters, the main influencing factors were selected. These factors include rainstorms, terrain slopes, soil types, vegetation coverage and regional river density, which are based on evaluation indexes from climate conditions and underlying surface of the basin. A regional risk evaluation of highway flood disasters in Shaanxi was established using GIS. The risk index was divided into five levels using statistical methods, in accordance with the regional characteristics of highway flood disasters. Considering the difference in upfront investments, road grade, etc, between expressways and trunk-highways in China, a regional risk evaluation of trunk-highway flood disasters was completed. The evaluation results indicate that the risk evaluation is consistent with the actual situation.

    An investigation into the prevalence and characteristics of child sexual abuse in the Northern Province (South Africa) was conducted. A total of 414 secondary school students in standard 9 and 10 in three representative secondary schools completed a retrospective self-rating questionnaire in a classroom setting. The questionnaire asked about childhood sexual abuse and the victim-perpetrator relationship. Results shows an overall (N = 414) child sexual abuse prevalence rate of 54.2%, 60% for males (N = 193), 53.2% for females (N = 216). Among them, 86.7% were kissed sexually, 60.9% were touched sexually, 28.9% were victims of oral/anal/vaginal intercourse. "Friend" was the highest indicated perpetrator in all patterns of sexual abuse. Many victims (86.7%) perceived themselves as not sexually abused as a child, and many (50.2%) rated their childhood as "very happy." A call is made for more research, publicity, and campaigns in the area of child sexual abuse in the Province.

    Middle Eocene through Upper Miocene sedimentary and volcanic rocks of the Flint Creek basin in western Montana accumulated during a period of significant paleoclimatic change and extension across the northern Rocky Mountain Basin and Range province. Gravity modelling, borehole data, and geologic mapping from the Flint Creek basin indicate that subsidence was focused along an extensionally reactivated Sevier thrust fault, which accommodated up to 800 m of basin fill while relaying stress between the dextral transtensional Lewis and Clark lineament to the north and the Anaconda core complex to the south. Northwesterly paleocurrent indicators, foliated metamorphic lithics, 64 Ma (40Ar/39Ar) muscovite grains, and 76 Ma (U-Pb) zircons in a ca. 27 Ma arkosic sandstone are consistent with Oligocene exhumation and erosion of the Anaconda core complex. The core complex and volcanic and magmatic rocks in its hangingwall created an important drainage divide during the Paleogene shedding detritus to the NNW and ESE. Following a major period of Early Miocene tectonism and erosion, regional drainage networks were reorganized such that paleoflow in the Flint Creek basin flowed east into an internally drained saline lake system. Renewed tectonism during Middle to Late Miocene time reestablished a west-directed drainage that is recorded by fluvial strata within a Late Miocene paleovalley. These tectonic reorganizations and associated drainage divide explain observed discrepancies in provenance studies across the province. Regional correlation of unconformities and lithofacies mapping in the Flint Creek basin suggest that localized tectonism and relative base level fluctuations controlled lithostratigraphic architecture.

    The Early Andean Magmatic Province (EAMP), consists of about 150 000 km 3 of volcanic and plutonic units in the Coastal Cordillera of northern Chile and southern Peru and represents a major magmatic Mesozoic event in the world, for which the precise age of the thick volcanic series was unknown. Thirty 40Ar/ 39Ar analyses were carried out on primary mineral phases of volcanic and plutonic rocks from northern Chile (18°30'-24°S). Reliable plateau and "mini plateau" ages were obtained on plagioclase, amphibole and biotite from volcanic and plutonic rocks, despite widespread strong alteration degree. In the Arica, Tocopilla and Antofagasta (700 km apart) regions, the ages obtained on lava flows constrain the volcanic activity between 164 and 150 Ma and no N-S migration of volcanism is observed. The uppermost lava flows of the volcanic sequence at the type locality of the La Negra Formation extruded at ca. 153-150 Ma, suggesting the end of the volcanic activity of the arc at that time. The oldest volcanic activity occurred probably at ca. 175-170 Ma in the Iquique area, although no plateau age could be obtained. The plutonic bodies of the same regions were dated between ca. 160 and 142 Ma, indicating that they were partly contemporaneous with the volcanic activity. At least one volcanic pulse around 160 Ma is evidenced over the entire investigated reach of the EAMP, according to the ages found in Arica, Tocopilla, Michilla and Mantos Blancos regions. The episodic emplacement of huge amounts of subduction related volcanism is observed throughout the whole Andean history and particularly during the Jurassic (southern Peru, northern Chile and southern Argentina). These events probably correspond to periodic extensi
