生态多样性模型的理论分析及应用:以新疆维吾尔自治区阜康地区为例 Theoretical analysis of ecological diversity models and their application in Fukang of Xinjiang Uygur Autonomous Region

YUE Tianxiang(岳天祥); MA Shengnan(马胜男); WU Shixin(吴世新); ZHAN Jinyan(战金艳)

生态多样性是诸如物种、景观元和HLZ生态系统等研究对象丰富性和空间分布均一性的综合.理论分析表明,Shannon模型存在诸多理论的缺陷和应用的局限性.例如,Shannon模型具有大样本需求,不能反映空间尺度信息,也不能表达丰富性方面的多样性信息.本文引进Scaling生态多样性模型,以新疆维吾尔族自治区阜康市为案例区进行模拟研究.结果表明,随着空间分辨率逐渐粗化,Shannon模型模拟结果缺乏规律性,而Scaling生态多样性模型模拟得到的景观元多样性在30m×30m~150m×150m的空间尺度范围内不受空间分辨率的影响;在150m×150m~480m×480m的空间尺度范围内,随着空间分辨...

UVA-induced cyclobutane pyrimidine dimers form predominantly at thymine–thymine dipyrimidines and correlate with the mutation spectrum in rodent cells

Perdiz, Daniel; Rochette, Patrick J.; Drouin, Régen; Therrien, Jean-Philippe; Bastien, Nathalie; Drobetsky, Elliot A.

Ligation-mediated PCR was employed to quantify cyclobutane pyrimidine dimer (CPD) formation at nucleotide resolution along exon 2 of the adenine phosphoribosyltransferase (aprt) locus in Chinese hamster ovary (CHO) cells following irradiation with either UVA (340–400 nm), UVB (295–320 nm), UVC (254 ...

Syntactic ambiguity resolution and the prosodic foot: cross-language differences

Perry, C; Kan, MK; Matthews, SJ; Wong, RKS

In this study we examined syntactic ambiguity resolution in two different Chinese languages, Cantonese and Mandarin, which are relatively similar grammatically but very different phonologically. We did this using four-character sentences that could be read using two, two-syllable sequences (2-2) or ...

Seasonal trace-element and stable-isotope variations in a Chinese speleothem: the potential for high-resolution paleomonsoon reconstruction

Johnson, Kathleen R.; Hu, Chaoyong; Belshaw, Nick S.; Henderson, Gideon M.

We report the presence of clear annual cycles in trace-element (Mg/Ca, Sr/Ca, Ba/Ca, and U/Ca) and stable-isotope (δ¹⁸O and δ¹³C) composition in an annually banded stalagmite from Heshang Cave, Hubei Province, China (30.44°N, 110.42°E). Through a combination of micromilling and in situ analysis (LA-...

Reconstruction of temperature series in China for the last 5000 years

Ge, Quansheng; Wang, Shunbing; Zheng, Jingyun

A temperature series with a 100 year resolution for the last 5000 years in China has been reconstructed by using 31 longterm temperature proxy series selected from recent publications in the last 20 years. The proxy records include pollens, stalagmites, lakesediments, peat, ice cores and historical ...
