【摘要】 Shaanon-Wiener多样性指数和均匀度以其简单易用而被广泛应用于生物多样性和群落生态学等研究中。然而,由于缺乏适合的统计检验等原因,其分析的可信性较低。本研究以Shaanon-Wiener指数和Ewens- Caswell检验为基础,研制了生物多样性和均匀度显著性统计检验的Internet计算软件EwensCaswellTest。该软件由4个Java类和一个HTML文件组成,可运行于多种网络浏览器上。用EwensCaswellTest对水稻田节肢动物群落多样性(15个地点,17个功能群),以及中国民族HLA-DQB1等位基因的多态性(12个民族和人群,17个等位基因)进行了分析。结果显示,该检验可有效地反映多样性和均匀度的显著性。更多还原

【Abstract】 Shaanon-Wiener measures on biodiversity and evenness were widely used in community ecology and bio diversity researches.Their reliability,however,were largely restricted because of the shortage of statistic test on the measures.In this study,the Web-based computational software for the test based on Ewens-Caswell model and Shaanon-Wiener measure,EwensCaswellTest,which is comprised of4Java classes and a HTML file,was developed.It can be run on various Web browsers.Rice invertebrate diversity(15sampling sites,17functional groups)and human HLA-DQB1allele gene polymorphism(12human races or populations,17allele genes)were analysed using software Ewens CaswellTest.The results showed that the statistic significance of diversity and evenness can be effectively detected by the test.更多还原
