摘　　要：区域尺度物种多样性评价不仅是生物多样性研究的一个重要内容,对于保护区的建设也具有指导意义.选取全国具有代表性的57处自然保护区,构建大尺度陆栖脊椎动物物种多样性数据库,在物种水平上,探讨了一个用于区域物种多样性综合评价的E指数,即给予每个类群相同的权重,由陆栖脊椎动物四大类群综合计算而得.通过对物种丰富度的变形P指数和E指数进行比较,得到以下结论:E指数与物种丰富度有着极显著的相关性,二者都能用来评价物种多样性,但E指数比物种丰富度更能无偏颇地评价区域物种多样性,包含的信息更多,而P指数则会低估两栖类和爬行类物种数量较多的自然保护区的物种多样性,这种低估对于南方的保护区尤为严重.因此,为使区域尺度物种多样性评价更加科学合理,本文推荐运用E指数.In the recent years,assessment of species diversity at regional scale not only is a crucial part of biodiversity research,but also has important implications for biodiversity conservation in nature reserves.This paper built firstly species diversity databases of terrestrial vertebrates for 57 typical nature reserves across China and then,evaluated an index E used in comprehensive assessment of species diversity at regional scale,which treated all the vertebrate taxa the same.From the account of 4 main taxa of terrestrial vertebrates,it compared index P,the modified form of species richness,with index E.The results showed that,index E had significantly positive relationship with index P（i.e.species richness）.Both index E and index P can be used to assess the regional species diversity,however,index E can accurately assess the data and provide more information than index P,which incompletely assessed the diversity of natural reservation areas with more reptiles and amphibians in southern natural reserves.Therefore,it has been recommend that the use of index E in the assessment of species diversity in nature reserves other than species richness.
