十五个物种多样性指数的比较研究

用关帝山植被数据对１５个物种多样性指数进行了比较研究，结果表明：各指数间有着密切的关系，它们都能较好地反映多样性特征，但其中较好的丰富度指数依次为：Ｐａｔｒｉｃｋ指数、Ｍｅｎｈｉｎｉｃｋ指数、Ｍａｒｇａｌｅｆ指数。较好的均匀度指数依次为：修正的Ｈｉｌ指数、Ａｌａｔａｌｏ指数、Ｐｉｅｌｏｕ指数（ｅ）、Ｐｉｅｌｏｕ指数（Ｊｓｗ）、Ｐｉｅｌｏｕ指数（Ｊｓｉ）、ＭｃＩｎｔｏｓｈ指数。较好的多样性指数依次为：Ｓｈａｎｎｏｎ－Ｗｉｅｎｅｒ指数、Ｓｉｍｐｓｏｎ指数、Ａｕｄａｉｒ和Ｇｏｆ指数、种间相遇机率、ＭｃＩｎｔｏｓｈ指数、Ｈｕｒｌｂｅｒｔ指数。相关系数分析也很好地说明了这个问题。

A COMPARISON OF FIFTEEN SPECIES DIVERSITY INDICES

Using Guandi Mountain vegetation data, 15 species diversity indices were compared. The results illustrate: they are related with each other and each index can reflect diversity effectively, but better richness index is:Patrick index, Menhinick index, Margalef index; the preferable order of the evenness index is:Modified Hill index, Alatalo index, Pielou index(e), Pielou index(Jsw), Pielou index(Jsi), McIntosh index; the diversity index is: Shannon-Wiener index, Simpson index, Audair & Goff index, Species meet probability, McIntosh index, Hurlbert index. Correlation coefficients illustrate this point as well.
