在近代生态学中,多样性指数常被用来测定群落中物种的丰富度及其均匀性,同时也用来衡量植物,野生动物,群落结构等数量特征,均匀程度的一个灵敏度较高的定量指标。多样性指数的计算方法有若干个,其值均近似,笔者在此以信息论为基础的 Shannon—wiener 指数的一般公式进行计算,谈在实践
In modern ecology, the diversity index is often used to determine the abundance and homogeneity of species in the community. It is also used to measure the quantitative characteristics of plants, wildlife, community structure, etc., and a more sensitive quantitative index. There are several methods for calculating the diversity index, and their values are similar. The author calculates the general formula of the Shannon-wiener index based on information theory,
