生物群落多样性的测度方法VI：与多样性测度中有关的统计问题

物种多样性测度是(群落的)总体参数，它们常常是未知的，需要通过抽样将它们估计出来，因此，必须了解估计量的抽样性质。本文对与一些多样性测度的均值、方差的估计和假设检验以及大、小样本分布等有关的问题作了综述。可以看出大多数多样性测度的抽样性质还不清楚，有些甚至根本就没有研究过。Pielou的合并样方法和刀切法是两个比较通用的方法，用它们可以解决其中的一些问题。但相比之下，刀切法更实用。

Measurement of biotic community diversity VI: the statistical aspects of diversity measures

Species diversity is a community parameter. It’s usually unknown , and must be estimated with asample or samples from the community. Therefore the sampling properties of the estimators must be examinedin order to accurately estimate species diversity of a community. The estimation of means and variances , hypothesis testing , and large or small sample distributions for some diversity measures are reviewed in this paper.However , the sampling properties of many diversity measures remain unclear , and some of them have not beenstudied at all. It is concluded that Pielou′s pooled quadrat method and jackknife method are two better methods to solve some of the problems , and jackknife method is more practical in application than the other.
