预计一些广泛使用的多样性指数之间存在正相关关系。这些相关性来自指数的定义，因此很难解释计算出的它们之间的相关系数。这些预期相关性的值取决于为描述不同社区样本中若干指数值的分布而假定的概率分布。唯一的迹象，在公布的数据中，可能会影响这些指数值的生物现象是减少物种丰富度增加的物种均匀度的方差。
Positive correlations are expected between a number of widely used diversity indices. The correlations arise from definitions of the indices, and make it difficult to interpret calculated correlation coefficients between them. The value of these expected correlations depends on the probability distributions assumed to describe the distributions of values of the several indices over samples from different communities. The only indication, in published data, of a biological phenomenon that may possibly influence values these indices take is a decrease in variance of species evenness as species richness increases.
