在针阔混交林向阔叶林演替过程中，物种丰富度指数表现为较大的波动性。
In the process of secondary succession from conifer - broadleaf forest to broadleaf forest, species richness fluctuated remarkably.
物种丰富度指数与均匀度指数并非存在正相关关系，均匀度指数反映的是物种分布的均匀程度，并不反映其物种数量的多少。
The plant species richness index is not positive relevant to species evenness index for which represents the evenness extent of species distribution instead of the quantity of species.
