通过１９８６ 和１９９６ 年对缙云山森林次生演替系列群落的重复调查，运用构成指数对这些群落进行演替排序，研究缙云山森林次生演替过程中的物种多样性动态．结果表明，构成指数（ ＣＩ） 可适当改变空间代替时间的局限；在缙云山森林次生演替过程中，物种丰富度呈先变大后变小的趋势，物种均匀度没有明显的动态规律，这与种间（ 内） 关系密切相关，因而适当干扰有利于群落内物种多样性的增大
Through repeated surveys of the forest secondary succession series in Jinyun Mountain in 1986 and 1996, the composition index was used to rank the succession of these communities to study the dynamics of species diversity in the secondary succession process of the forest in Jinyun Mountain. The results showed that composition index (CI) could appropriately change the time of spatial substitution. During the succession of forest secondary succession in Jinyun Mountain, species richness increased first and then decreased, and there was no obvious dynamic law of species evenness Is closely related to the interspecific (inter) relationship, so proper disturbance is conducive to the increase of species diversity in the community
