摘要: 用稀疏曲线法、Shannon -Weaver指数(H')、Pielou指数(J')分析了重庆缙云山四川大头茶三类群落物种丰富度、多样性和均匀度。结果表明,三类指数均表现为:常绿阔叶林(Ⅰ) > 针阔混交林(Ⅱ) > 纯林(Ⅲ)。群落各层中,草本层多样性高,乔木层较低;丰富度主要与草本层相关,而H'和J'与乔木层和灌木层相关较大。生境优越,多样性高;群落透光率也影响林下植物物种多样性。三类群落以Ⅱ→Ⅲ→Ⅰ进程演替,多样性表现为高→低→高。

Abstract: Used with the method of rarefraction curve and diversity indexes (Shannon-Weaver's (H') and Plelou's (J')), species richness, diversity and species evenness were analyzed in three Cordonia acuminata communities of Jinyun mountain in Chongqing.The results show that the values of species richness, H' and J' in three G.acuminata communities are in following order:evergreen broad-leaved community (Ⅰ) > mixed coniferous and broad-leaved community (Ⅱ) > pure community (Ⅲ).The diversity of herb stratum in three communities is highest and that of tree stratum is lowest.Species richness in the community is higher related with herb strtum.H' and J' are higher related with tree and shrub stratum.The light transparence of community and other environment conditions can affect diversity.During succession of communities from Ⅱ to Ⅲ, and to Ⅰ, the diversity shows:high→low→high.
