两种干扰强度下岩生红豆天然群落特征及物种多样性分析

【目的】研究两种干扰强度下岩生红豆天然群落结构与物种多样性特征，为其群落保护、物种多样性保育和可持续利用提供理论依据。【方法】采用常规群落学调查方法，设置6个典型群落样地，统计物种丰富度指数、Shannon—Wiener和Simpson生物多样性指数及Pielou均匀度指数值，分析两种干扰强度下群落结构与物种多样性特征。【结果】研究区岩生红豆各个群落皆以高位芽植物为主，以热带成分略占优势；黔灵山3个样地群落有维管植物29种，隶属25科26属，笔架山3个样地群落有维管植物74种，隶属40科59属，两地群落各层物种丰富度和多样性程度亦有较大差异。【结论】强干扰型对黔灵山岩生红豆群落结构和物种多样性...

Summary:【目的】研究两种干扰强度下岩生红豆天然群落结构与物种多样性特征，为其群落保护、物种多样性保育和可持续利用提供理论依据。【方法】采用常规群落学调查方法，设置6个典型群落样地，统计物种丰富度指数、Shannon—Wiener和Simpson生物多样性指数及Pielou均匀度指数值，分析两种干扰强度下群落结构与物种多样性特征。【结果】研究区岩生红豆各个群落皆以高位芽植物为主，以热带成分略占优势；黔灵山3个样地群落有维管植物29种，隶属25科26属，笔架山3个样地群落有维管植物74种，隶属40科59属，两地群落各层物种丰富度和多样性程度亦有较大差异。【结论】强干扰型对黔灵山岩生红豆群落结构和物种多样性影响较大，致使其更新层不发达，不利于岩生红豆的繁育更新；而弱干扰型对笔架山岩生红豆群落的影响较小，其更新层发达，有利于群落岩生红豆的更新演替。

[Objective]Natural community structure and species diversity characteristics in Ormosia saxatilis fiehl un- der two different intensities of disturbance were studied to provide theoretical references for community protection, conser- vation and sustainable utility of species diversity. [Method]By using conventional coenology investigation method with six typical community plots, the characteristics of species diversity of Ormosia saxatilis communities under two differcnt inten- sities of disturbance were analyzed based on species richness index, the Shannon-Wiener and Simpson biodiversity index, and the pielou evenness index.
