摘要: 选择清香木(Pistacia weinmannifolia)典型群落样地,划分为不同干扰类型。采用物种丰富度、Simpson指数(D)、Shannon-Wiener指教(H)和均匀度指数(E)等物种多样性指数及改进的M-Godron稳定性测定方法,对清香木天然种群的物种多样性和稳定性进行分析。结果表明:清香木群落乔木层和草本层物种多样性表现为干扰弱>干扰强,而灌木层为干扰弱<干扰强;在不同干扰强度下群落稳定性均靠近稳定状态,其相对的稳定性比较是干扰强>干扰弱,表现出与群落物种多样性不同的趋势。

关键词: 清香木群落, 物种多样性, 稳定性, 干扰

Abstract: Sample plots of typical community of Pistacia weinmannifolia were set up and divided into different types of disturbance.By using the species richness,the simpson index (D),the shannon-wiener index (H),and the Pielou index (R)as well as a community stability index and the improved M-Godron method.Species diversity and stability of Pistacia weinmannifolia community under two different intensities of disturbance were analysis.The results showed that the species diversity index of the tree layers and the herbaceous layer in the strong interference was higher than that of weak interference,but to the shrub layer,the fact was reversed.The analysis shows that community stability under different disturbance intensities is stable or near steady state,the relative stability of relatively strong interference> interference weak,showing species diversity and different trends.

Key words: Pistacia weinmannifolia community, species diversity, stability, disturbance
