Abstract

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
