滇中磨盘山不同演替阶段林分结构及物种多样性研究
Stand Structure and Species Diversity at Different Succession Stages in the Mopan Mountain in Central Yunnan
摘要
Abstract
In order to explore the structural characteristics of the stands at different succession stages in central and subtropical Asia and their relationship with species diversity,three typical forest stands in the early,middle and late stages of succession in the Mopan Mountain in central Yunnan were selected as re-search objects,the changes of multiple indicators of stand spatial structure and species diversity index in different succession stages were quantitatively studied,and the interaction relationship between the two was explored with the help of redundancy analysis.The multivariate distribution was used to comprehen-sively describe and evaluate the spatial structure parameters of the stands.The results showed that the spa-tial structure parameters of the stands differed significantly among the stands at different succession sta-ges,and community succession had the strongest influence on the degree of tree species mixing and forest layer difference,both reaching the maximum values in the late succession stage,which were 0.703 and 0.511,respectively.The species richness of the tree layer,Simpson index,Shannon-Weiner index and Pielou uniformity index all increased with succession,and the indices were the highest in evergreen broadleaved forests.The degree of tree species isolation was the main driver of species diversity in the tree layer,fol-lowed by diameter at breast height,structure and stand density.The results can provide a theoretical basis for stand adjustment and sustainable forest management in this area.关键词
