| 摘 要： | 基于43个代表性样地调查资料,用系统聚类方法中的离差平方和法将元江干热河谷的主要植被分为7个群落类型, 并采用Gleason物种丰富度指数、Simpson多样性指数和 Shannon Weiner多样性指数以及Pielou均匀度指数比较了各群落的物种多样性特征。结果表明:不同群落之间的物种多样性存在着明显的差异,这些差异与群落的分布地点、小生境有密切关系。

| Abstract: | The vegetation in the dry-hot valley of Yuanjiang was classified into 7 communities by the Ward’s clustering method based on the data of 43 sampling plots. Characteristics and habitats of these communities were also discussed. Diversities of these communities were analyzed by the Gleason richness index,Shannon-Weiner diversity index,Simpson’s diversity index and Pielou evenness index. It was revealed that the species diversity varied conspicuously in these communities and were affected by habitats. |
