摘要
用组平均聚类法将汾河河漫滩草地植被分为 12个群落 ,并对每个群落的群落学特征进行了分析。在此基础上采用物种丰富度指数、Shaanon -Weinor指数和Alatalo均匀度指数比较群落和群落样地相关性结果表明 :群落和群落样地物种多样性有明显差异 。
The grassland vegetation in flood plain of the Fen River were classified into 12 communities by the group average clustering method. The community characteristics of every community were described. The diversity of 12 communities and 11 plots were analyzed by the species richness indices, Shaanon-Weinor indices and Alatalo's evenness indices. The results showed that there are evident differences among communities and plots. These differences are closely related to the habitant.
