| 摘 要： | 采用样地样方调查法,通过Margalef指数、Shannon-weiner指数和Pielou指数综合分析了北京市3条主要河流(潮白河、拒马河、清水河)的滨岸带植被物种丰富度、多样性及均匀度。结果表明:在11个样地中共记录植物74科248种,其中蕨类植物3科7种,双子叶植物56科166种,单子叶植物15科75种。清水河滨岸带的植物Mar-galef指数、Shannon-weiner指数和Pielou指数均高于潮白河与拒马河,植被状况保持较好。

| Abstract: | Based upon the Margalef index,the Shannon-Wiener index and the Pielou index,the species richness,the diversity and the evenness of riverfront vegetations of three main rivers（the Chaobai River,the Juma River and the Qingshui River） in Beijing were comprehensively analyzed by quadrat survey procedure.The results showed that there were 248 species of 74 families in 11 type places,including 7 species of 3 Pteridophyta families,166 species of 56 Dicotyledons families and 75 species of 15 Monocotyledons families.The Margalef index,the Shannon-Wiener index and the Pielou index of riverfront vegetations of the Qingshui River are higher than those of the Chaobai River and the Juma River,with a better vegetation maintained. |
