| 摘 要： | 本文以长江三峡干流河岸植物群落为研究对象,对群落的物种组成、物种多样性进行了分析,并利用TWINSPAN和DCA对植物群落进行等级式划分。结果表明:河岸植物区系组成较为复杂,以温带成分为主,有着较高比率的世界分布成分。灌、草丛群落之间的物种多样性差异不显著,但部分草丛的不同层次间存在较大差异。TWINSPAN 和DCA分析显示,河岸植物群落呈现沿湿度梯度方向的分布格局。图2表3参8。

| Abstract: | Sixteen different vegetation types of grassland and shrubland were selected to study the component and diversity of plant species of riparian plant communities along main channel in the Three-Gorges areas. Species richness (s), Simpson index (D), and Shannon-Weiner index (H) were used to study the biodiversity and the hierarchical classification was carried out by the methods of TWINSPAN and DCA ordination. The results showed that the components of flora were complex and dominated by the temperate type in the riparian plant communities. Species diversity was not different between the communities, but Shannon-Weiner indexes of different layers in some grassland were significantly different. TWINSPAN and DCA indicated that riparian plant communities distributed along the gradient of moisture. |
