为探讨随着湘江水位的周期性变化是否导致河岸带植物群落多样性的变化,在长沙城区段的湘江东岸设置了30个样方进行调查。计算群落各层次的重要值以及Patrick丰富度指数、Shannor-Wiener多样性指数、Simpson优势度指数和Pielou均匀度指数等对群落多样性进行分析。结果表明:(1)湘江长沙城区段河岸带植物群落物种较丰富,样方中共出现62种植物,隶属于59属30科;(2)群落中乔灌藤草各层次的重要值分别为26%、27%、2%、68%,丰富度指数分别为11、7、4、40,多样性指数分别为0.77、0.68、0.11、2.00,优势度指数分别为0.01、0.01、0、0.02,均匀度指数分别为0.19、0.16、0.03、0.49。群落各层次的4种多样性指...

In order to explore whether or not with the periodical change of the Xiangjiang river had resulted in the change of plant community diversity of riparian zone, we set up 30 samples randomly for the field investigation, between the Houzishi bridge with the Xiangfu bridge along the eastern coast of the Xiangjiang river. We analyzed the diversity of the communities by calculating the important values, the Patrick index, the Shannor-Wiener index, the Simpson index, and the Pielou index of all layers of the communities. The results showed that: The ...
