摘　　要：对南京10个主要城市水体滨水区植被群落的物种组成、生物多样性指数(Simpson指数、Shannon-Wiener指数)、群落相似性系数(Jaccard相似性系数)等进行分析研究。结果表明,南京城市滨水植物群落中乔灌木种类丰富,水生植物则比较单一;滨水区的全部植物种中,乡土植物的比重较小,且个别样地出现入侵物种;早期开发的滨水绿地在各植被层上的物种多样性都要优于新开发绿地;不同利用类型的滨水区绿化形式趋同,物种多样性较低。本研究对城市滨水植物的应用与保护提出了一定的意见与建议。In this article the composition,diversity index（Simpson index and Shannon-Wiener index）,as well as similarity index（Jaccard index） of 10 major urban waterfront plant communities in Nanjing are analyzed.The results can be summed up as following：the species of tree layer and shrub layer are plentiful,but the aquatic plant layer is relatively simple;the proportion of native plants is low,and invasive species appear in some samples;the species diversity of each plant layer of the early developed waterfronts is higher than that of the new ones;the green forms of different types of waterfronts are similar,and their species diversity is low.Suggestions are given in order to utilize and protect the urban waterfront plants more reasonably.
