通过上海城区三条主要交通干道绿带的乔木层和灌木层物种丰富度指数、Ｓｉｍｐｓｏｎ指数、Ｓｈａｎｎｏｎ－Ｗｅｉｎｅｒ指数和Ｐｉｅｌｏｕ均 匀度指数的分析，结合群落物种组成、群落类型以及１公里绿带木本植物丰富度的比较，对绿带木本植物多样性进行了比较分析，并进 一步讨论了交通绿地物种多样性存在的问题和改善途径。
The species abundance, Simpson index, Shannon--Weiner index and Pielou's evenness index for tree layers and shrub layers of the three urban principal arierial roads green- belt in Shanghai were investigated, and the types and species composition of the communities and the woody plants ahundance of 1km greenbelt of the roads were also compared.
