城市公园是城市园林绿地系统的主体,也是城市植物多样性最集中的地方,研究城市公园树种多样性可为城市生物多样性保护提供基础数据.对沈阳市城市公园植物群落树种组成、物种丰富度、物种多样性进行调查统计和比较分析.结果表明:204块样地中共计植物有38科76属139种,乔木89种,灌木50种.沈阳城市公园的乔木层丰富度为5.115 7,Simpson优势度指数为0.640 3,Shannon-Wienner多样性指数为1.295 5,Pielou均匀度指数为0.788 9;灌木层丰富度为3.278 9,Simpson优势度指数为0.543 0,Shannon-Wienner多样性指数为0.941 7,Pielou均匀度指数为0.703 9.

Urban parks are the main body of urban greenbelt system ,which also are the place that biodiversity highest centralized in city. It can provide the basic data for urban biodiversity conservation by the research on the tree diversity of greenbelt in urban.The trees of different park in Shenyang city were studied.The composition of plant community, and the species diversity index were analyzed and compared.The results showed that there were 38 families,76genera and 139 species, including 89 kinds of trees,50 kinds of shrubs.The species abundance indices of tree layer in Shenyang city parks were5.115 7, 0.640 3 of the Simpson index, 1.295 5 of the Shannon-Wienner index and 0.788 9 of the Pielou index.The species abundance indices of shrub layer were3.278 9, 0.543 0 of the Simpson index, 0.941 7 of the Shannon-Wienner index and 0.703 9of the Pielou index.
