摘　　要：城市公园是城市绿地的重要组成部分,调查分析城市公园树种多样性可以为城市多样性的保护提供依据,完善城市公园结构,改善城市生态环境。对通辽市的5个公园进行抽样调查,分析和比较其物种组成和多样性。结果表明:通辽市公园共有物种70种,隶属于25科48属,通辽市公园乔木层的丰富度指数为49,Simpson优势度指数为0.9257,Shannon-wiener多样性指数为3.0114,Pielou均匀度指数为0.7738;灌木层的丰富度指数为21,Simpson优势度指数为0.9041,Shannon-wiener多样性指数为2.6269,Pielou均匀度指数为0.8161。根据对物种多样性及乔灌木层的物种多样性的分析,对各公园的群落组成、结构特点提出改造建议。City parks are an important part of urban green space. The investigation and analysis of the urban park species can provide the basis for the protection of the urban diversity, perfect the urban park structure and improve the urban ecological environment. The species composition and diversity were analyzed and compared through the sample survey of five different park in Tongliao City. The results show that there are 70 species, belonging to 25 families 48 genera. The richness index is 49. Simpson dominance index is 0.9257. Shannon-wiener diversity index is 3.0114. Pielou evenness index is 0.7738 in arbor layer. The richness index is 21. Simpson dominance index is 0.9041. Shannon-wiener diversity index is 2.6269. Pielou evenness index is 0.8161 in shrub layer. Based on those, the reasonable suggestion of the species composition, structure characteristics and improvement is proposed.
