摘要： 按绿地类型和干扰类型，分别调查了玉溪城市园林植物群落，对比分析了各类型绿地植物群落树木的优势度指数、Simpson指数、Shannon指数等指标。结果表明：（1）自然森林乔木层的优势度较大，乔木层优势种的集中程度高。（2）自然型绿地群落乔木种类的多样性低于人工型绿地植物群落。（3）城市中不同类型绿地植物群落总体的物种多样性依次为公园绿地>校园绿地>广场绿地。

Abstract: The weighted average tree species abundance, Simpson index, Shannon index and dominance index were analyzed for natural forest communities, half-natural forest communities and some types of gardening plant communities dominated by trees. The results indicated that the dominance index of the arbor layer is great in the natural forest, the number of dominant of the arbor layer is lower than that in the artificial forest, and the species diversity of the communities in park green spaces is the richest of the three types in the city.
