Investigations were conducted by sample plot survey on plant species, their families and genera, composition of arbor, shrub and herb, ratio of evergreen and deciduous species as well as on community structure of community in 5 parks, 5 resident areas and 5 forest parks in Wenzhou, Zhejiang province. The result indicated that number of plant species and their families and genera was ordered by forest park>resident area>park. Evergreen species at arbor layer in parks and resident areas were less than that in forest park, while that at shrub layer were the opposites. Communities in each sample plot had few exotic plant species and characters of zonal flora. Height, canopy density of arbor layer, and height and coverage of shrub layer in parks and resident areas was far lower than that in forest park, while the coverage of herb layer was the opposite.%以温州市5个公园植物群落、5个居住区植物群落和5个森林公园植物群落为主要研究对象，研究了城市绿地群落与森林公园植物群落的物种数量、科属组成、乔灌草组成、常绿落叶比、群落结构，结果表明：总的物种数和所属科属数上，都是森林公园植物群落>居住区群落>公园群落；城市绿地群落中乔木层常绿树种的比例低于森林公园植物群落，而灌木层常绿树种比例又高于森林公园植物群落，大体上群落树种基本以常绿种为主；城市绿地群落中，公园群落常绿种比例高于居住区；城市绿地群落与森林公园植物群落的外来种比例不高，在区系组成上有较强的地带性特征，乡土种应用较为广泛；城市绿地群落乔木层的高度、郁闭度和灌木层的高度、盖度均远低于森林公园植物群落，而草本层的盖度又高于森林公园植物群落。
