以杭州市区为对象，研究了杭州城市绿地的主要群落类型和植物多样性特征。结果表明：研究区域共记录维管束植物221种，隶属于110科、179属，可分为16种群落类型，主要以常绿阔叶林为主。现有城市绿地中树木生长状况良好，但植物群落结构的完善程度不高。植物生长型与群落多样性指数、丰富度指数的关系由大到小的顺序为：乔木层、灌木层、草本层。均匀度指数乔木层略偏高，灌木层和草本层的均匀度指数相近，群落间变异幅度较小。各群落丰富度指数、Shannon-Wiener指数和Simpson指数总体趋势基本一致，均匀度指数与Alatalo指数也反映出基本一致的趋势。

The study was conducted to investigate the main community type and species diversity characteristics of urban green space in Hangzhou.221species of vascular plants in 110 families and 179 genera were recorded at the study area.The study area was divided into 16 community types and dominated by evergreen broad-leaf forest.The existing trees in urban green space are in good condition, but all structural complexity of plant communities is still at low level.The species rich-ness and diversity index for different strata is in the order of tree stratum>shrub stratum>herb stratum.For the evenness, tree stratum is slightly higher, shrub stratum is similar to herb stratum, and both are with small variation among communi-ties.The richness index, Shannon-Wiener indexand Simpson index of each community have the consistent trend, and the pielou index and Alatalo index also show the same trend.
