摘　　要：对上海人工常绿阔叶林群落特征进行了调查，分析了这些林分群落的植物组成、结构、性质，并计算了各主要种群的相对密度、相对频度、相对显著度及重要值。结果表明，该群落种类组成有40科73属76种，以草本植物占数量优势。乔木层中香樟和杜英为优势树种；生活型组成则以一年生植物和高位芽植物占显著优势（占36．84％和32．89％）。群落各层的植物多样性指数次序为草本层〉灌木层〉乔木层。Community characteristics including compositions and structures of water conservation torests of artificial evergreen broad-leaved forest in Shanghai were determined based on the field investigations of typical sample plots. Relative density, frequency, dominance and important values were calculated as well. The results demonstrated that the community consisted of 76 species, 73 genera and 40 families, and herbs were the dominant species in the community. Cinnamomum camphora and Elaeocarpus sylvestris were the predominant species in the tree layer. Therophytes and Phanerophytes were the significant dominant life form with the value of 36.84% and 32.89%, respectively. Plant diversity indices were. herb layer 〉shrub layer 〉 tree layer.
