摘　　要：根据所处的空间位置以及建成时间的不同,对南京20个居住区的40个人工植物群落样地进行了群落学调查,分析了样地内植物的组成、群落的层次结构特征以及生物多样性。结果表明:植物群落的物种组成具有一定的"时代性";垂直绿化使用较少,物种相对单一,乡土树种应用较少;生物多样性指数相对偏低。根据对南京地区次生林群落结构的调查结果,提出优化居住区人工植物群落的对策。According to the different space locations and establishment time, the 40 plantation community samples from 20 residential areas in Naming were surveyed to analyze its plant composition, layer structure characteristics and biodiversity. The results showed that the species composition of plantations was characterized with the different times. The vertical plants and the regional plants were relatively employed less and the species were comparatively simple. The biodiversity index were rather lower in the commuities sampled. According to the results of the secondary forest community structure in Nanjing, the optimization strategies on the community structure were recommended in the paper.
