摘　　要：采用典型抽样法,对咸宁市城区绿地植物的树种组成、物种多样性及群落层间多样性指数等进行调查统计及比较分析。结果表明,咸宁市城区园林绿化植物共有75科133属197种;各种绿地类型中桂花出现频度最高,其他乡土树种则比较少见;街头公园多样性指数最高,道路绿地、广场绿地、居住区绿地等植物多样性指数较低。咸宁市绿地建设应注意保护街头公园植物的多样性,并进一步优化其植物配置结构,同时应大力增加其他三类绿地植物,重视具有观赏性的乡土树种资源在城区园林绿化中的推广应用。The typical sampling method was used to make a statistical investigation and comparative analysis of the plants composition, species diversity and community diversity index in the urban greenbelts of Xianning city. The results showed that there were 75 families, 133 genera and 197 species of green plants in the urban green lands of Xianning city. In different types of greenbelts, the sweet olives had the highest occurrence, while the other native tree species were relatively rare. The street parks had the highest plant diversity index, while the plant diversity indexes in road greenbelts, square greenbelts, and residential area greenbelts were relatively low. During the greenbelt construction in Xianning city, it is important to protect the plant diversity in street parks and further to optimize their plant composition structures. In addition, it is necessary to increase the plant species in the other three types of greenbelts and attention should be focused on the promotion and cultivation of some ornamental plants in the urban greenbelts.
