南京仙林地区安置小区木本植物组成与多样性分析

Analysis on Composition and Diversity of Woody Plants in Nanjing Xianlin Resettlement Community

对南京仙林地区12个安置小区的木本植物随机分层抽样调查,利用频度、多度及物种多样性指数对调查结果作分析研究。结果表明:12个安置小区乔木层和灌木层的物种组成简单,以常见的园林栽培植物为主,香樟、桂花、海桐和冬青卫矛有较大的优势,整体物种相似性水平为0. 41,物种多样性偏低。改善小区物种组成、提升物种多样性、加强绿化景观维护与建设是管理者后期应重点关注的问题。

The frequency, abundance and species diversity index of woody plants in 12 resettlement communities in Xianlin Nanjing were investigated by randomly stratified sampling method. Results showed that the species composition of tree layer and shrub layer were simple. Common garden plants were the majority, such as Cinnamomum camphora, Osmanthus fragrans, Pittosporum tobira and Euonymus japonicus . The whole species similarity was 0.41, indicating the low species diversity. Therefore, the administrators should pay more attention to improving the species composition in the communities, increasing species diversity, and strengthening the maintenance and construction of greenery landscape in the future work.
