摘要
以群落为单位对云南省个旧市城市绿地进行抽样调查,对建城区五类绿地中的植物群落共抽取101个样本,调查每一群落的物种组成、对每一种植物记录数量、所属层次,统计树种总数和出现频率,最后做出树种出现频率分析、植物群落特征分析和植物群落物种多样性分析。结果表明个旧市城市绿地景观类型单一,植物群落面积小、层次单调,覆盖稀疏。最后根据现状提出建议。
The study is based on the investigation results on vegetation community in the centre district of the city. 101 vegetation communities were selected to investigate. The investigation items include the type and amount of species of each community, and then the frequency of each species is calculated. At last, the analyses on species frequency, vegetation community characteristic and biodiversity have been made. The results showed that there is a lack of optimized combination and biodiversity in the he greenspace system of Gejiu urban area. Then some suggestions were put forward based on the results.
