摘　　要：为了解南宁市体育休闲公园植物群落物种组成及其多样性,使用ArcGIS对南宁市体育休闲公园进行边界划定,采用典型样方法选取样方数量333个,利用植物物种丰富度指数、均匀度指数、重要值以及多样性指数等指标对南宁市体育休闲公园人工绿地植被群落进行调查分析。结果表明:(1)园区内植物种类较为丰富,共有维管束植物241种,隶属于83科184属;(2)公园乡土植物与外来植物之比约为5∶3;(3)群落垂直结构为乔木层、灌木层及草本层,灌木层为优势层;(4)灌木层主要优势植物种群物种多样性较高,Simpson指数为0.9328、Shannon-Weaner指数为3.0562、Pielou均匀度指数为0.9136,物种丰富度与物种多样性无显著相关性;(5)园内各个功能分区植物运用各有特色。针对本次调查结果现状提出3点建议。To understand the species composition and diversity of plant communities in Nanning Sports and leisure parks,ArcGIS was used to delimit the boundary of Nanning sports and leisure parks.Three hundred and thirty-three samples were selected by using the typical sample method.The vegetation community of sports and leisure parks in Nanning city was investigated using the plant species richness index,evenness index,importance value index,and diversity index.The results showed that:(1)there were 241 species of vascular plants belonging to 83 families and 184 genera in the park;(2)the ratio of native plants to exotic plants in the park was about 5:3;(3)the vertical structure of the community consisted of a tree layer,shrub layer,and herb layer,and the shrub layer was the dominant layer;(4)the Simpson index,Shannon-Weaner index,and Pielou evenness index were 0.9328,3.0562,and 0.9136,respectively,and there was no significant correlation between species richness and species diversity;(5)the use of plants in each functional area of the park has its characteristics and put forward three suggestions according to its present situation.
