摘要
通过对广西贵港园博园贵港园中的66个人工植物群落进行样方调查,分析其人工植物群落结构及其多样性特征。结果表明:(1)广西贵港园博园贵港园人工植物群落内共有植物245种,隶属于82科191属236种。乡土树种占优势地位,含多种外来树种,常绿乔木所占比重大,落叶植物无论是在种类还是数量上远远不足;(2)园内植物种类丰富,但其在数量上还是集中于少数植物种类,草本层中马尼拉草占绝对优势地位,杂草的种类及其出现的频次较高;(3)园内植物群落以乔-灌-草此类复合结构为主,不同结构的植物群落的Shannon-Wiener多样性指数与物种丰富度指数成正相关;草本层的物种丰富度指数、Simpson指数、Shannon-Weinner指数以及均匀度Pielou指数的平均值都高于乔木层和灌木层。
Based on the sample survey of 66 artificial plant communities in Guigang Garden of Guangxi Guigang Garden Expo Park,the community structure and diversity of artificial plants were analyzed.The results showed that:(1) There were 245species of artificial plants in Guigang Garden,belonging to 236 species,191 genera and 82 families.Native tree species were dominant,including a variety of introduced and cultivated tree species.Evergreen trees accounted for a significant proportion.Deciduous plants were far from sufficient in both species and quantity.(2) The park was rich in plant species,but the number was concentrated in a few plant species.Manila grass dominated the herbaceous layer,and the species and frequency of weeds were relatively high.(3) The Shannon-Wiener diversity index was positively correlated with species richness of the community with different structures.The average species richness index,Simpson index,Shannon-Weinner index and Pielou index of herb layer were higher than those of tree layer and shrub layer.
