湛江市城市公园植物群落物种组成及多样性研究

Study on Plant Community Species Composition and Diversity of Urban Park in Zhanjiang City

为了解湛江市城市公园植物群落物种组成及其多样性,采用典型样方法对湛江市4个主要城市公园进行群落调查。结果表明:调查区域内物种较为丰富,共有维管束植物112种,隶属于45科92属,群落结构分为乔木层、灌木层及草本层,乔木层为优势层;群落内植物以常绿阔叶树种为主,少量落叶阔叶树种,尚无针叶树种的应用;乔木层主要优势植物种群物种多样性较高,Simpson指数为0.868、Shannon-Weaner指数为3.422、Brillouin指数为3.157、Pielou均匀度指数为0.811,物种丰富度与物种多样性无显著相关性;提出湛江市城市公园绿地植物选择推荐名录。

In order to reveal the plant species structure and diversity of plant communities in different urban park,the typical sample method was used to investigate the community.The results show that:There are 112 species of vascular plants,belonging to 92 genera,45 families,in the survey area,the community structure is divided into tree layer,shrub layer and herb layer,and the tree layer is the dominant layer;There are a few deciduous broad-leaved species in the community,but no coniferous species;The species diversity of the main dominant plant population in the tree layer is high,Simpson index is 0.868,Shannon weaner index is 3.422,Brillouin index is 3.157,Pielou evenness index is 0.811,there is no significant correlation between species richness and species diversity;Put forward the recommended list of plant selection in Zhanjiang City Park Green Space.
