广东理工学院鼎湖校区植物群落多样性研究

Study on Plant Community Diversity in Dinghu Campus of Guangdong University of Technology

以广东理工学院鼎湖校区为研究对象,运用典型性抽样法对校园绿地植物多样性、植物组成、植物群落类型进行调查和分析。经调查校区共有园林植物19科21属21种,其中乔木15种,灌木4种,草本2种。绿地植物群落的Margalef指数、Simpson多样性指数、Shanon-Wiener多样性指数、Pielou均匀度指数的数值都处于较低水平。校区植物种类偏少,植物群落结构单一,其中乔木结构占比62.5%,乔灌木结构占比25%,乔灌草结构占比12.5%。该研究结果为校园绿地植物多样性的提升和植物景观建设水平的提高提供切实可行的参考依据。

Taking the Dinghu Campus of Guangdong University of Technology as the research object,the typical sampling method was used to investigate and analyze the plant diversity,composition,and community types of campus green spaces.After investigation,there are a total of 19 families,21 genera,and 21 species of garden plants in the campus,including 15 species of trees,4 species of shrubs,and 2 species of herbs.Margalef index,Simpson Diversity index,Shanon Wiener Diversity index and Pielou evenness index of green space plant community are all at a low level.The campus has relatively few plant species and a single plant community structure,with tree structure accounting for 62.5%,tree shrub structure accounting for 25%,and tree shrub grass structure accounting for 12.5%.The research results provide practical and feasible reference basis for the improvement of plant diversity in campus green spaces and the improvement of plant landscape construction level.
