Astudy of Plant Diversity in Elderly Parks in Zhaoqing City
[Objective]The purpose of this study is to analyze the ecological characteristics of plant species composition,community structure,species richness,and plant diversity in Zhaoqing Elderly Park,providing references for the protection of plant diversity and the optimization of plant landscapes in the park.[Method]Taking Zhaoqing Elderly Park as the research object,the species composition was investigated by using the sample method,and the frequency and richness indices were calculated.[Result]There are 103 species of higher plants of 69 families and 94 genera in the park.There are 38 species of arbor plants belonging to 33 genera and 25 families,32 species of shrub plants belonging to 29 genera and 26 families,and 33 species of herbaceous plants belonging to 32 genera and 18 families.[Conclusion]Zhaoqing Elderly Park has a relatively rich variety of plant species and a stable plant community structure.However,the ratio of trees,shrubs,and herbaceous plants in the park is comparable,which is not conducive to the matching of layering and the creation of landscape effects;there are fewer species of herbaceous plants with a single type;there are relatively few colored-leaf tree species,and the seasonal changes are not obvious;there is a lack of subsequent maintenance.The research results have certain reference significance for improving the plant diversity of urban parks.
