Investigation On Artificial Plant Community In Nanning Sports Leisure Park

The concept of"Sports park"was proposed in China since the 1990s,and"Sports Leisure park"is an important component of it.As a carrier to improve the quality of life and enhance people’s sense of ecological environment,its good development is crucial for the construction of China’s urban green space system.The planning and configuration of artificial plant communities in Sports parks greatly affect their function,and is the key to improving the plant landscape of urban green land.Based on the preliminary investigation,the park was divided into nine functional zones.Used various research methods,the species composition,quantitative characteristics,and species diversity of artificial plant communities within the design red line of Nanning Sports Leisure Park were quantitatively studied.Analysed the configuration mode and landscape status quo,and proposed suggestions for problems.The findings were as follows:(1)A total of 241 species(including native species)of vascular plants belonged to 83 families,185 genera,were investigated in the sample plots of artificial plant communities in Nanning Sports Leisure Park,with angiosperms as the main species,and the autogenous plants were mainly herbaceous plants.Life type:the ratio of woody to herbaceous plants was about 9:7;The ratio of evergreen to deciduous plants in woody plants was approximately 22:5.Ornamental characteristics:mainly foliage and flowering plants.Species origin:There were many alien in cultivated plants.(2)The dominant species in the arbor layer of Nanning Sports Leisure Park were Banyan,no dominant plants in the shrub layer,and Zoysia Matrella Merr was the dominant species in the herb layer.The application difference of arbor layer was the highest,followed by shrub layer,and herb layer had the least difference.(3)In terms of horizontal structure,the DBH of tree species in Nanning Sports Leisure Park was mainly concentrated in 5-15cm;The horizontal density of trees and shrubs in the artificial plant community was 0.0526plants/m~2,with a reasonable density.Divided the artificial plant community into six vertical structure types,among which"arbor shrub grass","arbor grass",and"shrub grass"were the main types.(4)The diversity of shrub layer was the highest and that of arbor layer was the lowest in Nanning Sports Leisure Park.The diversity of"arbor shrub grass"was the highest,and the diversity of"arbor"was the lowest.Among the different site locations,the diversity of moist community was the highest,and that of street tree community was the lowest.From the perspective of zoning,the diversity of Turf Sports area was the highest,and the diversity of Hiking Trail area was the lowest except for Other areas.(5)In terms of plant configuration pattern and plant landscape.It was concluded that the artificial plant communities in Nanning Sports Leisure park could be divided into three basic configuration patterns and six specific configuration combinations.Analyzed the differences of plant landscape in different functional zones.(6)For some plant groups,there are few plant species;Native plants are less commonly used in plant applications;Poor coordination between plants and other garden elements;The lack of cultural charm of plants and the lack of conservation management put forward the idea of increasing the use of herbs,lianas,gymnosperms,increasing the use of aquatic plant,and deepening the rainwater garden landscape;Increase the variety and application of local plants;Explore the cultural characteristics of plant landscapes;Suggestions for coordinating the relationship between plants and various garden elements and strengthening maintenance management.
