Investigation And Study Of Artificial Plant Community Landscape In Shimen Park,Nanning City

Nanning Shimen Park is a comprehensive municipal park that is based on protecting the natural ecological resources of forest parks and providing residents with a combination of "rest,leisure,and physical fitness".After years of construction,Shimen Park has become a relatively complete urban comprehensive park.However,whether the construction of Shimen park’s artificial plant communities is scientific and reasonable,and whether it can coexist harmoniously with natural forest communities requires relevant verification.How to development a scientific and ecological artificial plant communities and plant landscapes is an momentous element for advancing the level of urban park green space landscape.This article adopts methods such as field survey,literature reading,and data statistics,this paper takes the artificial plant community within the red line of Shimen Park in Nanning as the research object,community species diversity characteristics,and the landscape of the artificial plant community,and proposes the advantages and disadvantages of the explored artificial plant community and optimization suggestions.The results of the survey are as follows:(1)In terms of community species composition characteristics in Shimen Park,a total of 301 species(including autophytes)belonging to 205 genera,88 families were recorded in the artificial plant community sample plot of Shimen Park in Nanning City,with the number of angiosperms,gymnosperms,and ferns=285:7:9;The dominant species of plants are mainly evergreen plants,with the ratio of evergreen plants to deciduous plants being 5.84:1.The dominant species of plants are concentrated in monoecious and oligoecious families;The main ornamental type of plants is foliage plants,accounting for86.4%,followed by flowering plants.The application of native and exotic tree species to plants is relatively balanced,and there are a certain number of invasive species in native herbaceous plants.Dense forests account for 52.8%of the plant community canopy density.(2)In terms of structural characteristics of plant communities in Shimen Park,the structural types of artificial plant communities in Shimen Park include a complete composite structure of "arbor,shrub,and grass",a two-layer structure of "arbor,shrub,and grass",and a single layer structure of "grass".The dominant vertical structure is "arbor,shrub,and grass".The types of artificial plant communities in Shimen Park are divided into patch and block,building surroundings,street trees,hygrophytes,and aquatic plant communities.It is found that the type of patch and block communities is absolutely dominant,with only one aquatic plant community.(3)Species diversity of Shimen Park,the richness of species diversity mainly depends on the vertical structure: the vertical structure of "arbor shrub grass" is the most abundant,and the worst vertical structure is the single layer structure of "grass";In different land types,species diversity is more abundant in patches,and aquatic plant communities are the worst;The order of species diversity at the plant level is: herb layer>shrub layer>tree layer;Among the functional zones,the Central Lake Scenic Area has the richest species diversity.(4)It is found that the plant allocation in Shimen Park is mainly natural,and in view of the shortcomings found in Shimen Park,such as monotonous landscape of artificial plant communities,poor park management,resulting in the flourishing of autophytic plants,and improper handling of invasive plants,it is proposed to appropriately increase aquatic,wet,and color leaf plants on the basis of integrating existing plant resources to improve the color landscape of plants.The park reasonably formulates relevant systems to manage self-growing plants;Increase the intensity of inspections and learn optimization suggestions such as treatment methods for invasive plants.This study analyzes the relevant characteristics of the artificial plant community in Shimen Park in Nanning from many aspects,which provides theoretical and case reference for the construction of scientific and ecological artificial plant community in Nanning City Park.
