Research On The Application Of Garden Plants In Sponge City In Southern Jiangsu And Shanghai

The rapid urbanization of China in the past three decades,accumulated a lot of urban ecological problems.The urban underlying surface is hardened due to urban expansion that does not follow natural laws,which results in a reduction of urban natural green space.Infiltration under water is hindered.The urban water circulation system was severely damaged.In this context,the state proposed guidelines for the construction of "sponge cities." Plants are one of the most important components of the entire ecosystem.They play a pivotal role in the construction of ecological cities and environmental protection.This article takes southern Jiangsu and Shanghai as examples,from the perspective of a more scientific and effective construction of a sponge city.Reference plant data(China Flora,Jiangsu Flora,Shanghai Flora,Jiangsu Ornamental Plant Resources,Landscaping Plants in Jiangsu Province,etc.),Based on the principles of urban ecology,plant community science,a:nd landscape aesthetics,combined with field research,literature review,and experimental research methods,a list of suitable tree species for sponge city construction in the region was screened out for the current construction of sponge cities and urban biodiversity.Improve the sex for reference.In the aspect of spongy urban plant landscape design,this article focuses on the study of the plant landscape design of sponge city based on biodiversity conservation and the method and model of plant landscape design of green sponge infrastructure on a micro scale.According to research,the type of sponge green plant community under construction is single,and according to the planting conditions of different green sponge facilities(rain garden,undergrowth green land,grass shallow ditch,constructed wetland and biological purification pool,roof garden),the article concludes that the area The type of the best landscape plant community,the comprehensive use of the results of the plant screening in Chapter 3,and the establishment of a plant community model.Provide reference for plant design in the construction of green infrastructure in sponge cities in southern Jiangsu and Shanghai.Finally,based on previous plant selection and basic research on plant landscape design,sponge green infrastructure planning and plant landscape design were carried out in the Yucheng district on the eastern bank of the experimental area located in the city of Lincheng in Shanghai’s Lingang New City.Through the completion of the project,the process model of plant landscape design based on biodiversity conservation in the reconstruction of sponge city was summarized.
