Application Of Sponge City Theory In Landscape Design Of Urban Interchange

Guanting highway landscape greening improvement can not only bring very good social benefits to the region,also can maintain the peace and stability of the ecology,has the necessity and importance of the construction.Guanting interchange is located in Xi'an,China,the city belongs to the arid and semi-arid regions,on water resources use more constraints,and green on the transformation of the Guanting interchange to want to achieve success,we must take into consideration of the problems of water resources in the area.In the process of continuous development of Xi'an City,a variety of factors led to the emergence of the urban waterlogging and pollution of the water resources is deepening day by day,in the dry season will shortage of water resources,has a great negative impact on the effect of green transformation.To the green transformation can maximize play its role,we must introduce sponge urban concept,the sponge and greening the city transformation combined,together to complete the task of construction of Guanting interchange landscape.Sponge city and low impact development can not be separated,under the idea of the role,development,the hydrological characteristics are not appeared big fluctuations,but urban waterlogging and stormwater runoff pollution and other issues will be addressed.There are a lot of related technologies in the sponge City,including the green roof and so on,respectively,for different direction of the problem.The technology direction as the criteria for classification,sponge city in order to infiltrate technology,storage technology,transmission technology,regulating technology and sewage purification technology of five,and a certain degree of,which mainly introduces the permeable pavement,grass ditch and so on several measures.This paper analyzes and compares the development of sponge cities at home and abroad,and discusses the development of LID technology at home and abroad,and get a lot of relevant experience.After the actual analysis of the Guanting interchange proposed adding the necessity and importance of the concept of urban sponge in Guanting interchange landscape,and has carried on the analysis to the related technical measures and feasibility.In Guanting highway landscape construction,mainly as sink type green space,combined with other related low impact measures,the final completion of task of sponge city construction in this region.Analysis on the design principle and the feasibility of the design,we come to a conclusion,sponge city theory is applied in the city intersection landscape design can solve problem of urban waterlogging to a great extent,and brings the benefit of society,economy and other aspects.
