The Street Landscape Design Of Kechuang Valley Residential District In Xi’an Fengxi New City Under The Function Of Sponge City

Since the reform and opening up,the rapid development of China’s economy and society,with the continuous progress of urbanization,inevitably caused some ecological problems,such as the shortage of water resources,the decline of groundwater level,waterlogging and so on.In some domestic cities,these problems are more and more serious,hindering the development of the city.Therefore,the central government has determined the overall development framework of "sponge city".The construction of "sponge city" in residential area has been more popular in foreign countries,but the development time in China is relatively short,and there is still a lack of relevant research and successful examples.In most urban residential areas in China,impervious pavement,dense buildings and underground development are common.Urban rainwater often can not infiltrate and can not be used reasonably.Therefore,the construction of "sponge city" in urban residential areas has been paid more and more attention.In this paper,Xi’an Fengxi new town kechuanggu residential area to carry out relevant research,from the perspective of sponge City,on the basis of understanding the basic situation of domestic and foreign residential area design,analyzes the basic theory of sponge City,explores the design scheme of sponge City,and tries to apply the concept of sponge city to the residential area studied in this paper.The work done in this paper will help to realize the long-term development of the residential area,and lay a theoretical foundation for promoting the construction of "sponge city" in urban residential area.The main contents of this paper are as follows: first,on the basis of sorting out the main theoretical data in the field of sponge city at home and abroad,taking typical successful cases as the research object,this paper explores the research progress of sponge city at home and abroad,studies and understands the design scheme of sponge City,analyzes and summarizes it,and accumulates useful experience for the design and construction of the project.Secondly,investigate the situation of kechuanggu residential district in Fengxi new city,and summarize the relevant information after the investigation,and discuss the landscape design method of the residential district by using the existing mature theory.Fourth,the design of sponge City special design,road pavement design,plant design,lighting facilities and other special contents of the site,enrich the basic functions of the residential district,promote the healthy and green development of the District,and promote the construction process of happy community.
