The Landscape Approaches Of Sponge City Development In Three-dimensional Garden City

Around the world,china is being experienced the fastest urbanization process.Behind the acceleration of urbanization process,a series of urban problems and water problems,such as traffic congestion,land resource shortage,water resource shortage,etc.,are always bothering us.In the city,how to protect the land and water resources has gradually become a hot topic.How to connect the three-dimensional development mode based on the intensive use of land resources with the sponge City focusing on the recycling of water resources is an important research content.In this paper,the three-dimensional garden city and the sponge city construction theory are connected,in order to provide some thinking direction for solving the comprehensive urban problems to a certain extent.First of all,based on the relevant theoretical research of the three-dimensional city and garden city at home and abroad,and combined with the excellent cases at home and abroad,this paper makes a detailed analysis,and extracts the key points of the construction of the three-dimensional garden city.Secondly,this paper combs the related theoretical developments of sponge city construction at home and abroad,analyzes the construction means of landscape approach and rainwater technology facilities of sponge city construction,and summarizes the construction contents and achievements in rainwater utilization.Thirdly,the paper analyzes the rainwater utilization link in the three-dimensional garden city from the existing cases,and puts forward the development and construction goals,construction strategies,construction points and construction principles under the combination of the two theories based on the construction points of three-dimensional garden city and sponge city.To lay a good theoretical foundation for empirical research.Finally,this paper combines the case study of Soochow Yangtze River Delta International R&D community,and introduces the three-dimensional garden city of this case from four angles:three-dimensional corridor,sunken ecological courtyard,landscape architecture and three-dimensional revetment.On this basis,combined with the theoretical knowledge extracted above,he put forward targeted rainwater construction strategies for the site,and analyzed the rainwater utilization strategies and design methods from five aspects of three-dimensional road,three-dimensional barge,building rainwater design,courtyard,green space plan,which provided a certain reference value for the future development and construction of such a new city.
