Planning And Construction Strategy Of "sponge City" Under The Urban Spatial Scale In Guangzhou

At present,China put forward the "ecological environment to accelerate the padded short board as the core task of 13 th Five-Year" period,the protection of the ecological environment,and the 19 th CPC National Congress is clearly Chinese open a new era of ecological civilization construction."Sponge city"construction as a filling one of the important measures for ecological environment short board,also opens the door to the new era ecological civilization construction of the golden key,by the state council and the strong support of the relevant ministries and commissions of the state.The "sponge city" has broken the traditional flood control methods and exerts the advantages of low impact development to protect the ecological environment of the city.However,due to the different natural conditions and social development in China,the low impact of single micro-site scale has little effect on development.Therefore,the space of city construction focus on the key technology of sponge and targeted in the urban spatial scale point of view,put forward "sponge city construction strategy,provide an effective way for the implementation of the implementation of the sponge city concept,has become the research advocated by the starting point.This paper first introduces the related concepts of the spatial scale of the city and the spongy city,and studies the theoretical development of the spongy cities at home and abroad.Then,through the case study of related construction practices in some developed countries in Europe and the United States,we can compare the current progress and shortages of related theories and practices of sponge city construction in China,and put forward references to foreign experiences.Subsequently,taking the representative city Guangzhou as an example,this paper analyzes its natural geographical conditions,urban construction and urban spatial system.At the same time,it also studies the current situation of the construction of "sponge city" in Guangzhou,and analyzes the current construction problems.On this basis,this paper discusses the general goal,construction concept and construction principles of sponge city construction from the perspective of urban material space,and constructs a framework system.In the system,this paper focuses on the analysis and study of the city level and the urban level,and puts forward the strategy of "sponge city" in the urban space scale.The above strategy also takes the related construction of Guangzhou as an example to demonstrate that it has some practical significance.Finally,this paper discusses the guarantee mechanism of the construction of "sponge city" in the urban space scale,and summarizes the relevant methods.
