Research About Sponge City Technology

Our country is in the phase of rapid development of urbanization,industrialization,urbanization and rapid economic development at high speed,at the same time,we live the earth is a huge change,the rapid increase of impervious surface,destroyed the natural ability to cope with the rain flood drainage system.And,because the city municipal infrastructure is imperfect,and the traditional "fast" as the misconception,lead to many cities in our country is faced with more and more serious flooding problem and with more and more frequent droughts.More and more people realize that how important it is to protect the urban water ecological system.Thus,sponge city construction concept was born.According to the research shows that the developed countries have since the 1970 s have been studied the problem of urban rain flood,study and the introduction of advanced rain flood management idea and technology,to alleviate the urban rain flood problem,sponge of all-round construction of the city,according to the concept of low impact development,explore to adapt to our country’s sustainable urban development the rain flood management method has important practical significance.Sponge urban construction is our country in recent years in cities and towns vigorously advocated in the construction of the development of a new mode of urban construction.How to make the city as a "sponge",the realization of regional and urban rain flood resource utilization,and reduce the harm of flood drought? This article gives some shallow Suggestions.This paper first analyzes the China are now facing severe rain flood problems and their causes,and points out some problems of the urban flood control and management in the rain.Then through related literature review and filing,sponge city,low impact development,elaborates the important concepts related to points Xu Haimian each important part of city construction,and it will rain flood resource utilization is the key.Thesis supported by sponge urban system construction theory,mainly discusses the design method of urban rain flood management system,for the purpose of the design,procedures,flow and the main contents are specified,a set of feasible solutions are put forward.Finally in wenzhou a practice case,details the design based on the current condition of the specific operating mode.
