Coupling Way Of Sponge Technology Application In Park

Since the reform and opening up,China's urbanization process is accelerating,the city's rain and flood problems.With the continuous deepening of related practices,China is trying to get rid of the plight of traditional stormwater management problems.In this process,the park green space has gradually become one of the carriers.The coupling ways of application of park green space sponge technique proposed in this paper,aiming to further understanding of the transformation of park green space of existing features,explore the method of strengthening the sponge function of urban parks,summarize the application of.So it is helpful to improve the level of human settlements construction in our country.Firstly,this paper reviews the development process of foreign stormwater management model,the relevant research results at home and abroad in recent years,and the relevant policy guidance in recent years.The problems in the construction of sponge sponge city and the application of sponge technology in the park are summarized.The application of sponge technology in the park green space should not affect the original function of the park.In this paper,the coupling way of sponge technology in park green space is discussed.First of all,the paper expounds the general goal and the coupling application principle of complying with the nature,the overall consideration,the goal pluralism and the economic application.Secondly,the index system of controlling the total amount of annual runoff is considered as the primary control target,taking into account the reduction rate of pollutants and the utilization rate of rainwater resources.Third,this paper puts forward the specific design method of sponge technology,summarizes the coupling design process,and puts forward the typical sponge technology combination model.Fourth,from the point of view of universality,lists a number of commonly used single sponge technology facilities.Fifth the evaluation system of coupling effect of sponge technology is put forward.In this paper,taking the ninth Jiangsu Horticultural Exposition Garden as an example,the key points and the process of the application of the sponge technology are illustrated.In order to accurately evaluate the implementation effect,the selection of the eastern entrance area as a typical study area,for different return periods,before and after the study area organized by various sponge facilities,comparative study of rainfall runoff control rate effect,so as to find design problems for different areas are put forward suggestions to optimize the facilities layout of the sponge.Through the research on the coupling path of the park green sponge,in order to broaden the existing cognitive sponge technology and parks,strengthen the rational design of scientific consciousness,promote our country park construction and development,to solve the current application of park green sponge technical problems in a certain extent.
