Research Of Urban Sponge Park Based On SWMM Quantitative Analysis:A Case Study Of Xiushui Park In Dingzhou City,Hebei

With the rapid development of cities,many urban problems have emerged,among which the most prominent ones are urban flood disasters and rainwater runoff pollution.At the same time,the sustainable urban construction which pursues the harmonious coexistence between man and nature has become the theme of future urban development.In this process,solving the problems of rain and flood and pollution through urban park green space has become a hot research direction.Combining with the sponge city technology means,exploring the technical landscape design methods not only transforms the city into a green sponge that can adjust the use of water resources,but also greatly improves the quality of urban landscape.On this basis,SWMM is used to model and simulate,and the utility of sponge park is quantitatively analyzed through data charts,so as to guide the design more accurately.Firstly,this paper reviews the development process of domestic and foreign models and software platforms for rainwater management.Then,it analyses the related research results at home and abroad and the related policy orientation in recent years.It summarizes the design points of sponge measures and the accurate calculation of the size of sponge facilities according to the amount of rainwater absorbed.Then the operation principle and parameter setting of SWMM sponge model software are summarized,and the research area is generalized.Then,the relevant cases of sponge park are analyzed,and the landscape treatment methods of sponge technology in park green space are summarized.Finally,the author takes the planning and design of Xiushui Park in Dingzhou City as an example,taking protecting and maintaining river course and urban safety as the primary principle,carrying out landscape design of sponge park on the basis of meeting the basic requirements of design norms and regional culture of urban comprehensive park rationally arranging sponge facilities and carrying out landscape treatment,and fully tapping its humanistic function and cultural charm The economic applicability and sustainability of the heavy projects are analyzed quantitatively based on the SWMM sponge city model.The data show the effectiveness of rain and flood control and pollutant reduction in the sponge park.Make it a landmark landscape space in the south of Dingzhou City.
