Study On Sponge Facility Layout In Shenbei New Area Based On Rainwater Resources Utilization

Rainwater,as an important component of urban water resources,plays an important role in the process of natural water circulation.However,due to the accelerated process of urbanization,the intensity of development for the city is also increasing year by year,the original permeability of the natural surface of the underlying surface was gradually replaced by hardening,destruction of a healthy and healthy water cycle process,resulting in urban climate and hydrological environment A huge change,resulting in frequent waterlogging,water shortages,water pollution and a series of water problems.The traditional rainwater infrastructure to take the fast row of the model,has been unable to solve the urban development of the rain and flood problems,and even has become one of the factors that interfere with urban hydrological and ecological systems.Sponge city is the reform of the traditional rainwater management concept,to promote the use of rainwater to simulate the natural storage and infiltration process of rain and flood management,the use of rainwater resources.This paper summarizes the concept of urban sponge facility and sponge city construction research,and combines the purpose of rainwater resource utilization to classify sponge facilities.According to the outline of sponge city planning,according to the status quo analysis-problem identification and demand analysis-construction goals-system construction-the overall layout of the logic of the study.Based on the current situation research and data analysis,this paper analyzes the present situation of rainwater at the macro and micro levels,and summarizes the ways and strategies of regional rainwater resource utilization according to the demand of sponge facilities in different urban functional areas.According to the principle of facility selection andthe principle of layout,the factors affecting the construction of sponge facilities in the area are analyzed,and the plan of sponge facility layout planning is constructed by summing up the construction and construction of sponge facility system in the study area.Finally,with the analysis of GIS topographic analysis and catchment analysis,combined with different urban functional areas for the overall layout planning,and finally summarize the sponge facilities layout structure and techniques,and Xinchengzi New City as an example,at the micro level of concrete facilities.Based on the layout planning and reconstruction of the sponge facilities in Shenbei New Area,this paper aims to construct the rainwater intercepting system,such as green space,water system and residence,to construct the whole regional rainwater intercepting system,realize the regional rainwater accumulation and combine to solve the rainwater problem in the area,Construction of special planning to provide a reference.
