Based On The Concept Of "Sponge City" Baiyin Park Green Space Planning Research

With the rapid development of city,the original development concept adopted large-area impervious pavement for urban infrastructure construction.In recent years,with the global warming and the increase of rainwater,due to the extensive development of the city's hydrological system to interrupt the cycle,a series of practices directly lead to frequent urban waterlogging,water resources crisis has become an obstacle to the city.One of the important factors of city development.Water pollution and water shortage restrict the future of urban sustainable development.In view of this reality,“Sponge City” model came into being.The idea is to change the traditional concept of drainage and enhance their ability to regulate and store rainwater.At present,there are still many problems to be discussed in the development of sponge cities.Especially in the Loess Plateau,the water shortage is serious.How to retain and utilize rainwater resources and build sponge cities that meet local needs need need to be carefully considered.Park green space occupies an important proportion in the process of urban green area construction.First,it not only beautifies the city,but also greatly promotes the prevention and improvement of modern urban rainwater and flood.Combined with the construction and management of parks and green spaces in Western countries,it is not difficult to find that the improvement of rainwater and flood management has brought about great changes to cities.Therefore,this paper takes this as a starting point to find new ideas for the construction of sponge cities in arid areas of Northwest China.This paper summarizes the development status of urban rainwater system at home and abroad,and compares the relevant cases of sponge city construction at home and abroad.Based on the theory of sponge city in China,this paper investigates the current situation of park construction in Baiyin City and analyses the current situation of rainwater management.This paper summarizes the existing problems and improvement ideas at the present stage by means of on-the-spot investigation,finds problems in continuous investigation,discusses the current construction progress and problems of Baiyin Park Green Space in the process of investigation,summarizes the distribution characteristics of Baiyin Park and the current situation of rainwater management of green space,and points out the existing rainwater storage of Baiyin Park Green Space.The capacity of rainwater treatment is very limited.From Baiyin City's overall park construction to Jinling Park as the research object,and the planning design method and design points of Baiyin City's park green space are put forward.From the point of view of sponge city construction,combined with the situation of Baiyin city,combined with rainfall,hydrological information and other factors.The existing problems were put forward to construct the sponge system of Baiyin park green space,to enhance the role of park green space in the optimization of urban water ecology,and to solve the water shortage problem in the current urban development process,especially the resources located in the northwest semi-arid region.For a large-scale city,the urban water problem has been restricting the development of the city,so the construction of sponge city is undoubtedly an important measure.Taking this as a breakthrough point and combining with the specific situation of Baiyin park green space,with a view to promoting the construction of “sponge city”in Baiyin,strengthening the attention paid to rain and flood management in the Western water-deficient areas,and providing decision-making reference for promoting the harmonious development of the city is of great necessity and feasibility.
