Research On The Reconstruction Of Existing Urban Parks In Shijiazhuang City Based On Sponge City Theory

With the continuous development of cities,the construction of sponge city is a more appropriate way to solve the existing precipitation problem.Rainwater garden,as an important part of it,is popular because of its easy setup and good effect,and is widely used in design or transformation.With the continuous development of society and the increasingly serious environmental problems,the number and intensity of extreme weather are increasing year by year.Recently,the city’s adaptability to the environment has gradually been unable to overcome the increasingly severe extreme weather.In this paper,the existing urban park reconstruction case is studied,that is,the existing urban park reconstruction based on the sponge city theory,to ensure that the effect of rainwater treatment is achieved while minimizing the negative impact.The ultimate goal is to improve the landscape quality of urban parks and to improve the city’s response to extreme weather.Under the background of constructing sponge city system,our country is influenced and guided by the theory of low-impact development.Landscape design based on this theory will be conducive to the improvement of urban habitat,the collection of rainwater resources and the use of municipal irrigation,and ultimately realize the common development of man and nature.In practical sense,the renovation of the city parks which have been built for a long time will be helpful to improve the freshness of the city,the quality of the landscape and the ability of rainwater management.By means of data processing,case analysis and field investigation,this paper analyses the general situation of the transformation and development of sponge cities at home and abroad,as well as the classical cases of transformation and design at home and abroad,and draws lessons from the research results in related fields and the successful examples of the construction of sponge city parks in China,classifies and summarizes the actual situation from four aspects: topography,water body,architecture and plants.The methods,measures and plant allocation of rainwater landscape design for urban parks in Shijiazhuang city are summarized.By reading the literature and combining with the current situation of urban park reconstruction at home and abroad,this paper summarizes the application of sponge city theory in urban park reconstruction.In the process of investigation and research,the problems encountered in the use of existing urban parks in Shijiazhuang City were found,and solutions were sought.At the same time,it classifies the current situation of Shijiazhuang City Park,and finds out the suitable transformation method for Shijiazhuang City’s existing city park.Then through the analysis of the composition of the relevant elements of urban parks,we can find a feasible and suitable landscape upgrading application method for Shijiazhuang City Park transformation.Finally,the method of urban park reconstruction can be divided into four categories by dividing the elements,namely,terrain and drainage,water body and purification,building and construction,green space and vegetation.Analyse and adjust the topography properly,retain the existing topography and landforms reasonably,use local materials to transform the park as far as possible,retain the original excellent plants and promote local plants as far as possible,with the purpose of creating the landscapes,while retaining historical relics to stimulate the construction of the park’s cultural level heritage landscape.Applying these methods reasonably to the elements of urban parks,the transformation methods applicable to the four elements of topography and drainage,water body,building structures,green space and vegetation are summarized.It is hoped that through this study on the transformation of Shijiazhuang urban parks,it will be helpful to the transformation of existing urban parks in modern cities.
