Study On The Design And Reconstruction Of The Small Park Beside The City Street Under The Theory Of Sponge City

With the development of urbanization,the impervious area of urban surface is increasing day by day,which affects the urban water circulation system.The decrease of water circulation system efficiency leads to serious urban waterlogging and shortage of water resources.The concept of sponge city emerges as a new generation of urban rainwater management concept.The construction of sponge city with "natural accumulation,natural infiltration and natural purification" is a new direction of urban planning and development.As the carrier of sponge city construction,the small park beside the city street is an important part of sponge city construction.First of all,through literature research,case study,field research,experience summary and other methods,this paper systematically combs the management methods and theoretical research of domestic and foreign cities to deal with the problem of rain and flood,and analyzes the concept of sponge City,small park beside the street,etc.,and analyzes the relevance of small park and sponge transformation.Secondly,based on the on-the-spot investigation of some street side small parks in Hefei,the paper systematically analyzes the existing problems and deficiencies of rainwater management in Hefei street side small parks.In view of these deficiencies,this paper studies the landscape design strategy of small amusement park,clarifies the design principle and goal of the construction and transformation of small amusement park,analyzes the mode of rain and flood regulation and storage of small amusement park and the strategy of sponge transformation of landscape facilities,and constructs the theoretical method of the landscape design of small amusement park beside the city street under the sponge city theory.Finally,through the case study of small garden at the intersection of Pihe road and Qingyang Road in Shushan District,Hefei City,the possibility of combining the landscape design of small garden with the theory of sponge city is demonstrated.Through the sponge transformation design of small garden,the rainwater regulation and utilization capacity of small garden is improved,which provides feasible strategies and methods for the transformation design of small garden beside the street under the theory of sponge city.
