The Research Of Urban Park Planning Based On The Theory Of Sponge City In Zhusanjiao Area

With the acceleration of the urbanization process and the large increase of urban surface runoff,the city has faced a series of practical problems such as flood disaster and lack of water resources.The government put forward the requirement of building sponge city in 2014.The park,as an important green infrastructure,plays an important role in regulating urban climate,improving urban environmental quality and maintaining ecological balance.How to combine the concept of sponge city with the planning and design of urban park and help improve the ability of city to deal with disaster challenge has become the main content of this paper.The paper is divided into four parts:First,the paper analyzes the development trend of sponge city's concept to urban park planning and design by combing the development process of sponge city.Aiming at the construction conditions of sponge city in Guangdong Province,it is found that the sustainable development of the city is facing a serious water crisis.It is pointed out that the design level needs to incorporate the concept of sponge city into the basic link of design.Secondly,based on the concept of sponge city,this paper summarizes the research status of sponge city theory at home and abroad.On the basis of lite rature research,this paper defines the concept of sponge city,low impact development,rainwater garden,re-examines the deep connotation of sponge city,and summarizes the characteristics of sponge city.Combining two typical practice cases,this paper a nalyzes the contents of planning,technology,aesthetic and so on,and sums up the lessons of it in detail.Thirdly,three successful sponge city demonstration projects completed in Guangdong Province were taken as research objects,they were analyzed thro ugh field investigation,data collection.Summarizes the advantages and disadvantages of the existing projects and compares them with the traditional parks under the sponge city theory.Fourthly,the paper elaborates the design strategy and method of the park under the concept of sponge city,and systematically discusses the relatively complete design theory,including planning layout,park vertical design,water system design,vegetation design,pavement and so on,Got the main points of the park planning.Based on the cross-scale ecological planning theory and method system;Through the vertical design to change the surface runoff,to build a landscape efficiency of the runoff control system;Construct ecological model of water system and ecological mana gement of water;Through the reasonable plant configuration to absorb,store and purify the rain;According to the ground function set permeable pavement;Emphasizing the integration of technical facilities and other design elements in the landscape,bringing the design methodology into the integration of science and art.Under the background of sponge city construction,this paper,through the theory and practice of sponge city construction,summarizes and discusses the planning and design procedures and methods of sponge city connotation park,which can make better use of compound function value and social benefit of city park,to create a good urban development environment and living environment.
