Study On Evaluation And Promotion Strategy Of Supply Level Of Urban Public Open Space In Changsha City

Public open space is the main place for residents’ outdoor activities,communication and rest,which provides a series of benefits including social benefits,ecological security benefits and economic benefits.However,the contradiction between supply and demand of public open space is becoming more and more serious due to the economic development rather than social benefits,the financial pressure of local governments,the poor connection between related functional departments and the fuzzy functional boundaries.To this problem,the CPC Central Committee of our country attaches great importance to it,and puts forward the guiding principles of increasing public open space and solving the shortage of supply.It can be said that how to better meet people’s increasing demand for public open space has become an urgent requirement of modern governance reform.The existing research on supply mainly focuses on the development mode of private public space and its policy recommendations,while the research on the supply of public open space is basically blank.Based on this,the main focus of this paper is:What is the actual supply level of the existing urban public open space in Changsha under the premise of distinguishing the traditional quantitative evaluation method of indicators? What is the cause of the result? What are the corresponding governance strategies? With these problems in mind,this paper considers the governance framework to improve the supply level of public open space in Changsha.Firstly,this paper defines the concept of public open space,and introduces the research progress and theoretical basis of public open space supply at home and abroad.Secondly,it discusses the contradiction between supply and demand in Changsha public open space,and clarifies the significance of evaluating the actual supply level.Then,on the basis of combing and analyzing the existing evaluation methods of supply level of Changsha public open space,it puts forward quantitative evaluation methods of supply level and residents’ perception evaluation methods that can reflect both spatial attributes and socio-economic attributes,and evaluates and summarizes the current situation of its supply level from street level and community level.Thirdly,based on the design,development,use and management process continuum proposed by Carmona’s urban design process theory,taking London and Melbourne as application cases,this paper combs and summarizes the key elements of shaping and reshaping the public open space.On this basis,combined with the actual situation in Changsha,it constructs a three-dimensional analysis framework of material shaping,social class and management system to analyze the causes of supply status;Finally,aiming at these three causes,based on the theory of multiple supply and coordinated governance,this paper constructs a strategic framework for improving the supply level of public open space,in order to provide some reference and inspiration for the planning,construction,management and maintenance of public open space in China in the future.
