Research On Optimization Of National Fitness Facilities Allocation In The Central Urban Area Of De’an County From The Perspective Of The Fitness Circle

With the promotion of the Health China strategy,residents’ demand for fitness and exercise is increasing.As a carrier of fitness activities,the scientific and reasonable allocation of national fitness facilities is an important measure to meet residents’ needs and drive national fitness effectively.Federal and local governments have successively proposed to optimize the configuration of facilities by building fitness circles,providing new ideas for optimization around the country.As a basic unit of the national governance system,most counties have been late in responding to the national fitness policy and have not paid enough attention.The lack of systematic planning of related facilities has prevented them from meeting the fitness needs of diverse people.Based on the above,this paper takes the perspective of fitness circle theory.It takes the central city of De’ an County,Jiangxi Province,an empirical case to optimize the configuration of national fitness facilities.The core lies in breaking through the original single method of dividing the hierarchy by administrative boundaries,incorporating the theory of circles,and taking the needs of residents as the primary reference basis for dividing the scale,and on this basis,to study the content of the index control elements,the construction of national fitness facilities is applicable to the county configuration system.To better guide the optimization of facility configuration,improve the satisfaction of residents’ daily fitness,help achieve the construction goal of a better living environment,explore the strategic approach to the design of the county’s national fitness facilities,and provide a valuable reference for achieving accurate and fair allocation of facilities.This paper is divided into three main areas:relevant theories and practical case studies,research on constructing a national fitness facility allocation system from the perspective of fitness circles,and research on empirical case studies and optimization strategies.(1)Relevant theories and practical case studies:through sorting out approaches such as fitness circles,levels of demand and their related research progress at home and abroad on fitness circles and national fitness facilities,summarize the guiding significance for this study.Analysis and study of national and local standards and selected examples of planning practice to clarify the development of trends in the configuration of facilities in China.(2)Research on the construction of national fitness facilities allocation system from the perspective of fitness circles:based on theoretical analysis,combining the results of residents’ behavioral and demand surveys,using travel mode and time duration as the primary definition basis,the fitness circle is divided into three levels:urban fitness circle,extended fitness circle and basic fitness circle,measuring the travel distance and spatial scale of different levels,and establishing the county fitness circle hierarchy;research determines ArcGIS The study determines the time cost distance function in ArcGIS as the delineation method,takes the residential district as the starting point to simulate the isochronous coverage area of residents’ travel for preliminary delineation,and takes into full consideration the population,scale and other factors for secondary correction;under the fitness circle hierarchy,determines the types of facilities as 5 major categories and 17 sub-categories,proposes the graded allocation of facilities,construction scale,land use pattern and other index control elements,and constructs a complete national fitness facility configuration The system will be used to guide the structure of facilities in the county.(3)Empirical case study and optimization strategy research:the analysis of De’an County and the central urban area,taking into account factors such as scale,population and residential location,assesses the current situation and problems of national fitness facilities in the main metropolitan area of De’ an County;divides the different levels of fitness circles in the main metropolitan area of De’ an County according to the delineation method,and optimizes the facilities in the other processes according to the configuration system constructed above,verifies their feasibility,proposes optimization strategies for advocating sharing,supplementing quantity,improving quality and optimizing layout,the final summary of optimisation ideas and strategies based on the views and conclusions developed will serve as a reference for counties of the same size in the central region.
