Study On Spatial Distribution And Optimization Strategy Of Xi'an Feng'dong Sports Venues On The Basis Of GIS Technology

Research purposes: The national fitness path is an important part of the urban public sports space.It plays an important role in the smooth implementation of the national fitness program and the improvement of the physical fitness of the whole people.With the increase in the number and size of the national fitness path,the configuration is not The problems of balance,unmanned management and lack of maintenance are also becoming more and more prominent.This paper finds out the problems in the spatial layout of the national fitness path in the new town of Jidong New Town through the study of the spatial layout of the national fitness path in Jidong New Town,and proposes that it is suitable for the fitness of Jidong New City.The development model of the path,in order to provide a theoretical basis for urban planners.Research method: This paper selects the spatial layout of the national fitness path of Qidong New City in Xi'an as the research object,and uses the literature data method,field survey method,GIS spatial analysis method,interdisciplinary cross method and mathematical statistics method to make use of the actual investigation process.The map positioning function accurately records the latitude and longitude of each fitness path,counts the number of fitness equipment,usage,damage,location,and safety management,and takes photos and records of the problematic fitness path;In the GIS spatial analysis method,superposition analysis,interpolation analysis,Thiessen polygon analysis,bearing capacity analysis,network analysis,coverage analysis,and minimum impedance analysis are used to determine the relationship between the national fitness path and residential areas in Jidong New City.The relationship between fitness path and population density,as well as the range of services,service capabilities,accessibility,number of uncovered fitness paths,and number of new fitness paths.Research results: The results are as follows:(1)The spatial distribution of fitness path in Fengdong New Town is obviously consistent with population density and residential areas,but the spatial accessibility is poor as a whole,and the overall layout is clustered.With Jianzhang Road Street and Sanqiao Street as the center,the number from center to periphery decreases gradually,and the service scope of fitness path becomes larger,but the service capacity decreases gradually.(2)Sanqiao Street and Jianzhang Road Street are the old urban areas of Fengdong New Town.They are the population gathering places of Fengdong New Town.The spatial layout of fitness paths is consistent with the distribution of residential areas and population density.The community development is relatively mature.The fitness paths have been put into use earlier,the number is larger,the service scope of fitness paths is small,the space accessibility is strong,and the service ability is good.They can basically meet people's sports needs.The need for exercise.(3)Fengdong Street is dominated by commercial residential buildings and high-tech industries,with less planning of public sports facilities,fewer fitness paths than the number put in,larger service scope of a single construction path,small service capacity,weak accessibility,and the planning and delivery of national fitness paths lag behind the development of urban communities,which can not meet people's needs for physical exercise.(4)Wangsi Street and Doumen Street,35 villages have been demolished due to the construction of beautiful town in Hejing and Kunming Pool Scenic Spot.Although the existing fitness routes have good accessibility,the number of them is small and the service ability is weak,which can not meet the needs of people's physical exercise.Research conclusions:MaxCover model is used to determine 82 uncovered residential areas.Minimize Impedance model is used to plan 55 new fitness paths.The spatial layout patterns of "centralized and decentralized mode" and "waterfront greenway mode" are put forward.The optimization scheme is put forward to make the spatial layout of the national fitness paths in Fengdong New Town more reasonable.It has played a positive role in promoting the implementation of the national fitness program.
