Study Based On The Spatial Layout And Influencing Factors Of Commercial Gyms In The Main Urban Area Of Kunming Under GIS

Commercial gym is the most important component of urban leisure sports facilities.It is of great significance for adapting to the needs of the whole people's physical exercise venues,improving the people's life happiness index,building a harmonious society,and promoting urban development.However,in recent years,with the acceleration of urbanization process,the urban spatial layout structure of Kunming has also changed day by day.How to adapt the total amount and structure of existing commercial gyms in the main urban area of Kunming to the needs of urbanization and rapid development,so as to meet the growing sports health needs of the public is a key issue in the construction layout of urban sports venues in Kunming.This study uses the data analysis results of commercial gyms in the main urban area of Kunming city and related data analysis obtained by Auto Navi map and POI big data analysis.Focusing on the five major municipal districts of Kunming,namely Xishan District,Wuhua District,Panlong District,Guandu District and Chenggong District.On the basis of statistical analysis of the number of commercial gyms in the main urban area of Kunming,research methods such as literature research method,data analysis method,geographical detector and GIS spatial analysis method were adopted.Analyzing the spatial characteristics of commercial gyms in the main urban area of Kunming,such as spatial agglomeration degree and spatial distribution.The geographic detector model is used to reveal the influencing factors of the spatial distribution of commercial gyms in the main urban area of Kunming.The study shows that the spatial distribution of commercial gyms in the main urban area of Kunming generally shows the structure of "Central Circle + Peripheral Group",and in the spatial distribution,the distribution characteristics of northwest-southeast are generally presented.That is,its spatial distribution shows the characteristics of more north-south distribution and less east-west distribution.It reflects the uneven spatial layout of commercial gyms in the main urban area of Kunming,showing the trend of gradual expansion of the central urban area to the northwest-southeast direction.The population size factor obtained by the geographical detector model is the main factor affecting the spatial layout of commercial gyms in the main urban area of Kunming,and the factor of road network density has a relatively small impact on the spatial layout of commercial gyms in the main urban area of Kunming.There is a clear two-way enhanced interaction relationship between each influencing factor,in which the population size factor and the luminous remote sensing factor interact with each other to achieve the maximum detection factor coefficient.It shows that commercial gyms in the main urban area of Kunming are mainly distributed in areas with large population scale and high urbanization process.In the location of commercial gyms,it is necessary to fully consider the factors of population size,economic development,density of road network,the average distance from the nearest commercial center,the average distance from the nearest place of accommodation,and the average distance from the nearest place of work.
