Research on the Optimal Configuration of Urban Sports Facilities Based on Graded Accessibility:A Case Study of Anning in Lanzhou
Taking Anning of Lanzhou city as an example, using kernel density analysis method and Gaussian two-step mobile search method to analyze the spatial distribution characteristics and accessibility of sports facilities in Anning. At the same time, ArcGIS lo-cation allocation analysis method is used to optimize the allocation of existing sports facilities. The following conclusions are drawn: There are obvious differences in the spatial agglomeration of sports facilities and residential areas, but on the whole, the sports facili-ties are concentrated in the southeast and sparse in the northwest; The spatial coupling between sports facilities and residential areas is poor, and the problem of mismatch is prominent; The 15 minute range of sports facilities covers a wide range, but the accessibility value is not high, and the service capacity of sports facilities is weak; The optimized sports facilities solved the problem that some resi-dential areas could not reach the sports facilities within 15 minutes, and also improved the accessibility value of the sports facilities.
