Study on Spatial Allocation of Public Sports Facilities in Beijing at Residential Community Scale

The distribution characteristics, accessibility, fairness, and other spatial configuration of urban public sports facilities are directly related to the equality of basic public services and the integrity of urban spatial structure. Taking Beijing as an example, this paper uses POI data to characterize urban public sports facilities, and uses kernel density estimation, nearest neighbor index, improved two- step mobile search method, and coverage index analysis methods to study the spatial agglomeration characteristics of urban public sports facilities at the street scale in Beijing, as well as the accessibility and fairness from the perspective of supply and demand. The results show that: (1) The improved two-step mobile search method considers the supply scale of public sports facilities at different levels of cities and the travel distance of residents under the concept of "15-min life circle", which is suitable for the accessibility analysis of block level and community level sports facilities. The spatial accessibility of block level and community level facilities in central urban areas is higher; (2) There is a significant spatial agglomeration trend of public sports facilities at all levels in Beijing. The block-level facilities show a trend of "point-like agglomeration and area-like dispersion", and the district-level facilities show a "core-edge" pattern, with more facilities in the central city and less in the surrounding areas. Community-level facilities are in the mode of "small agglomeration and large dispersion", with a uniform spatial distribution; (3) There are many streets with high coverage of public sports facilities at the community level in Beijing, and the spatial allocation is well balanced. There are few streets with high coverage index of public sports facilities at the block level, and the coverage is relatively limited. The results can provide reference for the planning and optimization of public sports facilities in Beijing. © 2024 Science Press. All rights reserved.
