Analysis of the Spatio-Temporal Evolution of Urban Sports Service Facilities in the Yangtze River Delta

Abstract

The spatial allocation of urban public sports facilities is critical for ensuring equitable access to basic public services and maintaining urban spatial cohesion. This study examines central cities in the Yangtze River Delta, utilizing Point of Interest (POI) data to characterize urban sports service facilities. Employing methods such as kernel density estimation, the nearest neighbor index, spatial autocorrelation, and coefficient of variation, this study analyzes the spatial aggregation, synergy, and equalization of sports service facilities at the community scale. The findings indicate that: (1) the spatial distribution of sports service facilities within community life circles demonstrates a clustered pattern, forming a concentric core-to-periphery structure, with notable variations in clustering degrees across different cities; (2) synergy among sports service facilities has significantly improved, with the emergence of multiple high-value clusters and low-value dispersions across various cities; and (3) the level of equalization of sports service facilities in community life circles follows the general order of Shanghai > Nanjing > Hangzhou > Hefei. These insights offer valuable guidance for the planning and optimization of urban public sports facilities.
