The new people-oriented urbanization model prioritizes residents’ needs as its cornerstone, aiming to enhance urban development quality, promote equitable public services, and achieve harmonious coexistence between cities and inhabitants. This study investigates the spatial distribution patterns and influencing factors of public service facilities in Hongta District, Yuxi City, utilizing 19,953 POI data points from 2022. Through kernel density estimation, cumulative opportunity accessibility analysis, and geographic detector modeling, we examined the facilities’ quantity, spatial arrangement, accessibility, and their relationships with population size, transportation connectivity, terrain, and economic development. Key findings reveal: (1) The spatial distribution of public service facilities in Hongta District is unbalanced, presenting a “core-periphery-edge” spatial pattern. The urban basin areas of Yuxing Subdistrict, Yudai Subdistrict, and Fenghuang Subdistrict form the high-density agglomeration “core” of public service facilities, while the higher-elevation Luohexiang and Xiaoshiqiaoxiang become the “edge” areas with relatively sparse facility distribution. This distribution pattern is highly consistent with the spatial patterns of population density and transportation networks; (2) There are differences in the supply of different types of facilities. The supply of social security and employment facilities is insufficient, with a total of only 42 in the whole district, far lower than the number of other types of facilities; (3) Social security and employment facilities are difficult for residents to access, with an accessibility index of only 2.44%. The accessibility index of infrastructure is relatively high, but still 87.46% of the study units face the %K 公共服务设施， %K 空间特征， %K 影响因素， %K 玉溪市红塔区
