The high-quality development of new-type urbanization focuses on improving people’s sense of happiness and gain. Increasing public service construction in the 15-minute life circle could effectively improve people’s life satisfaction. According to the requirements of the national “15 minute life circle” construction, using the POI data of Gaode map, using the methods of kernel density estimation, buffer analysis and grid analysis, this paper judges the spatial coverage characteristics of public service facilities in Urumqi, and comprehensively evaluates the spatial matching between residential areas and various facilities. (1) The spatial layout characteristics of different types of basic public service facilities are different, which are not only related to the agglomeration and distribution of residential quarters, but also reflect the attributes of different facilities. (2) The coverage of various basic public service facilities in the residential community’s 15-minute life circle has specific differences. The coverage rate of public transportation trips represented by bus stations is the highest. Supermarkets, fruit and vegetable shops, and barbershops are convenient commercial facilities. The coverage rate of daily service facilities is higher than that of banks, telecommunications, business halls, and other facilities. The kindergarten coverage rate in educational facilities is the highest, followed by primary schools, and the coverage rate in middle schools is low. The coverage rate of medical facilities is insignificantly different among several types, and health service centers, pharmacies, and clinics can achieve a 95% coverage. (3) There are obvious regional differences in the compliance rates of various basic public services and residential space allocation. In densely populated areas, the proportion of residential areas is high where public service facilities, such as convenience business, education, medical care, and transportation meet the standards, and the compliance rate of peripheral areas with relatively low population densities and new urban medical and convenience commercial facilities is low. (4) Constructing a 15-minute life circle in Urumqi should focus on strengthening public service facilities in newly built urban areas, especially convenience businesses and primary-level medical facilities. Old urban areas should strengthen public service by updating facilities during the transformation process.
