Abstract Based on the perspective of living circles, this paper analyzes the spatial allocation of public service facilities and puts forward the planning scheme of facility layout, which is not only conducive to the realization of spatial justice of public service allocation, but also a positive response to the development concept of "people's cities for the people". Based on the perspective of living circles and taking the downtown area of Hefei as an example, this paper first explores the distribution patterns and supply levels of public service facilities by means of kernel density analysis and network analysis and, in turn, analyzes the matching between public service facilities and the distribution of population. Finally, the planning path of facility configuration is proposed based on the location-allocation model (L-A). The study shows that:1) All kinds of facilities present a core-edge spatial distribution pattern and saliently differentiated layers of distribution, and there are obvious differences between the spatial agglomeration levels of inter-regional and different types of service facilities; 2) The coverage rates of facilities varies significantly among different residential areas, and the scope of coverage is generally small. 3) There are significant spatial differences in the adaptability of public service facilities in the living circles in different regions, and the proportion of adaptable living circles for the overall four types of facilities is not high; 4) Based on the minimization facility model, the spatial configuration scheme of various facilities is calculated and simulated
