Based on the POI data of 14 types of public service facilities in the main urban area of Lanzhou in 2022,this paper uses the spatial analysis methods of kernel density analysis and weighted superposition to analyze the matching relationship between residents'demand for public service facilities and the perfection of existing facilities according to the life circle at different spatial scales.The research results show that:The public service facilities in the main urban area of Lanzhou show a zonal distribution characteristics of dense east and sparse west,catering,food,shopping.The tourist attractions and other facilities are clustered in multiple centers;The residents'demand degree and facility per-fection degree in some areas do not match,which is mainly due to the early construction of old residential areas,high population density,high residents'demand degree and low facility perfection degree;The functions of land use have changed.For example,the facilities around the new business district are relatively complete,but there are few resi-dential districts.There is a low demand for residents but a high degree of facility perfection;We can improve the sur-rounding facilities of old communities and build a gathering place of multi center public service facilities to promote the equalization of living service levels in all districts.
