The allocation of urban public service facilities directly affects the well-being of urban residents.Using the analytic hierarchy process and the method of constructing network data model,the living convenience index of the central urban area of Lanzhou is calculated,At the same time,the multi-scale geographically weighted regression model was used to analyze its influencing factors and spatial heterogeneityby taking the central urban area of Lanzhou as an example from the perspective of life circle.The results show that:The overall layout of public service facilities in each district presents a layout mode of good centerand peripheral decrease.From the perspective of the convenience index of urban communities,Xigu District has the highest convenience index,followed by Qilihe Dis-trict,Chengguan District and Anning District.GDP,building density and the shortest distance from the bus are the main factors affecting the convenience of urban community life.The research provides a horizontal comparison for the special planning of public service facilities in various districts as a scientific basis for the layout of public service facil-ities in the central urban area of Lanzhou,which offers reference for similar cities.
