Research on the Spatial Distribution Characteristics of Life Service Industry in the Main Urban Area of Lanzhou City Based on POI Data
Based on the POI data of the main urban area of Lanzhou City,this paper uses the ArcGIS spatial analy-sis method to discuss the spatial distribution characteristics of the life service industry in the study area.The con-clusions are as follows:① There are obvious regional differences in the spatial distribution of various types of life service facilities in the study area,which are dense in the east and middle,and scattered in the west and south,forming a spatial layout with the"old city"as the core,contiguous clusters,and multi-center development.② The supporting facilities of life service facilities in the central area of Chengguan District of Lanzhou City are relative-ly reasonable,while the supporting facilities of life service facilities in Xigu District,Anning District and Qilihe District are poor and need to be optimized and improved.③ The living and service facilities in the main urban ar-ea of Lanzhou City show a significant northwest-southeast trend due to the influence of topography.④ The spatial distribution of different service industries showed a strong correlation.⑤ The mixing degree of living and service facilities in the main urban area of Lanzhou is generally high because of the topographic characteristics of"two mountains and one river".
