Abstract: Based on the POI data of the service industry in Chengxi district of Xining city, this study analyzed the DBSCAN clustering results of the overall and sub industry POI data of the service industry in Chengxi district, explored the spatial layout structure and clustering characteristics of the service industry in Chengxi district, and maked a comparative analysis of the layout of the service industry in different regions. The results show that the service industry of Chengxi district of Xining city generally presents the spatial distribution characteristics of “two points and one line”, with Haihu Wanda Plaza and Limeng Commercial Pedestrian Street as the two central points, mainly distributes around the “two points” line, two points are the central agglomeration, and the difference between north and south is obvious, and the proportion of traditional service industry is too large. The distribution of boundary points and noise points is centralized and regular, which shows the potential area of service industry accumulation in Chengxi district. Although the service industry of all walks of life are affected by different factors, its agglomeration characteristics have little difference.The development level of the service industry in the Chengxi district is lower than that in the eastern and central regions, and the spatial development is unbalanced, which is significantly affected by the accessibility of transportation.
