摘要: 基于西宁市城西区服务业的POI数据,分析城西区服务业总体及分行业POI数据DBSCAN聚类结果,探究城西区服务业空间布局结构及集聚特征,并对不同区域的服务业布局进行对比分析。结果表明,西宁市城西区服务业总体呈现“两点一线”的空间分布特征,以海湖万达广场与力盟商业步行街为2个中心点,主要分布在“两点”连线周围,并以两点为中心集聚,且南北差异明显,传统服务业占比过大;边界点、噪声点分布集中,规律性强,体现出城西区服务业聚集潜力区域;各行服务业虽受不同因素影响,但其集聚特征差异性较小;城西区服务业发展水平低于东部、中部地区,且空间发展不平衡,受交通通达性影响较为明显。

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.

Key words: POI data, service industry, spatial layout, DBSCAN, Chengxi district of Xining city
