基于POI数据的西安市城六区便利店空间分布及影响因素研究
A Study on the Spatial Distribution and Influencing Factors of Convenience Stores in the Six Urban Districts of Xi’an City Based on POI Data

便利店作为城市的商业基础设施之一，其空间分布对城市的商业结构具有重要影响。基于西安市城六区便利店的兴趣点(Point of interest, POI)数据，运用核密度估计、标准差椭圆等空间统计的方法，分析了西安市城六区便利店的空间分布及影响因素。结果显示：西安市城六区便利店的空间分布存在不均衡现象，呈现中心城区聚集、周边小范围组团的特点，其空间分布方向为北东–南西，总体较为分散，具有一定方向性；区域内人口密度、人均GDP和道路等级是影响便利店空间分布的重要因素。
Convenience stores, as one of the commercial infrastructure in cities, have a significant impact on their spatial distribution and commercial structure. Based on the Point of Interest (POI) data of convenience stores in the six urban districts of Xi'an city, the spatial distribution and influencing factors of convenience stores in the six urban districts of Xi’an city were analyzed using spatial statistical methods such as kernel density estimation and standard deviation ellipse. The results show that the spatial distribution of convenience stores in the six urban districts of Xi’an City is uneven, showing the characteristics of clustering in the central urban area and small clusters in the surrounding areas. The spatial distribution direction is from northeast to southwest, which is generally scattered and has a certain directionality. The population density, per capita GDP, and road level within a region are important factors affecting the spatial distribution of convenience stores.
