Analysis on Spatial Distribution and Influencing Factors of Local Characteristic Catering Industry in Hohhot Based on POI Data

摘要: 基于呼和浩特市主城区的POI数据，利用ArcGIS软件，运用标准差椭圆法和核密度分析法对呼和浩特市主城区地方特色餐饮业的空间分布总体特征以及影响因素进行分析，研究结果表明：呼和浩特市主城区地方特色餐饮业的空间分布整体呈现出“东–西”方向延伸的空间分布特征；地方特色餐饮业在其中心地区分布较为密集，分布密度由中心地区向外围地区逐渐递减；主城区地方特色餐饮业的核密度分布具有五个集聚中心，其中集聚程度较高的一个中心即核密度值最高的中心位于新城区，其次是赛罕区、玉泉区，回民区地方特色餐饮业的分布则无明显的集聚中心，呈现出不均衡分布的特征；地方特色餐饮业的分布主要受到人口密度、交通条件以及消费群体及其习惯等的影响。

Abstract: Based on the POI data of the main urban area of Hohhot, this paper analyzes the overall spatial distribution characteristics and influencing factors of the local characteristic catering industry in the main urban area of Hohhot by using the standard deviation ellipse method and kernel density analysis method with ArcGIS software. The research results show that the spatial distribution of the local characteristic catering industry in the main urban area of Hohhot generally presents the spatial distribution characteristics extending in the “East-West” direction. The local characteristic catering industry is densely distributed in the central area, and the distribution density gradually decreases from the central area to the peripheral areas. The core density distribution of the local characteristic catering industry in the main urban area has five concentration centers, of which the center with the highest core density is located in the new urban area, followed by Saihan District and Yuquan District. The distribution of the local characteristic catering industry in the Hui District has no obvious concentration center, showing the characteristics of uneven distribution. The comprehensive analysis results show that the distribution of local characteristic catering industry is affected by population, transportation and consumer groups to varying degrees.
