呼和浩特市区餐饮设施时空分布格局研究

Study on Spatial and Temporal Distribution Pattern of Restaurant Facilities in Hohhot

摘要: 城市餐饮设施空间格局研究对城市规划及城市可持续发展具有重要意义。本文以2018年和2021年呼和浩特市区餐饮POI数据为基础，运用核密度估计、最近邻指数、标准差椭圆等方法对2018年和2021年餐饮设施整体及分类餐饮的时空布局特征进行分析，并利用地理探测器进一步探讨其空间布局的影响因素。研究结果显示：1) 2018年和2021年呼和浩特市区餐饮设施整体呈现“多核”的空间分布模式，具有显著的空间集聚特征，且2021年集聚程度降低。2) 2018年和2021年各类餐饮设施空间集聚特征显著，但存在差异，2021年各类餐饮设施核密度峰值均出现减小，且分布范围均出现扩大现象。3) 人口规模、住宿服务、大型购物场所是餐饮设施布局分异的主导因子。

Abstract: The study of the spatial pattern of urban catering facilities is of great significance to urban planning and sustainable development. Based on the POI data of restaurants in Hohhot in 2018 and 2021, this paper analyzes the spatial and temporal layout characteristics of the overall catering facilities and classified catering facilities in 2018 and 2021 by using kernel density estimation, nearest neighbor index and standard deviation ellipse, and further explores the influencing factors of their spatial layout by using geographic detectors. The results showed that: 1) In 2018 and 2021, the dining facilities in urban Hohhot showed a “multi-core” spatial distribution pattern, with significant spatial agglomeration characteristics, and the agglomeration degree decreased in 2021. 2) The spatial agglomeration characteristics of all types of catering facilities were significant in 2018 and 2021, but there were differences. In 2021, the peak nuclear density of all types of catering facilities decreased and their distribution ranges expanded. 3) Population size, accommodation service and large shopping places are the main factors for the distribution of catering facilities.
