基于POI数据的福州市零售业空间热点时空演变过程研究

POI-Based Analysis on Spatial and Temporal Evolution of Retail’s Hotspots in Fuzhou

摘要: 本文以零售业兴趣点POI (Point of Interest)数据为研究对象，利用核密度估计法提取福州市零售商业中心分布特征，比较不同零售业态布局的差异，运用Getis-Ord Gi*指数法识别零售业的热点地区。研究表明：福州市零售业中心呈多中心发展格局，不同业态区位选择差异明显，高低(HL)或低高(LH)集聚的显著性热点范围呈扩大趋势，总体呈由西向东、由北向南扩张的空间演变态势。文章拓展了POI数据在新时期城乡规划研究中的应用，可助力提升城市商业设施规划的合理性和零售商选址的科学性。

Abstract: In this paper, Kernel Density Estimation method was used to extract the distribution characteristics of retail business centers in Fuzhou City based on POI (Point of Interest) data of retail industry. The differences in the layout of different retail formats were identified, Getis-Ord Gi* method was applied to identify the hotspots of retail industry in the city. The results show that the retail centers in Fuzhou have formed a multi-center pattern, and the location strategies of different types of business obviously vary. The significant hotspots of high and low (HL) or low and high (LH) agglomeration are expanding, and the overall spatial evolution trend is expanding from west to east and from north to south. This paper has an advanced application level of POI data in urban and rural planning research, so as to improve the rationality of urban commercial facility planning and to promote the distribution of retail location in the city.
