Study on the Spatial Distribution Pattern and Clustering Characteristics of Retail Pharmacies in Guangzhou

本文基于POI大数据和GIS空间分析技术,研究广州市零售药店的空间分布格局和集聚特征,并结合居民小区的空间分布特点和各街镇的人口密度情况,探究广州市零售药店空间分布的影响因素,为广州市零售药店的空间配置和优化布局提供科学参考。研究发现,广州市零售药店的空间分布不均衡,呈现出“单核、三带、多点”的分布格局,且具有中心聚集、外围分散的特点;零售药店表现出沿居民小区的分布趋势,且主趋势与各街镇人口密度特征吻合;在街道(镇)尺度上广州市零售药店的数量呈现空间聚类模式。

This paper studies the spatial distribution pattern and clustering characteristics of retail pharmacies in Guangzhou based on POI data and GIS spatial analysis technology,and investigates the factors influencing the spatial distribution of retail pharmacies in Guangzhou by taking into account the spatial distribution characteristics of residential neighborhoods and the population density of each street(town)to provide scientific reference for the spatial allocation and optimal layout of retail pharmacies in Guangzhou.The results show that:the spatial distribution of retail pharmacies in Guangzhou is uneven,showing a distribution pattern of“single core,three strips and multiple points”,with a characteristic clustering at the center with peripheral dispersion;the distribution of retail pharmacies shows a trend of distribution along residential neighborhoods,and the main trend matches the population density of each street(town);the number of retail pharmacies in Guangzhou on street(town)scales shows a spatial clustering pattern.
