对城市常住人口与公共服务资源进行合理配置,是城市发展中一项重要任务。该文以广州市为研究区域,基于DMSP/OLS夜间灯光数据,对全市常住人口进行空间化处理;同时利用Huff改进模型,计算格网单元公共医疗资源分配份额;最后以这两类指标为变量,计算区域公共医疗服务水平匹配度。研究结果表明:1)人口空间化结果能弥补传统人口统计数据分辨率低的问题,能更细致地刻画广州区域内部人口分布特征;2)格网单元的公共医疗资源分配份额与广州市全域公共医疗设施核密度两者之间具有较高的耦合性,形成"一主片区,多核心"的空间分布格局;3)广州市公共医疗服务水平匹配度在局部空间分布具有明显的圈层现象,指数高值区域主体部分与广州市中心城区的范围基本吻合,以此为中心向外扩散,匹配度逐渐降低。
Abstract：Reasonable allocation of urban permanent population and public service resources is an important task in urban development planning.Taking Guangzhou as the study area,based on the DMSP/OLS nighttime light data,this paper carried out the spatial treatment of Guangzhou′s permanent population.At the same time,the improved Huff model was used to calculate the allocation of public medical resources in each grid unit.Finally,these two indicators were used as variables to calculate the matching degree of public medical service level.The results show that:1) The result of population spatialization can make up for the low resolution of traditional population statistics,and display the characteristics of population distribution in Guangzhou.2) There is a high degree of coupling between the allocation of public medical resources of grid units and the nuclear density of public medical facilities in Guangzhou.And the spatial distribution pattern of "one main area,multi core" is formed.3) The matching degree of public medical service level in Guangzhou has obvious circle phenomenon in the distribution of local space.The main part of the high index value area is basically consistent with the scope of the central district of Guangzhou.With the outward diffusion,the matching degree is gradually reduced.
