摘要:

引入人口规模因子和医疗设施等级规模影响系数改进潜能模型,基于GIS空间分析技术,以上海杨浦区为例对其医疗设施空间可达性进行研究。结果表明:杨浦区医疗设施空间可达性分布不均,大桥街道、定海路街道及殷行街道部分区域医疗设施空间可达性较高;中部区域一些街道存在同等级医院位置密集、医疗资源相对集中的情况;杨浦区三级医院的居民就医空间可达性整体优于二级、一级医院。改进的潜能模型综合考虑了居民点人口数量、医疗设施与居民点之间的出行阻抗、以及医疗设施的等级规模对居民就医选择的影响,能更合理地评价医疗设施的可达性。研究结果可为城市医疗设施科学规划与决策提供依据。

Abstract:

Medical services are the basic requirement of the public and are closely related to public health. The rationality of the layout and spatial accessibility of medical facilities are closely related to the right of the public to healthcare. Spatial accessibility of medical facilities represents the convenience for residents to obtain medical services. Using GIS and an improved potential model that introduces population scale factor and medical facility grade influence coefficient to traditional potential model, the spatial accessibility of urban medical facilities in Yangpu District of Shanghai was studied. By applying a spatial interpolation method, accessibility of medical facilities of Yangpu District in 2016 was obtained. Moreover, hotspot analysis was used for the cluster analysis of spatial accessibility. The results indicate that the spatial accessibility of urban medical facilities in different community of Yangpu District varies. The spatial accessibility in the central area of Yangpu District is higher than that of other areas. Spatial accessibility is relatively high in Daqiao subdistrict, Dinghai Road subdistrict, and some areas of Yinxing subdistrict. Hospitals of the same grade in the subdistricts of the central area are so closely located that medical resources are of high concentration in these areas. Overall, spatial accessibility of tertiary hospitals is better than secondary and primary hospitals in Yangpu. The improved potential model can evaluate the spatial accessibility of urban medical facilities reasonably by integrating population in demands, travel impedance between residential areas and medical facilities, and the influence of medical facility grade on residents' choice of medical services. By using GIS, the difference of spatial accessibility of urban medical facilities can be visualized. Furthermore, areas with insufficient medical resources can be defined. The results can not only enrich public facility spatial planning theory, but also provide references for the decision making of relevant government departments.
