基于GIS的城区急救中心空间分布合理性评价研究

摘要

Optimal location and site distribution rationality evaluation of the 120 Emergency Centers are of great significance to the formulation of emergency treatment plan and rational allocation of urban public service facilities. Taking Chengguan District of Lanzhou City as the research area, this paper employs GIS spatial analysis method and the software ARCGIS to carry out buffer analysis and overlay analysis of the main medical sites and the main line of the Chengguan District, and thus to get service coverage areas. The medical emergency service coverage and service level classification map of the Chengguan District of Lanzhou City can be got by grading the coverage areas according to the classification requirement, visually displaying the service level of every area. The results show that medical emergency site distribution of Chengguan District is too concentrated, basically concentrated in urban center, site distribution is not reasonable enough, and there are a lot of overlapping areas and a certain blind zone of service.%120急救中心的优化选址和站点分布合理性评价，对应急处理方案制定和城市公共服务设施合理布局具有重要的现实意义。以兰州市城关区为研究区域，采用GIS空间分析方法和ARCGIS软件对城关区主要医疗站点和交通主干道进行缓冲区分析和叠置分析形成服务覆盖区。根据分级要求对覆盖区进行分级，得到城关区医疗急救服务覆盖及服务等级分等定级图，直观地显示各区域的服务等级。研究结果显示兰州市城关区医疗急救站点分布过于集中，基本集中在市区中心，其站点分布不够合理，存在大量服务重叠区和一定区域的服务盲区。
