摘要
以湖北省仙桃市为研究区域,运用改进区位配置模型,通过调整设施数量和规模实验,研究农村就医空间优化布局。首先对比分析传统区位配置模型(LA模型),引入等级规模偏好系数,构建改进区位配置模型。然后基于Arc GIS10.2 Geoprocessing框架,整合GIS网络分析,运用程序设计语言Python和线性规划建模工具Pu LP实现模型构建,运用线性规划软件Cplex实现模型求解,运用Arc GIS10.2进行地理空间可视化表达。最后通过调整设施数量和规模对比实验发现:医疗机构布局调整后更加合理,居民就医效率明显提高,居民获得医疗服务时间成本减少,且15 min内满足更多医疗需求,验证了改进区位配置模型在农村就医空间优化布局的实用性。
With the acceleration of urbanization in China, a large number of rural people have shifted towards into urban area. With the number of local people decreasing in recent years, the result has influenced the problem on how to spatially arrange public basic service facilities in rural area. The centralized layout, expandedsize, service quality improved for the public services is the common phenomenon in rural area by merger of village and by abolishing village government. However, with the limitation on the resources, the expanding for each facility lead to the number of facilities decreased, serving radius of facilities increased, and their accessi- bility lowered. The study on that ＂how-to＂ in a scientific and reasonable way provides an effective way for solving the contradiction between quality and accessibility. The spatial arrangement of public health facilities is the key component of the study on the equalization of public services. Therefore the study on their spatial optimization has been paid more and more attention in research fields, such as human geography, medicine, public health and sociology. Taking Xiantao City in Hubei Province as a survey region, we analyzed the spatial optimization of medical services in rural area. The attributes from economy and the natural geography shows homogeneity in our survey region with the typicality in the Jianghan Plain, which is easy to further our research and construct model. Firstly, according to traditional location-allocation model, based on medical demand preference question- naire from rural residents and rank-size index evaluation system, the medical behavior preference coefficient from residents, namely the rank-size preference coefficient is built, which is introduced to traditional location configuration model to establish the improved location-allocation model. Secondly, with the integration of GIS network analysis, linear programming modeling tools PuLP and linear programming software Cplex, this arti- cle optimizes geographic visualization layout
