摘　　要：依托ArcGIS平台,以神农架松柏镇为例,利用网络分析方法,结合当地道路网络属性,确定合适的通行速度和阻力,构建网络数据集,探究小城镇就医可达性。结合当地居民用地分布特点,计算一定抗阻范围内覆盖的居民地面积与医疗用地可达比,为小城镇偏远地区居民提供抵达全镇唯一的综合医院的耗时最短路径。根据可达性分析结果,综合评价小城镇医疗用地的布局,为医疗用地的合理布局和规划提出相应的建议。Based on the ArcGIS platform, taking the Songbai Town in Shennongjia for example, combined with the local road network attributes, this paper used the network analysis method to determine the appropriate traffic speed and resistance, build the network dataset, and explore the accessibility of small town medical treatment. Considered the distribution characteristics of the local residents, the paper calculated the ratio of the coverage of a certain area within the coverage of the residential area and medical land, which could provide the shortest path for small towns and villages residents with the only general hospital. According to the results of accessibility analysis, this paper evaluated the layout of medical land in small towns synthetically, and put forward the corresponding suggestions for the rational distribution and planning of medical land.
