摘　　要：对长沙市某医院2016年1~3月份的就诊患者地址数据进行地理编码及可视化处理,采用欧式距离、曼哈顿距离、道路距离、最短行驶时间方法分析不同距离模式下患者到该医院就医的空间分布状况;另外,结合分位数评价指标定量分析3种距离模式下服务半径和服务面积的异同以及影响该医院服务范围的因素,分析得到该医院的服务范围呈中心辐射状,主要服务半径较小(约8 km),服务辐射范围在150 km^2以内,且受距离成本、时间成本和地形要素影响明显。In this paper, we realized geocoding and visualization with patients address data of a hospital in Changsha of January to March in 2016, and obtained the different results between patients address to the hospital using Euclidean distance, Manhattan dis-tance ,road distance and the shortest driving time methods. Moreover, we analyzed the similarities and differences in service radius and area quantitatively under three distance methods and the impact factors of the hospital s service area combined quantile evaluation. The results shown that the hospital services area mainly presented a trend of radiating outward from the center , significantly affected by distance and time costs. Its main service radius is small, about 8 km, the service area is about 150 km2, and the distance from the cost, time cost and terrain factors significantly.
