为探究石家庄市主城区各类医疗资源空间分布格局及其影响因素，将主城区医疗资源分为3个大类5个子类，基于各类医疗资源兴趣点（POI）数据进行了核密度分析、平均最邻近分析、标准椭圆差分析和地理探测器分析.结果表明：主城区各类医疗资源在空间上分布不均匀，呈现出明显的“中心—外围”分布特征，各类医疗资源主要集中在二环内，东部及北部较为匮乏；主城区医疗资源呈“西北—东南”方向分布，与城市格局及发展方向较为吻合，其中三级公立医院方向性分布特征最为显著，二级公立医院方向性分布不明显，私人诊所在主城区覆盖范围最广，向心性较差；除二级公立医院外，其他各类医疗资源在空间上呈显著性聚集分布；主城区各类医疗资源空间分布受到人口、经济、交通、区位等多方面因素影响，其中居住区密度对其分布影响最大，道路密度影响最小.

In order to explore the spatial distribution pattern and influencing factors of various medical resources in the main urban area of Shijiazhuang City, medical resources have been divided into three categories and five subcategories. Based on the point of interest(POI) data of various medical resources, nuclear density analysis,average nearest neighbor analysis, standard elliptic difference analysis and geographic detector analysis have been carried out. The results show that the spatial distribution of various medical resources in the main urban area is uneven, showing obvious "center-periphery" distribution characteristics, and all kinds of medical resources are mainly concentrated in the second ring road, and the western and northern parts are scarce. The distribution of medical resources in the main urban area is in the direction of "northwest to southeast", which is more consistent with the urban pattern and development direction. Among them, the directional distribution characteristics of tertiary public hospitals are the most significant, while that of secondary public hospitals is not obvious, and private clinics have the widest coverage in the main urban area with poor centrality. Except for secondary public hospitals, other types of medical resources show significant spatial aggregation and distribution. The spatial distribution of various medical resources in the main urban area is affected by population, economy, traffic, location and other factors,among which the density of residential areas has the greatest impact on its distribution, while the density of roads has the least impact.
