摘　　要：基于“总体判断—中心识别—热点探测—因素分析”研究框架,运用多种定量方法研究郑州市中心城区医疗健康资源空间演化模式及其影响因素。结果表明:(1)医疗健康资源空间扩散特征与城市空间发展方向基本一致,主要沿西北—东南分布,空间重心向东北方向转移,其中医院健康资源空间扩散较弱,医药健康资源空间扩散相对稳定,诊疗、理疗健康资源则分别是空间扩散效应最强和扩散速度最快的资源类型。(2)不同类型医疗健康资源的性质决定了其空间演化模式。各类医疗健康资源的空间集聚特征呈现出多中心和网络状的演化趋势,其空间热点则表现出蔓延模式、触角模式和飞地模式3种演化模式。(3)人口、建成环境因素在医疗健康资源格局演化中发挥着根本性和重要性作用,交通、经济因素则起着促进性和基础性作用。此外,重要交互因子空间关联的叠加效应更强化了其对医疗健康资源空间格局的影响。Based on the research idea of“overall judgment-center identification-hot spot detection-factor analysis”,a variety of quantitative analysis methods were used to explore the spatial evolution and influencing factors of medical and health resources in the central urban area of Zhengzhou City.The results show that:(1)The spatial diffusion characteristics of medical and health resources are basically consistent with the development direction of urban space,mainly distributed along the northwest to southeast,and the spatial center of gravity shifts to the northeast.The spatial diffusion of hospital health resources is weak,and the spatial diffusion of medicine health resources is relatively stable.Diagnosis and physical therapy health resources are the strongest spatial diffusion effect and the fastest spatial diffusion speed respectively.(2)The nature of different types of medical and health resources determines their spatial evolution mode.The spatial agglomeration characteristics of various medical and health resources show a multi-center and network evolution trend,and its spatial hotspots show three evolution modes:the spreading mode,the tentacles mode and the enclave mode.(3)Population and built environment factors play a fundamental and important role in the evolution of the pattern of medical and health resources,while traffic and economic factors play a promotive and fundamental role.In addition,the superposition effect of the spatial correlation of important interaction factors further strengthens its impact on the spatial pattern of medical and health resources.
