基于决策树模型的医疗设施可达性影响因素分析--以苏州市为例

Analysis of Influencing Factors of Medical Facility Accessibility Based on Decision Tree Model:A Case Study of Suzhou City

精准衡量城市医疗设施的空间配置情况、合理规划医疗公共空间,是实现城市稳定健康发展的重要保障。以江苏省苏州市为例,运用两步移动搜索法,以街道为最小单元测算医疗设施的空间可达性,并基于决策树模型探讨影响苏州市医疗设施可达性空间格局的主要因素。分析结果表明:苏州市医疗设施可达性自中心城区向郊区逐渐递减;且人口密度对医疗设施可达性影响显著,住宅区密度、容积率对医疗设施可达性影响较显著,人均GDP、路网密度和老龄化程度对医疗设施可达性作用较弱。据此提出改善苏州市医疗设施分布均衡性和公平性的政策建议,以期为其他城市医疗设施建设提供借鉴。

Accurately measuring the spatial configuration of urban medical facilities and rationally planning medical public space are important guarantees for the realization of stable and healthy urban development.Taking Suzhou City as an example,the study uses the two-step mobile search method to measure the spatial accessibility of medical facilities with streets as the smallest unit,and discusses the main factors affecting the spatial pattern of medical facilities accessibility in Suzhou City based on a decision tree model.The research shows that the accessibility of medical facilities in Suzhou gradually decreases from the central urban area to the suburbs.The population density has a significant impact on the accessibility of medical facilities,and the density of residential areas and plot ratio have a significant impact on the accessibility of medical facilities.The network density and the degree of aging have a weak effect on the accessibility of medical facilities.Based on this,the study puts forward policy recommendations to improve the distribution balance and fairness of medical facilities in Suzhou,and provides references for the construction of medical facilities in other cities.
