摘要
基于可达性相关理论,以GIS网络和空间分析技术为基础,运用改进的潜能模型和两步移动搜寻法,对大连市各社区人口和医院进行叠加分析,将标准化的可达性数值进行插值处理,使之空间可视化,探究了大连市中山区、西岗区、沙河口区人口和二级以上医院空间分布现状,并对大连市医疗可达性进行了评价。结果显示:大连市医疗设施北部集中,总体分布不均。西岗区医疗可达性总体状况良好;中山区人口分布密集区,医疗可达性较好;沙河口区可达性较差,亟待提高。两步移动搜索法能更有效反应区域医疗可达性的空间分异。
Based on the theory of accessibility and GIS network analysis this study conduct a comprehensive inquiry of hospitals、community distribution and transportation networks in the south main city of Dalian. Using improved potential model and two-step floating catchment area method to get health care spatial accessibility value of every community in the south main city and make the value spatial visualization by analysis on spatial interpolation. The results showed that： health care facilities in Dalian concentrate in the north,overall distributed is uneven. Total spatial accessibility of health care in Xigang is favorable; accessibility of Zhongshan high populated areas fit better; Shahekou accessibility is poor,need to be improved. The two-step floating catchment area method can be more effective reaction regional medical accessibility spatial differentiation.
