以长江中下游地区为例,采用空间自相关方法考察各县级单元人口健康水平的空间集疏格局,利用变异函数方法分析健康水平空间分异随距离变化的总体特征与方向性规律,引入地理探测器方法考察典型自然、人文因子对健康空间分异格局形成的单一影响与交互作用。研究表明:1)2010年案例区人口健康水平高于全国均值,各县级单元人均预期寿命存在一定差异,总体上呈现“东高、西低”、“下游高、中游低”的空间格局,高值集聚区多分布在苏南、浙西、上海等地,低值区相对分散,多集中在鄂西、湘西、赣东南与皖北、苏北等地;2)健康水平的空间自相关最大距离为555km,空间总变异主要来源于结构性因素且具有明显的方...

In this paper,the spatial autocorrelation method was used to study the spatial distribution pattern of the population health level at county-scale in the middle-lower reaches of the Yangtze River.The variation function was employed to analyze the general characteristics and directionality of the health spatial differences change with distance.Furthermore,the geographic detector method was used to study the single and interaction impacts of the typical natural and human factors.The results showed that:1)In 2010,the population health level in the case area was higher than that of the national av...
