摘要 目的了解中国各省份居民健康状况空间分布情况,为促进居民健康状况均衡发展提供科学依据。方法基于SPSS 18.0软件中的主成分分析和ArcGIS 10.2软件中的空间自相关分析,本文研究了2007—2017年中国居民健康状况不均衡的时空变化及区域差异。结果 2007年、2012年、2017年全国平均居民健康状况指数分别为1.311、1.255、1.589,东部地区各省份3年的居民健康指数均大于1.6,表明东部地区居民健康状况优于全国平均水平;西部地区各省份3年的居民健康指数均小于1.2,表明西部地区居民健康状况低于全国平均水平;2007年、2012年、2017年居民健康指数的全局Moran’sI值分别为0.152、0.137、0.142,说明中国居民健康状况总体具有正的空间相关性。结论 2007—2017年,中国居民健康状况不均衡现象存在着区域聚集性,具有明显聚集性的地区主要在我国西部、中部和东部地区,并且始终维持着"东部—中部—西部"阶梯式逐渐减少的趋势。 Objective To understand the spatial distribution of Chinese health status in different provinces,and to provide scientific basis for promoting the balanced health status of residents.Methods Based on the principal component analysis and spatial auto-correlation analysis in ArcGIS10.2 software,the spatial and temporal changes and regional differences in the unbalanced health status of Chinese residents were discussed since 2007.Results In 2007,2012 and 2017,the national average resident health index were 1.311,1.255 and 1.589,respectively.In the three years,the health indexes in the eastern region were all greater than 1.6,indicating that the health status of residents in the eastern region were better than the national average level.The three-year resident health index in western China was less than 1.2,indicating that the health status of residents in western China were lower than the national average level.In 2007,2012 and 2017,the global Moran of the resident health indexes were 0.152,0.137,0.142,respectively,indicating that the overall health status of Chinese residents had a positive spatial correlation.Conclusion From 2007 to 2017,the unbalanced health status of Chinese residents was characterized by regional aggregation.The regions with obvious aggregation were mainly concentrated in the western,central and eastern regions of China,and the trend of " east-central-west" gradual decrease is maintained.
