摘　　要：以长江经济带2010年的131个地级单元为研究对象,采用空间自相关、逐步回归、地理加权回归方法分析了长江经济带人口健康水平的空间格局及影响因素。结果表明:①长江经济带人口健康水平呈现下游高、中游次之、上游最低的东西梯度分异格局,健康水平的区域差异显著,健康公平性有待提高。②长江经济带人口健康水平受自然、经济社会因素综合影响,千人卫生机构数、平均受教育年限、人均GDP对人口健康水平有显著正向影响,海拔、气温对人口健康水平有显著负向影响。③自然、经济社会因素对人口健康水平的影响具有显著的空间异质性,人均GDP对人口健康水平的正向影响呈现东强西弱的梯度分异,千人卫生机构数、平均受教育年限对人口健康水平的正向影响则呈现西强东弱的梯度分异,海拔、气温对人口健康水平的负向影响呈现东强西弱的梯度分异。This paper takes 131 prefecture units of the Yangtze River Economic Zone in 2010 as the research object,and uses the methods of spatial autocorrelation, stepwise regression and geographic weighted regression to analyze the spatial pattern and influencing factors of population health level in the Yangtze River Economic Zone. The results showed that:1) The population health level in the Yangtze River Economic Zone presents a pattern of east-west gradient differentiation,which is higher in the lower reaches, lower in the middle reaches and lowest in the upper reaches. The regional difference of population health level is significant,and the health equity needs to be improved. 2) The population health level in the Yangtze River Economic Zone is affected by natural, economic and social factors. Concretely speaking, the health institutions per thousand people, average years of education and GDP per capita have significant positive effects on the population health level, the order of impact intensity from large to small is the health institutions per thousand people,average years of education, per capita GDP, while the altitude and temperature have significant negative effects on the population health level,the order of influence intensity from large to small is altitude and temperature. 3) The influence of natural, economic and social factors on population health level has significant spatial heterogeneity. Specifically, the positive impact of GDP per capita on population health level shows a gradient differentiation of strong in the east and weak in the west. The positive impact of health institutions per thousand people and average years of education shows a gradient differentiation of strong in the west and weak in the east. The negative impact of altitude and temperature on population health level also shows a gradient differentiation of strong in the east and weak in the west.
