摘　　要：【目的】分析京津冀地区生态服务价值与社会经济重心演变特征及耦合关系,初步探究地区生态服务价值的社会经济驱动因子,为京津冀协同发展的重点领域生态环境保护提供参考。【方法】运用重心概念及相关公式,采用分县区的土地利用、城乡人口、三大产业数据计算1990—2010年京津冀地区生态服务价值、城乡人口和三大产业增加值重心及其偏移方向和偏移距离;构建重心偏移的重叠性和变动的一致性公式,研究地区生态服务价值和社会经济因子重心的动态演化及耦合关系。【结果】1)1990—2010年,京津冀地区调节服务、支持服务、供给服务价值重心偏移的方向类似,文化服务价值重心偏移方向有所不同;乡村人口和第一产业增加值重心偏移的方向类似,而城镇人口、第二产业增加值、第三产业增加值重心偏移方向各具特点。2)20年来,调节服务价值、总生态服务价值和三大产业增加值重心偏移的距离较大,而支持服务、供给服务、文化服务价值和人口重心偏移的距离相对较小。3)总服务价值重心与城镇人口、第三产业增加值、第二产业增加值重心的耦合性较高,与乡村人口和第一产业增加值重心的耦合性较低。4)以2000年为界,总服务价值重心与第二产业增加值、第三产业增加值、城镇人口重心变动的一致性有所转变。【结论】地区发展不平衡造就重心偏移的复杂性,工业化进程的异步导致社会经济重心偏移的异步,城市化与工业化的错位致使生态服务价值重心偏移错位;受京津冀协同发展的影响,未来地区生态服务价值重心和社会经济重心将进一步偏移。【Objective】The aim that analysis of dynamic evolution and coupling relationship between the gravity center of ecological services value and socio-economic factors in Beijing-Tianjin-Hebei region,is to explore socio-economic driving factors of the regional ecological service value, so as to provide a certain basis of Beijing-Tianjin-Hebei collaborative development in the key areas of ecological environmental protection. 【Method 】Using the concept of the gravity center and correlation formula,applying various counties in land use,urban and rural population,the three major industries data of Beijing-Tianjin-Hebei region to calculate the gravity center of ecological services value,urban and rural population,the three major industries added value and their shift direction and offset distance from 1990 to 2010.Constructing the overlap of the gravity center and change consistency formula to study their dynamic evolution and coupling relationship between the gravity center of ecological services value and socio-economic factors in Beijing-Tianjin-Hebei region.【Result】1） The shift direction of the gravity center of regulating services,supporting services and providing services value was similar from 1990 to 2010,the shift direction of the gravity center of cultural service value was different. The shift direction of the gravity center of rural population and primary industry added value was similar,whilethe shift direction of the gravity center of urban population,secondary industry added value,and tertiary industry added value had their own characteristics. 2） The offset distance of the gravity center of regulating services,the total value of ecological services and the three industrial added value was far for more than 20 years,while the offset distance of the gravity center of supporting services,providing services and cultural services value was close relatively. 3） The coupling of the gravity center between total ecological services value and urban population,tertiary industry added value,secondary
