【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。
[Abstract]:[objective] to analyze the evolution characteristics and coupling relationship between ecological service value and social economic center of gravity in Beijing-Tianjin-Hebei region, and to explore the socio-economic driving factors of ecological service value in Beijing, Tianjin and Hebei areas. It provides a reference for the ecological environment protection in the key area of Beijing, Tianjin and Hebei coordinated development. [methods] using the concept of center of gravity and relevant formulas, using the land use, urban and rural population, From 1990 to 2010, the value of ecological service in Beijing-Tianjin-Hebei region, the center of value added of urban and rural population and the three major industries, the migration direction and the offset distance are calculated, and the consistency formula of overlap and change of gravity shift is constructed. The dynamic evolution and coupling relationship between the ecologic service value and the center of gravity of social and economic factors were studied. [results] from 1990 to 2010, the direction of the shift of the value center of value of the Beijing, Tianjin and Hebei regions was similar to that of adjusting the service, supporting the service and providing the service value. The direction of shift of the center of gravity of cultural service value is different, the direction of shift of center of gravity of value added of rural population and primary industry is similar, while that of urban population, secondary industry value added and third industry value added center of gravity shift has its own characteristics for 20 years. The distance between adjusting service value, total ecological service value and the center of value added of three industries is larger, while the distance between supporting service, supply service, cultural service value and population center of gravity is relatively small. 3) the center of total service value and urban population. The third industry added value, the secondary industry added value center of gravity coupling is higher, and the coupling with the rural population and the first industry added value center is low .4) take the year 2000 as the boundary, the total service value center of gravity is with the second industry added value, the third industry added value, [conclusion] the imbalance of regional development leads to the complexity of the shift of gravity center, and the asynchronous process of industrialization leads to the asynchronism of the shift of gravity center of society and economy. The dislocation of urbanization and industrialization results in the dislocation of the center of value of ecological service, which will be further offset by the coordinated development of Beijing-Tianjin-Hebei, and the center of value of ecological service and the center of social economy in the future.
