为探讨人口、经济发展与用水三者之间的联系,利用空间重心测度方法,探寻三者的动态转移轨迹及时间变化规律;构建脱钩分析模型,分析评价用水与经济发展和人口增长两者之间的协调关系。结果表明,我国水足迹重心的地理位置变化幅度较人口和GDP重心大,水足迹-人口和水足迹-GDP之间的空间协调性差异均为东西方向大,南北方向小;部分中部省份水足迹-GDP和水足迹-人口之间的脱钩关系由相对脱钩转化为绝对脱钩,而部分沿海省份则发生着相反的变化,但总体来说呈未脱钩状态的地区逐渐减少。
In order to explore the relationship between population, economic development and water use, the spatial gravity measurement method is used to explore the dynamic transfer trajectory and time variation of the three; to construct a decoupling analysis model to analyze the relationship between water consumption and economic growth and population growth Coordination between the relations. The results show that the geographic location of water footprint in our country is larger than that of population and GDP. The difference in spatial coordination between water footprint and population and water footprint is large in east-west direction and small in north-south direction. -GDP and Water Footprint-The decoupling of population from decoupling to absolute decoupling, while in some coastal provinces, the opposite happens, but the overall decoupling is declining.
