【摘要】：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。
[Abstract]:In order to explore the relationship among population, economic development and water use, using the method of spatial gravity measurement, the dynamic transfer locus and time change law of the three are explored, and the decoupling analysis model is constructed. The relationship between water use and economic development and population growth is analyzed and evaluated. The results show that the geographical location of water footprint center of China is larger than that of population and GDP. The difference of spatial coordination between water footprint and water footprint-GDP is large in east-west direction and small in north and south direction, and the decoupling relationship between water footprint GDP and water footprint-population in some central provinces has changed from relative decoupling to absolute decoupling. In some coastal provinces, the opposite changes have taken place, but the areas that are not decoupled gradually decrease.
