【摘要】：為探討人口、經濟發(fā)展與用水三者之間的聯(lián)系,利用空間重心測度方法,探尋三者的動態(tài)轉移軌跡及時間變化規(guī)律;構建脫鉤分析模型,分析評價用水與經濟發(fā)展和人口增長兩者之間的協(xié)調關系。結果表明,我國水足跡重心的地理位置變化幅度較人口和GDP重心大,水足跡-人口和水足跡-GDP之間的空間協(xié)調性差異均為東西方向大,南北方向小;部分中部省份水足跡-GDP和水足跡-人口之間的脫鉤關系由相對脫鉤轉化為絕對脫鉤,而部分沿海省份則發(fā)生著相反的變化,但總體來說呈未脫鉤狀態(tài)的地區(qū)逐漸減少。
[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.
