摘要
黄河流域最大的矛盾是水资源短缺,如何科学揭示大尺度缺水型流域城市群水资源利用与经济发展之间的脱钩关系,是黄河生态保护和高质量发展的重大战略管理需求,也是水科学与经济学交叉学科的研究难点.本文发展了基于三维水资源生态足迹和Tapio弹性指数的耦合脱钩模型方法,辨识黄河流域城市群2010-2020年水资源生态足迹时空变化格局及其水资源可持续利用水平,从广度和深度多个维度定量揭示了黄河流域城市群水资源利用与经济发展的脱钩状态.结果表明:(1)2010-2020年黄河流域兰西城市群具有最大的水资源生态足迹广度和最小的水资源生态足迹深度,平均值分别为570.73×10^(4)hm^(2)和1.25;宁夏沿黄城市群则具有最小的水资源生态足迹广度和最大的水资源生态足迹深度,平均值分别为2.01×10^(4)hm^(2)和567.05.(2)黄河流域水资源可持续利用水平最强的是山东半岛城市群,相对较低的是宁夏沿黄城市群.(3)水资源生态足迹广度与GDP发生强脱钩和扩张性负脱钩的比例分别为49.68%和36.13%,水资源生态足迹深度与GDP发生强脱钩和扩张性负脱钩的比例分别为41.29%和34.03%,二者均未达到最佳脱钩状态.研究显示,为提升黄河流域水资源可持续利用水平,水资源生态足迹广度与GDP弱脱钩、水资源生态足迹深度与GDP强脱钩是最佳状态.
The biggest problem in the Yellow River Basin is the shortage of water resources.Scientifically revealing the decoupling relationship between water resources utilization and economic development in water-scarce basin urban agglomerations is a major strategic management requirement for ecological protection and high-quality development of the Yellow River,and is also a difficulty in the interdisciplinary research on water science and economics.This paper developed a coupled decoupling model method based on 3D water resources ecological footprint and Tapio elastic index to identify the spatial-temporal change pattern of water resources ecological footprint and its sustainable water resources utilization level in the Yellow River Basin urban agglomerations from 2010 to 2020,and quantitatively revealed the decoupling state of water resources utilization and economic development in the Yellow River Basin urban agglomerations from multiple dimensions of size and depth.The results show that:(1)During 2010-2020,the Lanxi urban agglomeration in the Yellow River Basin has the largest water resources ecological footprint and smallest water resources ecological footprint depth,with average values of 570.73×10^(4)hm^(2)and 1.25,respectively.The Ningxia along the Yellow River urban agglomeration has the smallest water 42 resources ecological footprint size and largest water resources ecological footprint depth.The average values were 2.01×10 hm and 567.05,respectively.(2)The highest level of sustainable water resources utilization in the Yellow River Basin is in the Shandong Peninsula urban agglomeration,and the lowest is in Ningxia along the Yellow River urban agglomeration.(3)The proportions of strong decoupling and expansive negative decoupling between the water resources ecological footprint size and GDP were 49.68%and 36.13%,respectively.The proportions of strong decoupling and expansive negative decoupling between the water resources ecological footprint depth and GDP were 41.29%and 34.03%,respectively,both of which fa
