【摘要】：论文在对中国大陆31个省市1998—2013年各类来源的灰水足迹进行测算的基础上,选取人口、GDP两个指标,应用基尼系数对中国1998—2013年灰水足迹的空间、结构均衡性情况进行了研究。结果显示:1)在区域均衡性方面,经济灰水足迹均衡性较差,东部与西部地区分别在经济灰水足迹和人口灰水足迹中的均衡性较低;2)在结构均衡性方面,经济灰水足迹均衡性已达到"差距偏大"范围,其中农业和工业的均衡性较差,生活经济灰水足迹均衡性近年来降幅明显;3)从边际效应来看,可以通过减少中、西部重污染地区灰水足迹及各省市农业灰水足迹的方式提升整体均衡性,有效促进中国水环境公平性的提升。最后,针对中国灰水足迹均衡性的具体问题,提出了减少中国灰水足迹、提升水环境公平性的相关建议。
[Abstract]:On the basis of measuring the ash water footprint of 31 provinces and cities in mainland China from 1998 to 2013, the paper selects two indexes of population GDP, and applies Gini coefficient to the space of China's grey water footprint from 1998 to 2013. The structural equilibrium is studied. The results show that the balance of economic grey water footprint is poor in the area of regional equilibrium, and the balance of economic grey water footprint and population grey water footprint in the eastern and western regions are lower than that in the eastern and western regions, respectively. 2) the structural equilibrium of the economic grey water footprint and the population grey water footprint is lower in the eastern and western regions, respectively. The balance of economic ash water footprint has reached the range of "wide gap", in which agriculture and industry have a poor equilibrium, and the balance of life economic ash water footprint has decreased significantly in recent years. The way of grey water footprint and agricultural ash water footprint in the heavily polluted areas of western China can promote the balance of water environment in China effectively and promote the equity of water environment in China. Finally, aiming at the specific problem of the balance of China's ash water footprint, the paper puts forward some suggestions to reduce China's ash water footprint and improve the equity of water environment.
