关于国内外灰水足迹的研究综述

A REVIEW OF RESEARCHES ON THE GRAY WATER FOOTPRINT

随着社会经济的快速发展,水资源面临着数量与质量的双重挑战,水质挑战尤为突出。因此,做好水质评价具有重要意义。灰水足迹作为一种新的水质评价方法起步较晚,其概念的提出为定量评价水质对水量的影响提供了新的思路。从灰水足迹研究时空尺度、研究对象、计算方法等多个角度介绍灰水足迹国内外研究进展,总结我国灰水足迹研究的不足,并结合我国水资源实际情况,对灰水足迹的研究提出合理性建议。

With the rapid development of social economy,water resources face with the dual challenges of quantity and quality,especially water quality challenge. Therefore,good water quality evaluation is of great significance. As a new method of water quality evaluation,the gray water footprint starts late,and its concept provides a new idea for quantitative evaluation of water quality. This paper introduces the research progress of gray water footprint in China and abroad from the perspective of spatial and temporal scale,research object,calculation method,and summarizes the shortcomings of research on gray water footprint,and puts forward some reasonable suggestions on the research of gray water footprint by combined with the actual situation of China＇s water resources.
