Abstract

Investigation into water resources sustainability (WRS) is vital for a regional sustainable development strategy. This paper aimed to quantitatively evaluate the WRS in mainland China using a three-layer indicator system. Three important factors significantly affecting WRS are: water resources quantity (WRQ), water intensity (WI) and water efficiency (WE). Assessment of the three indicators was carried out in 356 cities where each indicator was graded from “very low” to “very high” according to the value magnitude. China was then classified into four zones to differentiate regional variations of the impact of water intensity and efficiency on sustainability. Results showed that 34% of the areas had “medium” to “high” WI indicator values and 58% of the areas had “low” to “very low” WE indicator values. The indicator values of WI were ordered as Zone I > Zone II > Zone III > Zone IV; whereas the WRS were ordered as: Zone I
