The objective of this study was to test indicatorsand improve the assessment of groundwater sustainabilityby using a synthetic method. An indicator system ofgroundwater sustainability was constructed under theframework of driver–pressure–state–impact–response, anda method for the assessment of groundwater sustainabilitywas developed by using analytic hierarchy process togetherwith information entropy theory. This method was used tocalculate the weight of each indicator. And then, the sustainabilityscale was determined by the indicator zoningmethods. The assessment results of a case study in HohhotPlain, China, demonstrated that the method greatly reducedthe randomicity and anthropogenic influence on the determinationof weight of indicators; and gave a quantitativeclassification on sustainability scale which produced a rational result on the assessment of groundwater sustainability in Hohhot Plain.
