A comprehensive evaluation of water footprint,water resources utility and urban and rural residents'virtual water consumption diversity index in Wuwei City from 1995to 2009was made based on the calculation of water footprint by introducing the concept of water footprint.A dynamic analysis of water resources utility was made according to the co-integration analysis model in dynamic econometrics.Results showed that water resources utility in Wuwei City was poor and it had a stable relationship with water resources utility,water footprint and urban and rural consumption structure.Therefore,some effective measures of water resource management must be taken as soon as possible.However,as the interaction between water use efficiency and other indexes is dynamical,people should consider the influences of water footprint and urban and rural consumption structure variables while taking the measures to improve the efficiency of water resources.
