摘    要:引入水资源足迹的概念,以水资源足迹的计算为基础,对武威市1995-2009年水资源足迹、水资源利用效率以及城乡居民虚拟水消费多样性指数等指标进行了综合评价.运用动态计量经济学的协整分析模型对水资源利用效率与其相关指标进行了动态均衡分析.结果表明,武威市水资源利用效率较低,与水资源足迹、城乡消费结构之间存在长期稳定的关系.采取相应的水资源管理措施已刻不容缓.水资源利用效率与其他指标之间是一个相互影响的动态系统,因此,在实施提高水资源利用效率措施的同时,必须考虑其水资源足迹和城乡居民消费结构变量的影响.

关 键 词:水资源足迹  水资源利用效率  协整分析  动态均衡分析

Abstract: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.
Keywords:water footprint  water resources utility  co-integration analysis  dynamic equilibrium relationship
