摘　　要：选取32项与敦煌市城市发展和水资源利用潜力紧密相关的评价指标,分别构建城市发展和水资源利用潜力综合评价模型,在此基础上再构建两系统间协调度模型,分析城市发展与水资源利用潜力的变化及两者的协调关系,得出如下结论:(1)敦煌市城市发展综合水平逐年上升,经济快速发展是促进敦煌城市综合发展的主要动力。2000—2006年城市人口增长速度较快,城市社会发展和城市空间扩张速度较慢。2007—2012年城市社会发展速度变快,城市人口增长和城市空间扩张对城市综合发展影响变小;(2)敦煌市水资源利用潜力呈逐年下降趋势,水资源本底条件对水资源利用潜力约束较强,提高水资源利用效率和加强水资源管理能力是提升水资源利用潜力的重要举措和有效途径;(3)敦煌市城市发展与水资源利用潜力协调度总体不高,两系统间矛盾日益突出。In this paper, 32 indexes had been selected to set up evaluation models. Comprehensive evaluation models were built to analyze the change of urban development and water resources utilization potential. The model of coordination degree was constructed to evaluate the coordination relationship between the urban development and water resources utilization potential. The result showed that. （1） comprehensive urban development of Dunhuang City continued to improve from 2000 to 2012, the rapid increase of GDP was the main force of comprehensive urban development, from 2000 to 2006, the increase of urban population and economic development were faster than urban social progress and urban spatial expansion, from 2007 to 2012 ,urban social progress had significant increase of comprehensive urban development whereas the urban population and urban space expansion had relatively small impact; （2） comprehensive index of water resources utilization potential index declined from 2000 to 2012, under the constraints of natural background of water resources, the improvement of utilization efficiency and management of water resources were the significant measures and ways enhancing water resources potential; （3） generally, the coordination degree between urban development and water resources utilization potential was low and the conflict between the two systems had been intensified.
