摘　　要：在分析城市化与水资源交互胁迫关系的基础上,借助于系统科学理论建立了城市化与水资源协调发展的动态耦合模型,对甘肃河西走廊城市化与水资源协调发展的动态耦合规律进行了初步探讨。结果表明:自1985年以来,河西走廊城市化水平在曲折发展中呈现出明显升高的变化趋势;水资源压力不断增大,并呈现出对城市化具有一定影响的特征。目前河西走廊正处于城市化与水资源的协调发展阶段,然而随着城市化的推进,水资源压力不断增长,二者的耦合状态有不断减弱的趋势。这也进一步说明,在干旱区,水资源压力随城市化的推进呈现出一定的变化规律,城市化的发展往往是需要一定的水资源压力为代价的,然而随着城市化的发展,城市化与水资源的关系不断得以磨合,最终将朝着协调共生的方向发展。Based on analysing the interactive coercing relation between urbanization and water resources, a dynamic coupling model for the harmonious development between urbanization and water resources was set up with system theory to study dynamic harmonious law of urbanization and water resource in Hexi Corridor, Gansu Province, China. The results showed that the urbanization level in Hexi Corridor and the water resource stress had increased evidently and gradually since 1985. The response of water resources to urbanization had appeared but not been evident. At present, the harmonious development system of urbanization and water resource in Hexi Corridor was in its developmental phrase. However, the water resources stress increased quickly with the advancement of urbanization. The coupling state of urbanization and water resources showed weakening trend also. From the temporal change of the coupling degree, it could be concluded that urbanization sometimes needed some cost of the water resource stress in its initial stages, but as the urbanization continued, the coupling state of urbanization and water resources would meliorate and advance along the harmonious and symbiotic direction. So, it is crucial to recognize the dynamic coupling law between urbanization and water resources, and adopt the proper mode to realize the sustainable development of the urbanization in Hexi Corridor.
