西北干旱内陆河流域城镇化与水资源环境系统耦合机理

Analysis of the Coupling Mechanism Between the Urbanization of the Arid Inland River Basins in Northwestern China and the Water Resource Environmental System

水资源是西北干旱内陆河流域经济社会可持续发展最基本的约束条件,城镇化是实现可持续发展的重要环节,水资源的高效合理利用和城镇化的健康有序发展均是影响该区域可持续发展的关键因素。剖析了城镇化与水资源环境系统之间存在的耦合机理以及不同发展阶段的耦合作用强度,阐述了内陆河流域水资源利用时空转移下的城镇发展演变机理。

The lack of water resources in the arid inland river basins in northwestern China restricts the economic and social development.Urbanization is an important part of achieving sustainable development.The efficient and reasonable utilization of water resources and the healthy and orderly development of urbanization are,therefore,the key factors affecting sustainable development in this region.This paper has analyzed the coupling mechanism exiting between urbanization and the water resource environmental system,the coupling strength at different developmental stages,and the evolution mechanism of the basins＇ urbanization as time advances and space changes.
