摘　　要：与其他地区相比,我国西北内陆盆地城镇化对水资源尤其是地下水资源的影响更大。以河西走廊石羊河流域中游城市武威市为例,研究了武威市城镇化进程与中游和下游地下水资源变化的关系。研究表明,在西北内陆盆地,中游城市城镇化发展对下游地下水资源量的影响远大于对中游地下水资源的影响,城市的用水方式对下游地区的水资源影响也很大。在内陆盆地城镇化进程中,应当注重水资源的统筹分配,实现中游城镇化与下游水资源及生态环境问题的协调发展。Compared with other regions,urbanization of the inland river basins in northwest China has more influence on water resources,especially on groundwater resources. In the case of Wuwei City in the middle reaches of Shiyang River Basin in Hexi Corridor,the relation between urbanization and variation of groundwater resources in the mid- lower reaches is studied. The results show that in the inland river basins in northwest China,the urbanization of midstream area has a larger impact on the downstream groundwater resources than on the midstream groundwater resources; the urban water utilization mode also has a serious impact on the groundwater resources. Therefore,in the process of urbanization in the inland basins,the integrated utilization and allocation of water resources should be focused to achieve a harmonious development among urbanization of midstream area, downstream water resources and ecological environment.
