西北干旱区内陆盆地地下水资源及其勘查方向

水是制约西北干旱区社会经济发展的瓶颈因素。从分析西北内陆盆地水文地质条件入手，利用国土资源大调查项目的最新资料，系统地评价各盆地地下水的补给资源，允许开采资源，总水资源和可利用水资源的数量及地下水资源的开发利用潜力。同时，阐述了加强地下水资源管理的必要性，并以含水层系统理论为指导思想，分盆地论述了未来地下水资源的勘查方向。研究得出，西北干旱区内陆盆地地下水资源丰富，开发利用程度平均只有23．9％，尚具有较大的开采潜力。未来地下水的勘查方向是深层水和沙漠水。

Inland Basins in Arid Region of Northwestern China:Groundwater Resources and Direction of Survey

Starting with an analysis of hydrogeology conditions of the inland basins in northwest region of China and utilizing the latest information from the survey of land resources, this paper evaluates systematically the supply resources of underground water in each basin, permissible exploitation resources, total resources of water and exploitation potential of usable water and groundwater resources. Guided by the theory of water-bearing stratum system, this paper also discusses the directions of prospecting groundwater resources in each of the basins,with the conclusion that the inland basins in northwest region is rich in groundwater resources and that the future survey is to be focused on deep-layer water and desert water.
