摘　　要： 通过对我国西北内陆区水循环分析,剖析了河西内陆河流域的水循环特点,即在山区形成水资源、在平原散失水资源和在人工绿洲区产生二元结构;揭示了流域内的水资源以水循环为纽带,相互转化并互相联系;并对山区消耗水量,走廊、盆地、人工绿洲建设引起的地表水与地下水转化的变化和消耗水量的增加,以及内陆河下游水分亏缺问题作了分析评价;并提出了要传递流域水循环整体概念、评价山区与平原绿洲之间的局地水循环、实现在西部开发中实施内陆河流域综合治理的良性循环等问题的讨论。 This paper dissects formation of water resources in mountain areas, scatter and disappear of water resources in plain areas and duality composition in artificial oases etc main features of water cycle in the inland river basins of Hexi Region through analysis of water cycle in the inland region of Northwest China. It is revealed that the water resources of the basin is transferred and related each other in water cycle. Moreover the water consumption in mountain areas, the transformation between surface water and groundwater and consumption increase caused by the artificial oases construction in the Hexi Corridor, and the water shortage of down streams in the inland river basins are quantitatively analyzed. Discussions of delivering entire concept of water cycle in the river basin, evaluating local water cycles between mountain and plain areas, and achieving a virtuous cycle in comprehensive rehabilitation of inland river basins of the West-China development are put forwards finally.
