Abstract: 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.
