In this paper, the formation of water resources in mountain areas, scatter and disappear of water resources in plain areas and duality composition of water resources in artificial oases are discussed, and the water transformation features and interrelation in the water cycle of inland river basins in Hexi Corridor are revealed, through an analysis of the key links of water cycle in the inland in Northwest China. Water consumption in mountain areas, transformation between surface water and ground water, water consumption increase caused by artificial oases construction in the Hexi Corridor, and water shortage in the lower streams in inland river basins are quantitatively analyzed. Finally, an entire concept of water cycle is put forwards to evaluate the effect of water consumption in the front plains, and a conclusion is made of improving water transformation in sustainable utilization of water resources in Hexi inland river basins during the development of the western region of China.
