英文摘要	Irrational allocation of irrigation water resources aggravates water shortages, affecting the sustainable development of agriculture, especially in arid regions. The expansion of the cultivated area in the middle Heihe river basin (HRB) will not necessarily increase the water consumption, despite the increase in the water-saving irrigation area. In this study, the temporal and spatial distribution, and the driving factors related to water consumption, including evapotranspiration (ET), transpiration (T), evapotranspiration ratio (T/ET), and precipitation deficit (ET-P), were investigated in the middle HRB using linear trend, piecewise fitting, and multiple linear regression method. The results show that the 97 WDS has prominent impacts on the temporal and spatial trends and the driving factors in ET and Tin the middle HRB. Water consumption does not necessarily increase under the centralized water allocation with improved irrigation efficiency and increased cultivated area. The result provides new evidence for increasing T/ET to decrease water consumption in response to the expanding cultivated area, while helping decision-makers to reduce water consumption in the middle HRB, and evaluate 97 WDS.
