[目的
]
分析西北干旱区农业耗水的变化情况以及对其产生的影响,以期为于田绿洲未来发展提供指导。[方法
]
利用新疆维吾尔自治区于田县1980—2018年的气象数据及1990和2018年土地利用/覆盖数据,分析得出于田绿洲的耗水特征。[结果
]
①研究区的气候变化总体呈现出明显暖湿的趋势;土地利用/覆盖变化主要表现在绿洲耕地面积的增加,而水域面积则呈现减少趋势;②于田绿洲克里雅河径流量呈现显著上升趋势,年平均经流较之前增加了6.00×10

]
气温的增加造成绿洲作物蒸散增多,耕地面积的增加更是加剧了耗水情况,这使得于田绿洲的绿水耗水总量表现出逐年增加的趋势。
[Objective] The change of agricultural water consumption in the northwest arid region of China and its influence were analyzed to provide guidance for the future development of the Yutian oasis.[Methods] Using the meteorological data from 1980 through 2018 and the land-use/cover data from 1990 and 2018 in the Yutian County
Xinjiang Wei Autonomous Region
the water consumption characteristics of the Yutian oasis were analyzed.[Results] ① The climate change in the study area showed a clear warming and humidity trend. The land-use/cover change was mainly manifested in the increase of the cultivated land area of the oasis
whereas the water area showed a decreasing trend. ② The runoff of the Keriya River showed a significant upward trend in the Yutian oasis
with an annual average flow that was 6.00×108 m3 higher than before
and the water consumption of agricultural green water also showed an increasing trend. It was 1.78×109 m3 higher than that in 2000.[Conclusion] The increase of temperature resulted in an increase of crop evapotranspiration
and the increase of cultivated land area aggravated the water consumption
causing the total water consumption of Yutian oasis to increase annually.
