为了解决中国西北干旱区社会经济需水和生态环境需水的矛盾,应用干旱区平原绿洲耗散型水文模型,研究1992—1996年新疆渭干河平原绿洲水资源消耗过程及其组成。结果是:渭干河绿洲每年耗水约20.5亿～26亿m3;农业区的年均陆面蒸发为620～660mm,自然生态系统年均陆面蒸发为320～400mm;在绿洲耗水中,社会经济系统约占60%～65%,自然生态系统约占35%～40%;作物生长期为非充分灌溉供水。模型模拟和实测结果比较吻合,表明该模型在干旱区有一定的适应性。
In order to solve the contradiction between socioeconomic water demand and eco-environmental water demand in arid areas of northwestern China, the paper uses the dissipative hydrological model of arid plain oasis to study the water consumption process and its composition of the Wegan dry plain oasis in Xinjiang from 1992 to 1996. As a result, the annual water consumption of Weigan River oasis is about 2.05 billion to 2.6 billion m3. The average annual land surface evaporation of agricultural areas is 620-660 mm, and the average annual land surface evaporation of natural ecosystems is 320-400 mm. In oasis water consumption, Economic system accounts for about 60% ~ 65%, natural ecosystem accounts for 35% ~ 40%; crop growth period is inadequate irrigation water supply. The model simulation and measured results are in good agreement, indicating that the model has some adaptability in arid area.
