摘　　要：研究了未来石河予垦区气温上升1℃和2℃对主要作物需水量的影响。结果表明，气温上升1℃和2℃后3—10月ETo增加幅度为6．60％和13．74％，6月受气温影响最明显。气温上升显著增加棉花、玉米、春小麦和冬小麦4种作物需水总量。气温上升，灌溉次数增加，尤其气温上升2℃时，4种作物都会增加1～2次灌溉。按照2008年播种面积计算，气温上升1℃和2℃时灌溉水量将分别增加0．76×108m3和1．57×108m3，其中6月灌溉用水供需矛盾将更加突出。The effects of future temperature rlsutg vy crops in Shihezi area were studied. The results showed that the increasing rates of ETo from March to Oc- tober were 6.60% and 13.74% under the temperature rising by 1 ℃ and 2 ℃, and the top appeared in June. The water requirements of cotton, corn, spring wheat, winter wheat increased by 70. 14 mm, 61.25 mm,65.77 mm and 80.57 ram, respectively under the temperature rising by 2 ℃. Irrigation water amount increased with the increase of temperature and the irrigation frequency of four crops increased by one or two when the temperature increased by 2 ℃. According to the sowing area in 2008, irrigation water amount would increase by 0.76×108m3 and 1.57 ×108m3 the temperature rose by 1℃ and 2 ℃, which aggravated the contradiction between irrigation water supply and irrigation water demand.
