| 摘 要： | 根据阿克苏上游水库1982—1987年,塔门镇2000—2002年同步观测的20m2水面蒸发池和直径20cm小型蒸发器水面蒸发资料,估算了直径20cm小型蒸发器对20m2水面蒸发池的水面蒸发折算系数,分析了其变化特征,并与北疆哈地坡及我国新蒙区年水面蒸发折算系数进行了对比。结果表明,塔里木盆地冻结期(4~10月)的水面蒸发虽然微弱,但不能忽略,水面蒸发折算系数在非冻结期逐月增大,年际变化较小,但呈现逐年下降的趋势。该结果可供塔里木河流域水量平衡研究、水资源评价、生态需水计算时参考。 |

| Abstract: | The paper evaluated the evaporation conversion coefficient from 20 cm pan to 20 m~(2) pool based on the climate data synchronously observed in Shangyou reservoir from 1982 to 1987 and in Tamen town from 2000 to 2002; analyzed the coefficient s changing characteristics. The evaporation conversion coefficients of the above two regions are compared with that of Hadipo in north Xinjiang and that in Xinjiang-Mongolia region. The results showed that the water surface evaporation intensity is small during the freezing period, but can't be neglected. The conversion coefficient increases month by month during the freezing period, yearly change is small, but has a trend of decreasing year to year. The study results can provide references for water balance research, water resources evaluation, and ecological water demand calculation in Tarim river basin. |
| Keywords: | conversion coefficient 20 cm evaporation pan 20 m~(2) evaporation pool water surface evaporation Tarim river basin |
