摘要: 利用1961-2000年阿拉尔气象站逐日蒸发皿蒸发量资料,揭示了该区域蒸发量年内、季节和年际变化特征及其趋势。结果表明:近40 a新疆阿拉尔垦区蒸发量总体呈减少趋势,其倾向率为-78.68 mm/10 a,逐月蒸发量均有不同程度减少的趋势,温暖时期蒸发量减少比寒冷时期更加明显。

Abstract: Based on the daily pan evaporation data from 1961 to 2000 in Alar weather station, the characteristics and trends of the seasonal, annual and inter-decadal changes were analyzed in Alar irrigated area. The results indicate that evaporation is the decreasing trend in recent 40 years with -78.68 mm/10 a. And monthly evaporation is also the decreasing trend. Compared to that in cold period, the decrease of evaporation in warm period is obvious.
