摘　　要：分析艾比湖湖水蒸发量,可为艾比湖最优运行水位的确定提供依据。根据阿拉山口气象站和精河气象站的测量资料,对艾比湖195 m水位以下的湖水蒸发量进行计算。结果表明,从5月份开始艾比湖湖水蒸发量迅速增加,7月份达到最高值,为1064.1mm,9月份呈现下降趋势;艾比湖5—8月的湖水蒸发量占全年湖水蒸发量的67%,且这一时期受气候、农林牧业用水的影响,湖面水位下降快,干涸速度加快。建议从4月份开始设法逐渐增加入湖水量,以补充、平衡艾比湖逐月增加的湖水蒸发量。In order to rationally analyze the evaporation from Ebinur Lake and to provide a scientific basis for determination of the optimal operational water level of the lake,the lake evaporation below the elevation of 195 meters was calculated based on observed data from the Alashankou and Jinghe meteorological stations.The results show that the lake evaporation rapidly increased from May onwards,reached its highest value of 1064.1 mm in July,and showed a downward trend in September.The lake evaporation from May to August accounted for 67% of the annual evaporation,and in this period the lake＇s water level declined rapidly and the drying speed intensified due to the impacts of climate and water utilization in the sectors of agriculture,forestry,and animal husbandry.It is suggested that from April onwards we should try to gradually increase the volume of water flowing into Ebinur Lake in order to supplement the lake evaporation and maintain the water balance of the lake.
