摘　　要：本文采用新疆艾比湖流域3个气象站点的观测资料和MOD16产品数据,通过对蒸散发(ET)、降水量(P)和湿润指数(K)的时空特征分析,得到以下结果:艾比湖流域蒸散发量的空间分布呈现西南部大于东北部,高海拔区大于低海拔区的特征;主要气象因子年际变化情况为温泉站降水量上升幅度最大,阿拉山口站平均风速下降幅度最大,平均气温3个站点上升趋势均不明显,平均相对湿度3个站点均为下降趋势。Based on the observation data and MOD 16 product data of 3 meteorological stations in Xinjiang Lake Basin, the spatial and temporal characteristics of evapotranspiration（ET）, precipitation（P） and wetting index（K） were analyzed. The following results were obtained： the spatial distribution of evapotranspiration in the Ebinur Lake Basin showed that the southwest was larger than the northeast and the high altitude is larger than the low altitude area; the annual variation of the main meteorological factors was the maximum increase of the precipitation in WenQuan Railway Station, the maximum decrease of the average wind speed, the rising trend of the average temperature of three stations was not obvious, and the average relative humidity of the three sites were all declining.
