根据玉树州1961年～2000年实测资料系列，分析了玉树州40年间水面蒸发量的变化趋势；并利用相关分析技术和通过t检验在0．05和0．01的置信水平下，分析了水面蒸发量与地面温度、降水等9种气象因素之间的相关关系。分析结果表明：玉树州在40年间蒸发量呈上升趋势，影响蒸发的主要因素为平均温度、平均云量、日照时间。

Based on the measured data during1961~2000 in Yushuzhou ,the trend of evaporation change in Yushuzhou in recent 40 years is analyzed ,and the relations between potential evaporation and average ground temperature are also analyzed as well . It is found out that the increasing trend of potential evaporation change exists in Yushuzhou in 40 years and important factors that affect potential evaporation are average air temperature ,average cloud and sunlight time .
