| 摘 要： | 水面蒸发量计算是水文水利计算、径流预测预报、水资源调查评价等工作中必不可少的内容，是一个地域主要的水分支出项，与一个地域的水分收入项降水量，共同决定了一个地域的湿润状况，因此水面蒸发的研究是一项十分重要的工作。水文部门的蒸发站在结冰期使用D-20蒸发皿，非结冰期使用E-601蒸发器或80 cm套蒸发皿来测定水面蒸发量。文章采用了折算系数，折算成E-601并分析了水面蒸发量的时空变化规律。

| Abstract: | Calculation of water surface evaporation is an essential work for hydrology and water conservancy calculation,prediction of runoff,water resources investigation and assessment,and main water consumptions.It determines the moist of a region,combining with the precipitation of water income in a regional.Therefore it is a very important task to study the water surface evaporation.Hydrological departments are using the D-20 pan in a frozen period,E-601 or 80cm evaporator pans in ice-free period to determine surface evaporation,conversion coefficients is used and converts to E-601 and the spatial and temporal variation law of water surface evaporation is analyzed in this paper. |

| Keywords: | water surface evaporation evaporating dish conversion coefficient data series regional distribution law of temporal and spatial variation |
