摘　　要：采用分段风速函数建立了黄河巴彦高勒蒸发实验站的道尔顿水面蒸发模型,计算结果表明:当风速小于3 m/s时,模型计算蒸发量与实测蒸发量相关关系很好,可基本消除水面蒸发经验公式在不同风速段出现不同系统性误差的现象;风速大于3 m/s时,模型计算结果不太理想。Dao＇erdun model of water surface evaporation is established applying subsection wind speed function in Bayangaole evaporation experimental station on the Yellow River.It is showed in the result that the correlativity between the computation by model and the observation is very well when wind speed is less than 3 m/s,and the phenomenon of different systematic error in different wind speed brought by experienced formula can be avoided basically;while when wind speed is higher than 3 m/s,the simulation result is not perfect due to the relatively dispersed observed points.
