摘　　要：在水文计算与水文预报中,蒸发量与蒸发能力的确定是十分重要的环节。本文按无雨、降雨小于蒸散发能力、降雨大于蒸散发能力3种情况分别计算蒸散发量,提出了确定流域蒸散发能力的新方法。The determination of evaporation amount and potential evapotranspiration is an important lank in hydrological calculation and hydrological forecast. The paper calculates respectively the evaporation amount under tree conditions of no rain, rain less than potential evapotranspiration rain greater than potential evapotranspiration, sets forward a new method for determining potential evapotranspiration in the river basin.
