摘　　要：土壤蒸散发量的计算,在墒情预报、降雨径流计算及水资源评价中都占有重要的地位。利用水力式土壤蒸发器及其配套的气象、辐射、水面蒸发仪器观测资料,综合考虑“土壤—植物—大气”系统中的各个因素对土壤蒸散的影响,建立了适于黑龙港流域的土壤蒸散量计算模型。Calculation of quantity of soil evaporation takes an important part in moisture content prediction, rainfall surface flow calculation and evaluation of water resources. To utilize hydraulic soil evaporimeter and supporting meteorology, radiation , the materials on the surface water evaporation, considering the influence of each factor of ＂soil-plant-atmosphere＂ system on soil evaporation, we set up calculating model of the soil evaporation which is suitable for the Heilonggang region.
