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 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。
