摘　　要：为了确定野外试验场场址由地表向地下土壤渗入的水量 ,必须计算场址的地表蒸发量。在野外试验场安装了环境气象自动监测装置 ,每 10分钟自动记录一次监测数据 ,观测历时二年多。将所获取的气象数据和有关参数用 Penman法、能量平衡法、迭代法和湍流相关法四种方法计算了土壤蒸发量 ,计算结果表明 ,试验场址的土壤年蒸发量与降水量基本一致 ,在 4 0 0～ 6 0 0 mm/ a之间。In order to determine the infiltration rate of the surface water in the field, it is necessary to calculate the evaporation. Four methods are adopted to calculate the evaporation at CIRP's Field Test Site. An environment monitoring system recorded the observed meteorological data. Observation was conducted for two years. The system samples data every ten minutes and transfers data to a personal computer automatically. Evaporation rate was calculated with Penman, energy balance, iteration and turbulent flux method. The results indicate that the annual evaporation at the site is equal to the precipitation approximately, ranging from 400 mm to 600 mm per year. (
