A good relation between evaporation and water content of topsoil and the topsoil water content could be used to infer soil evaporation. A numerical model SWEAT was used to simulate evaporation, soil water, and soil temperature and the hydrological characteristics of soil and time dependent weather data were used as input.

根据1993年在英国Reading大学Sonning农场进行的试验,对直接测定土壤蒸发的micro-lysimeter的应用进行了评价。结果表明,砂土蒸发呈阶段性特征,蒸发与表层土壤含水量有很好的相关性,因此可用表层土壤含水量来推测土壤蒸发。同时用SWEAT模型模拟土壤蒸发、土壤水分和土壤温度,用土壤的水文特征常数和气象资料作为输入。模拟数据与同期用micro-lysimeter测定的数据相比较,测定期间18d的累积蒸发量相差在0.7mm以内,0~23cm剖面上的土壤贮水相差在4mm之内,但模拟的土壤温度比实测偏高,特别在清晨。可以认为micro-lysimeter法是测定土壤蒸发的一种有效方法,SWEAT模型可以精确地模拟裸土土壤蒸发速率和土壤湿度剖面,但不能很好地模拟土壤温度剖面

The large scale weighing lysimeter and micro lysimeter are employed to determine the daily alteration processes of evapotranspiration and soil evaporation of winter wheat in its growth stages. According to the observation data, the authors found that about 30% of the total field evapotranspiration is consumed by the soil evaporation under canopy. Furthermore, the water saving farming can be expressed as increasing leaf area index (LAI) in the early stage of growth and controlling topsoil moisture under...

The large scale weighing lysimeter and micro lysimeter are employed to determine the daily alteration processes of evapotranspiration and soil evaporation of winter wheat in its growth stages. According to the observation data, the authors found that about 30% of the total field evapotranspiration is consumed by the soil evaporation under canopy. Furthermore, the water saving farming can be expressed as increasing leaf area index (LAI) in the early stage of growth and controlling topsoil moisture under the canopy. Based on the evapotranspiration determination the dimensionless crop coefficient can be calculated.
