An Application of the Light Evaporograph in the Study of Soil Evaporation of Forest Land

结果表明：与单作相比，间作麦田土壤蒸发量增加了34.63mm，作物蒸腾量减小了65.81mm，ET值减小了31.18mm；

The results showed that compared with the monoculture , the evaporation of intercropping increased 34.63 mm , transpiration decreased 65.81 mm , evapotranspiration decreased 31.18 mm .

同时，对影响土壤蒸发的外界因素进行了分析。结果显示，气象因素中相对湿度、饱和水气压差和辐射同土壤蒸发有着密切的关系，在P

The study on factors effecting the evaporation of soil shows that the relative moisture , vapor pressure difference and radiation are major factors . They always connected water with their attitude . Study on the Relation between Specific Yield and Saturation Deficiency

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。

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。

An experiment was carried out in 1993 in Sonning Farm , Reading University , UK to evaluate the use of micro lysimeter method for direct measurements of evaporation from a sand soil .

Effects of the different length micro-lysimeters on the evaporation

采用简单实用的Priestley-Taylor公式计算潜在蒸散量，并考虑作物覆盖与残茬覆盖对土壤蒸发与作物蒸腾的影响。

A simplified Priestley-Taylor equation was employed in the model to calculate potential evapotranspiration , and the effect of residue cover on evapotranspiration was also considered .

在33d的试验观测期内，三种处理的蒸发动态不同，覆盖处理的土壤蒸发过程没有集中的蒸发高峰期，而不覆盖处理的土壤蒸发过程主要集中在前10d。

The evaporation dynamic was different in the three soil treatments during the experimental observation for 33 days . The evaporation process had no concentrated fastigium of soil water evaporation in cover treatments , but in non-cover it concentrated in the first 10 days .

地下水位对蒸散量的影响在它小于1.5m时不显著，而在1.5～1.75m之间时，蒸散减小较快，主要由于土壤蒸发减小显著，冠层蒸腾稍有增加。

The response of ET to groundwater table is apparent while water table is between 1.5 ~ 1.75 m depth . When the water table is less than 1.5 m , ET decreases due to less intensity of soil evaporation , whereas canopy transpiration is a little bit enhance .
