中文摘要：

通过室内土柱蒸发试验对蓄水坑灌条件下土壤蒸发规律进行研究,结果表明,同一湿润锋埋深水平时,不同光照强度下土壤累积蒸发量随光照强度降低而降低,并呈指数分布;同一光照强度下不同湿润锋埋深水平时,土壤累积蒸发量随湿润锋埋深减小而增加,并呈乘幂曲线分布。同时对蒸发时蓄水坑灌条件下土壤水分运动机制进行了分析。

英文摘要：

Through the experiment of soil column in lab,researching the disciplinarian of soil evaporation under water storage pit irrigation condition,the results showed： under the same levels of wetting front in soil profile and different light intensity,the decrease of soil accumulation evaporation along with the decrease of light intensity and their relation is exponential.Under the same light intensity and the different levels of wetting front in soil profile,the increase of soil accumulation evaporation along with the wetting front in soil profile became shallow and their relation is power.In addition,the mechanism of soil moisture movement was analyzed.
