| 摘 要： | 通过室内模拟试验,建立了不同吹风时间及吹风强度下的土壤水分蒸发动力学模型,在此模型中,土壤水分蒸发量W与时间对数(1nt)呈直线正相关.吹风时间和吹风强度对土壤水分初始蒸发量影响较大,随着时间推移,影响强度减小.同时对不同水分条件下吹风强度与土壤水分蒸发关系的研究表明,当初始含水量较高时,吹风强度越大,水分损失量越大;反之,水分损失量越小.

| Abstract: | Dynamical models of soil evaporation on the conditions with varied winding time and winding intensity were developed on simulative trial in lab, which inferred that soil evaporation had positive relation with logarithm of time. The influence of winding time and winding intensity on soil evaporation was great, however, it decreased with time going on. Moreover, after studying the relation of soil evaporation to winding time and winding intensity on the condition of varied soil water content, the result was showed that the greater winding intensity, the more water loss when the soil water content was higher vice versa. |
