( 3 ) when evaporation was stopped during the process of soil water redistribution , soil water would move downslope by gravity . when evaporation was in process , due to low initial water content , most infiltrated water from small intensity and amount of rainfall would be consumed by intensive evapotranspiration during rainy season , and lateral downslope unsaturated flow seldom took place . however , soil water would move downslope by gravitational and matric potential gradients after continuous rainfall ( 3 )在防止蒸發條件下,再分布過程中,土壤水分在重力的作用下有沿坡向下運移的趨勢;在蒸發條件下,由于初始含水量一般較低,雨季量小且分散的降雨極易為強烈的蒸發蒸騰所消耗,側向沿坡向下流難以發生,但在持續的降雨條件下,土壤水分在重力勢和基質勢梯度的作用下易沿坡向下運移。 |
