downslope flow 中文意思是什麼
downslope flow
解釋
下坡氣流-
( 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，再分佈過程中，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，由於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。 -
( 4 ) wavy distribution of soil water along hillslope resulted from the fluctuation of runoff, upslope runoff infiltration, lateral downslope flow, and the difference of infiltration rate and evapotranspiration
（ 4 ）土壤水分沿坡面呈「波浪形」分佈是坡面徑流的波動性、上方來水（徑流）的沿程入滲、側向沿坡向下流以及坡面各處入滲性能和蒸發蒸騰作用的差異等綜合作用的結果。
