  1. ( 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。

  3. At present, the studies about the controlled alternate furrow irrigation are focused on how it affects the water physiological indexes, water consumption and yields of crops. but, some problems suc h as the soil infiltrative parameters, irrigating water advancing, water redistribution in soil, calculation of crop water requirement and water consumption, and the upper and lower limit indexes of soil moisture, guiding a field irrigation after the controlled alternative furrow irrigation is implemented in field, have not been researched systematically and deeply. if these problems could not been solved commendably, the popularization of controlled alternate furrow irrigation will be affected

    然而,目前有關交替隔溝灌溉的研究還主要集中於這種灌水方式對作物水分生理指標、耗水量和產量的影響方面,而對大田採用這種灌水式后的土壤入滲參數變化情況、作物需水量與耗水量計算、以及指導大田灌溉的水分下限控制指標等與大田生產實際密切相關的幾個問題基本上還沒有進行系統的深入研究,而這些問題如不能得到很好地解決,勢必會對這種灌水方式的推廣應用產生嚴重的影響。

  6. In this dissertation, rainfall infiltration, runoff, and soil water redistribution on a hillslope were studied by simulated rainfall experiments, and soil water cycling was investigated by site observation and soil sampling methods. moreover, the reasons for the desiccation of deep soil layer were analyzed, and its assessment indexes and standards were presented. the main results are as follows : ( 1 ) rainfall infiltration into a planar hillslope with a homogeneous isotropic soil could be simply regarded as one - dimensional infiltration process, if soil erosion was prevented

    針對當前該區植被恢復重建中存在的科學問題,以植被建設的關鍵性限制因素?土壤水分為出發點,通過室內外模擬降雨試驗,研究了坡地降雨入滲、產流及土壤水分再分佈規律,同時採用定位觀測和采樣分析相結合的方法,分析了坡地土壤水分的循環與轉化特徵,並初步建立了深層土壤乾燥化程度的評價標準,取得的主要結論如下: ( 1 )在防止土壤侵蝕的條件下,均質坡地的降雨入滲過程可以簡化為一維。
