黄土高原沟壑区坡耕地土壤入渗规律研究
Research on Soil Infiltration Law of Slope Farmland In Gully Area of Loess Plateau
【摘要】 通过野外人工模拟降雨试验 ,分析了 3种入渗公式中经验参数在坡耕地不同耕作措施、不同坡度及不同降雨条件下的变化规律 ,探讨了坡度、土壤初始含水率、降雨强度、不同耕作措施对土壤入渗的影响
【Abstract】 The laws of the experiential parameters in three infiltration equations with tillage measures,slope gradients and rain conditions of slope farmland were analyzed.The different law of the soil steady infiltration rate and rainfall-runoff time have been approached from the different slope gradient, antecedent soil moisture, rain intensity and different tillage measures.
