运用野外人工模拟降雨方法研究了黄土丘陵区人工草地径流起始时间(tp)与降雨强度(I)、草地盖度(C)以及土壤前期含水量(W)之间的关系。结果表明,(1)当有草体覆盖时,tp主要与I和C有关,(2)当无草体覆盖时,tp与I和W有关;(3)tp与I以及与C、W间分别存在幂函数和线性相关关系。

为了探究人工降雨模拟试验结果的相似性,通过文献数据和观测数据,分析了人工降雨模拟试验与天然降雨小区观测在径流、泥沙方面的差异及其原因,从数值和规律2方面深入讨论了室内模拟降雨试验结果的相似性问题。结果表明:(1)模拟降雨试验弱化了降雨因子对坡面径流和泥沙的影响,且雨强/雨量或降雨侵蚀力越小,模拟试验的相似性越差。(2)模拟降雨试验中产流和产沙随坡度的变化规律明显不同于天然降雨观测情况。(3)在坡面条件和降雨作用相同的情况下 ...

用人模拟降雨仪研究了我国亚热带7种有代表性土壤的可蚀性,结果表明土壤可蚀性因子K值以紫色土最高,第四纪红色粘土发育的土类最低,该文还用诺谟方法估算了土壤可蚀性因子K值,但其中大部分与人工模拟降雨仪测得的相差较大,因此,认为该地区极大多数土壤类型不能直接用诺谟图方法来估算土壤可蚀性因子K值。
