采用小型沟间降雨模拟装置，研究了降雨强度、土壤强度和坡度对沟间侵蚀的影响。在细纹间剥离与降雨强度的关系表达式中，坡度对强度指数没有交互作用。沟间土壤的可蚀性与降雨后土壤抗剪强度密切相关。利用包含降雨强度、坡度和土体抗剪强度的预测方程可以很好地预测沟间土壤侵蚀。
A small interrill rainfall simulator was used to evaluate the effects of rainfall intensity, soil strength and slope on interrill erosion. There was no interaction effect of slope on the exponent of the intensity in an expression relating interrill detachment to rainfall intensity. Interrill soil erodibility was closely related to soil shear strength after rainfall, as measured by a vane shear device. Interrill soil erosion was well estimated by a prediction equation that included rainfall intensity, slope and soil shear strength.
