【摘要】 有效阻止泥沙下坡入沟是减少江河泥沙的主要途径之一。利用抗冲水槽对坡面油松植被过滤带枯落物层对含沙水流的影响进行了研究。结果表明,枯落物层拦截泥沙的作用显著,并且随着植被过滤带宽度的增大,枯落物层的拦截泥沙量呈自然对数函数形式增加。更多还原

【Abstract】 To prevent sediment effectively from slipping down slope into gully is a major way to decrease the sediment in rivers. This paper deals with the effect of litter-buffer strips on concentration flow. The study result shows that the sediment trapping effect of litter-buffer strips on concentration flow is remarkable. Between the width of the buffer strip and the trapped sediment exists a natural logarithm relation.更多还原
