| 摘 要： | 泥沙输移比定义一直存在着不够准确清晰的缺点，对泥沙输移比概念及其影响因素进行了更深入的探讨是非常有必要的。首次在泥沙输移比公式中引入粒径、时段因子，利用量纲分析推求了不同区域的泥沙输移比公式。从理论上阐明泥沙输移比并不是单纯与整个流域面积成反比，而是与流域产沙面积成反比

| Abstract: | Sediment delivery ratio has always not been defined accurately and distinctly.This paper has made further study on the concept and impact factors of sediment delivery ratio.By firstly introducing grain size and duration factors,making use of dimensional analysis,the formula for calculating sediment delivery ratio has been obtained in different areas.It concluded that sediment delivery ratio should theoretically be in inverse proportion to erosive area instead of the whole catchment area. |
