在分析了金沙江下游地区泥沙资料的基础上，指出金沙江下游泥沙的地区分布、沿程分 布、年内变化和年际变化均受泥石流活动的时空控制，并提出了输沙模数的计算公式和不同地 区的计算参数． Based on the analysis of the sediment data in the lower reaches of the Jinsha River, it is pointed out that the distribution of sediment in the lower reaches of the Jinsha River, its distribution along the journey, the annual variation and the interannual variation are both controlled by the time and space of debris flow activities. Calculation formula and calculation parameters in different regions.
