流域产沙量演变规律的研究对于工程设计、水土流失规划与治理具有重要作用。
The research on evolvement law of drainage basin sediment yielding plays an important role in design of a project, planning and control of soil erosion.
黄河流域“水沙异源”特点明显，中游水土流失严重地区产流量和产沙量分别占到流域产流量的10%和70%左右。
The sources of sediment and water are different and the sediment and water coming from the middle reaches of the Yellow River Basin account for 10% and 70% of that of the whole basin.
结果，计算所得到的小流域产流量和产沙量值与实测值相差只有1.1%和4.4%，说明方法合理。
Difference between calculated value and observed value of runoff and sediment generation is 1.1%and 4.4% respectively. The results showed that this method is reasonable.
