黄土高原小流域产沙量计算方法研究；

Studying the calculation of sediment yield from a small watershed in the Loess Plateau .

利用流域产沙量与流域面积的关系，估算了燕山地区不同岩性流域的侵蚀模数和泥沙输移比。

An estimate of the amount of erosion sediment and delivery ratio from those small drainage basins has been made by establishing a relationship between sediment yield and drainage area and using a " reference drainage basin " .
