This paper reviews the previous studies on the relationship between sedimentdeliveryratio and drainage area which reflects essentially the relationship between sediment yield and drainage area.
提出至今所有流域泥沙输移比与流域面积关系其实质都是流域输沙模数与流域面积的关系。

The dramatic change of sedimentdeliveryratio is caused by the formation of artificial sediment sinks, i. e. , sediment-trapping check-dams and reservoirs.
泥沙输移比的变化，主要是由于流域内人为沉积汇的形成所致。

The sedimentdeliveryratio is not correlative with the river basin area, because which is not a influence factor but a units of measurement.
