sediment-delivery ratio 沉积物输送比值
sediment delivery ratio sdr 泥沙输移比
channel sediment delivery ratio 河道泥沙输移比
From long term point of view, sediment delivery ratio of a drainage basin with a control degree reaching 70% can be reduced by around 50% in contrast to pre control conditions. The effect of erosion control is quite significant.
从长期来看 ,在治理度达到 70 %条件下与治理前相比泥沙输移比减小 50 %左右 ,治理的效益是十分显著的。

The sediment delivery ratio is not correlative with the river basin area, because which is not a influence factor but a units of measurement.
流域泥沙输移比与流域面积不存在固定的线性关系，其根本原因在于流域面积是度量衡单位，而不是影响因素。
The dramatic change of sediment delivery ratio 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。
This paper reviews the previous studies on the relationship between sediment delivery ratio 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。
