sediment delivery ratio

基本解釋

The sediment delivery ratio is not correlative with the river basin area, because which is not a influence factor but a units of measurement.
流域泥沙輸移比與流域麪積不存在固定的線性關(guān)系，其根本原因在於流域麪積是度量衡單位，而不是影響因素。
The dramatic change of sediment delivery ratio is caused by the formation of artificial sediment sinks, i. e. , sediment-trapping check-dams and reservoirs.
泥沙輸移比的變化，主要是由於流域內(nèi)人爲(wèi)沉積滙的形成所致。
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輸移比與流域麪積關(guān)系其實(shí)質(zhì)都是流域輸沙模數(shù)與流域麪積的關(guān)系。

泥沙輸移比
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.
從長(zhǎng)期來(lái)看 ,在治理度達(dá)到 70 %條件下與治理前相比泥沙輸移比減小 50 %左右 ,治理的傚益是十分顯著的。
