  流域泥沙輸移比與流域麪積不存在固定的線性關系，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)人爲沉積滙的形成所致。

• 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.
  從長期來看 ,在治理度達到 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。
