This study focused on the mechanisms of landslides which occurred in the headwater watershed to establish the index of potential headwater landslides. The index of potential headwater landslide is defined as a ratio of the amount of channel sediment output to the slopeland sediment yield for a given storm event in the headwater watershed. The spatial distribution of headwater watershed was delineated in the interested watershed according to the rule of Strahler's stream order and a conceptual model (index of potential headwater landslide) is introduced to quantitatively measure the potential headwater landslide for the references of policy and decision making.
