Abstract: In order to analyse the influence of topographic parameters on the motion parameters of slope-toe landslide including maximum horizontal movement distance (L_max), horizontal movement distance beyond slope toe (L) and equivalent friction coefficient (f), the non-linear statistical model is used to establish the motion parameters models of different landslide scales for the inversion analysis. The main results of inversion analysis are as follows:(1) The discrepancy in elevation of landslide (H) and slope gradient (α) have significant influence on L_max, L and f under different landslide scales. (2) With the increase of landslide scale, the influence of angle of slope-toe (β) on L_max and L is gradually weakened which indicates that the blocking effect of slope toe is weakened, but the influence of angle of slope-toe (β) on f is gradually increased. (3) With the increase of landslide scale, the influence of slope of accumulation area (γ) on L_max and f is gradually increased, which indicates that the micro geomorphic effect of the accumulation area is significantly enhanced. Finally, the prediction model of the maximum horizontal movement distance considering the main terrain parameters (H, α, β, γ) and landslide scale (V) has higher prediction accuracy and certain applicability.
