To apply the concept of ecological restoration to repair landslide, we propose new illustrations to clarify the trajectory and goal of landslide revegetation expressed in terms of the two major characteristics of ecological structure and function. Traditional vegetation engineering methods can quickly recover fundamental ecological functions such as biomass and vegetation cover ratio, but are inadequate when it comes to recovering ecological structures such as stratum and biodiversity. The future goal of landslide restoration should be extended from establishing grass vegeta- tion simply for slope stability and erosion reduction to developing early-s
