In mountainous areas， most of highways are built by cutting mountains and filling valleys. Due to the lack of ecological protection awareness at the early stage of construction， many bare high and steep rock slopes are exposed along the highways， leading to various geological disasters， especially collapses， landslides， debris flows and other disasters. In this paper， a geological hazard point of collapse along the 302 Provincial Highway （Maanshan village section， Linzhou city， Henan province） is taken as an example， with full understanding of the engineering geological conditions， hydrogeological conditions， joint development and stability of the collapse dangerous rock mass， the theory of ecological protection and restoration is adopted to integrate the geological disaster prevention and control system for collapse into ecological landscape planning， so as to improve the self-recovery ability and protection function of the ecological system in the treated area， achieving the purpose of ecological landscape restoration through disaster prevention and reduction.
