Summary:This is the first introduction of multimode system theory for risk assessment of earthquake-induced landslide. The paper defines the small watershed as multimode system which included triggering system and environmental system, through studying the relationship between multimode system and risk assessment of earthquake-induced landslide. Then the paper evaluates the risk of earthquake-induced landslide in 138 small watersheds with the multimode system, and verifies the result with the landslide data from interpretation of unmanned plane image. The result indicates 67.01% area of landslide in extremely high and high hazard levels. The structure and function of risk assessment model of multimode system is consistent with the formation mechanism of earthquake-induced landslide, which could avoid and decrease the artificial and random in dividing the evaluation index and risk degree of landslide.
