The genetic types of landslide and debris flow disasters are brought forward basede on inventory of 160 cases collected in 1920~2013 in China and combined more than 30 years from author's research experiences. Landslide disasters are divided into 10 types that consists of rainfall sliding, earthquake breakdown, natural sliding, frost melting collapse, underground excavation sliding, cut slope relaxing action, soil fill loads pushing, reservoir watertable fluctuation and infiltration, irrigation seepage and blasting vibration types. Basic property of each type of landslide disaster is described that involve with deformation mechanism, failure model, movement feature, endangering modes and its representative cases. Debris flow disasters are classified into 7 types that consist of ravine evolution, slope soil liquefaction, landslide dam breaking, engineering discard soil burst, tailings dam breaking, ice lake dam burst and soil deposit slipping—eroding types. Basic property of each type of debris flow disaster is described that involve with main induced factors, startup models, movement property and harmful modes. This classification scheme is aimed at rapid jugement of slope hazards for to provide technical support in decision making and to set up a basis for to develop an emergency response system.
