Abstract: Debris flow risk is expressed as the product of debris flow hazard and debris flow vulnerability. Debris flow risk management is to reduce or to shift debris flow risk. Generally there are three ways to manage debris flow risk：to reduce debris flow hazard, to reduce debris flow vulnerability and debris flow insurance. In practice of the risk management, the above three ways usually are comprehensively taken to reduce and to shift debris flow risk. Debris flow risk is also associated with the land use planning in debris flow prone areas. Thus Debris flow risk assessment and management can provide the scientific supports for the sustainable use in the prone areas of debris flows.

Key words: debris flow, risk management, land planning
