摘      要：The massive 8.0-magnitude Wenchuan Earthquake triggered huge landslides,avalanches,and debris flows that blocked rivers and created 34 important quake lakes,including the Tangjiashan Quake Lake on the Tongkou *** than half of these lakes were identified to be of moderate or high hazard levels,so activities needed to be undertaken for hazard mitigation of potential *** paper presents the mitigation processes of quake lake hazards,which involve various techniques such as rapid hazard analysis,scenario-based mitigation planning,and real-time forecasting of outburst flooding for implementation *** shortage of hydrologic and geological data and the nature of emergency situations raise substantial challenges in the hazard mitigation of quake *** paper suggests a potential approach in dealing with quake lake hazards,which integrates the automatic monitoring network,hydrologic models,and hydrodynamic models with a comprehensive indicator for hazard *** necessity of improving the integrated methodology is highlighted.
