Abstract: There is a lack of safety and emergency management system and mechanism for cascade hydropower stations in China. To prevent and respond to safety emergencies of dams in the upper reach of Yellow River basin, and to control, mitigate and eliminate adverse effects of emergencies, study on the safety and emergency management of 13 hydropower stations in the reach from Longyang George to Liujia George was carried out by State Power Investment Group Huanghe Hydropower Development Company Limited. The analysis of risk classification matrix and the theory of risk prevention were used to establish the dam safety and emergency management mechanism suitable for hydropower stations in the upper reach of Yellow River belonging to different owners. The study results were of great importance and worthy reference.

Key words: cascade hydropower stations, dam group safety, risk prevention and control, emergency mechanism
