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

摘要： 国内流域梯级水电站坝群安全和应急管理体制和机制缺乏。为预防和应对黄河上游流域坝群安全突发事件，控制、减轻和消除突发事件不利影响，国家电投集团黄河上游水电开发有限责任公司（简称黄河公司）开展了黄河上游流域龙羊峡至刘家峡河段13座梯级水电站坝群安全与应急专题研究，应用风险分析分级矩阵法和风险防控理论，提出了适合黄河上游流域多业主方管理模式的坝群安全应急体制机制方案。本研究对黄河上游流域梯级水电站坝群防灾减灾，保障流域沿岸人身和财产安全、国家安全、生态环境安全具有重要意义，可为其他流域梯级水电站坝群安全与应急管理提供借鉴。
