摘　　要：受罕见华西秋雨影响,2021年黄河中下游发生了严重的秋汛洪水。面对汛情,黄河水利委员会按照“系统、统筹、科学、安全”的原则,以全面均衡洪水蓄泄空间、合理共担洪水风险为调度理念,通过精细化调度水工程,将花园口站2次流量在10 000 m^(3)/s以上的洪水削减至4 800 m^(3)/s左右,成功抗御了此次秋汛洪水。秋汛期间没有发生重大险情、重大灾情、人员伤亡,保证了洪水安澜入海,避免了下游滩区140万人转移和26.6万hm^(2)耕地受淹,保障了下游滩区人民群众生命财产安全。通过简述2021年黄河秋汛洪水调度情况,总结了此次洪水处理策略,提出了对于做好秋汛洪水调度防御的认识。Affected by the rare autumn rain in West China, severe autumn floods occurred in the middle and lower reaches of the Yellow River in 2021. In the face of the flood situation, in accordance with the principle of “system, overall planning, science and safety”, with the concept of comprehensively balancing flood storage and release space and reasonable sharing of flood risk as the dispatching concept, through the fine dispatching water project, Huayuankou twice more than 10 000 m^(3)/s flood had been reduced to about 4 800 m^(3)/s, successfully fighting the autumn flood. During the autumn flood season, there were no major dangers, major disasters or casualties, ensuring the safe flow of flood waters into the sea, preventing the displacement of 1.4 million people and the inundation of 266 thousand hectares of farmland in the downstream flood-plain, and ensuring the safety of people’s lives and property in the downstream flood-plain. This paper briefly introduced the situation of autumn flood control in 2021, summarized the concept of this flood control, and put forward the understanding of doing a good job in autumn flood control and prevention.
