摘要
黄河秋汛洪水相比夏汛洪水,具有洪峰低、持续时间长、含沙量低的特点.2021年黄河发生严重秋汛,干支流、中下游汛情多区域交织,多场次叠加,洪量之大、历时之长,历史罕见.文章以2021年黄河秋汛洪水为例,从水库群精细联合调度、洪水防御工作部署、防洪调度成效等方面回顾了秋汛洪水防御工作,总结了此次洪水防御过程中的技术支撑及组织保障经验,展望了新形势下秋汛洪水防御工作重点,为今后秋汛洪水防御工作提供借鉴参考.
Abstract
Compared with summer floods,the autumn floods of the Yellow River are characterized by low flood peak,long duration,and low sand content.In 2021,the Yellow River experienced severe autumn floods,which intertwined and re-peated in multiple regions along the trunk and tributaries as well as the middle and lower reaches.The large volume and the long duration of the floods were rare in history.Taking the autumn floods of the Yellow River in 2021 as an example,this paper reviews the autumn flood control from the perspectives of refined joint dispatching of reservoir groups,deployment of flood control,and achievements of flood control scheduling.It summarizes the experience in technical support and organiza-tional guarantee in flood control,and outlines a vision for the key points of autumn flood control under the new situation,which provide reference for future autumn flood control.
