黄河冰凌洪水突发性强、涨势猛、持续时间长,产生的灾害有时更甚于暴雨洪水。人民治黄以来,经过50年的努力,初步建成了黄河防凌体系.以干流水库、堤防、分凌工程组成的工程体系,是防凌体系的主体;非工程措施主要包括人民防凌队伍、冰情测报预报和防凌调度系统、分凌区管理等,是防凌体系的重要组成部分。50年来,对黄河冰凌运行规律、水库防凌调度及防凌决策支持系统的研究有了较大进展,为做好黄河防凌工作奠定了基础.今后,小浪底等干流水利枢纽工程建成后,将为黄河的防凌安全提供更大的保证.
The flood and flood in the Yellow River are sudden and intense, and the momentum is fierce and the duration is long. The disasters produced are sometimes more severe than the storm and flood. Since the people’s rule of the Yellow River, after 50 years of hard work, the Yellow River anti-iceling system has been basically built. The project system consisting of main stream reservoirs, embankments and sub-Ling projects is the main body of the anti-sprinkling system. The non-engineering measures mainly include the people’s anti-splintering team, the forecast and forecasting system of ice conditions and the anti-sprinkling system and the management of Fenling District, which are important components of the anti-sprinkling system section. Over the past 50 years, great progress has been made in researches on the law of the operation of the ice impounding of the Yellow River, the deployment of anti-flood control and the decision support system for reservoirs, laying the foundation for doing a good job in preventing the flood in the Yellow River. In the future, Xiaolangdi and other major water conservancy projects are completed, the Yellow River will provide greater protection against safety.
