摘　　要：2020年6月底始,受持续强降雨和长江干流顶托倒灌影响,鄱阳湖水位暴涨,发生超历史纪录大洪水。基于水库、堤防、蓄滞洪区和非工程措施组成的鄱阳湖防洪体系现状,分析了2020年鄱阳湖洪水的雨情、水情和灾情特点,总结了鄱阳湖防洪体系在应对2020年洪水中取得的成效、存在的问题。提出要适应江湖自然节律,学会与洪水共生存,坚持束疏结合、重点防御、人力与技术防汛相结合、工程与非工程措施相结合,实施洪水风险管理,协调好湖泊治理与保护的关系等治水理念。Affected by the continuous heavy rainfall since the end of June,2020 and the flooding of the mainstream of the Yangtze River,the water level of Poyang Lake increased quickly and a super-historical flood occurred.Based on a review of the current situation of the Poyang Lake flood control system,including reservoirs,dikes,flood storage and detention areas,and non-engineering measures,the rainfall regime,water regime,and disaster characteristics of the flood event are analyzed,and the effectiveness and shortcomings of the Poyang Lake flood control system are summarized in this paper.It is suggested that we should adapt to natural rhythms of rivers and lakes,learn to coexist with floods,and coordinate the relationship between lake governance and protection.Some ideas for flood control are also proposed,including defense of key areas,the combinations of restraint and diversion,manpower and technology,as well as engineering and non-engineering measures,and flood risk management.
