摘　　要：依据2018年地形资料,分析了地面沉降对大陆泽、宁晋泊蓄滞洪区滞洪容积的影响。采用Mike21软件,建立了该片区域的二维水力学模型,按照现有的洪水调度规则,对50年一遇设计洪水、“63·8”校核洪水进行了模拟。根据洪水模拟成果,提出大陆泽、宁晋泊蓄滞洪区的调整方案,为该蓄滞洪区的运用提供技术支撑。Based on the 2018 topographic data,the influence of land subsidence on the flood storage volume of the Daluze and Ningjinbo areas is analyzed.Using Mike21 software,a two-dimensional hydraulics model of this area was established.According to the existing flood scheduling rules,50-year design flood and"63·8"checked flood were simulated.According to the flood simulation results,the adjustment plan of the flood storage and detention areas was put forward,and suggestions were put forward for the application of the local flood storage and detention areas.
