摘　　要：水库预报调度是水库防洪调度的重要方式之一,能够提高水库流域洪涝灾害防御能力。创造新蓄水纪录的密云水库长期处于中高水位运行与水库下游河道行洪能力受限都增加了水库洪涝灾害防御压力。为有效解决水库上下游“蓄、泄”两难的实际问题,通过分析密云水库运行情况、洪水预报开展情况、水库上下游淹没影响范围、预报调度实例等内容,得出基于分布式水文模型EasyDHM的密云水库洪水预报系统能够很好地适应密云水库流域洪水模拟,同时洪水预报结果能够很好地支撑水库预泄调度。Reservoir operation based on forecasting is one of the important ways of flood operation of reservoir and can improve the flood prevention ability of reservoir basin.Miyun Reservoir,which has set a new water storage record,will operate at a medium and high water level for a long time and the flood discharge capacity of the downstream river of the reservoir is limited,which increases the flood defense pressure of the reservoir.In order to effectively solve the dilemma of"storage and discharge"in the upstream and downstream of the reservoir,this paper analyzes the operation of the Miyun Reservoir,the development of flood forecasting,the impact range of flooding in the upper and lower reaches of the reservoir,and the example of operation based on forecasting.It is concluded that the flood forecast system of Miyun Reservoir based on the distributed hydrological model EasyDHM can well adapt to the flood simulation in the basin of Miyun Reservoir.The flood forecast results can support the pre-discharge operation of reservoir well.
