The invention relates to the field of river basin flood control scheduling, and particularly relates to a river basin flood control scheduling scheme emulation system. The river basin flood control scheduling scheme emulation system comprises a basic data collection system, a real-time water-rainfall information collection system, a data processing system, a scheduling scheme receiving system, a data inquiry display system, a scheduling scheme retrieving-selecting unit, and a scheduling scheme emulation system, wherein the basic data collection system, the real-time water-rainfall information collection system, the data processing system, the scheduling scheme receiving system, the data inquiry display system, the scheduling scheme retrieving-selecting unit, and the scheduling scheme emulation system are respectively connected with a data storage unit. According to the river basin flood control scheduling scheme emulation system provided by the invention, for a river basin, the visualized emulation and simulation can be carried out on a flood control scheduling scheme via reservoir flood regulating calculation and riverway flood evolution calculation according to set flood control project application parameters in the river basin flood control scheduling scheme selected by a user, the storage-discharge process of each reservoir in the river basin and the dynamic evolution process of flood in a river basin system can be reflected, and the efficiency of a flood control scheduling decision is improved.
