| 水库汛期运行水位协同浮动旨在不增加防洪风险前提下，挖掘中小洪水利用潜力，提升流域水资源利用水平和供水保障能力，已成为防洪与水资源高效利用领域的研究热点和难点。从防洪库容置换与风险防控出发，基于动态预见期和预泄能力约束，嵌套运用预泄预蓄法和库容补偿法，解析了梯级水库汛期运行水位协同浮动关系；考虑帕累托最优解集和最优前沿的动态变化特性，建立了面向动态多目标的梯级水库汛期运行水位协同浮动调度模型；把环境变化检测、随机再生种群和基于参考点的帕累托前沿预测策略引入智能算法，提出求解调度模型的动态多目标智能算法，基于风险效益评价指标以评估调度方案，为梯级水库汛期运行水位协同浮动运用提供技术支撑。 |

| Synergetic control of reservoir flood operating water levels is aimed at developing the potential of small-medium flood magnitudes，meanwhile improving water resources efficiency and water supply security of a river basin without increasing flood risk.Such synergetic control is becoming one of the research hotspots and fronts in flood control operation and efficient use of water resources.The three-fold scheme in this paper was executed step by step：(1) from the perspectives of flood capacity reallocation and risk prevention，integrating reservoir storage complementarity and the pre-refilling and pre-releasing method by considering dynamic forecast horizons and pre-releasing capacity constraints to analyze the synergetic relationship of flood operating water levels of cascade reservoirs;(2) establishing a synergetic control model of flood operating water levels of cascade reservoirs for meeting dynamic multi-objective needs by considering dynamic changing characteristics in the Pareto optimal set and optimal front;and (3) fusing environmental change detection，randomly re-generated population and reference point-based prediction strategy of the Pareto front into the intelligent algorithm to develop a dynamic multi-objective intelligence algorithm for optimizing the synergetic control model，meanwhile applying risk-benefit evaluation indicators to assess operation solutions and providing technical support for achieving synergetic control of flood operating water levels of cascade reservoirs. |
