Plain lakes are crucial water sources for regional development, but increasing hydrological changes and intensified human activities have exacerbated conflicts among their functions. This study focuses on Hongze Lake, significantly impacted by the South-to-North Water Diversion East Line Project, which elevated water levels and substantially altered regional water resource utilization, while flood management regulations have remained unchanged. To investigate the impact of adjusting flood limit water level on various functions of Hongze Lake, a multi-objective optimal scheduling model for water resources was developed, encompassing water supply, water diversion, navigation, and ecological conservation. This model was combined with a projection pursuit optimization model to solve the scheduling scheme set.

粗放型平原湖水资源多目标优化调度，包括洪水资源利用


平原湖泊是区域发展的重要水源，但日益严重的水文变化和加剧的人类活动加剧了其功能之间的冲突。本研究重点关注洪泽湖，该湖受到南水北调东线项目的严重影响，该项目提高了水位并显着改变了区域水资源利用率，而洪水管理法规保持不变。为探究调洪限水位对洪泽湖各项功能的影响，建立了包括供水、引水、航海、生态涵养在内的多目标水资源最优调度模型。该模型与投影追踪优化模型相结合，求解调度方案集。
