黄河水沙调控多目标协同模型构建及应用

Construction and application of a multi-objective collaborative model of water and sediment regulation in the Yellow River

  • 摘要: 为促进黄河流域行洪输沙-生态环境-社会经济三大子系统多维功能协同发挥, 提出黄河水沙调控多目标协同总体架构。基于系统整体耦合协调度构建黄河水沙调控多目标协同模型, 实现了不同来水来沙与工程组合情景下黄河水沙调控目标函数与约束条件灵活选择及权重系数适应性调整。以黄河中游三门峡-小浪底水库群为例, 开展丰平枯典型年水沙优化调控。结果表明: 排沙与发电目标间存在强竞争关系, 生态和发电目标间存在弱竞争关系; 系统整体耦合协调度最高的方案均能达到各目标优质协调, 并倾向于发挥更大发电效益。模型应用结果启发管理者在实际调度中适当提升发电量, 并在枯水年注意增加生态供水。研究成果可为黄河水沙多目标优化调控实践提供科技支撑。

     

    Abstract: To promote the multi-objective coordination of the three subsystems of water and sediment discharge, ecological and environmental, and social and economy in the Yellow River basin, an overall multi-objective collaborative framework of water and sediment regulation for the Yellow River was proposed. The model was constructed based on the overall coupling coordination degree of the system to achieve a flexible selection of objective functions and constraints, as well as an adaptive adjustment of weight coefficients under different water and sediment conditions and various combinations of engineering. Taking the Sanmenxia and Xiaolangdi reservoirs in the middle reaches of the Yellow River as a case study, the optimal water and sediment regulation of high-flow, normal-flow, and low-flow years was carried out. The results reveal that there is a strong competitive relationship between sediment discharge and power generation targets and a weak competitive relationship between ecological and power generation targets. The schemes with the highest coupling coordination degree of the whole system can achieve high-quality coordination of each target and tend to exert greater power generation benefits. The application results of the model can inspire managers to appropriately increase power generation in actual scheduling and pay attention to increasing the ecological water supply in low-flow years. This research can provide scientific and technological support for the practice of multi-objective optimal water and sediment regulation in the Yellow River.
