| 摘 要： | 为优化黄河中下游水库群运行方式，充分发挥水库群-河道联合调控水沙的优势和潜力，以黄河中下游水库群和河道为研究对象，研究水库群-河道水沙联合动态调控方法，构建水库群-河道水沙联合动态调控互馈指标、互馈模式、调控原则和调控方式，研发水库群-河道水沙联合动态调控模拟模型，分析黄河中下游现状工程调控效果。结果表明，未来黄河来沙量8亿~3亿t情景下，水库群-河道水沙联合动态调控方法综合兼顾水库和河道减淤，可延长水库拦沙年限4~9 a，在较长时期内改善进入下游的水沙关系协调度，下游河道总淤积量较少，河槽最小平滩流量增大200~250 m3/s。

| Abstract: | In order to optimize the operation mode of reservoir groups in the Middle and Lower of the Yellow River, and to give full play to the advantages and potential of the water-sediment joint regulation of reservoir groups and river channel, taking the reservoir groups and river channel in the Middle and Lower of the Yellow River as the research objects, the method of joint dynamic regulation of reservoir groups and river channel was studied, and the mutual feedback index, mutual feedback model, regulation principle and application of joint dynamic regulation of reservoir groups and river channel were constructed. In this way, we developed a water-sediment joint regulation simulation model of reservoir groups and river channel, and analyzed regulation effects of the current project in the Middle and Lower of the Yellow River. The results show that under the scenario of 800 million to 300 million tons of incoming sediment of the Yellow River in the future, the water-sediment joint dynamic regulation of reservoir groups and river channel comprehensively takes into account the reduction of siltation in the reservoir and the river course, and can extend the sediment retention period of the reservoir by 4 to 9 years. In a relatively long period of time, the coordination degree of the water-sediment relationship entering the downstream has been improved. The total siltation of the downstream river channel is less, and the minimum bank-full discharge of the river channel has increased by 200—250 m3/s. |
