采用实测资料分析和理论探讨相结合的方法,揭示了黄河口尾闾河道萎缩过程,探索了河道萎缩与水沙条件的响应关系。结果表明,尾闾河道萎缩过程与水沙条件有着良好的响应关系,小浪底水库实施调水调沙明显改善了水沙条件,河道萎缩有所恢复,为科学治理黄河口提供了技术支撑。 The method of combining the measured data analysis and theoretical exploration is used to reveal the atrophy process of the Yellow River estuary and the relationship between the river shrinkage and the water and sediment conditions. The results show that there is a good response between the atrophy process of the tail channel and the water and sediment conditions. The implementation of water and sediment adjustment in Xiaolangdi Reservoir has obviously improved the water and sediment conditions, and the atrophy of the river channel has recovered, providing technical support for the scientific management of the Yellow River estuary.
