| 摘 要： | 飞雁滩海域是1964－1976年黄河刁口河流路入海区域。根据地形和断面水深监测资料，阐述了该岸段流路废弃后的岸滩侵蚀特征和地貌变化。研究结果表明，刁口河流路废弃后飞雁滩海岸向海凸出的地形特征，是造成该岸段强烈侵蚀的重要原因。进一步结合波、流动力的对应分析认为，波浪以掀沙为主，潮流以输沙为主，波浪和潮流的联合作用是飞雁滩海岸侵蚀的主要动力机制，其中潮流主要通过余流携沙外榆，造成近岸泥沙亏损。

| Abstract: | Feiyantan was the discharge area of Diaokou Channel of the Yellow River during the period from 1964 to 1976. The coastal erosion feature and morphological evolution at the Feiyantan coast are studied from the topography and section depth, together with corresponding dynamics of wave and current. Resuits indicate that the protruding topography left when the Diaokou Channel was abandoned is the main cause of strong coastal erosion. Further research suggests that waves stir sediments and tidal currents transport the sediments, and waves and tidal current are combined into the dominant dynamic mechanism of coastal erosion, of which tidal residual current takes and transports sediment outward, thus it causes sediment to wane in the coast. |
