    黄河口海岸冲淤演变的影响因素

    FACTORS CONTROLLING OVER THE COAST SCOURING AND DEPOSITION AT YELLOW RIVER ESTUARY

    • 摘要: 采用实测资料分析,对黄河口口门附近海岸冲淤演变的影响因素进行了研究,结果表明:黄河口口门附近海岸为淤泥质海岸,是在河流动力与海洋动力的共同作用下形成的;影响黄河口海岸带冲淤演变的主要因素是黄河入海水沙量和海洋动力;此外,海平面相对升降、地形地貌特征、地质特征、植被情况、人类活动等因素也对海岸冲淤演变有着明显的影响。黄河口海岸的冲淤演变影响因素的研究对于河口治理有重要的实际指导意义,科学调控黄河入海水沙过程,可以有效控制黄河口海岸淤积延伸,巧妙利用黄河口海洋动力作用,可将淤积在河口口门附近的泥沙经过多次搬运,均匀地分布在更广泛的海域。

       

      Abstract: The factors influencing coastal scouring and deposition pattern at the Yellow River Estuary was studied based on existing data. The muddy coast around the Yellow River Estuary was the result of river-sea interaction. The main factors which influenced the coastal evolution of the Yellow River Estuary include the flow and sediment charges from the river and its interaction with marine dynamics. In addition, factors, such as sea level fluctuation, geo-morphological and geological features, vegetation and human activities, are also important to the coastal evolution of the Yellow River Estuary.The study of the influencing factors of scouring and deposition is critical to the management of the Estuary.Through rationale regulating the incoming flow and sediment of the River,there is possibility to control the scouring and depositional pattern along the coast at the River Estuary.Marine processes,which could bring sediment away from the River mouth to be re-depositde in the offshore area,should also be fully considered.
