摘　　要：1976年黄河改道从水清沟入海后,黄河三角洲前沿桩106至黄河海港岸段的海底地形遭受强烈侵蚀,岸滩不断蚀退。黄河三角洲强侵蚀岸段岸线监测资料与历史资料分析研究结果表明,1985-2004年该区最大侵蚀深度达7.5 m,其强侵蚀区中心位置经历了由西北向东南移动的过程,范围不断缩小,目前局部地区已发生淤积现象。种种迹象表明,从冲淤并存和以侵蚀为主向冲淤平衡过渡的现象还将长期进行下去。Since the diversion of the Yellow River in 1976, the submarine topography in the Yellow River delta coastal zone Pile 106 to Yellow River Port has suffered intensive erosion, and the shore has constantly retrograded. It is shown from the analysis results of available shoreline monitoring data and historical observed data that the maxium erosion depth in the area during 1985 to 9.004 has reached 7.5 m, the central location of intensive erosional area has undergone a shifting process from northwest to southeast, the scope of intensive erosional area has decreased constantly, and the silting phenomena have occurred in some local areas. There are indications that the transitional phenomenon from the period of erosion being dominant to the regime period will continue for a long time.
