一、前言渤海湾西北部淤泥质海岸南起海河北至南堡,岸线长约75公里。1983年5月—9月和1984年6月,对该段海岸进行了岸滩动力地貌调查,其中一级剖面2条,二级剖面7条,84年重复测量剖面4条,三级剖面11条,采取潮滩表层沉积物样品80个,柱状样11个,初步获得了一些动力地貌资料。由于该项工作仅在夏季进行,岸滩特征又随季节海洋动力因素的不同而异,
I. Foreword The silt coast in the northwest of Bohai Bay starts from the north to the south of the coast of Haihe River. The coastline is about 75 km long. From May to September 1983 and June 1984, a coastal dynamic geomorphological survey was conducted on this section of the coast, of which there are two first-level sections, two second-level sections, four 84-year repeated measurement sections and three-level sections 11 Article, 80 tidal flat sediment samples and 11 columnar samples were taken and some dynamic geomorphological data were obtained. Since this work is only carried out in summer, the characteristics of shore beaches vary with the seasons of the ocean dynamic factors,
