非三角洲泥沙质海岸可分为发育有沿岸堤的沿海平原和障壁岛一泻湖两个基本类型。长期以来，渤海湾西岸全新世贝壳堤被归入前一范畴，我们则认为其初始阶段可能是介于二者之间的、在较小动能条件下形成于潮间带的线性沙坝。其根据简述如下。经校核的24个地点的83个14C数据（包括 The non-deltaic silt coasts can be divided into two basic types: the coastal plain with coastal embankments and barrier island-lagoon. For a long time, the Holocene shell embankment in the west coast of the Bohai Bay has been classified into the former category. However, we believe that the initial stage may be a linear sand dam formed in the intertidal zone with little kinetic energy. It is summarized as follows. 83 14C data for the 24 locations reviewed (including
