摘要
山东半岛北部海岸为岬湾式海岸,这里砂坝-潟湖广泛分布,形成本区海岸最重要的地貌景观。本区从湖间带至沿岸平原,从表层至地下,组成了一个形成于不同时代的砂坝-潟湖群。本区全新世后期的砂坝-潟湖的发育与演变,导致岸线向海推进。因此岸线的演变与砂坝-潟湖的发育有着密切的联系。从本区砂坝-潟湖的研究可知,自大西洋期以后,特别是距今4345a(^(14)C测年)以来,随着砂坝-潟湖的不断形成和衰亡及并陆,使陆域扩大,岸线不断向海移动。
The coast of the northern part of the Shandong peninsula is of a cape-bay type. There the wide distribution of sand bars and lagoons forms the most important geomorphic landscape of the coast in this area.In the area from the intertidal zone to the coastal plain and from the surface to underground there appeared a group of sand bars and lagoons which had been formed in different epochs.The development of the sand bars and lagoons in this area at the late Holocene epoch led to the seaward progradation of the coast line. Therefore the evolution of the coast line is closely related to the development of sand bars and lagoons. From the study of the sand bars and lagoons in this area it can be seen that after the Atlantic, especially in the past 4345 years, the continous formation and decline of the development of the sand bars and lagoons and their incorporation with land expanded the land area and moved the coast line continuously seawards.
