摘要

摘要: 山东荣成市成山头南侧发育了一条沙坝和一系列的湖,组成成山卫湖链,以面积最大的天鹅湖有关资料为主,运用粒度分析、软体动物鉴定、¹⁴C测年等方法,对So5,Sh5,Sh1和Sh6孔岩心进行分析,揭示了该湖链的形成过程:距今7000a左右,海水开始入侵,形成了荣成湾,距今6000a左右,沙坝和坝内的一系列半封闭湖形成.根据沙坝层理的观测资料分析了湖形成后自然作用下的演化动态,并指出近年来由于人类活动加剧,严重影响了湖的演化过程.

Abstract: There are a piece of bar and a series of lagoon in Chenshantou,Rongcheng City,Shandong Peninsula,which consist of Chengshanwei bar-lagoon chain.Based on analysis of lithological features,mollusca,and ¹⁴C,the sedimentary facies,formation and evolution of Chengshanwei lagoon chain in Shandong Peninsula are studied by taking the materials of the Swan Lake as the main data.The analysis results of Cores So5,Sh1,Sh5,Sh6 in the area show that at about 7 000 a BP,sea water intruded this area and formed the Rongcheng Bay,and at about 6 000 a BP the series of half-closed lagoon appeared inside the bar.Under the observation of bar-bedding,the evolution dynamics can be analyzed after lagoon was formed.But because of the serious human activities,the human factors also impact on the process of lagoon evolution.
