平潭岛岚湖沉积环境和成因的研究

在中全新世后阶段，当海岸风沙正处于始发状态，平潭西南的岗湖还是一个由多叉的山谷组成的洼地。到全新世晚期，由于全球气候的变化和优势的北北东方向风力的逐渐增强，河谷洼地与海湾相联结的地区长时间风沙的堆积而形成岚湖。

Study on the Sedimentary Environment and Origin of Lanhu Lake in Pingtan Island

he paper focuses on the discussion of sedimentary environment and origin of Lanhu Lake in Pingtan Island. In the late sarge of Middle Holocene, the coastal eolian action in Pingtan Island was in an initial stage and Lanhu Lake on the southwestern part of Pingtan Island was a depression consisting of polyforked valleys. Due to the change of the global climate and gradually strengthened predominant NNE wind in Late Holocene, the eolian sand had been accumulated for a long time in the area between the valley depression and the bay, and Lanhu Lake was formed.
