涠洲岛海蚀地貌特征及其海蚀痕迹的地质意义

Geomorphological Characteristics of Sea Erosion and Geological Significance of Sea Erosion Marks on Weizhou Island

涠洲岛是我国最大最年轻的第四纪火山岛,受多期次海进、海退及波浪和构造作用的共同影响,岛上海蚀阶地、海蚀崖、海蚀残丘、海蚀穴、海蚀窗、海蚀桥、海蚀沟、海蚀柱等海蚀地貌发育具有极高的景观价值。海蚀地貌中遗留的海蚀痕迹能表征海平面变化、区域构造运动、地质岩性特征等多种地质意义,亦具有较高的科研价值。

Weizhou Island is the largest and youngest Quaternary volcanic island in China,which is influenced by multiple times of transgression,regression,wave and tectonic process.The roles of sea erosion terrace,cliff,monadnock,cave,window,bridge,trench,stack and other sea erosion landscape development on the island have high landscape value.Sea erosion in the traces left by sea can indicate a variety of sea level changes in the geological sense,regional tectonics,geological lithology,which also has a high scientific value.
