摘要
本文根据海岸地貌的成因类型、动力条件和海平面变化等因素,分析涠洲岛海岸地貌的发育;根据涠洲珊瑚礁的沉积环境和海滩岩^(14)C年龄分析,阐明涠洲岛自晚更新世以来处于连续上升状态。
Weizhou Island is a volcanic island, which rocky strata exposed are mainly basalt, tuff and volcanic breccia. The development of morden coastal landform has been effected deeply by hydrodynamics and changes of sea-level. It can be demonstrated by the distribution of coral reef that the south of the island was eroded, and the north, otherwise, piled up. According to the ^(14)C dating, since late Pleistocene, Weizhou Island has been elevated and the average rate is 1.6～2.1mm during the recent 2000～3000 years.
