海南三亚湾海岸地貌与沉积环境研究进展

Research Progress on Coastal Geomorphology and Sedimentary Environment of Sanya Bay in Hainan

摘要: 三亚湾现代海岸绝大部份位于宽平的海岸大沙坝上，是激浪活跃的砂质堆积海岸：湾的两端是海蚀的基岩岸，且不同程度地分布着珊瑚礁。在整体上，三亚湾为一大型的较开阔的港湾海岸，波浪作用为主，但在某些岸段潮流作用与生物活动亦为活跃的因素。所以，三亚湾海岸地貌类型丰富。本文拟对三亚湾海岸作简单剖析，对沉积动力与海岸地貌的形成进行初步讨论。

Abstract: The modern Sanya Bay coast is most located in the wide Dashaba coast, and is Sandy accumulation coast by Active wave: both ends of the bay are the bedrock coastal because marine-abrasion. And the coral reefs are distributed in different degrees. As a whole, as the wave action, Sanya Bay is a large open embayed coast. But the tidal current and biological activities are also active in some coastal areas. Therefore, Sanya Bay coastal landform types are abundant. This paper intends to make a simple analysis of the coastal Sanya Bay, and preliminary discussion on the formation of sedimentary dynamics and coastal geomorphology.
