珊瑚礁的地貌过程是地球仪变化海岸带陆海相互作用研究的主要内容之一。雷州半岛西南部是琼州海峡与北部湾的交汇处。拥有中国大陆独特的典型发育和保存完好的海岸珊瑚礁。由于沉积物来源和动力条件的差异，东西两岸海岸地貌发育有珊瑚礁地貌、火山熔岩地貌、海蚀地貌和人工地貌等。本文详细研究了它们的地貌特征和分布规律。通过对珊瑚礁的地貌过程分析，发现珊瑚礁地貌与海平面变化、构造沉降、地震活动之间存在一定的相关性。认为全新世气候和海平面的变化是控制该区珊瑚礁地貌发育的主要因素。
：The biogeomorphological process of coral reefs is one of the major contents in the studies of land-ocean interaction in the coastal zone of the globe change. The southwestern Leizhou Peninsula is a juncture of Qiongzhou Strait and Beibu Gulf. It has unique typically developed and well preserved coastal coral reefs of the mainland of China. Due to the differences of sediment sources and dynamic conditions, there have developed different coastal landforms on the east and west banks, including coral reef geomorphy, volcano lava geomorphy, marine abrasion geomorphy and man-made geomorphy, ect. Their geomorphical characters and distributions are studied in details in this paper. By analysing the biogeomorphologicl process of coral reefs, the correlations between coral reef geomorphy and sea-level changes, tectonic subsidence, seismic activities of the studied area are discovered. We conclude that the changes of climate and sea-level of Holocene are the main factors that control the coral reef geomorphical developments in the area.
