海南岛地跨北纬18°16′至20°18′,属热带—亚热带气候,常年平均气温为24℃左右,年温差小于10℃。沿岸断断续续地分布着一些岸(裾)礁,附近各小岛的周围和个别较大的泻湖中也局部地分布有珊瑚礁和活珊瑚。 海南岛沿岸的珊瑚礁,马廷英、颜京松、以及和颜京松、黄明显等,都作过一些研究。但上述作者都从生物学的角度出发,研究了海南岛近岸珊瑚的种属及其分布,很少或者完全没有论及本区珊瑚礁的地质学和地貌学的基本问题。 Hainan Island across the latitude 18 ° 16 ’to 20 ° 18’, a tropical - subtropical climate, perennial average temperature of about 24 ℃, annual temperature difference of less than 10 ℃. There are intermittent shore 裾 reefs along the coast, with coral reefs and live corals also distributed locally around the smaller islands and in the larger lagoons. Coral reefs along the coast of Hainan Island, Matting Ying, Yen Chung-song, and Yan Jing-song, Huang Ming-hsien, have done some research. However, the above authors studied the species and distribution of coral nearshore in Hainan Island from a biological point of view, with little or no reference to the basic problems of geology and geomorphology of coral reefs in this area.
