| 摘 要： | 文章通过断面法调查分析了儋州海域海花岛沿岸、南华墟沿岸和磷枪石岛沿岸造礁石珊瑚的种类组成与群落分布，结果表明：儋州海域造礁石珊瑚共有12科25属55种，相较于此前的研究增加了10个种，优势种为斯氏角孔珊瑚、澄黄滨珊瑚、柱角孔珊瑚；活造礁石珊瑚覆盖率急剧下降，由2012年的42.92%下降至现在的22.24%，降幅高至48.18%；造礁石珊瑚死亡率高居不下，长期维持在35%左右；初级群落以团块状造礁石珊瑚为优势种的趋势愈发明显，且单一绝对优势种的情况频繁出现，说明该海域造礁石珊瑚群落受到了较为严重的破坏，导致群落退化演替，分析认为这种破坏是由自然因素和人为活动共同造成的。

| Abstract: | The species composition and community distribution of scleractinia coral along the coast of Haihua Island,Nanhuaxu Island and Linqiangshi Island in Danzhou sea area were investigated and analyzed by cross-section method.The results showed that there were 55 species of scleractinia coral in 25 genera,12 families in Danzhou sea area,10 species more than the previous studies,and the dominant species were Goniopora stutchburyi,Porites lutea,Goniopora columna.The coverage rate of living scleractinia coral dropped sharply,from 42.92% (2012) to 22.24% (now),with a drop rate as high as 48.18%;the mortality rate of scleractinia coral remained high,around 35% for a long time;the trend of dominant species in primary community was block scleractinia coral,and the situation of single absolute dominant species appeared frequently,which indicated that the scleractinia coral community in the sea area had been seriously damaged.It is believed that the degradation succession of the community was caused by both natural factors and human activities. |
