摘要
对佳蓬列岛造礁石珊瑚调查得知,该区域造礁石珊瑚有8科16种,以霜鹿角珊瑚、盾形陀螺珊瑚、粗糙刺叶珊瑚、十字牡丹珊瑚和扁缩滨珊瑚为优势种,造礁石珊瑚平均线形概率为48.2%,以水坑湾和大凼湾最高,分别达80%和71%;其垂直分带明显,密集分布的水深为5～15m。佳蓬列岛珊瑚礁资源已过度开发和人为破坏严重,死的造礁石珊瑚覆盖率为7.1%,文中并提出保护珊瑚的措施。
The community and structure of hermatypic corals was surveyed from Jiapeng Islands in October 2004. The results showed the hermatypic corals were 16 species among 8 families, and the dominate species were Acropora pruinosa （Brook）, Turbinaria peltata （ Esper）, Echinophyllia aspera （ Ellis ＆ Solander） , Pavona clecussate （Dana） and Porites compressa （Dana） . The average line probability of hermatypic corals was 48. 2%. The high density sites located within small bays. The spatial distribution presented vertical zone obviously, it mainly distributed in depth of 5 - 15m. The average line probability of killed hermatypic corals was 7. 1%. The resources of coral reef have overexploited and seriously destroyed in this area, the protection measures were also put forward in the paper.
