佳蓬列岛造礁石珊瑚的群落结构研究

Study of community and structure of hermatypic corals in Jiapeng Islands

  • 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5~15 m。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。

     

    Abstract: 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 decussate (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.
