海南岛周边海域造礁石珊瑚的群落结构及其分布

基于形态学分类鉴定,并辅以分子标记,我们于2014–2015年调查分析了海南岛文昌云龙湾、万宁大洲岛、儋州磷枪石岛、昌江沙鱼塘村、三亚鹿回头海域造礁石珊瑚的种类组成和分布。结果表明,海南造礁石珊瑚的分布较为广泛,共鉴定出10科17属55种,其中鹿角珊瑚科、滨珊瑚科和蜂巢珊瑚科为优势科。各海域造礁石珊瑚的群落结构不同：南部三亚鹿回头海域以分枝状鹿角珊瑚为主,东部文昌云龙湾和万宁大洲岛海域分别以叶片状和分枝状蔷薇珊瑚为主,而西部儋州磷枪石岛和昌江沙鱼塘村则分别以团块状滨珊瑚和蜂巢珊瑚为主。不同的地理环境使海南岛周边海域珊瑚礁群落呈现出不同的演替型,具有明显的地域性分布特点。5个不同海域造礁石珊瑚的...

Summary:基于形态学分类鉴定,并辅以分子标记,我们于2014–2015年调查分析了海南岛文昌云龙湾、万宁大洲岛、儋州磷枪石岛、昌江沙鱼塘村、三亚鹿回头海域造礁石珊瑚的种类组成和分布。结果表明,海南造礁石珊瑚的分布较为广泛,共鉴定出10科17属55种,其中鹿角珊瑚科、滨珊瑚科和蜂巢珊瑚科为优势科。各海域造礁石珊瑚的群落结构不同：南部三亚鹿回头海域以分枝状鹿角珊瑚为主,东部文昌云龙湾和万宁大洲岛海域分别以叶片状和分枝状蔷薇珊瑚为主,而西部儋州磷枪石岛和昌江沙鱼塘村则分别以团块状滨珊瑚和蜂巢珊瑚为主。不同的地理环境使海南岛周边海域珊瑚礁群落呈现出不同的演替型,具有明显的地域性分布特点。5个不同海域造礁石珊瑚的覆盖率和多样性指数依次为：三亚鹿回头〉文昌云龙湾〉昌江沙鱼塘村〉万宁大洲岛〉儋州磷枪石岛,覆盖率和多样性指数具有明显的正相关性。与2005–2010年的调查结果相比,文昌云龙湾和万宁大洲岛保护区造礁石珊瑚的覆盖率和多样性指数有所上升,昌江沙鱼塘村和三亚鹿回头相对稳定,儋州磷枪石岛则下降比较明显。死亡率较高的是昌江沙鱼塘村邻近海域,且多为最近半年内死亡。人类活动（保护性或破坏性）极大地影响着造礁石珊瑚的多样性、覆盖率和死亡率。
Bibliography:Based on the classical morphological and molecular taxonomy, 55 scleractinian coral species, belonging to 17 genera and 10 families, were recorded in five different coastal areas（Yunlong Bay, Wenchang; Dazhou Island, Wanning; Linqiangshi Island, Danzhou; Shayutang Village, Changjiang; Luhuitou, Sanya） of Hainan between 2014 and 2015. The dominant families included Acroporidae, Poritadae and Faviidae. The community structures of coral reefs in the five coastal areas were different. In Sanya, located in the south of Hainan, branching Acropora corals dominated the coral communities. In Wenchang and Wanning, on the eastern coast of Hainan, the laminar and branching Montipora corals were the dominant groups. In contrast, the mass corals Poritadae and Faviidae dominated the western coast in Danzhou and Changjiang. Analyses of community structure indicated that different geographic environments regulated successional differences. Coverage rates and diversity index values had a positive correlation and were as follow
