摘要
为评价海南岛东、南部珊瑚礁生态健康状况,2004年8月对陵水的分界洲岛,三亚的鹿回头湾、榆林湾、蜈支洲岛,琼海的潭门港、龙湾港,文昌的铜鼓岭和长圮港等区域沿岸珊瑚礁进行监测,采用LineIntercept Transect断面法进行调查。通过对造礁石珊瑚种类、覆盖度、死亡率、补充量和发病率等指标分析海南岛东、南部近岸造礁石珊瑚的生态特点。结果表明:海南岛东、南部近岸珊瑚礁发育良好,种类丰富,生物多样性较高。共发现造礁石珊瑚13科32属77种。由于海洋捕捞和海水养殖等人类开发强度加大,该地区近岸部分区域的珊瑚礁生态环境呈退化趋势,珊瑚健康状况受到严重影响。长圮港、潭门港及铜鼓岭珊瑚健康状况较差;三亚鹿回头等区域局部珊瑚生态健康状况良好,生长呈恢复趋势;远离海岸的岛屿区域,如蜈支洲岛和分界洲岛,由于来自陆地的污染和影响小,珊瑚健康状况呈现良好。
In order to evaluate the status of coral reef health,monitoring was carried out with a Line Intercepet Transect method in the areas located in Luhuitou,Yulin bay,Fenjiezhou Island,Tanmen,Longwan,Changpi and Tongguling of the southeast coastal regions of Hainan Island in August,2004.The ecological status of coral reef in the regions were evaluated with the indicators of coral reef species,coverage,mortality rate,recruitment rate and morbidity.The results indicated that the coral were abundant with 77 species and high biodiversity.Due to the influence of anthropogenic,such as marine fishing,marine aquaculture,the ecological environment of the coral reefs was getting deterioration in the regions,and the reef health in parts of the regions was seriously damaged.The reef health in the regions of Tanmen,Changpi and Tongguling was bad,that in Luhuitou was relatively better and it was in a state of recovery.But apart from coastal region,regions such as Wuzhizhou and Fenjiezhou Island,reef health was good due to less impact of land source pollution and tourism activities.
