| 摘要: |
| 本研究对三亚珊瑚礁保护区的珊瑚礁生态系统健康状况进行了评估,采用珊瑚健康指数(Condition Index, CI)作为评价工具,通过2024年6月在保护区海域内布设的20个调查站位所收集的数据,分析了珊瑚种类、造礁石珊瑚覆盖率、珊瑚死亡和病害情况、珊瑚补充量等关键指标。结果显示,保护区整体珊瑚礁生态系统健康状况良好,造礁石珊瑚平均覆盖率为18.25%,CI指数平均值为1.664,处于健康水平。东西瑁洲海区、鹿回头-榆林角海区和亚龙湾海区的CI指数平均值和珊瑚补充量表现出一定的区域差异,这种差异可能与各海区的环境条件和人类活动强度的不同有关。本研究为三亚珊瑚礁保护区的保护管理和评价提供了科学依据,也为其他珊瑚礁保护区的生态健康评估提供了参考。 |

| Abstract: |
| This study evaluated the health status of coral reef ecosystems within the Sanya Coral Reef Reserve using the Coral Condition Index (CI) as the assessment tool. Data collected in June 2024 from 20 survey stations deployed throughout the reserve were analyzed for key indicators including coral species composition, hard-coral cover, coral mortality and disease, and coral recruitment. The results indicate that the overall coral reef ecosystem of the reserve is in good health: mean hard-coral cover is 18.25 % and the mean CI is 1.664, both falling within the healthy range. Regional differences in mean CI and coral recruitment were observed among the East-West Maozhou, Luhuitou–Yulin Cape, and Yalong Bay sectors, likely reflecting variations in local environmental conditions and human-activity intensity. The findings provide a scientific basis for the conservation management and assessment of the Sanya Coral Reef Reserve and offer a reference for ecological health evaluations of other coral reef protected areas. |
