| 摘要: |
| 为明确海南岛西北部海域珊瑚群落的健康状况，本研究在儋州市、临高县所辖海域布设16个调查站位，系统监测该海域底质类型组成以及活珊瑚(硬珊瑚、软珊瑚)、死珊瑚、大型藻类和其他生物群落的覆盖率，并基于此计算珊瑚群落健康指数，进而对珊瑚群落健康状况进行综合评价。结果表明，研究海域底质以礁石为主(平均覆盖率为64.0%)，砂质为辅(平均覆盖率为29.0%)，活珊瑚呈斑块状分布(平均覆盖率为7.0%)，软珊瑚与死珊瑚在研究区域的覆盖率均为0.0%；大型藻类覆盖率为1.0%—55.0%，平均覆盖率为14.5%，空间分布差异显著；其他生物群落覆盖率整体处于低水平，覆盖率为0.4%—2.6%，平均覆盖率为0.7%；珊瑚群落健康状况分化明显，其中2个站位为“非常好”、2个站位为“很好”、4个站位为“一般”、3个站位为“很差”、5个站位为“非常差”。总体而言，海南岛西北部海域珊瑚群落整体健康状况不佳，多数站位处于较差水平，大型藻类局部高覆盖率与活珊瑚分布不均是其主要特征。研究结果可为该区域珊瑚群落的保护修复与可持续管理提供科学依据。 |

| Abstract: |
| To clarify the health status of coral communities in the northwestern sea area of Hainan Island,this study set up 16 survey stations in the sea areas under the jurisdiction of Danzhou City and Lingao County.We systematically monitored the composition of substrate types,as well as the coverage of living corals (hard corals and soft corals),dead corals,macroalgae and other biological communities in the sea area.Based on this,the condition index of coral communities was calculated,and then the health status of coral communities was comprehensively evaluated.The results showed that the substrate in the study area were dominated by reefs (with an average coverage of 64.0%),supplemented by sandy substrate (with an average coverage of 29.0%).Live corals were distributed in patches (with an average coverage of 7.0%),and the coverage of soft corals and dead corals in the study area was 0.0%.The coverage of macroalgae was 1.0%—55.0%,with an average coverage of 14.5%,showing significant spatial variation.The coverage of other biological communities was at a low level,ranging from 0.4% to 2.6%,with an average coverage of 0.7%.Coral community health status showed significant differentiation.Among all stations,2 were rated as “excellent”,2 as “very good”,4 as “moderate”,3 as “poor”,and 5 as “very poor”.In general,the overall health status of coral communities in the northwestern sea area of Hainan Island is not good,and most stations are at a poor level.The high coverage of macroalgae and the uneven distribution of live corals are the main characteristics.The results of this study can provide a scientific basis for the conservation,restoration and sustainable management of coral communities in this region. |
