海南岛西北部海域珊瑚群落健康状况评价
Assessment of Coral Reef Ecosystem in Northwestern Sea Area of Hainan Island
摘要
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 communi-ties 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 com-munities 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.关键词
