本研究对南海北方岸礁珊瑚群落的现状及其在维持海南岛东北部（海南湾铺前湾）海岸线稳定中的潜在作用进行了评价。录得39个珊瑚品种，平均覆盖率为5.3%，以大型Galaxea，Platygyra和Porites为主。珊瑚群落分为两个组（Clu-HNB和Clu-PQB），对应于不同的稳定的海岸条件。海南湾的珊瑚群落多样性较高，覆盖度较大，海岸线相对稳定;而浦前湾南部的珊瑚群落多样性和覆盖度最低，海岸线侵蚀严重。这项工作提供了一些直接证据，证明珊瑚礁的衰退会削弱其维持海岸线稳定的功能，导致严重的海岸侵蚀。这也有助于帮助沿海管理人员和当地人民更加重视珊瑚礁在沿海保护中的重要性，并鼓励他们改变方式，以实现珊瑚礁资源的可持续利用。这可能是有益的启发或启动海岸工程管理海岸与天然珊瑚礁解决方案。
This study evaluated the status of coral communities at the fringing reefs in the northern South China Sea, and their potential role in maintaining nearby coastline stability of northeastern Hainan Island (Puqian Bay, Hainan Bay). Thirty-nine coral species were recorded with mean coral cover of 5.3%, and are dominated by massive Galaxea, Platygyra and Porites. The coral communities were clustered into two groups (Clu-HNB and Clu-PQB) corresponding to different stable coastal conditions. Coral communities at the Hainan Bay with higher diversity and greater cover corresponded to relatively stable coastline, whereas those at the southern Puqian Bay (with the lowest coral diversity and spatial coverage) corresponded to severe coastline erosion. This work provides some direct evidence that declined coral reefs would weaken their functions to maintain a stable coastline, resulting in severe coastal erosion. It is also useful to help coastal managers and local people pay more attention to the importance of coral reefs in coastal protection and encourage them to change their ways to get sustainable use of coral reef resources. It may be beneficial to inspire or initiate coastal engineering to manage coasts with natural coral reef solution.
