珠江口万山群岛珊瑚生态多样性调查

Coral ecological diversity survey of Wanshan Islands in the the Pearl River Estuary

珊瑚对人类的意义绝不仅仅只是一个旅游景点,事实上它对维持全球生物多样性、维持渔业资源、保护海岸线、优化大气环境有着重要作用。然而当前珠海市珊瑚生态多样性调查结果比较零散,调查数据也比较陈旧,不能完全反映现状。通过2020、2021年对珠江口万山群岛造礁石珊瑚群落结构和分布的调查,本研究在万山海域共记录鉴定石珊瑚13科25属69种,高于历史文献数据,通过对比2012、2020年珠江口造礁石珊瑚群落的调查结果,掌握了珠江口万山群岛造礁石珊瑚群落生物多样性的现状。同时本研究讨论了珠江口万山群岛造礁石珊瑚群落面临的生存威胁和亟待加强保护的迫切需要,提出珠江口万山群岛造礁石珊瑚群落保护和管理的建议。

The significance of coral to humans is not just a tourist attraction.In fact,they play an important role in maintaining global biodiversity,maintaining fishery resources,protecting coastlines,and optimizing the atmospheric environment.However,the current surveys of coral ecological diversity in Zhuhai are scattered,and the survey data is relatively old,which cannot fully reflect the current situation.Through the investigation and research on the structure and distribution of reef coral community in Wanshan Islands,the Pearl River Estuary,in 2020 and 2021,69 species of reef coral belonging to 25 genera,13 families,were recorded and identified in Wanshan Sea Area,which is higher than the historical literature data.By comparing the investigation results of reef coral community in the Pearl River Estuary in 2012 and 2020,the status of biodiversity of reef coral community in Wanshan Islands,the Pearl River Estuary was mastered.At the same time,the survival threats faced by the reef coral community in the Wanshan Islands of the the Pearl River Estuary and the urgent need to strengthen protection were discussed,and suggestions for the protection and management of the reef coral community in the Wanshan Islands of the the Pearl River Estuary were put forward.
