摘　　要：珊瑚礁作为海洋中典型的生态系统具有重要的意义。我国沿岸珊瑚礁分布面积存在较大争议,受限于技术方法和近岸水体透明度及珊瑚礁分布特征,近岸珊瑚礁分布状况调查主要采用人工潜水的方式开展,缺乏高效的调查设备和技术方法。本文针对这一现状,研究开发了一种便携式的珊瑚礁分布调查系统,并选择广西涠洲岛进行试点应用。该调查系统可实现水下影像资料和GPS位置信号同步,并配合甲板单元实现数据的实时分站记录和存储。研究调查显示,该调查系统操作可操作性强且安全高效,可大幅提高调查作业效率至150%~200%。试点调查结果与涠洲岛珊瑚礁分布历史调查数据基本吻合,调查误差仅3.8%。As a typical ecosystem in the ocean,coral reef ecosystem is of great significance.There is a big dispute over the distribution area of coastal coral reefs in China.Due to the limitation of technical methods,the transparency of coastal waters and the distribution characteristics of coral reefs,the survey on the distribution of coastal coral reefs is mainly carried out by artificial diving,and there is a lack of efficient survey equipment and technical methods.In this paper,a portable coral reef distribution survey system was developed and applied in Weizhou island of Guangxi.The survey system can realize the synchronization of underwater image data and GPS position signal,and realize real-time sub-station recording and storage of data with deck unit.The investigation shows that the investigation system is operable,safe and efficient,and can greatly improve the investigation efficiency to 150%~200%.The results of the pilot survey are basically consistent with the historical survey data of reef distribution in Weizhou island,and the error is only 3.8%.
