摘要:
南海珊瑚岛礁远离大陆且面积较小，高分辨率遥感技术已成为大范围进行珊瑚岛礁监测的重要手段，而建立适用的遥感分类体系和解译标志是进行珊瑚岛礁遥感监测的基础。本文综合考虑珊瑚岛礁的形成机制、珊瑚礁形态和高分辨率遥感影像上珊瑚岛礁图斑的可解译程度等因素，制定应用于珊瑚岛礁高分遥感监测的分类体系，将珊瑚岛礁分为珊瑚岛、沙洲、干出珊瑚礁、珊瑚暗礁、珊瑚暗沙和珊瑚暗滩6个一级类型；并在现场调查数据的辅助下，从遥感影像上的色、形、位等特征方面建立珊瑚岛礁不同类型的遥感解译标志，结果可服务于南海珊瑚岛礁的动态监测，进而为珊瑚岛礁的保护、可持续利用和安全管理提供数据支撑。

Abstract:
The coral islands and reefs in the South China Sea are far from the mainland with a relatively small area; thus, the high-resolution remote-sensing technology has become an important tool for monitoring them on a large scale. The basis of remote-sensing monitoring of coral islands and reefs is to establish a suitable remote-sensing classification system with interpretation marks. The formation mechanism of coral islands and reefs, coral reefs morphology, and interpretable degree of coral islands and reef patches on high-resolution remote-sensing images were all considered in this study. The classification system for the high-resolution remote-sensing monitoring of coral islands and reefs was formulated and established the interpretation marks of coral islands and reefs using the field survey data. This can serve the dynamic monitoring of coral islands and reefs in the South China Sea by providing data support for the protection, sustainable utilization, and security management of coral islands and reefs.
