地理信息技术支撑下的南海岛礁资源环境研究进展与展望

面积辽阔的南海是中国未来重要的能源接续区与资源基地,也是涉及国家海洋权益最为集中的区域。本文针对地理信息技术支撑下的南海岛礁研究现状,从南海岛礁现有基础数据成果、遥感手段岛礁基础地理信息提取方法及提取成果所做的岛礁分析与评价3方面,系统地回顾了国内外涉及南海岛礁资源环境研究的相关进展,评述了现有研究技术方法存在的不足,并对未来的研究进行了展望,在此基础上,提出了3个主要方向作为未来研究的重点：①促进遥感数据获取多源化,构建海量多源、多尺度南海岛礁遥感数据仓库;②加强技术协同创新,结合地理信息技术的发展,提升岛礁信息提取与监测的准确性与可靠性;③提升遥感分析智能化,研究并建立综合分析与情势推演平台及战略决策辅助支撑系统,以期为南海岛礁的进一步深入研究提供参考。

Progress and prospects on coral reefs research in the South China Sea based on the application of geographic information technologies

The South China Sea region is an important prospective energy supply area and a resource base for China. Although coral reef resources are extremely abundant in the South China Sea, research on coral reef data extraction, and analysis and evaluation of coral reef resources have not attracted enough attention. This article put forward an analytical framework based on the application of geographic information technologies in the South China Sea, and reviewed the main progresses in three aspects: current availability of basic geographic data, methods on the extraction of basic geographic information, and evaluation of coral reefs in the Siuth China Sea. Based on the review and analysis, this article proposed three research directions in the future: (1) promote multi-source remote sensing data acquisition, build massive remote sensing databases; (2) strengthen collaborative technological innovation, improve the accuracy and reliability of information extraction and monitoring results; and (3) promote intelligent remote sensing analysis, establish comprehensive analysis and decision-support systems which will provide theoretical reference for the further development of coral reef research in the South China Sea.
