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.

Key words: South China Sea, coral reefs, geographic information technology, resources and environment, progress and prospects
