南海资源环境地理研究综述

A review of geographical information research on resources and environment of the South China Sea region

南海及沿岸地带是亚太地区经济发展最有活力和潜力的地区之一,受全球变化和人类活动的影响,南海资源环境正发生快速变化,对社会、经济、生态和环境带来新压力。本文从地理空间信息角度,以海岸资源、海洋资源和珊瑚礁资源的地理研究为综述内容,梳理了该区域岸线遥感监测、油气资源储量及渔业资源渔获量的地理差异、珊瑚礁地貌遥感监测与珊瑚白化等相关研究进展,讨论了已有研究的成果及其薄弱方向,依据发展趋势探讨了未来研究工作的重点。综述发现,南海资源环境的地理空间研究中,主要成果表现在资源环境的大面积快速监测与地理分异性方面,但在资源分布的内在机制及资源开发的环境效应影响方面仍缺少足够的研究。未来可望获得突破的研究主要包括:区域时空多尺度特征及其效应,区域间自然和社会发展的分异和规律,多源数据融合的南海资源动态监测的精度与时效的提高,以及资源变化过程的海洋生态与环境综合效应研究等。

The South China Sea and its coastal zone are one of the most active and high potential areas for economic development in the Asia-Pacific region. Affected by global changes and human activities, the resources and environment in the South China Sea region were changing drastically, imposing new pressures on the society, economy, ecology and environment. This article reviewed related geographical research of coast zone, marine and coral reef resources from the perspective of geospatial information. It examined various current works of remote sensing monitoring on the shoreline, the geographical difference analysis of oil-gas reserves and fishery catch, and remote sensing monitoring on coral reef landform and coral bleaching. this article also discussed the existing research results and shortcomings and analyzed the possible focus of future research based on development trends. The results show that the geospatial research on resources and environment of the South China Sea had made many achievements in the large scale rapid monitoring and geographical differentiation of resources so far. Meanwhile, research on the internal mechanism of resource distribution, as well as the environmental impact of resource development, is insufficient. Studies that can be expected to achieve breakthroughs in the future include: multi-scale analysis of spatiotemporal feature of the region and their effects,differentiation and pattern analysis of inter-regional natural and social development, improvement of dynamic monitoring accuracy and timeliness of the South China Sea resources based on the integration multiple-source data,and the comprehensive effects of marine ecology and environment in the process of resource change.
