我国海岸带及其近海资源环境监测的遥感技术应用

Remote Sensing Application to Monitoring Resources and Environment in China's Coastal Zone and Near-by Ocean

海岸带及其近海自身丰富的自然资源和优越的地理位置是国家经济发展的重要区域。如何利用多源、多通道、多时相、主被动融合的星载遥感数据获取海岸带及其近海资源环境信息是遥感应用技术的重要任务之一。本文依据国内外环境遥感应用技术的研究与发展,归纳了我们在我国海岸带及其近海资源环境遥感信息研究及其在国家有关工程计划中的应用,包括海岸带典型地物信息提取、淤泥质潮滩水边线信息提取、淤泥质潮滩冲淤变化、悬浮泥沙信息提取、内波信息提取。

The coastal zone and its near-by ocean have been of importance for economic development due to their rich natural resources and specific geographic location. How to qualitatively and quantitatively retrieve the environment information in these areas from multi-sensor, multi-channel, multi-temporal and both active and passive satellite-borne remote sensing becomes a key issue for remote sensing application. Based on the advancement of current development of remote sensing technology, this paper briefly presents the progress of our research on information retrieval for China＇s costal zone and its near-by ocean, and applications in some state engineering projects, such as classification of typical canopies and surface objects of the costal zone, spatial distributions of the tidal flat waterside lines, the deposition and erosion in silt tidal fiat, and the suspended sediments and internal waves.
