海岸带地形要素遥感反演技术研究进展

摘要

海岸带地形要素包括海岸线、干出滩地形、浅海水下地形等。以遥感手段获取敏感岸带、争议岸带以及条件恶劣的不可达岸带的地形要素具有天然的优势。阐述了海岸带地形要素遥感反演近年来取得的成果，分析了利用高潮位时相的影像数据提取海岸线、利用低潮位时相的影像数据进行潮滩地形反演以及近岸浅海水深反演等技术的研究进展，并提出了研究建议。%Coastal zone geological features include coastal line ,terrain of dry shoal and the terrain of shallow sea water . Acqusition of geological features of sensitive area ,disputed area and area of abominable conditions with remote sensing meth-od has obvious advantages .Many significant results have been obtained on remote sensing retrieval techniques of geological features .Coastline extracting using remotely sensed image with high water level and tideland terrain retrieval using remotely sensed image with low water level are two basic research aspects .The key technology of coastal line extracting ,tideland ter-rain retrieval and soundings retrieval of shallow sea water are discussed separately and some research directions are put for-w ard .
