基于遥感技术，利用TM多光谱影像和SPOT全色影像，在遥感影像处理软件ERDAS8．7中进行几何配准、IHS融合，采用监督分类的方法，对福州市长乐地区的沿海滩涂进行自动提取，并结合地理信息系统软件Arc．GISDeskTop8．3制作滩涂提取专题图。结果表明，遥感技术用于沿海滩涂监测，具有科学性和直观性，是传统方法无法比拟的，能更好地为滩涂管理相关部门的规划和管理提供实时、准确的依据。%Based on RS technique, this paper used TM image and SPOT image, and performed the extraction of beach in Fuzhou coastal area, with geometric matching, IHS fusion and supervised classification process in ERDAS 8.7. Then the thematic map of coastal beach was made in ArcGIS DeskTop 8.3. The result indicates that it is more scientific and more directly to monitoring the coastal beach using the RS technique, which can offer the government real - time and accurate basis for the coastal beach planning, comparing with the traditional methods.
