摘　　要：利用SPOT影像数据,对研究区进行遥感图像融合处理实验,探讨了基于SPOT影像的水体信息提取的方法,以及在湿地分类中的应用。The utilization of satellite remote sensing and GIS technology for wetland extraction has proven to be an useful application. The objective of this study was to find more efficient way to extract the water body and wetland information from remote sensing data, taking Minjiang river estuary as study area. From SPOT5 images acquired on 14, 12, 2003, the high spatial resolution fusion data was generated. The present wetland information was extracted from this fused image too.

关 键 词：SPOT5影像 影像融合 SFIM方法 湿地分类系统
