摘　　要：以长江口崇明东滩为研究区,在分析崇明东滩典型地物的反射光谱特性和散射特性的基础上,对ERS-2 SAR数据和Landsat ETM+数据分别进行了处理,其中对ERS-2 SAR数据进行了小波去噪处理和纹理特征信息的提取,对ETM+数据进行了HIS彩色空间变换,然后在特征级层次上对两者进行了信息融合,最后对融合后的图像进行了典型地物信息的提取,并且根据我们野外实地调查数据和已有的研究成果,对本文的分类结果进行了评价,取得了满意的效果。Based on analysis of the reflection spectrum and backscattering characteristics of typical land canopies, the Chongming eastern tidal flat of Yangtze River Estuary, as a typical case, is chosen for study of data fusion from ERS-2 SAR and Landsat ETM ＋ observations. The ERS-2 SAR data are firstly filtered by the wavelet method and extraction of the image texture. The Landsat ETM ＋ data is treated using the HIS transformation. Two images are fused on the level of the characteristics class, and the information extraction and classification of the typical land canopies are discussed. The results are well validated by the ground truth from the field survey.
