摘　　要：以浙江省台州市三门县为例,运用SPOT5不同空间分辨率的融合影像进行土地利用类型调查及面积遥感调查,通过对数据进行选择与预处理工作,利用ERDAS IMAGINE 8.4图像处理软件,对遥感影像进行配准、几何精纠正、融合等,在对研究区土地利用类型的分类中,采用人机交互判读方式,并提出一套适宜高分辨率遥感影像土地利用分类的技术路线。SPOT5 images with different spatial resolutions, which are processed using fusion technique, is applied to investigate and analyze the land utilization status of Sanmen County in Zhejiang Province. Before land use classification and further analysis, ERDAS IMAGINE 8.4, software for image processing and analyzing, is used in image pre-processing, such as geo-correction, co-registration and fusion. Then, land use classification is carried out through image interactive interpretation technology; meanwhile, a practical technology roadmap is outlined in this paper for land use classification with high spatial resolution optical images.
