摘　　要：以福建省永安市两乡镇的林业小班图层为基础,利用"资源二号"影像与TM影像的融合,有效地增强了不同林地之间的差异和林地之间的界线;并利用1996年林相小班图层,通过属性选择提取不同林地小班专题,转换成感兴趣区域(AOI)。以AOI限制分类范围对融合图像进行分层监督分类,直接得到不同林地的动态变化区域,从而减小林相图更新的工作量。On the basis of forest patches coverage layers of 2 townships of Yongan City, Hujian, the integration of Image resource II and Image TM effectively enhances the differences and boundaries between diverse forestland. According to the forest form map layers of patches coverage in the year of 1996, different thematic patches coverage obtained from attribute selection has been transformed into Area of Interest (AOI). That the integrated image has been stratified, supervised and classified in the limited range by AOI leads to the dynamic changing area of different forestland. This method greatly reduces the labor demanding for renewal of forest form map.
