摘　　要：采用TM影像与中巴卫星遥感图像作为主要数据源,以野外实地调查、航空像片和地形图等资料为辅,基于ERDAS IMAGINE和ENVI等遥感软件作为处理平台,运用最佳波段组合、图像校正、图像增强、神经网络图像分类等先进的遥感数据处理手段,实现对苏州市城市绿地信息的充分提取,得到1986、1998、2004年苏州市绿化覆盖情况的动态调查结果。并从苏州市整体和局部等多角度讨论绿化分布和变化状况,最后分析和评价了苏州市绿地格局分布的特点。The city greenbelt information of Suzhou is extracted by the following means： adopting TM images and the China Brazil Earth Resources Satellite （CBERS-1） data and using advanced remote sensing image processing means such as band combination, image rectification, image enhancement, neural network classification, with the aids of the field survey, airphoto and relief map, ERDAS IMAGINE and ENVI software. On the basis of these processing means, the author obtained the dynamic investigation result of the greenbelt overlay in 1986, 1998 and 2004. Finally, the paper discusses the greenbelt distributing and the changing situation through multiple analyses of these results wholly and locally, and summarizes the characteristics of the greenbelt pattern distribution of Suzhou.
