使用TM遥感影像,借助GIS软件进行了影像的处理和解译;制作了植被类型图,计算主要植被类型的面积及其变化情况;分析了3S技术在植被调查中的优势,并调查了植被动态变化,为植被恢复模式的建立提供了依据.%Based on the data available and using the GIS software, we processed and interpreted the Remote Sensing images composed by TM. And we also made the vegetation type chart, in order to calculate the vegetation type area and its change. In this thesis, we explored the advantages of 3S techniques in vegetation investigation and found the dynamic changes in vegetation type area, so as to lay the foundation for building vegetation restoration mode.
