摘要
应用卫星TM数据 ,通过石漠化波谱曲线分析 ,选择样区进行校正、监督分类、矢量化和数据转换 ,实现石漠化图斑的计算机解译。研究表明 ,利用卫星遥感技术开展石漠化调查是一种可行的方法 ,不仅周期短 。
Using TM satellite data, the authors analyzed spectral curve features, chose the region of interest for supervising classification, vectorization and data conversion, and finally realized automatic interpretation of the rocky desertification spots on computer. This study indicates that the application of remote sensing technique to investigating rocky desertification is an effective means, which is characterized not only by short period but also by great accuracy.
