| 摘 要： | 阐述了K—T变换的原理及其在植被信息提取方面的优点。将基于K—T变换提取的NDVI结果与直接在TM影像上提取的NDVI结果进行比较。实验结果表明，基于K—T变换的NDVI提取方法得到的结果图像纹理清晰、光谱保持能力强，对于区域植被覆盖信息提取，进而对生态环境变化、荒漠化等研究具有较重要的意义。

| Abstract: | This paper describes the principle of K - T transformation and the advantages of K - T transformation in extracting vegetation information. In order to test the result,NDVl based on K - T transformation compare with NDVI based on TM images. The experiment shows that the images of this method of extracting NDV1 can get distinct texture and better light spectrum property. For the regional vegetation cover information extraction, and then study the ecological environment change, desertification, and other research has more important significance. |
