| 摘 要： | 中国北方煤田煤层自燃现象非常严重.利用遥感手段可以快速实现火区的动态监测,及时为灭火工程提供信息.烧变岩作为火区的地表指示性特征,是火区解译最直观的信息.本文从烧变岩的反射光谱曲线特征入手,对几种提取烧变岩信息的方法进行比较,从而确定解译烧变岩的最佳方法,为圈定火区的范围和位置奠定基础. |
| 关 键 词： | 烧变岩 反射光谱曲线 高光谱 信息提取 |

| Abstract: | Spontaneous combustion of coal constitutes a very serious problem in North China. Practice proves that the application of remote sensing technology can achieve rapid dynamic monitoring of coal fire and provide information for the fire-extinguishing project, thus exhibiting great significance. Burnt rocks as the indicators of coal fire at the earth's surface serve as the most visual information for interpreting coal fire. Based on the reflectance curve characteristics of burnt rocks, the authors compared various methods for extracting the information of burnt rocks, and then determined the best method for this purpose, which can help locate and delineate the coal fire. |
| Keywords: | Burnt rock Reflectance spectral curve Hyperspectral Information extraction |
