| 摘 要： | 利用森林火灾后的TM影像 ,应用最佳波段监督分类法、第三主成分分量 (PC3)滤波阈值法和IHS变换法对罗源县境内的历年森林火灾信息进行提取 .通过对比发现最佳波段监督分类法和PC3滤波阈值法的森林火灾信息提取精度较高 ,而IHS变化法效果较差 .同时还分析了影响精度的原因 ,提出利用地形、地理特征来提高火烧迹地信息提取精度的观点 .

| Abstract: | The three methods of best-band classification,filtered-PC3 threshold, and Intensity-Hue-Saturation (IHS) transformation have been applied to extracting information about the forest burnt areas in Luoyuan County using the post-fire TM image. The extraction results using the three methods are compared and it is found that the first two methods are better than the latter. The reasons for the different extraction results using the methods are also discussed in this study. Finally,the view that the application of the geo-spatial characteristic of burnt scar can improve the extraction accuracy is presented. |
