摘要: 利用内蒙古大兴安岭北部4个林业局生长季和非生长季获取的Landsat-5 TM影像,对影像进行大气校正、几何校正、镶嵌和裁剪等预处理,通过统计分析准差、相关系数和OIF指数,对两期不同时相影像的最佳波段组合进行分析。结果表明:研究区TM影像生长季的最佳波段组合是345和234,非生长季的最佳波段组合是245,345和234。研究结果可为进一步应用TM影像进行森林资源信息提取提供参考。

关键词: 时相, TM影像, 最佳波段组合

Abstract: Landsat-5 TM images of growing seasons and non-growing seasons for four forestry bureaux in northern Daxing'anling mountains of Inner Mongolia were used.Preprocessing of images including atmospheric correction,geometric correction,mosaic and cutting was conducted. Such jobs were also done as the statistical analysis of standard deviation,correlation coefficient and OIF index,analysis of the best band combination of two different date images.The results show that the best band combination of the study area TM images for the growing season is 345 and 234,the best band combination of non-growing season is 245,345 and 234.The results can be applied to use of TM images for forest resources information extraction.

Key words: date, TM image, the best band combination
