南方林区TM遥感图象组合方式研究

A Study on Combining Way of the TM Remote Sensing Image of South China Forest Area

就南方林区TM遥感图象的多种组合方式进行了分析、对比，认为TM4、5、3的组合彩色图象（依次分别赋以红、绿、蓝色）及其数据较适用于南方森林植物类型之判读及计算机自动分类；TM472彩色合成图有利于幼林、疏林地、荒山等的判读；

Combinations of TM remote sensing images of South China forest area are analyzed and com pared. The result shows that the TM453 cembination is better for the forest vegetation recognition by visu al interpretation and computer automatic classification. The TM472 color composite image is helpful to the interpretation of young growth, sparse woods and barren mountain. And on the TM472 color-composite image Chinese fir forest can be easily interpreted.
