摘　　要：地表覆盖变化信息提取更加依赖丰富、准确、可靠的多时相、多层次、多分辨率、多源的数据,因此,为了获取地表覆盖的信息,必须要对影像波段进行优化组合。不同的波段组合对不同的地图显示的效果不同,多光谱影像合成需要进行波段组合优化,本文重点针对地表覆盖研究中经常采用的TM的多光谱数据的波段选择问题,对地表覆盖研究具有借鉴意义。Land cover change information extraction more dependent on the rich, accurate and reliable for a long time relative to multi - level multi - resolution multi - source data, in order to obtain the land cover information, must be the image - band to optimize the combination. Different band combinations the effect of different map display, multi - spectral image synthesis requires the band combi- natorial optimization, the paper focuses on land cover band of TM, which are frequently used in the research and application of multi - spectral data, land applied research to be learned.
