摘　　要：对TM遥感图像各原始及常用比值波段的信息量大小、相互间存在的多重相关性及其对郁闭度估测造成的不利影响进行分析研究。针对特定监测区域,对设置的遥感比值波段,采用平均残差平方和准则进行筛选,最终确定对郁闭度估测有一定影响的遥感波段,并形成可操作的软件系统。In order to defining the remote sensing factors influencing forest canopy density effectively,based on the research of predecessors, the magnitude of information on each wave bands and ratio wave bands in common use of TM remote sensing image,the muhi-collinearity existed between each other and its unfavorable influence to the estimation of canopy density were studied and analyzed in this paper. To certain monitoring area and the remote sensing ratio wave bands defined, by means of the criterion of mean residual sum of squares to carry on filtering of remote sensing factors, finally the important remote sensing wave bands influencing canopy density estimation are confirmed, meanwhile the operable software system is programmed.

关 键 词：遥感比值波段 方差扩大因子 信息量 多重相关性
