摘要:本研究利用1992年成像的覆盖山东省烟台地区的ERS-1SAR和TM资料开展工作。研究中首先将这两种遥感资料进行了几何精纠正和与地形图的配准,尔后,用典型相关分析法对遥感资料(ERS-1SAR、TM3、TM4和TM7)与森林参数(包括平均树高、胸径、枝下高、冠层厚度和郁闭度)间进行了相关分析研究,结果表明,C波段的ERS-1SAR资料与森林冠层厚度和平均树高相关程度较高;森林参数综合因子对ERS-1SAR影像的影响大于对所用TM波段的影响,说明ERS-1SAR资料在森林应用中,对森林参数乃至于森林蓄积量的估测是有潜力的。
The data sets used for this study were obtained over the Yantai region inShandong
Province by ERS一1 SAR and TM during the period of 1992.Those remote sens-ing data were
geometrically corrected and digitally registered.The relationship betweenERS一1SAR,TM data
and forest parameters was analysed by using the method of canonicalcorrelation analysis. The
results showed that there was a close correlation between C一bandof ERS一1SAR data and
crown thickness and average tree height,which indicated that theinfluence of various forest
parameters on ERS 1SAR image was bigger than that on TMimage. So there is a great
potential of applying ERS一1SAR data for estimating forest pa-rameters,even forest volume.
