| 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。

| Abstract: | The data sets used for this study were obtained over the Yantai region in Shandong Province by ERS-1 SAR and TM during the period of 1992.Those remote sensing data were geometrically corrected and digitally registered.The relationship between ERS-1 SAR,TM data and forest parameters was analysed by using the method of canonical correlation analysis.The results showed that there was a close correlation between C-bandb of ERS-1 SAR data and crown thickness and average tree height,which indicated that the influence of various forest parameters on ERS-1 SAR image was bigger than that on TM image.So there is a great potential of applying ERS-1 SAR data for estimating forest parameters,even forest volume. |
