摘  要:
本研究是用陆地卫星 TM图象和多元分析方法直接估测森林蓄积量的一次新尝试。其自变量选择了定性和定量因子,所选定性因子是色彩、树种组;定量因子是波段密度值及其比值,较大限度地发挥了遥感资料的潜力。此方法辅以少量地面样地,对有林地蓄积估测精度可达80%以上。是一个简便、易行、经济的方法。

摘  要:
The study is a new attempt that uses Landsat TM image and some ground sampling plots by multi-analysis method to estimate forest stock volume. In this method, independent variables include Qualitative and Quantitative factors. The Qualitative factors are colour hue and group of tree species; theQuantitative factors are density value and ratio of the bands. In this way, potentiality of remote sensing data can be bring into better play.The result shows that the accuracy of estimating forest stock volume is more than 80%, when this method is used. It's a convenient and economical method.The sampling method of ground sampl plots, plot sizes and establish equation according to basins etc. corresponding problem have been discussed in this article.
