A NEW STUDY ON ESTIMATING FOREST STOCK VOLUME USING SPACE REMOTE SENSING DATA

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; the Quantitative 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.
