Abstract
Based on the field survey data, this paper has analyzed the capability of Radarsat-SAR data on extracting the forest stock volume. The results obtained show that the Radarsat-SAR backscatter coefficient has a relatively good correlation with the forest stock volume, tree height and diameter at the breast height. Studies also show that the backscatter coefficient is much more affected by height than by diameter at the breast height. It is held that C band of SAR can be used to extract forest stem volume in a large plantation but is not suitable for forest survey.
