|Abstract:||The IES-Action GHG-AFOLU aimed to quantifying the effect of land use changes on the overall cycles of greenhouse gases. A major uncertainty for budget estimates is related to the amount of biomass accumulated in above and belowground parts of the forests. In order to made a reliable estimate of these factors it is necessary an enormous amount of manual labor for forest inventories and destructive measurements. In this context, laser scanning seem to be promising and fast method for forest inventories (Holopainen and Kalliovirta, 2006). Moreover cloud point images could be used to create geometric models simulating the three-dimensional architecture of a tree, useful for example to characterize interception of light by dense or sparse canopies or to model the competition for nutrient and water efficiency of root systems (Danjon et al, 1999). The objectives of this research were: - To investigate the suitability of advanced technologies like 3D-Laser scanning to acquire fair and sound information’s on structural and architectural characteristics of poplar stand; - To compare direct and indirect measurement; - To validate geometric models of above- and belowground tree structures using the software’s WGROGRA (Kurth, 1994), AMAPmod v.1.8 (Godin and Guédon, 2001) and JRC-3D-Reconstructor ® (patented by JRC, IPSC, Nuclear Safeguards Unit).|
