Quantitative Structure Modeling of Excavated Stump-Root Systems from Terrestrial Laser Scanning Point Clouds: Formulation and Destructive Validation in Pinus taeda
Belowground biomass (BGB) is an important component of forest carbon stocks but remains poorly quantified owing to the difficulty of measuring it directly. This study evaluated terrestrial laser scanning (TLS) combined with quantitative structure models (QSM) to estimate root volume, biomass and carbon in Pinus taeda....
