原始语种摘要: Abstract(#br)Tree root biomass contributes significantly to forest carbon pools but is difficult and costly to estimate. Accurate estimates of carbon fluxes from tree roots are required for specific mitigation projects, national accounts and global climate models. However, methodologies for the estimation of tree root biomass are varied and their effectiveness in terms of the precision of biomass and carbon estimates is difficult to evaluate. In this study tree root systems of 2 and 7year old Eucalyptus globulus (Labill) trees were sampled volumetrically to a depth of 6m using soil coring and excavation. These root mass data were used for Monte Carlo simulation of four different but typically used sampling strategies.(#br)The uncertainty of estimates...
