摘      要：As one of the main structural units in a building,a solid wood floor has significant strategic research value for low-carbon energy *** the production line of a solid larch wood floor as a case study,we assessed the environmental load during production based upon a life cycle *** GaBi 6.0 software,we analyzed the associated carbon sequestration during floor production,with the initial planting density serving as the disturbance factor in a modular *** results indicated that the cutting and finishing steps have relatively intense,negative influences on the environment,whereas transportation,ripping,and trimming do ***,recycling biomass waste has the potential to reduce greenhouse gas *** the initial planting density was 3.0×3.0 m,carbon sequestration was relatively *** the emissions of freshwater pollutants,volatile organic compounds,and fine particulate matter（matter with a 2.5-μm diameter） were comparatively high,the reduction of greenhouse gas emissions was still excellent at this planting density.
