摘　　要：为提供一种适合轻型木结构建筑碳排放计算方式及降碳路径,采用全生命周期分析方法,将轻型木结构建筑生命周期分为木材固碳、建筑建材的生产与运输、建筑施工、运行使用、拆除处理五个阶段,通过研究各个阶段的碳排放计算,得出符合轻型木结构建筑特点的全生命周期碳排放计算方法,并提出合理选择建筑木材、延长木材储碳周期、优化能源消耗结构、科学管理工程施工等降碳策略,以期为轻型木结构建筑全生命周期碳排放计算提供方法指导,为轻型木结构建筑选材、建设、运行及拆除处理等阶段相关方案优化提供参考依据。To provide a suitable light timber structure building on calculation of carbon emissions and carbon reduction paths,the whole life cycle analysis method was used in this paper,the light timber structure life cycle was divided into five stages,including wood carbon production,building materials and transportation,construction,operation use and demolition process.According to the research on various stages of the carbon calculation,a whole life cycle carbon emission calculation method was obtained in line with the characteristics of light timber structure buildings,and carbon reduction strategies were put forward,such as rational selection of building wood,extension of wood carbon storage cycle,optimization of energy consumption structure,scientific management of engineering construction.It is expected to provide method guidance for the calculation of carbon emissions in the whole life cycle of light timber structure buildings,and provided reference for the optimization of relevant schemes in the stages of material selection,construction,operation and demolition treatment of light timber structure buildings.
