摘　　要：研究依托国家标准《建筑碳排放计算标准》GB/T51366-2019,对七栋现代木结构建筑的全寿命期碳排放进行计算。研究结果显示,在建筑全寿命周期内,建筑在运行阶段碳排放占建筑全寿命期碳排放比例较大,为82.8%-95.4%。由于木材的使用,减少了传统建材的使用量。如果与仅使用钢筋和混凝土的基准建筑相比,从全寿命期的角度来看,木材的使用可节省8.6%-13.7%的二氧化碳排放。Based on the national standard of GB/T51366-2019, carbon emissions of seven modem wooden structures were calculated. Results show that during the whole life span of the building, carbon emissions in the operation stage accounts for a larger proportion of the carbon emissions of the whole life cycle of the building, which is 82.8%- 95.4%. Due to the use of wood, traditional building materials usage is reduced. Compared with the standard buildings using only steel and concrete, using wood can save &6% to 13.7% of carbon dioxide emissions from the point of view of the whole life cycle.
