摘　　要：以生命周期理论为基础,建立木结构与其他建筑结构材料的碳排放算法模型,量化分析不同建材的碳排放量。结果表明:木结构材料的碳排放明显少于钢结构和混凝土结构材料;四个树种的木结构材料中,东北落叶松的碳排放最小,为68 tCO_2:北美冷杉的碳排放最大,为1 175 t CO_2。合理选择木材树种及产地,将进一步降低木结构建筑的碳排放。Based on life cycle analyses theory, the authors established an algorithm model for calculating carbon emissions from structural building materials used in timber construction and other constructions. The authors then quantitatively analyzed the carbon emissions from the relevant structural materials.The results showed that carbon emissions from timber construction were significantly less than that from steel and concrete. Moreover, carbon emissions from wood varied with different wood species. Among the four species selected for the timber construction, Larix gmelinii. timber released minimum carbon emissions with 68 tons of carbon dioxide, and Abies grandis timber released the maximum carbon emissions with 1 175 tons of carbon dioxide.
