摘　　要：温室气体(GHG)的排放导致全球气候变暖已成为人类社会的共识。建筑业活动及相关产品产生大量的温室气体,为了定量分析建筑物GHG的排放情况,本文基于生命周期评价(LCA)理论,建立了建筑生命周期碳排放的核算模型。同时,为了探讨建筑业减排指标和减少建筑业碳排放的途径,本文选取木结构、轻钢结构和钢筋混凝土结构3种不同结构形式的建筑,对其生命周期碳排放进行了定量测算和对比分析。结果表明,在满足同样使用功能的前提下,木结构建筑相比其它2种结构的建筑具有较低的生命周期碳排放。The emission of greenhouse gases（GHG） will lead to global warming.A large amount of GHG is generated during the building construction period and relevant materials＇ production period.In this paper,based on the theory of life cycle assessment（LCA）,a carbon emission model was developed to study the building＇s GHG emission.Meanwhile,in order to discuss the carbon emission reduction target and corresponding methods,different structural styles of wood,concrete and steel were selected to carry out the quantitative assessment and comparative analysis.The results shown that the carbon emission of per functional unit（1 m2 building annually） from wood structure building was lower than other structures.
