摘　　要： 在我国城市化进程加速与基础设施大规模建设的社会发展背景下,研究建筑物化能消耗量及其所导致的大气污染物排放量。从全社会经济活动的角度出发,以建筑生命期为主线,建立并运行经济投入-产出生命期评价模型,比较和分析建筑物化能的来源与组成,量化主要大气污染物的排放。此外,对建筑物化能与大气影响进行预测分析,并为建筑节能减排工作提出对策与建议。研究结果表明:建筑物化能约占我国社会总能耗量的16%,因此对其研究不可忽视;各类能源在消耗过程中所释放的有害气体,是我国大气环境的重要污染源;若继续2002年的产业关联状况水平,2015年我国建筑物化能及其大气污染物在全社会总能源消耗和污染物排放中的比重将持续上升。研究成果丰富了全生命周期评价模型在我国建筑领域的应用,完善当前的相关统计数据,为我国广义建筑能耗与环境影响问题提供计算方法和数据支持,同时也为政府主管部门制定相关政策提供理论参考与依据。 With the background of rapid urbanization and large-scale infrastructure constructions in China,the embodied energy and atmosphere impacts of construction projects are analyzed by adopting the Economic Input-output Life-cycle Assessment Model.The sources and components of building embodied energy are illustrated and the amount of related environmental emissions is calculated.A prediction is conducted,and a series of strategies and suggestions are provided for energy conservation and atmosphere pollutant reduction in China.Results show that building embodied energy accounts for nearly 16% in total social energy consumption in 2007,and should not be excluded from the system of building energy efficiency.Emissions occurring in the energy embodying process are the main polluters of the country＇s atmosphere,and the proportion of building embodied energy and relevant emissions in the entire society will be increased in 2015 if keeping 2002＇s industry correlation level,which indicates that effective regulations and measures are indispensable.

关 键 词： 建筑物化能 大气影响 投入 产出生命期评价 节能减排
