%X 中国城镇住宅在建筑材料的生产、运输和施工过程中带来严重的环境影响,该文综合运用生命周期评价和情景分析方法,基于eBalance数据库平台,研究了中国城镇住宅的物化环境影响。结果表明: 2010年中国城镇住宅的物化环境影响约占中国15.5%、 15.2%、 39.2%、 4.1%、 15.9%和17.5%的能源消耗、用水量、化学需氧量、氨氮、二氧化硫和氮氧化物排放量,且主要来自建筑材料的生产阶段,尤其是钢材和水泥的生产,二者之和约占全部建筑材料生产阶段环境影响的70%, 其中钢材占55%。因此,从环境保护的视角考虑中国城镇住宅发展的调控具有重要意义。<br>Abstract： Building material production, transportation, and building construction of urban residential buildings all impact the environment in China. The eBalance software was used to calculate the embodied environmental impact of urban residential buildings in China using the life cycle assessment (LCA) method and scenario analyses. The results show that the embodied environmental impact of urban residential buildings in China accounted for 15.5% of the national total energy use, 15.2% of the water use, 39.2% of the COD emissions, 4.1% of the NH3-N emissions, 15.9% of the SO2 emissions, and 17.5% of the NOx emissions in 2010. The impacts were mainly due to the manufacturing of the building materials, especially the steel and cement which accounted for 70% of all the buildings materials with steel itself being 55%. Therefore, it is vital for regulating the urban residential buildings based on the perspective of environmental protection.
