摘要
利用生命周期评价方法,建立了我国化石能源的生命周期清单模型,详述了模型相关因子的确定方法,计算了原煤、原油、天然气等初级能源及汽油、焦炭等几类主要次级能源的生命周期清单,揭示了我国能源生产的环境负荷,为工业系统分析和材料、产品的生命周期评价提供基础数据.清单分析表明我国化石能源清单的主要特点为能源消耗的97%以上主要来自生产过程,运输占到3%左右的比例;通过与2002年清单相比,我国化石能源生产的总能耗和排放出现不同程度变化;通过与国外能源清单相比,我国能源投入及排放整体处于较高水平.
This paper makes the life cycle inveritory analysis of fossil energy in China by implementing the calculation model in context of such primary energy as coal, oil and natural gas, as well as second energy like petrol oil, coke. It will be helpful to identify the environmental performance of energy production in China and to make a life cycle assessment of other industrial processes and products. The inventory analysis shows that 97% of energy consumption in China is contributed by industrial process, only 3% by transportation. Based on the comparison of the results of referenced literature in 2002, it shows that the inventory of China＇s fossil energy varies to some extent. The fossil energy input and environmental emissions from energy production is higher than that of advanced countries.
