摘　　要：生命周期影响评价是生命周期评价的重要环节。生命周期影响评价根据清单分析所提供的物质、能源消耗数据及各种排放数据,对系统或产品的环境影响进行评价。提出能量的使用、不可再生资源消耗、人体毒性、气溶胶、酸化和全球变暖6个重要的燃料影响评价指标。建立评价指标的优化模型,以木薯乙醇混合燃料的全球变暖潜力(GWP)指标为例,进行优化案例分析。生命周期影响评价指标和优化方法可用于各种燃料的影响评价和优化,具有重要的应用价值。Lifecycle effects evaluation, as a significant step in lifecycle evaluation, referred to the evaluation of the effects of a system or a product on the environment by means of the known substances, resource consumption data and discharge data. Six important fuel lifecycle effects evaluation indexes were put forward in this paper including the use of energy, the consumption of non-renewable resources, human toxicity, aerosol, acidification and global warmup. Besides, the optimization models of the evaluation indexes were established and an example of the GWP （global warmup potentiality） index of cassava-ethanol composite fuel was given as case analysis. Lifecycle effects evaluation indexes and its optimization methods which was of high use value could also be applied in the effects evaluation and the optimization for other kind of fuel. （Tran. by YUE Yank）
