摘　　要：目前,我国甜高粱、木薯等"非粮"燃料乙醇正处于规模化推广的前期论证阶段,亟需对其进行全面深入的可行性分析。文章基于生命周期评价原理,结合国内4家燃料乙醇生产企业的示范工程,对其全生命周期过程的能源消耗、环境影响和经济成本提供定量的评价结果,为评价、对比"非粮"乙醇和"粮食基"乙醇提供科学、权威的数据,填补了这一方面国内研究领域的空白。评价结果表明,发展甜高粱和木薯等非粮乙醇是可行的,与玉米乙醇相比具有较强的优势。At present, ＂non-food＂ fuel ethanol including sweet sorghum, cassava and other energy crops is at the early stage of large-scale demonstration phase, and it is urgently needed to conduct a comprehensive and in-depth feasibility analysis. Based on the principle of life cycle assessment, this study analyzes the whole processes of energy consumption, environmental impact and economic costs for china＇s four ethanol demonstration projects, and provide quantitative evaluation results. The results will provide scientific and authoritative information for comparing ＂non-grain＂ and ＂food-based＂ ethanol and fill the gaps in the field of domestic research. Evaluation results show that the development of sweet sorghum and cassava, and other non-grain ethanol is feasible, and ＂non-grain＂ has a strong advantage by comparison with corn ethanol.
