摘　　要：利用生命周期评价理论,对E10、E22、E85和E100等木薯乙醇—汽油混合燃料进行了生命周期能源、环境及经济性评价,并提出木薯乙醇—汽油混合燃料推广可行度指标。结果表明:与汽油比较,所有木薯乙醇—汽油混合燃料生命周期的整体能源消耗增加,石油消耗降低;生命周期CO、CO2和HC排放降低;生命周期成本增加,并需要政府补贴政策支持。从平衡能源消耗、环境影响和经济性角度考虑,E10是较合适的推广应用形式。Life cycle energy, environment, and economic assessment were carried out for comparing the energy consumption, environmental impacts, and economy of different cassavabased ethanol blended gasoline fuels including E10, E22, E85 and E100. And the promotion viability indictor of these cassavabased ethanol blended gasoline fuels was put forward. Compared with gasoline, all cassavabased ethanol blended gasoline fuels achieve more life cycle total energy consumption, less petroleum consumption, lower life cycle CO, CO2, and HC emissions, higher life cycle cost, and need government subsidy. Form the viewpoint of balancing energy, environment, and economy, E10 is a betterimplemented form.
