中文摘要：
在中国基于镁生产的实践，环境影响的量的评估根据生命周期评价(LCA ) 的理论和框架被执行学习。包括 CO2， SO2， NOx， CH4， HF 和微粒的主要气体的污染物质是计算的。不同精力的积聚的环境表演使用策略和描述结果，包括不能生活的弄空潜力(自动数据处理) ，全球温暖潜力(GWP ) ，使发酸潜力(AP ) 和人毒性的潜力(HTP ) 被比较。结果证明在这个过程的燃料燃烧的直接排放是到镁生产的污染物质排放的主要贡献者。全球温暖潜力和使发酸潜力做主要贡献到积聚的环境影响。在镁生产的实践的不同燃料使用策略在环境表演上引起大部分不同影响。直接烧的煤的积聚的环境影响最高，并且制片人气体的来到下一个，当焦炭炉气体的最低时。
英文摘要：
Based on the practice of magnesium production in China, a quantitative evaluation of the environment impact was carried out according to the theory and fi＇amework of life cycle assessment（LCA） study. The major gaseous pollutants including CO2, SO2, NO/, CH4, HF and particulates were calculated. The accumulative environmental performances of different energy use strategies and the characterization results, including abiotic depletion potential（ADP）, global warming potential（GWP）, acidification potential（AP） and human-toxicity potential（HTP） were compared. The results show that the direct emission of fuel combustion in the process is the major contributor to the pollutants emission of magnesium production. Global warming potential and acidification potential make the main contribution to the accumulative environmental impact. The different fuel use strategies in the practice of magnesium production cause much different impacts on the environmental performance. The accumulative environmental impact of coal burned directly is the highest, and that of producer-gas comes to the next, while that of coke-oven gas is the lowest.
