摘　　要：运用生命周期评价(Life Cycle Assessment,即LCA)方法,以广州市生活垃圾的不同处理方式为研究对象,对卫生填埋、焚烧处理和综合处理方式进行了较为系统的生命周期评价。通过目标和范围的确定,对每种处理方式的各个子过程进行了生命周期清单分析及环境影响潜值的计算,结果表明:卫生填埋、焚烧处理和综合处理方式的环境影响潜值分别为5.24×10-2人当量、4.85×10-2人当量和1.68×10-2人当量,综合处理方式明显优于另两种方式。最后根据清单分析及环境影响评价,对每种处理方式的缺点进行了分析并提出建议。In order to study different treatments of house refuse in Guangzhou, the sanitary land- fill, the incineration and the comprehensive treatment have been studied comprehensively by the method of LCA. Through the confirmation of the goat and scope,the inventory analyze and and environment impact potential calculation were made to subprocedure of each treatment. The result shows that the potential environment impact of sanitary landfill, incineration and comprehensive treatment is 5.24×10-2 equivalent man , 4.85 ×10-2 equivalent man and 1.68×10-2 equivalent man,and the comprehensive treatment is obviously better than others. Finally, According to life cycle in- ventory and environment impact assessment, the analyzes and suggestions were made to the disadvantages of each treatment.
