摘　　要：基于生命周期评价(Life Cycle Assessment,LCA)的原则与理论框架,针对重庆市主城区某生活垃圾卫生填埋场的收运及填埋阶段进行系统的LCA评价。通过目标和范围确定、选取适合重庆市的环境影响因子进行清单分析和环境影响潜值计算。评价结果表明生活垃圾卫生填埋过程中光化学臭氧合成贡献了最大的环境影响潜值,占到全部的86.81%,表明降低卫生填埋环境影响的关键是对产生的C_(2)H_(4)等进行收集处理;其次是全球变暖贡献了12.45%,酸化、富营养化和生态毒性的贡献较小,分别为0.38%、0.36%和0.00001%。研究结果对重庆城市生活垃圾的管理和城市生态环境保护具有重要的意义。Based on the principles and theoretical framework of Life Cycle Assessment,a systematic LCA evaluation is conducted on the collection,transportation,and landfill stages of a municipal solid waste sanitary landfill site in the main urban area of Chongqing.The study determines the scope and objectives,selects appropriate environmental impact factors for Chongqing,and conducts inventory analysis and environmental impact potential calculations.The evaluation results show that photochemical ozone synthesis contributes the most to the environmental impact potential during the sanitary landfill process,accounting for 86.81%of the total,indicating that the key to reducing environmental impact of sanitary landfill is to collect and treat emissions such as C_(2)H_(4).Global warming contributes 12.45%,while acidification,eutrophication,and ecological toxicity have smaller contributions,accounting for 0.38%,0.36%,and 0.00001%respectively.The research findings are of great significance for the management of municipal solid waste and urban ecological environment protection in Chongqing.
