【摘要】 本文在全面综述生命周期评价的技术演变及研究现状的基础之上建构起以ISO14040生命周期评价—原则和框架为指导原则的城市生活垃圾处理系统生命周期评价模型，并进一步深入建立起综合了环境可持续性、经济可承受性、社会可接受性以及技术可行性多方面因素的多因素评估模型。围绕城市生活垃圾处理系统生命周期评价模型，在环境影响定量化方面引入了环境影响潜值的计算方法；在多因素评模型中，使用了基于隶属度的模糊识别方法，并首次系统的将模糊综合评判方法应用于城市生活垃圾处理系统的生命周期评价领域，从而在环境影响定量化和多因素综合评判方面为生命周期评价提供了工具，使城市生活垃圾处理向着可持续的方向发展。更多还原

【Abstract】 On basis of summarizing the evolvement of techniques and the state of life cycle assessment (LCA), the paper establishes a set of LCA model on municipal waste (MSW) treatment system which is supervised by ISO 14040 Environmental Management -Life Cycle Assessment- Pricipals and Framework. In addition, the paper has set up a multi-factors evaluating model of life cycle impact assessment integrating acpects on environmental sustainability, economy capability, society acceptability and technology feasibility. In order to realize environment impact quantification, the calculation of environmental impact potential are introduced. Furthermore, fuzzy comprehensive methods based on relative membership degree have been applied to the MSW life cycle assessment fields for the first time. These methods can provide effective tools for LCA environment impact quantification and multi-factors comprehensive evaluation, by using it, the municipal solid waste treatment will consequentially develop in a more sustainable way.更多还原
