生命周期环境影响类型分类体系研究

Study on Classification System of Life-cycle Environmental Impact Categories

环境影响类型是生命周期影响评价价(LCIA)中重要的一步,其分类国际上目前尚未达成共识。文章分析了环境干扰因子与环境影响类型之间的关系,确定了影响类型分类的原则和步骤,通过对EPA、SETAC方案的比较,提出了3×3方案,从全球、区域和局地3个层次,涉及环境污染、资源消耗和人体职业健康3方面的影响体系框架,并提出了其6项量化表征指标。

The definition of environmental categories is a very important step in the stage of life-cycle impact assessment. However the flamework of environmental categories has not yet set up in the world. Based on analysis of interaction between environmental exchange and environmental categories, the principle and procedure were developed, a new framework and indicators were developed in context of environmental pollution and damage, resources consumption and occupational health at global, regional and local scales.
