| 中文摘要 |
| 影响分析是LCA的核心内容,也是难度最大的部分。目前采用的定性方法和定量方法都存在不少缺点。本文在笔者构筑的LCA指标体系的基础上探索在影响分析中引入我国现行的环境质量评价方法和手段使影响分析的方法更易于操作,其结果更具有客观性和可比性。本文论述了各项评价指标的计算方法及要素指标的形成并指出利用5个要素指标的数据能比较全面地反映产品的环境性能。 |
| 英文摘要 |
| The impact analysis is a key part in LCA. It is also the most difficult one in LCA.There are some disadvantages for both the exisiting qualitive and quantitative approaches.On the basis of the LCA index system proposed by authors earlier,the method of environmental quality assessment has been introduced to the impact analysis in this study,which makes the impact analysis much easier than before.Moreover,the obtained results are rather objective and comparable.This paper illustrates the estimation approaches for evaluation indexes and explains how to form the essential index system.It has been pointed out that the use of 5 essential indexes should be enough for defining the environmental properties of a product comprehensively. |
