摘　　要：为系统分析分配规则对废旧纺织品回收再利用生命周期评价(Life Cycle Assessment,LCA)结果的影响,梳理并比较了相关研究中的分配规则,重点分析了不同分配规则下再生产品的生命周期评价结果的差异。结果表明:截止分配规则简单易用,但可能导致环境影响重复计算和分配不公的问题;经济分配规则能够反映市场动态,但易受市场价格波动影响;50/50规则平衡了前后生命周期的环境影响,但未能反应回收的实际情况;循环足迹公式提供了更为全面的分配方式,但要求更详细的数据支持。在废旧纺织品回收再利用生命周期评价中合理选择分配规则并规范使用,有助于促进回收再利用体系中产品生命周期评价的标准化。In order to systematically analyze the impact of allocation rules on the life cycle assessment(LCA)results of recycling and reuse of waste textiles,a review and comparison of allocation rules from relevant research are presented,with a particular focus on the differences in LCA results for the reused products under various rules.The results show that the cut-off allocation rule is simple to use but may lead to the problem of repeated environmental impact calculations and unfair distribution.The economic allocation rule can reflect market dynamics,but are susceptible to the impact of market price fluctuations.The 50/50 rule balances the environmental impacts of the front and back life cycles,but it does not reflect the actual recycling situation.The Circular Footprint Formula provides a more comprehensive allocation method,but it requires more detailed data support.Selecting and standardizing the use of allocation rules in the LCA of waste textile recycling and reuse can facilitate the standardization of product LCA within the recycling and reuse system.
