| 摘 要： | 非生物性资源的耗竭是生命周期评价中关注的重要环境问题之一.目前该类资源耗竭潜力的特征化因子还多使用Guinée等10多年前提出的数据,随着时间的变化,这些数据是否仍然有效,是一个值得关注的问题.利用最近几年的资源消耗数据,计算了2004～2009年全球主要资源的耗竭潜力特征化因子,并与1995年数据进行了比较,发现除个别年产量有较大变化的资源外,大多数资源的耗竭潜力特征化因子均无大的变化,表明以往采用Guinée等（1995）提出的特征化因子所开展的绝大多数案例研究结果受时间变化的影响较小,具有较好的可比性和可信度.

| Abstract: | The abiotic resource depletion is an important environmental problem concerned in life cycle assessment(LCA).Up to now,the characterization factors(CFs) of abiotic resource depletion adopted by many LCA practitioners are from Guinée.It is a noteworthy question that whether these CFs is still in effect or not.Based on the annual global resource production datum in recent years,the CFs of main abiotic resource depletion during 2004—2009 is calculated.Comparing CFs during 2004—2009 with that in 1995,it shows there are no pronounced changes except individual resources which have clear variations in annual production.It was found that the many results derived from case studies by using CFs from Guinée~ show strong stability,comparability and reliability with time. |
