摘要: 在生命周期评价(Life Cycle Assessment, LCA)方法中,利用资源稀缺度因子,可以综合评价一个产品生命周期中总体的资源消耗水平。论文基于广泛采用的CML方法中的非生物资源消耗(Abiotic Depletion Potential, ADP)因子,通过引入中国的资源自给率修正,得出了中国非生物资源消耗因子(Chinese Abiotic Depletion Potential,CADP)及其指标。CADP因子可支持国内LCA研究和相关政策研究中的资源、能源消耗综合评价,同时也为其他国家或地区的资源评价提供了一种普遍适用的方法。案例研究表明,1 kWh电网电力的生命周期CADP指标为1.02 kg coal-R eq.,60.46%的贡献都来自于原煤资源的消耗,其次来自石油的消耗(11.63%),此外还包括基础设施建设中铜、镍等资源的消耗。

Abstract: With the scarcity factors of resources and energy, the overall resource consumption along a product life cycle can be evaluated in LCA(Life Cycle Assessment) studies. In this paper, CADP (Chinese Abiotic Depletion Potential) factors of various resources and fossil energy in the Chinese context were obtained by adopting the broadly used Abiotic Depletion Potential (ADP) factors in CML methods and modifying them with self-sufficiency rate of individual resources in China. The factors will support the assessment of resource and energy consumption for LCA studies and relevant policy studies in China. It also provides an adaptable method for other national or regional analysis. The case study shows that the CADP of 1 kWh grid power is 1.02 kg coal-R eq. The 60.46% of contribution comes from the coal consumption, then from oil consumption (11.63%), and the consumption of other resources like copper, nickel etc. in infrastructure construction also contributes.

Key words: scarcity degree, Life Cycle Assessment (LCA), Chinese Abiotic Depletion Potential (CADP), mineral resource
