生态生命周期评价(Eco-LCA)作为常规生命周期评价的拓展,提供了一种对工业过程生态影响及可持续性分析评价的方法.但目前Eco-LCA中尚缺失生态累积耗(ECEC)指标的完整模型.本文探讨了工业过程中自然资源消耗、社会经济投入和环境污染危害三种主要影响因素.通过构建囊括资源、经济、环境三要素的工业过程生态累积耗模型,完善了Eco-LCA方法应用于工业过程可持续分析的理论框架.最后,以此生态累积耗模型对中国原油生产进行了示例性分析讨论.
As an extension of routine life cycle assessment, Eco-LCA provides a method to analyze and assess the ecological impact and sustainability of industrial processes, but Eco-LCA still lacks ecological ECEC (Eco-LCA) Index.This paper discusses three main influencing factors of natural resource consumption, social economic investment and environmental pollution hazard in industrial process.Through the construction of eco-cumulative consumption model of industrial process including resources, economy and environment, -LCA method is applied to the theoretical framework of sustainable industrial process analysis.Finally, an example of China’s crude oil production is discussed and discussed based on the model of ecological accumulation and consumption.
