水利水电工程全生命周期碳排放研究——以犬木塘工程为例

Life cycle carbon emissions of water reservoir and hydroelectric projects:A case study of the Quanmutang project

水利水电工程具有多种功能,发挥着各方面效益,在“双碳”战略中扮演着重要角色,但目前针对水利水电工程全生命周期碳排放的研究还较少。该文以湖南省犬木塘工程为样本,基于生命周期评价理论,提出了水利水电工程碳排放量的分组计算方法,对碳排放进行了核算和分析。研究表明,此计算方法简单准确,更适用于水利水电工程。计算结果显示,犬木塘建设和运行阶段总体碳排放风险可控,并依据其碳排放特点,提出了注重设计优化、研发绿色建材、加快智慧化、强化减排理念等降低碳排放的策略。

Water reservoirs and hydroelectric projects have many functions that produce great benefits that will play an important role in the“double carbon”strategy.However,there are few studies on the life cycle carbon emissions of hydropower and reservoir projects.This study uses the Quanmutang project in Hunan Province as an example to apply life cycle assessment theory and the carbon emissions grouping calculational method which is more suitable for reservoirs and hydroelectric projects.The carbon emission calculations show that the overall carbon emissions during the construction and operating phases of the Quanmutang project are controllable.This study then considers the carbon emission characteristics to present some strategies to reduce the carbon emissions,such as design optimization,developing green building materials,accelerating intellectualization and strengthening the emission reductions.
