Green and low-carbon construction strategies for river regulation projects based on LCA carbon emission accounting and multi-scenario analysis: a case study of Jurong River in Nanjing

  • 摘要: 河道整治工程的绿色低碳建设是“双碳”目标下水利工程绿色转型的重要内容。针对传统河道整治工程绿色低碳建设策略定性描述多、生命周期评价(life cycle assessment,LCA)少、过程解析多、多场景指导少的共性问题,以南京市句容河整治工程示范段为例,在LCA评价识别河道整治工程碳排放特征的基础上,利用环境/经济二元模型对绿色低碳建设技术的选择进行了不同目标下的情景分析,形成了相应的绿色低碳建设技术措施的组合策略。结果表明:句容河示范段(长度8.46 km)建设期碳排放强度为2705 t CO2eq/km,其中,原材料生产阶段占比最高达92.49%,其次依次为工程建设阶段5.75%>工程运输1.06%>工程准备0.70%。多情景分析显示:采用低碳新能源运输、粉煤灰及再生混凝土等措施,可实现减碳4486 t CO2eq,产生108.14万元的最优经济价值;采用粉煤灰、再生骨料混凝土及碳捕捉水泥(替代率达90.32%)等组合,可减碳7551 t CO2eq,实现经济与环境绩效均衡;实施全部降碳措施可减碳9596 t CO2eq,但需投入113.37万元。经济效益最大化情景与经济生态平衡情景更具工程适用性,可为河道整治工程的绿色低碳建设提供决策依据。
