建筑生命周期评价作为一种评估资源消耗和环境影响的主流方法,对我国实现碳中和目标具有重要意义.为揭示国内外建筑生命周期评价研究概况,以"Web of Science"和"CNKI"中的建筑生命周期评价期刊文献为对象,利用CiteSpace和VOSviewer绘制了该领域研究的总体特征和演化进程知识图谱,以期为进一步的研究提供参考.分析表明:在研究内容上,国外生命周期评价研究多学科交叉,涵盖能源利用、环境效益和经济效益等多个方面,已从细分阶段进入到整合阶段;而国内研究更多从建筑和环境学科出发,侧重于建筑节能减排,目前处于多元细分阶段,存在体系发展不平衡的问题.在研究方法上,国内外建筑生命周期评价均以量化清单为基础,但具体的评价指标与技术路径存在差别,国外在LCA不确定性分析方面较为领先,而国内在此方面处于起步探索阶段.未来国内建筑LCA研究应关注对框架体系的扩展与完善,重视从建筑单体到群体、从单学科到多学科的变化趋势,并加强对建筑LCA不确定性的关注.
As a mainstream method for evaluating resource consumption and environmental impact,building Life Cycle Assessment(LCA)is of great significance for China to achieve its carbon neutrality goal.To reveal the research status of building LCA both domestically and internationally,the research systematically maps the general characteristics and evolution of the researches in building LCA field based on related literatures from Web of Science and CNKI databases.The analysis shows that in terms of research content,foreign LCA studies are interdisciplinary,covering multiple aspects such as energy use,environmental benefits,and economic benefits,having entered the integration stage from the subdivision stage.Domestic research starts more from the disciplines of building and environment,focusing on energy conservation and emissions reduction,and is currently in the stage of multiple subdivisions,with the problem of imbalanced system development.In terms of research methods,both domestic and foreign building LCA are based on quantified inventories,however,with differences in specific evaluation indicators and technical paths.Foreign research is more advanced in LCA uncertainty analysis,while domestic research is in the initial exploration stage.In the future,domestic research should focus on the expansion and improvement of the framework system,pay attention to the trend of change from single building to group,and from single discipline to multi-discipline,as well as strengthen attention to building LCA uncertainty.
