国内外建筑业碳排放的研究评述——基于Citespace的计量分析

A Review of Researches on Carbon Emission of Domestic and Abroad Construction Industry——Measurement Analysis Based on Citespace

建筑业是全球碳减排的重点领域,近年来,建筑业碳排放逐渐成为行业的研究热点。以CNKI库的467篇中文文献和SCI数据库的561篇相关文献为数据来源,运用Citespace可视化软件,从建筑业碳排放研究热点、关键文献对比分析、演化趋势研究等方面,对国内外建筑业碳排放可视化进行了对比分析。结果表明:在研究热点方面,国外学者更多聚焦“温室气体排放”“生命周期评估(LCA)”方面,国内学者关注建筑碳排放的影响因素及其量化方法;在关键文献方面,国内外研究的偏好各有侧重,国外期刊源中的文献更多地偏向于对工程中具体的碳排放量的测算分析,而国内的文献偏向于宏观层面上广义的分析,更注重理论部分;在研究趋势方面,国外趋于物理结构学、化学因子和生物仿真学等自然科学知识在建筑业碳排放中的应用,国内更注重经济分析学、管理因素学、环境科学等学科在建筑业碳排放中的应用。现如今,新旧技术的集成应用及其信息化将成为建筑业碳排放的重点研究对象。

The construction industry is the key field of global carbon emission reduction. In recent years, the research on the carbon emission of the construction industry has gradually become the research hotspot of the industry. Taking 467 Chinese literatures from CNKI database and 561 related literatures from SCI database as data sources, this paper uses CiteSpace visualization software to make a comparative analysis of carbon emissions visualization in the construction industry at home and abroad from aspects of research hotspots, comparative analysis of key literatures and evolution trend research. The results show that in terms of research hotspots, foreign scholars focus more on "greenhouse gas emissions" and "life cycle assessment(LCA)", while domestic scholars focus more on the influencing factors of building carbon emissions and their quantification methods. In terms of key literatures, domestic and foreign researches have different preferences. Foreign journals tend to calculate and analyze the specific carbon emissions in the project, while domestic literatures tend to analyze in a broad sense at the macro level and pay more attention to the theoretical part. In the research trend, foreign countries tend to physical structure, chemical factors and biological simulation and other natural science knowledge in the construction industry carbon emissions application;China pays more attention to the application of economic analysis, management factors, environmental science and other disciplines in construction industry carbon emissions. Nowadays, the integrated application of new and old technologies and their informationization will become the key research object of carbon emissions in the construction industry.
