摘　　要：基于CNKI数据库,利用文献计量软件CiteSpace对1992—2022年关于城市热岛效应的相关论文的发文量、作者、机构和关键词进行可视化分析。通过CiteSpace软件的可视化研究成果,对我国城市热岛效应的研究现状、发文趋势和研究热点进行了系统梳理,为后续该领域的深入研究提供参考。研究结果表明:①由文献计量分析可知,城市热岛效应的研究发展呈现出明显的阶段性特征,1992—2003年缓慢增长,2003—2011年增长迅速,2009—2022年出现较大波动;发文量变化与作者机构合作网络变化之间存在较强关联性;研究主要集中在城市化发展迅速的大城市,多学科交叉的综合性研究较少,且研究主体较为分散。②由关键词的聚类分析和突现词的探测与分析可知,作为城市气候变化的指征,在城市气候研究中城市热岛对城市气候的影响是重要研究内容,而城市热岛效应与景观格局之间的关系是城市热岛效应的重要研究方向之一;城市热岛的时空分布、形成与演化机制以及缓解和应对的措施研究是当前和未来城市热岛效应的研究方向与发展趋势。Based on the CNKI database,we used the bibliometric software CiteSpace to visually analyze the number of papers,authors,institutions and keywords of relevant papers on urban heat island effect from 1992 to 2022.Through the visualization research results of CiteSpace software,we systematically sorted out the research status,publication trend and research hotspots of urban heat island effect in China,which provided reference for subsequent in-depth research in this field.The results show that①based on the quantitative analysis of literature,the research and development of urban heat island effect shows obvious stage characteristics,with slow growth from 1992 to 2003,rapid growth from 2003 to 2011,and large fluctuations from 2009 to 2022.And,there is a strong correlation between the changes in the number of papers issued and in the cooperation network of author’s organization.The researches are mainly concentrated in large cities with rapid urbanization development.There are few comprehensive interdisciplinary studies,and the research subjects are scattered.②From the cluster analysis of keywords and the detection and analysis of emergent words,it can be seen that,as an indicator of urban climate change,the influence of urban heat island on urban climate is an important research content in urban climate research,and the relationship between urban heat island effect and landscape pattern is one of the important research directions of urban heat island effect.The spatio-temporal distribution,formation and evolution mechanism of urban heat island as well as mitigation and countermeasures are the research direction and development trend of urban heat island effect at present and in the future.
