摘　　要：城市人口聚集与城市化扩张促成了城市的高密度发展态势,而高人口密度和高建设密度的建成环境引发和加剧了一系列环境问题,极端天气频发更是引起了公众对高密度建成区室外热环境的重视和思考。本文借助CiteSpace软件对2014-2024年中国知网(CNKI)核心期刊收录的699篇关于高密度建成区室外热环境相关文献进行研究热点与趋势的梳理。结果表明:①研究热点方面,我国高密度建成区室外热环境关注重点由城市热岛向热舒适偏移,以人为中心的热环境研究正成为主要趋势;②研究尺度方面,高密度建成区热环境研究呈现多尺度效应,数据采集方法和研究要素日益多样化。本文总结了高密度建成区室外热环境研究特点并提出了未来展望,以期在城市规划与更新中为提升人居环境舒适度提供参考。The concentration of urban population and the expansion of urbanization have led to a high-density development trend in cities,while the built environment with high population density and high construction density has triggered and exacerbated a series of environmental problems.The frequent occurrence of extreme weather has also aroused public attention and reflection on the outdoor thermal environment of high-density built-up areas.This paper uses CiteSpace software to sort out the research hotspots and trends of 699 articles related to outdoor thermal environment in high-density built-up areas included in core journals of China National Knowledge Infrastructure(CNKI)from 2014 to 2024.The results show that:①in terms of research hotspots,the focus of attention on outdoor thermal environment in high-density built-up areas in China has shifted from urban heat islands to thermal comfort,and human centered thermal environment research is becoming the main trend;②in terms of research scale,the study of thermal environment in high-density built-up areas presents multi-scale effects,with increasingly diverse data collection methods and research elements.Finally,this paper summarizes the research characteristics of outdoor thermal environment in high-density built-up areas and proposes future prospects,in order to provide a reference and guidance for improving the comfort of living environment in urban planning and renewal.
