Study on map analysis and trend prospect of campus thermal environment based on CiteSpace

Abstract

Objective To grasp the research dynamics and development trend of the thermal environment of campus buildings in China, so as to lay the foundation for in-depth research and provide a reference basis.

Methods Based on 479 documents in CNKI from 2000 to 2020, the documents were visualized and analyzed by keywords, including co-occurrence, clustering, outbreak and author cooperation network in CiteSpace.

Results In the past 20 years, the research on thermal environment of campus buildings in China had gone through a period of formation-development-growth, and was at a high growth stage now. The word frequency of “thermal comfort, thermal environment, indoor thermal environment, natural ventilation” was greater than 50, which was a high-frequency keyword. The highest outbreak rate of “green campus” was 3.75, and “university library, university building, microclimate and green building” was in the outbreak period. And LIU Jiaping, LIU Zehua, WANG Hongguang and others were highly productive authors and have formed cooperative network groups with their own cores, but the cooperation among the network groups was less to be strengthened.

Conclusion The research dynamics of the thermal environment of campus buildings is closely related to the policy development in China, and the research on “green campus, campus energy-saving optimization, and university buildings” based on human thermal comfort theory is a hot topic of continuous attention.

【摘要】 目的 掌握中国校园建筑热环境的研究动态及发展趋势, 为未来校园建筑发展提供参考依据。 方法 以中国知 网(CNKI)数据库中2000—2020年的479篇有效文献为基础, 通过CiteSpace中的关键词共现、聚类、爆发和作者合作网络 等方法对文献进行可视化分析。 结果 近20年中国在校园建筑热环境方面的研究经历了形成期-发展期-增长期; “热舒 适、热环境、室内热环境、自然通风”词频均大于50, 是髙频关键词;“绿色校园”的爆发率最髙为3.75, “髙校图书馆、髙校建 筑、微气候、绿色建筑”正处于爆发期;刘加平、刘泽华、王洪光等是髙产作者, 且以各自为核心形成了合作网络群, 但各网 络群间的合作较少。 结论 校园建筑热环境的研究动态与中国政策发展联系紧密, 以人体热舒适理论为基础, 针对“绿色 校园、校园节能优化、髙校建筑”方面的研究仍将会是持续关注的热点课题。
