公园降温研究进展与趋势图谱量化分析

Visualized Quantitative Analysis of Progress and Trend in Park Cooling

伴随城市热岛效应的研究和环境生态意识的觉醒,公园降温的研究成为热点.以Web of Science数据库收录的发表于1990—2020年的980篇公园降温研究的SSCI文献为研究样本,借助CiteSpace软件对文章数量、机构、引文编年图、文献共引图、关键词共现网络图等分析,从经典文献和前沿文献梳理近30年国际公园降温的研究脉络、研究热点和发展趋势.研究发现:公园降温文献共被引聚类分为:降温效应、能源节约潜力、空气温度、冷岛强度和热舒适.研究热点包括:实地测量、微气候模拟和遥感反演等公园降温分析技术手段之间的互相验证;应从宏观和微观两个维度,对公园及周边区域环境综合分析;扩展公园降温影响因子的深度研究.

With the study of urban heat island effect and the awakening of environmental ecological awareness,study of park cooling has become a hot spot.This paper takes the 980 SSCI literatures of Park cooling published in 1990—2020(web of Science)as the research samples.With the help of CiteSpace software,we analyzed the number of articles,institutions,citation chronology map,literature citation map,keyword co-occurrence network map,and combed the research context,research hotspot and development trend of park cooling abroad in the past 30 years from classic literature and recent literature.The park cooling literature is divided into five categories:cooling effect,capacity saving potential,air temperature,cold island strength and thermal comfort.The research focuses include:mutual verification of park cooling analysis techniques such as field measurement,microclimate simulation and remote sensing inversion;comprehensive analysis of park and surrounding regional environment from macro and micro dimensions;in-depth study of park cooling impact factors.
