国内外城市地下空间研究知识图谱分析

Analysis on the knowledge mapping of foreign research on urban underground space

针对城市地下空间的研究进展问题,该文借助信息可视化软件CiteSpace将Web of Science中城市地下空间相关文献进行知识图谱分析,在梳理现有研究脉络的基础上,总结其研究热点与演化历史,为后续研究提供参考。通过对文献的合著特征分析、文献共被引分析以及关键词共现分析,发现城市地下空间相关研究最活跃的国家是加拿大,最活跃的作者是李焕青;城市地下空间开发前的预测和规划是一直以来研究的热点;城市地下空间研究主题归纳为3条演化路径,包括以地下建筑为侧重点的城市地下开发利用,城市地下工程建设以及城市地下空间规划。国内外现有城市地下空间研究已形成一定的研究体系架构,国际合作研究日益增多,相关研究学科交叉性强。未来城市地下空间研究趋势和热点将集中在城市地质、地下潜力与开发效益评估、地下空间信息化等方面。

In order to study the research progress of urban underground space,the paper analyzes the knowledge map of urban underground space in Web of Science by information visualization software CiteSpace.Based on the review of existing research context,this paper summarizes the research hotspots and evolutionary history,study for reference.Through the analysis of the co-authored documents,co-citation analysis and keyword co-occurrence analysis,it is found that Canada is the most active research area for urban underground space related research and Li Huanqing is the most active author.Prediction and planning of urban underground space development is the hot spot of research all along.The theme of urban underground space research can be summarized as three evolutionary paths,including underground development and utilization of underground buildings,underground urban construction and urban underground space planning.At present,the research on underground space in existing cities at home and abroad has formed a certain research system structure.The research on international cooperation is increasing day by day,and the relevant research disciplines are quite interdisciplinary.Future urban underground space research trends and hot spots will focus on urban geology,underground potential and evaluation of development benefits,underground space information etc.
