基于可视化图谱的城市洪涝研究热点及发展趋势

Research Hotspots and Development Trends of Urban Floods Based on Visual Maps

摘要: 对国内城市洪涝领域进行梳理并预测其研究进展，探索其演化脉络，可为后续学者研究提供思路和启发。基于CiteSpace可视化分析软件，结合文献计量法，对CNKI数据库中1999~2021年之间以“城市洪涝”为主题的315篇文献进行可视化分析。结果表明：历年来文献发表的数量逐年增加且趋势尚未有减弱现象；研究此领域的作者逐年增加，核心作者群初步成熟但大多数学者缺乏横向交流，领域的研究还处于初级阶段；机构的数量逐年增加，机构之间的学术合作在未来将更加明显；“防洪排涝”、“海绵城市”、“Netlogo”是当前的研究热点，也是当前最需要解决的问题。最后在文献研读的基础上，就城市洪涝研究的领域提出了几点建议，以供后续学者参考。

Abstract: To sort out and predict the research progress of urban flood in China and explore its evolutionary context can provide ideas and inspiration for the subsequent researches. Based on CiteSpace visualization analysis software and literature measurement method, 315 literatures with the topic of “Urban Flood” in CNKI database from 1999 to 2021 were analyzed visually. The results show that the number of published literatures has been increasing year by year and the trend has not abated. The number of authors in this field is increasing year by year, the core author group is mature, but most scholars lack horizontal communication, and the research in this field is still in the initial stage. The number of institutions is increasing year by year, and academic cooperation between institutions will be more obvious in the future. “Urban Flood”, “Sponge City” and “Netlogo” are the current research hotspots and the most urgent problems to be solved. Finally, on the basis of literature study, some suggestions on the field of urban flood research are put forward for the ref-erence of subsequent scholars.
