基于CiteSpace的国内公路洪灾研究知识图谱分析

频繁发生的公路洪灾严重影响公路畅通和社会经济发展，为推动国内公路洪灾学科在理论和实践中有进一步的发展，利用CiteSpace V.5.3.R4绘制我国公路洪灾研究的知识图谱，对该领域1987~2019年的研究动态进行综合分析，识别学科发文数量的时间分布特征，完成研究作者、发文机构、关键词共现分析以及阶段性研究前沿突现分析。结果表明：学术期刊占论文总数的64.84%，硕士学位论文占27.65%，博士学位论文与会议论文分别占4.93%、2.58%，研究成果随时间呈波动增长趋势；学科研究主要有长安大学、中科院成都山地灾害研究所以及重庆交通大学三大研究团体，团体间互引关系相对较弱，学术交流需进一步加强；西南地区主要发文机构间的学术联系比西北地区间的联系较为密切，不同地域特色造成目前国内尚未形成广泛的学术共识；国内公路洪灾研究发展历程可分为探索、起步、繁荣发展、稳定四个阶段。研究结果可为国内公路洪灾的后续理论研究和实践探索提供参考依据。

Knowledge Mapping Analysis of Domestic Highway Flood Disaster Research Based on CiteSpace

Frequent highway-floods seriously affected the smooth flow of roads and social and economic development, in order to promote the domestic highway-flood discipline, there is further development in theory and practice, using CiteSpace V.5.3.R4 to map the knowledge map of highway-flood disaster research in China, comprehensively analyzed the research dynamics of this field from 1987 to 2019, identified the time distribution characteristics of the number of documents issued by the discipline, and completed the co-occurrence analysis of authors, organizations and keywords. And emergent analysis of the frontiers of phased research. The results show: Academic journals accounted for 64.84% of the total number of papers, master''s papers accounted for 27.65%, doctoral dissertations and conference papers accounted for 4.93% and 2.58% respectively, and the research results showed a trend of volatility growth with time; The subject research mainly includes Changan University, Chengdu Institute of Mountain Disasters of Chinese Academy of Sciences and Chongqing Jiaotong University.The relationship between the teams is weak, the academic exchange needs to be strengthened; the academic links between the main organizations in the southwestern region are closer than those in the northwestern region, and different regional characteristics have not yet formed a broad academic consensus in China; The development history of domestic highway-flood research is divided into four stages: exploration, start-up, prosperity and stability. The research results can provide reference for the follow-up theoretical research and practical exploration of domestic highway-floods.
