基于知识图谱的高位远程滑坡碎屑流研究热点及趋势分析
Research Hotspot and Trend Analysis of Debris Flow of High Level Remote Landslide Based on Mapping Knowledge Domain

本文以“高位远程滑坡碎屑流”为主题词，在CNKI中国知网上搜集了有关“高位远程滑坡碎屑流”的241条文献数据，并通过CiteSpace软件进行可视化分析，以此来了解当前高位远程滑坡碎屑流领域的发展趋势及目前的研究热点问题。研究结果表明：1) 自2008年汶川地震后，国内关于高位远程滑坡碎屑流的研究开始越来越受到重视，文章数量在不断增长；2) 发文作者和发文机构主要集中在我国西南地区，其中西南交通大学形成一家独大的局面，其发文量占总量的20.3%；3) 通过绘制关键词共现图谱并综合运用词频，中心度和聚类的分析方法进行研究后发现，“数值模拟”、“碎屑流”、“动力破碎”等是近年来的研究热点词汇，就此分析可知，目前关于高位远程滑坡碎屑流领域的前沿是有关“数值模拟”以及“碎屑流”等方向的研究。本文通过对2006年~2022年“高位远程滑坡碎屑流”领域所发表的文献进行可视化分析，以期为广大读者清晰地梳理这一领域近几年的研究成果及研究热点，进而对相关研究人员跟踪这一领域的近期研究热点及未来发展趋势有所帮助。
This paper takes “high level remote landslide debris flow” as the theme word, collects 241 literature data about “high level remote landslide debris flow” on CNKI China Knowledge Network, and makes visual analysis through CiteSpace software, so as to understand the current development trend and current research hot issues in the field of high level remote landslide debris flow. The results show that: 1) Since the Wenchuan earthquake in 2008, more and more attention has been paid to the research on the debris flow of high level remote landslides in China, and the number of articles has been growing; 2) the authors and organizations of the articles are mainly concentrated in the southwest of China, among which Southwest Jiaotong University is the largest, accounting for 20.3% of the total; 3) through the keyword co-occurrence atlas, combined with word frequency, centrality, clustering and other analysis methods, it is found that “numerical simulation”, “debris flow”, “dynamic fracture” and other research hot words in recent years. From this observation, it can be concluded that the current frontier of the field of high-level remote landslide debris flow is the research on “numerical simulation” and “debris flow”. This paper makes a visual analysis of the literature published in the field of “high level remote landslide debris flow” from 2006 to 2022, with a view to clearly sorting out the research achievements and research hotspots in this field in recent years for the majority of readers, thus helping relevant researchers to track the recent research hotspots and future development trends in this field.
