中国泥石流研究热点与前沿——基于中国知网的文献分析

Research hotspot and frontier of debris flow in China——Literature analysis based on CNKI literature

根据知识图谱理论,运用Citespace可视化分析软件,对1992-2020年期间,我国在泥石流研究方面的1799篇基于CNKI高质量文献进行分析研究,全面梳理了我国泥石流研究现状、研究工作的热点和发展前沿.得出:(1)我国泥石流灾害研究文献数量经过了起步、爆发及平稳三个阶段;(2)泥石流的合作研究不聚焦,研究方向较为分散;(3)泥石流灾害的研究热点主题集中于地质灾害链、泥石流特征、危险性评价及方法模型等4个方面;(4)方法模型、监测预报与大型泥石流的危险性评价将成为我国泥石流灾害研究领域未来的核心主题.研究结果为我国学者探寻泥石流灾害研究的方向和趋势提供参考.

Based on the Knowledge Atlas Theory and using the Citespace visual analysis software,this paper analyzes and Studies 1799 high-quality documents of debris flow research in China from 1992 to 2020 based on CNKI,in this paper,the research status,research hotspots and development frontiers of debris flow in China are reviewed,and 18 emergent words of debris flow disaster are obtained.The results are as follows:(1)the number of literatures on debris flow disaster in China has gone through three stages:initial stage,explosion stage and steady stage.(2)he cooperative research on debris flow is not focused and the research direction is scattered.(3)the research hot topics of debris flow disaster focus on the geological disaster chain,the characteristics of debris flow,the risk assessment and the method model.(4)method model,monitoring and forecasting and risk assessment of large-scale debris flow will become the core topics in the future research field of debris flow disaster in China.The research results can provide references for Chinese scholars to explore the direction and trend of debris flow disaster research.
