基于文献计量的泥石流研究现状与国际研究态势分析

Research Status and International Research Situation Analysis of Debris Flow Based on Bibliometrics

泥石流灾害点多、面广,危害严重,因此探明国内外泥石流研究现状对防灾减灾工作有重要意义。文章以1938—2019年Web of Science核心合集库收录的泥石流领域发表的11466篇文献为研究对象,借助VOSviewer等软件绘制知识图谱,分别从论文数量年度变化趋势、重点国家发文量、国家/地区合作关系、主要研究机构和篇被引频次、主要作者、高被引文献、研究热点、热点演化趋势进行分析,以知识图谱分析并揭示泥石流研究领域近年来的研究现状、前沿热点与演化趋势。

There are many disaster points and wide areas of debris flow,and disaster prevention and mitigation work is urgent.Therefore,it is of great significance to the work of debris flow disaster prevention and mitigation.This article takes 11466 documents published in the field of debris flow included in the core collection of Web of Science from 1938 to 2019 as the research object,draws a knowledge map with the help of software such as VOSviewer,this paper analyzes the annual change trend of the number of papers,the number of papers published by key countries,the cooperation relationship between countries and regions,main research institutions and citation frequency of papers,main authors,highly cited literature,research hotspots,and hot spot evolution trend,respectively,and reveals the research status,frontier hot spots and evolution trend of debris flow research field in recent years with knowledge graph.
