基于VOSviewer南水北调研究热点分析

Analysis of research hotspots in South-to-North Water Diversion based on VOSviewer

文章通过研究主题热点分析和研究机构分析,揭示南水北调主题研究的特点。基于中国知网(CNKI)数据库,借助VOSviewer软件,对南水北调主题研究进行分析,并从作者机构角度对研究的合作情况进行分析和主题内容解读。研究表明:研究热点包括了倒吸虹工程的设计与优化研究、渡槽工程研究、穿黄工程研究,膨胀土(岩)研究等4个方面;高产的研究机构主要是与水利水电专业相关的科研院所,分布于南京、北京、郑州、武汉等地;高产研究机构在研究合作中占据核心地位;团队合作研究跨地域性比较强。

This paper reveals the characteristics of the theme research of the South-to-North Water Diversion project through the analysis of research topics and research institutions.Based on CNKI database and with the help of VOSviewer software,this paper analyzes the theme research of the South-to-North Water Diversion project,and analyzes the cooperation of the research and interprets the theme content from the perspective of the author’s organization.The research shows that the research hotspots include the design and optimization of inverted siphon project,aqueduct project,Yellow River Crossing project and expansive soil(rock)research;the high-yield research institutions are mainly scientific research institutions related to water conservancy and hydropower,distributed in Nanjing,Beijing,Zhengzhou,Wuhan and other places;high-yield research institutions occupy a core position in research cooperation;team cooperation research is more cross regional.
