基于国内外节水灌溉科技文献可视化分析

Visual Analysis on Domestic and Foreign Water-saving Irrigation Scientific Literature

为探究当前国内外节水灌溉研究趋势和热点,基于CNKI和WOS核心数据库,检索2002-2021年关于节水灌溉的科技文献,利用VOSviewer可视化分析软件及数据库分析结果,对年发文量、发文国家和机构、发文期刊、高产作者和高引文献、研究主题以及关键词进行分析。结果表明:在2002-2021年,CNKI数据库年发文量波动较大,而WOS数据库发文量总体呈上升趋势,其中中国科研机构已经成为WOS数据库发文主力军;该领域文献主要发表在《节水灌溉》、《中国农村水利水电》、《灌溉排水学报》、《Agricultural Water Management》等期刊上,其中,《节水灌溉》发文量最高(752篇);该领域CNKI数据库发文量最高的作者为河海大学彭世彰教授,发文量为42篇,而WOS数据库发文量最高的作者为佛罗里达大学Dukes Michael D教授,发文量为28篇;该领域研究方向主要集中在灌溉方式、灌溉制度、水分利用效率等方面。节水灌溉研究在今后仍然是热点问题,我国科研工作者在该领域具有重大贡献,并且未来节水灌溉的发展方向应该是区域化、智能化、精准化。

In order to explore the current research trends and hot spots of water-saving irrigation at home and abroad,based on CNKI and WOS core database,this paper retrieved the scientific and technological literature on water-saving irrigation from 2002 to 2021,and used VOSviewer visual analysis software and database analysis results to analyze the annual publication volume,publication countries and institutions,publication journals,high-yield authors and highly cited literature,and research topics and keywords.The results showed that from 2002 to 2021,the annual publication volume of CNKI database fluctuated greatly,while that of WOS database was on the rise,among which Chinese scientific research institutions had become the main force of published papers in WOS database.The literature in this field was mainly published in journals such as′water-saving irrigation′,′rural water conservancy and hydropower in China′,′Journal of Irrigation and Drainage′,and′Agricultural Water Management′,among which′water-saving irrigation′had the highest number of publications(752).The author with the highest number of articles published in the CNKI database in this field is Professor Peng Shizhang of Hohai University,with 42 articles published,while the author with the highest number of articles published in WOS database is Professor Dukes Michael D of the University of Florida,with 28 articles published.The research direction in this field mainly focused on irrigation methods,irrigation systems,water use efficiency and so on.Water-saving irrigation research in the future is still a hot issue,Chinese scientific research workers in this field have significant contributions,and the future development direction of water-saving irrigation should be regionalization,intellectualization and precision.
