基于文献计量分析的近30年国内外盐碱地研究进展

Research Progress of Saline-alkali Land at Home and Abroad over the Past 30 Years Based on Bibliometric Analysis

[目的]为全面了解盐碱地领域研究发展现状和未来研究趋势。[方法]利用Web of Science的核心合集数据库文献检索功能,结合HiteSpace和VOSviewer等文献可视化分析软件,系统总结并分析了盐碱地领域研究的发文量、关键词、国家、机构、作者等。[结果]盐碱地领域研究正处于快速发展阶段,总发文量呈二次函数形式增长;发文量最多的国家是中国,发文量最多的研究机构是中国科学院,发文量最多的作者是中国科学院新疆生态与地理研究所李彦,发文量最多的期刊为《Agricultural Water Management》。中国和美国、澳大利亚等国有密切合作关系,中国科学院与发文量较多的几个研究机构均有密切关系。盐碱地领域研究主要集中在植物对盐胁迫响应、农田水肥管理、土壤改良、土壤微生物等方面。未来研究热点可能集中在农业水资源可持续利用和土壤微生物多样性2方面。[结论]该研究有助于研究者了解盐碱地领域研究现状及未来研究热点。

[Objective]To fully understand and analyze the present situation and future research trend of saline-alkali land research.[Method]We made use of the literature retrieval function of Web of Science core collection database,combined with HiteSpace and VOSviewer and other literature visualization analysis software,systematically summarizes and analyzes the number of papers,keywords,countries,institutions,authors and so on.[Result]The research in the field of saline-alkali land was in the stage of rapid development,and the total number of articles published was increasing in the form of quadratic function;the country with the largest number of articles was China,the research institution with the largest volume of publication was the Chinese Academy of Sciences,the author with the largest volume of publication is Li Yan of Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences,and the journal with the largest volume of publication was Agricultural Water Management.China had close cooperative relations with the United States,Australia and other countries,the Chinese Academy of Sciences had a close relationship with several research institutions with a large number of papersthe research in the field of saline-alkali land was mainly focused on the response of plants to salt stress,farmland water and fertilizer management,soil improvement,soil microorganisms and so on.The future research hotspots might focus on sustainable utilization of agricultural water resources and soil microbial diversity.[Conclusion]This research is helpful for researchers to understand the current research situation and future research hotspots in the field of saline-alkali land.
