基于CNKI和WOS数据库的盐碱地研究进展文献计量分析

Bibliometric analysis of research progress on saline alkali land based on CNKI and WOS databases

为全面了解当前国内外盐碱地领域的研究进展,基于中国知网(CNKI)数据库和Web of Science(WOS)全文数据库,对2012—2021年盐碱地相关领域的文献进行检索,从国家、年发文量、发文期刊、高被引论文、资助基金和研究机构等方面进行分析。结果表明:国内外盐碱地相关领域的文献量均呈增长趋势,且中文发文量高于英文;国内外研究方向和学科有交叉重叠部分,但也有一定的差别;研究论文主要发表在《农业工程学报》《干旱地区农业研究》等中文期刊和Science of the Total Environment,Environmental Earth Sciences等英文期刊。中国在发文量、发文机构和基金资助项目等方面远超国外,但在文章引用次数、国际影响力稍落后于其他国家;国内研究热点在盐碱土的改良及环境材料的开发上,国际上较多关注在盐碱地治理、植物生长效应、物种多样性及次生盐碱化等方面。因此,应开展适应性强的盐碱土壤改良技术(研发环境友好的去盐材料)并探讨盐碱地农业可持续发展策略,以更好应对盐碱地治理面临的难题。

In order to comprehensively understant the current research progress in the field of saline alkali land at home and abroad,the literature related to saline alkali land published from 2012 to 2021 was searched based on the CNKI database and the Web of Science(WOS)full-text database in this study.The literature obtained are analyzed from six aspects such as country,annual number of publications,publishing journals,highly cited papers,funding sources,and research institutions.The results show that:The number of documents related to saline-alkali land research at home and abroad showed an increasing trend,and the number of articles in Chinese was higher than that in English.There were overlapping in research directions and disciplines at home and abroad,but there were also some differences.The research papers were published in Chinese journals such as Journal of Agricultural Engineering and Agricultural Research in Arid Regions,and in English journals such as Science of The Total Environment and Environmental Earth Sciences.China was far ahead of other countries in terms of the number of articles published,the number of institutions that publish articles,and the number of projects funded by foundations.However,China lagged slightly behind other countries in terms of the number of citations and the international influence of articles.Domestic research hotspots focused on the improvement of saline soils and the development of environmental materials,while more international attention was paid to saline land management,plant growth effects,species diversity and secondary salinization.Therefore,the development of adaptable saline soil improvement technologies(research and development of environmentally friendly saline materials)and the exploration of strategies for the sustainable development of saline-alkaline agriculture should be pursued in order to address the challenges of saline-alkaline land management.
