基于文献计量学的中国作物富硒研究现状分析

Current Situation of Selenium-enriched Crops Research in China Based on Bibliometric

为全面了解中国作物富硒研究现状与发展趋势,采用文献计量学方法,对CNKI和SCI-E数据库收录的中国作物富硒研究文献进行统计分析。结果表明,1992—2020年中国作物富硒研究总发文量1085篇,年发文量总体呈上升趋势,2010—2020年发文量占67.0%,SCI文献逐年增多。华中农业大学、南京农业大学、西北农林科技大学、中国农业大学和中国农业科学院的科研实力和学术影响力较强。中国作物富硒研究主要集中在8个方面,包括硒对作物的生长、产量和品质的效应研究,作物对硒的吸收、转运及分配研究,硒对作物吸收镉、铅和汞等有害元素的拮抗作用研究,硒对作物的抗氧化效应研究,硒对作物光合特性效应研究,富硒作物的硒种类和含量研究,硒与锌、钼和硫等元素的相互作用研究,作物富硒效应的分子机制研究。中国作物富硒研究SCI文献逐年增多,学术影响力不断提升,中国作物富硒研究已由生理生化水平深入到分子生物学研究水平。

A bibliometric analysis was conducted to study the current situation and development trend of selenium-enriched crops research in China, the research papers were from CNKI and SCI-E database. The results show that 1085 papers were published from 1992 to 2020 and the annual quantity of papers published increased year by year, what’s more, 67.0% of the papers were published from 2010 to 2020, and the number of SCI papers increased year by year. The Huazhong Agricultural University, Nanjing Agricultural University,Northwest A & F University, China Agricultural University and Chinese Academy of Agricultural Sciences are the institutions which have strong scientific research strength and academic influence. The main research topics for selenium-enriched crops in China are from 8 aspects: the effects of selenium on growth, yield and quality of crops;selenium uptake, transport and distribution in crops;the antagonism of selenium to cadmium,lead and mercury and other toxic element in crops;the antioxidant activity of selenium in crops;the effects of selenium on photosynthesis in crops;selenium types and content in selenium-enriched crops;the interaction of selenium with zinc, molybdenum, sulfur and other elements and the molecular mechanisms of seleniumenriched crops. In general, the number of SCI papers on selenium-enriched crops research has increased year by year in China, and the academic influence of China is rising;the trend of research on selenium-enriched crops in China has shifted from the physiology and biochemitry to molecular biology.
