摘要：為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。

Abstract：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，whats 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 selenium- enriched crops. In general，the number of SCI papers on selenium-enriched crops research has increased yearby 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.

0引言

作为人体的必需微量元素，硒元素对人体的健康具有重要意义，尤其在甲状腺激素的转化、预防和减少心血管疾病、降低各种癌症风险等方面起重要作用[1]。人体摄入硒过量和缺乏都易诱发各种疾病，如硒过量易引起脱发脱甲和神经系统疾病[2-3]，硒缺乏易患克山病和大骨节病[4-5]。目前，尚未证实硒元素对作物的必需性，但适宜浓度的硒对蔬菜、果树和谷类有积极效应，经过硒生物强化的蔬菜、水果和谷类是人体补硒的有效途径[6]。……
