基于文献计量的锑对农作物影响研究趋势

为了明确锑对农作物影响领域的研究现状和发展趋势，基于Web of Science数据库，检索了1991~2021年该领域的文献，利用文献计量学软件CiteSpace对年发文量、发文国家/地区、研究机构以及关键词共现网络、突显关键词、文献共被引网络和关键文献进行了可视化分析，并总结了未来研究发展趋势.结果显示：1991~2021年，本研究领域发文量整体呈快速增长模式，中国、美国、巴西、印度、意大利、西班牙等发文量较多，是推动该领域发展的主要国家.中国科学院和中国农业科学院是全球发文数量排名前10的中国研究机构，占总发文量的10.5%.基于关键词共现网络及突显词分析，锑对农作物的影响研究从主要考虑农作物生长、产量和品质的影响研究发展到考虑土壤、作物、水体、沉积物等环境中锑的迁移转化机制研究，土壤微生物群落活性的响应机理以及锑对人类健康的风险评价研究成为近年来的研究热点.

Research trends in effects of antimony on crops based on bibliometrics

In order to clarify the research status and development trends on effects of antimony on crops, the literature research was conducted in this field from 1991 to 2021 based on the database of Web of Science. The annual number of published literatures, the published number of main countries or regions, research institutions, keyword co-occurrence network, prominent keyword analysis, the co-citation network and key literatures were visually analyzed. Then, the future research development trend was summarized. Results showed that the total number of published literatures issued in this research field had shown a rapid growth trend during the period from 1991 to 2021. China, United States, Brazil, India, Italy, Spain and other countries, which were the main countries promoting this field development, published a large number of relevant literatures. The Chinese Academy of Sciences and the Chinese Academy of Agricultural Sciences were two Chinese research institutions among the top ten institutions in the number of publications, accounting for 10.5% of total amount. Based on the analysis of keyword co-occurrence network and keywords with the strongest citation bursts, the research hotspots on the impact of antimony on crops had developed from the impact of Sb on crop growth, yield and quality to the migration and transformation mechanism of Sb in soil, water, crops, sediments and other environments. The response mechanism of microbial community activity in soil and the risk assessment of antimony on human health had become research hotspots in recent years.
