摘　　要：基于农业科技创新的发展需求,为农业科技资源的有效配置提供支撑,从文献计量角度对全球植物科学领域研究现状及态势进行分析。利用定性、定量相结合的方法构建检索策略,基于Web of Science数据库及文献计量分析工具,对文献发表量、文献主要贡献国家、机构、期刊及发文量较高的作者H指数进行统计分析。结果表明,1995—2018年植物科学领域的文章发表量整体上呈现稳定增长趋势,学科呈现蓬勃发展的整体势头。美国和中国是文献主要贡献国家,文献量和总被引频次显著高于其他国家,但美国及欧洲国家的篇均被引数量高于中国。从全球来看,中国科研机构在发文数量占有绝对优势,而德国马克思普朗克的文章篇均被引数量高,达到10以上。对2016—2018年的高被引文献(Top10)进行内容分析,并通过高频词共现主题聚类可视化分析。从论文影响力及主题词规模2个维度表征领域内研究方向。结果表明,"植物应对生物及非生物胁迫"、"基因编辑技术"、"基因组学分析"、"植物生殖发育调控"是近年来植物科学的高关注度研究方向,主题内容与前期的需求调研相符,初步预测这些研究方向将对农业创新发展起到重要推动作用。Based on the needs of agricultural science and technology innovation,to provide support and refence for the effective allocation of agricultural science and technology resources,the research analyzed the current status and trend of global plant science research from the perspective of bibliometrics. Using a combination of qualitative and quantitative methods to construct a search strategy,based on the Web of Science database and bibliometric analysis tools,bibliometrics analysis was carried out on the number of articles published,the countries,institutions,journals,and authors influence with high publication numbers.The main results indicate that the number of articles published from 1995 to 2018 shows a steady growth trend as a whole. The United States and China are main contributors to the articles,but the number of citations per article contributed by the United States and European countries is higher than that of China. Chinese scientific research institutions have an advantage in the number of articles,while German Max Planck features highly the number of citations per article. The content analysis was carried out on Top10 articles with high citations published from 2016 to 2018,and the visual analysis of the topic clustering of high-frequency word cooccurrence was conducted. The results show that ’plants respond to biotic and abiotic stress’,’gene editing technology’,’genomic analysis’,’ plant reproductive development regulation’ are important research directions that have been given growing attention in recent years. The subject content is in accordance with the preliminary needs research. The research proves that these research directions will play an important role in promoting the development of agricultural innovation.
