摘要：

基于文献计量学及CiteSpace V分析,对Web of Science和CNKI数据库中根瘤菌固氮的文献数量、出版刊物、研究内容及热点等做深入分析,总结目前该领域研究的重点与薄弱点,以期为致力于作物根瘤菌固氮的科研工作者与决策者提供一定的参考。分析结果表明,自1980年至今,研究根瘤菌固氮相关论文整体呈波浪式上升趋势,根瘤菌逐渐成为研究热点。目前,国际上美国、法国和英国是该研究领域发文量和被引频次最多的3个国家,而国内发文机构则主要集中在农业发展水平较高、学术力量雄厚的省份,如北京、江苏、黑龙江等,其中,发文量最多的为中国农业科学院,且根瘤菌方面的研究文献主要发表在农业类的专业学术期刊中。CiteSpace V分析发现,近40年国内外根瘤菌固氮研究领域的高频关键词主要有大豆、共生固氮、紫花苜蓿等,新兴热点有分子对话、化学模拟、功能基因组等。基于以上分析,今后应加强国内外该领域高水平科研机构间的合作与交流,这将是提高科研成果产出水平的有效途径之一。此外,研究根瘤菌固氮的分子机理,选育高效根瘤菌固氮品种,加强根瘤菌剂的高效应用,优化施肥技术,创建最佳根瘤菌固氮体系,提高根瘤菌固氮效率已成为当前和今后根瘤菌固氮研究的重点和热点,这将为科研人员掌握该领域前沿问题及确定选题方向提供依据。

Abstract:

Based on bibliometrics and CiteSpace V analysis, the number of literatures, publications, research contents and hot spots of nitrogen fixation by rhizobia in Web of Science and CNKI database were analyzed in depth. The key points and weak points of current research on crop nitrogen fixation in rhizobia were summarized to provide reference for researchers and decision makers in the field. The results indicate that research papers on nitrogen fixation by rhizobia have showed a wavy rising trend since 1980. The United States of America, France and the United Kingdom are the top three countries with the largest number of publications and citation frequency in this field at present. In China, publishing organizations are mainly from the provinces (municipalities) with strong agricultural and academic strength, such as Beijing, Jiangsu, Heilongjiang, etc. The Chinese Academy of Agricultural Sciences has largest number of papers published in this field, and the research literature on rhizobia is mainly published in agricultural professional academic journals. CiteSpace V analysis shows that in recent 40 years, the high-frequency keywords in the field of nitrogen fixation by rhizobiua at home and abroad are soybean, symbiotic nitrogen fixation, alfalfa, etc. The emerging hot spots include molecular dialogue, chemical simulation, functional genomics, etc. Based on the above analysis, it is an effective way to improve the output level of scientific research results by strengthening the cooperation and exchange between high-level scientific research institutes at home and abroad in the future. In addition, current and future research in this field should focus on studying the molecular mechanism of nitrogen fixation by rhizobia, breeding high-efficiency varieties, strengthening the efficient application of rhizobia, optimizing fertilization technology, building the best system of nitrogen fixation by rhizobia and increasing its efficiency. The study will provide a basis for researchers to grasp the frontier issues and determine the direction of topic selection in this field.

Key words: nitrogen fixation, rhizobia, bibliometrics, publication tendency, hot spots
