    摘要:

    【背景】磷转化微生物对于自然环境中的磷循环具有重要作用。此类微生物通过对环境中磷素的溶解矿化和吸收转运等作用促进资源高效利用,减少环境污染,对粮食安全和生态系统稳定也具有积极的影响。【目的】探究近年来国内外关于磷转化微生物的发展热点及趋势,展示该领域的知识结构和知识演化过程,为后续研究提供可行性的参考和启示。【方法】应用CiteSpace可视化软件对2002-2022年发表在中国知网(CNKI)和Web of Science (WOS)数据库中的文献通过关键词共现分析、关键词聚类分析、关键词突现分析、发文数量分析、国家分布、作者合作共现及机构合作共现等方式对磷转化微生物的研究现状及新兴趋势进行分析。【结果】最终共筛选出887篇有效文献。磷转化微生物研究在2016年后开始蓬勃发展,近几年增速加快;中国和美国学者是此领域重要的研究力量;中国是发文量最多的国家,中国科学院是发文量最多的机构;热门的研究领域为菌株的分类与筛选、代谢途径、营养元素循环以及环境污染与生态保护。【结论】磷转化微生物具有广阔的发展前景。目前,生物炭及磷转化微生物的响应机制正在成为新的研究热点。此类技术在未来的广泛应用是必然的发展方向。本文以可视化的方式阐释了磷转化微生物研究发展态势,提出了未来重点研究方向,为农业生产与可持续发展提供了重要的理论基础。

    Abstract:

    [Background] Phosphorus-transforming microorganisms play an important role in the phosphorus cycle in the natural environment. These microorganisms promote the efficient resource utilization, reduce environmental pollution, and have positive impacts on food security and ecosystem stability by dissolving, mineralizing, absorbing, and transporting phosphorus in the environment. [Objective] To explore the research hotspots and trends of phosphorus- transforming microorganisms both domestically and internationally in recent years, visualize the knowledge structure and evolution process in this field, and provide feasible references and insights for subsequent research. [Methods] We retrieved the articles in this field published by China National Knowledge Infrastructure (CNKI) and Web of Science core collection (WOS) from 2002 to 2022. CiteSpace was employed to analyze the keyword co-occurrence, keyword clustering, bursts, number of publications, country distribution, author cooperation, and institution collaboration. [Results] A total of 887 valid articles were ultimately screened out. The research on phosphorus-transforming microorganisms began to flourish after 2016 and experienced accelerated growth in recent years. China and the United States were leaders in this field. China was the country with the largest number of publications, and the Chinese Academy of Sciences was the institution with the largest number of publications. The research hotspots included the classification and screening of strains, metabolic pathways, nutrient cycling, environmental pollution, and ecological protection. [Conclusion] Phosphorus-transforming microorganisms have broad development prospects. The mechanism of phosphorus- transforming microorganisms in response to biochar is becoming a new research hotspot. The wide application of such technologies in the future is an inevitable development trend. This article provides a visual explanation of the research and development trend of phosphorus-transforming microorganisms, proposes future key research directions, and provides a theoretical basis for agricultural production and sustainable development.
