摘要
【目的】了解盐碱土壤微生物领域的研究现状、热点及发展趋势。【方法】采用文献计量学方法,利用可视化分析工具VOSviewer和CiteSpace,对2004—2024年中国知网(652篇)和WOS核心库(982篇)盐碱地微生物领域文献进行系统分析。【结果】盐碱地微生物相关研究领域的年发文量总体呈上升趋势,英文文献年均发表量高于中文文献;中国在该领域累计发文1103篇,位居全球前列,并与加拿大、英国等26个国家建立了科研合作关系。由关键词聚类分析可知,研究热点主要集中在不同盐碱土壤微生物群落特征及主要环境驱动因子、植物与微生物的互作机理及其生态功能、耐盐促生微生物资源的筛选与盐碱地生物修复机制。盐碱地微生物研究经历了从早期(2004—2015年)物种鉴定与基础改良,到中期(2016—2020年)群落生态与功能探索,直至近期(2021—2024年)国内外共同聚焦“微生物-土壤-植物”系统互作与调控的演进过程,显示出明显阶段性与融合性。【结论】未来该领域将依赖广泛的国际合作与深度的学科交叉,融合多组学、大数据与人工智能,系统揭示微生物群落组装与功能调控机制,推动微生物精准调控、功能菌株开发及微生物组修复等方向的突破,为盐碱土治理与农业可持续发展提供绿色解决方案,并成为应对全球生态与粮食安全挑战的关键推动力。
【Background and Objective】Soil salinization is a major constraint to sustainable agricultural production,and amending such soils with salt-tolerant microorganisms has been found to be effective in improving soil quality and enhancing crop tolerance to water and salinity stress.This paper analyzes international research in this area.【Method】Bibliometric analysis was conducted using VOSviewer and CiteSpace to systematically examine publications from 2004 to 2024 on saline-alkali soil microbiology retrieved from the China National Knowledge Infrastructure(CNKI,652 articles)and the Web of Science Core Collection(WOS,982 articles).【Result】Annual publications in saline–alkali soil microbiology showed a substantial increase during this period,with publications in English journals consistently and markedly overshadowing those in Chinese journals.China led the world,publishing 1103 papers and collaborating with 26 countries,including Canada and the United Kingdom.Keyword clustering analysis showed that research hotspots in this field were:①microbial community structure and its environmental drivers;②mechanisms underlying plant-microbe interactions and their ecological functions;and③screening of salt-tolerant and growth-promoting microorganisms,as well as the mechanisms underlying biological remediation of saline-alkali soils.From 2004 to 2024,research on microbiology in saline-alkali soil can be divided into three stages:an early stage(2004—2015)emphasizing species identification and soil improvement;a middle stage(2016—2020)focusing on microbial community ecology and functional characterization;and the most recent stage(2021—2024)characterized by increased attention to the regulation of the microbe-soil-plant system.【Conclusion】Future research in saline-alkali soil microbiology will depend on international collaboration and interdisciplinary cooperation.Advances in multi-omics approaches,big data and artificial intelligence will enable systematic elucidation of microbial community assembly and functional regulation mechanisms,which will promote precision microbial management,functional strain development,and microbiome restoration.These advances will provide environmentally friendly solutions for remediating saline-alkali soils and sustaining agricultural production to meet the growing demand for food.
