摘要：

【目的】明确21世纪以来国内外盐渍土改良领域的研究热点和发展趋势，为盐渍土改良深入研究提供参考。【方法】以Web of Science（WOS）核心合集及CNKI核心期刊论文为检索对象，采用 Excel 2007软件绘图及CiteSpace软件进行知识图谱分析，从文献的年发文量、发文作者、发文机构、关键词时间共现分析、突现词分析5个角度，对检索到的相关文献进行计量和可视化分析。【结果】中、外文文献发文量趋势：2003—2009年为缓慢发展阶段，2010—2016年为波动（显著）增长阶段，2017—2023年为快速发展阶段；主要发文作者分别为杨劲松、赵兰坡、姚荣江、孙兆军、王全九、KANG Yaohu、WAN Shuqin、QADIR M、GHEYI H R、MURTAZA G等，主要研究机构为中国科学院、埃及知识库、印度农业研究委员会、西班牙国家研究委员会、美国农业部；从关键词来看，研究热点为水盐运移及其调控机理、植物耐盐性研究、化学改良剂施用、盐碱障碍绿色消减、盐碱障碍生物或微生物修复等；主要突现词为生物炭、湿润锋、微生物菌群、植物生物刺激剂（PBs）、耐盐植物促生菌（PGPR）、耐盐土壤细菌。【结论】当前，国内外盐渍土改良研究已进入快速发展阶段。中国、美国是该领域的全球领军者，印度、澳大利亚的研究力量正在逐渐壮大。国内外研究主要围绕土壤碳固存、生物炭、微生物菌群、抗氧化酶、磷利用率、耐盐土壤细菌等，聚焦土壤养分运移、盐渍障碍消减、改良剂、微生物修复等。未来盐渍化驱动机制、植物根际促生菌、盐碱障碍微生物修复以及联合大数据技术协同监测分析等多手段协同改良可能成为研究热点。

Abstract:

【Objective】Clarify the research hotspots and development trends in the field of saline soil improvement domestically and internationally since the 21st century，to provide references for in-depth research on saline soil improvement.【Methods】Using the core collection of Web of Science （WOS） and CNKI databases as search objects，Excel 2007 software for drawing and CiteSpace software for knowledge graph analysis，the relevant literature was quantitatively and visually analyzed from five perspectives：annual publication volume，authors，publication institutions，keywords time co-occurrence analysis，and burst words analysis.【Results】The trend of domestic and international literature publication volume were：from 2003 to 2009 in slow growth stage，from 2010 to 2016 in fluctuating （significant） growth stage，and in rapid growth stage from 2017 to 2023. The main authors were YANG Jinsong，ZHAO Lanpo，YAO Rongjiang，SUN Zhaojun，WANG Quanjiu，KANG Yaohu，WAN Shuqin，QADIR M，GHEYI H R，MURTAZA G，et al. The main research institutions were Chinese Academy of Sciences，Egyptian Knowledge Bank，Indian Council of Agricultural Research，Spanish National Research Council，and U. S. Department of Agriculture. In terms of keywords analysis，the research hotspots were water and salt transport and the regulation mechanism，research on plant salt tolerance，the application of chemical amendments，green reduction of saline-alkali obstruction，and the biological and microbial remediation of saline-alkali obstruction. The main burst words were biochar，wet front，microbial community，plant biostimulant（PBs），plant growth-promoting rhizobacteria（PGPR），and salt-tolerant soil bacteria.【Conclusion】Currently，domestic and international research on saline soil improvement has entered the stage of rapid development. China and the United States were the global leaders. India and Australia were gradually strengthening their research capabilities. Domestic and international research were mainly focused on soil carbon sequestration，biochar，microbial community，antioxidant enzymes，Phosphate utilization，salt-tolerant soil bacteria，etc.，as well as soil nutrient movement，salt obstruction reduction，chemical amendments，microbial remediation and so on. In the future，salinization driving mechanism，plant growth-promoting rhizobacteria，microbial remediation of saline obstruction，and collaborative monitoring and analysis of big data technology may become research hotspots.
