土壤遗留效应是介导植物群落和土壤特性之间相互作用的重要机制，不仅影响着植物群落动态和物种共存，同时在土地利用和管理方面也发挥着重要作用。本文基于Web of Science数据库中检索到的2000～2022年发表的相关文献进行计量学分析，探讨此研究领域的研究现状以及热点问题。结果表明:土壤遗留效应的发文量总体呈现上升趋势，美国农业部是发文量最多的机构(646篇)，以中国科学院为代表的国内科研机构对该领域的发展也做出了积极贡献;生态学、环境科学、土壤学和植物学是该领域的主要发文学科，这些学科的交叉合作对深入了解土壤遗留效应起着关键作用;在国际合作方面，该领域已显示出全球交流和联系日益密切的趋势，但考虑到地理位置等因素，未来各研究团队仍需保持密切合作，共同加强该领域高水平、高认可度研究成果的产出;目前，该领域的热点问题集中在土壤遗留效应对土壤微生物群落、农业土地管理和不同生态系统恢复的影响，以及气候因素在驱动遗留效应中的作用。未来的研究可以进一步探讨这些问题，并结合新兴技术手段，如遥感技术、GIS技术和模型模拟等，推动土壤遗留效应的定量评估和预测，为实现可持续土地管理和生态系统发展提供支撑。
Mapping the Landscape of Soil Legacy Effect Research:A Bibliometric Analysis
The soil legacy effect,a crucial mechanism mediating plant-soil interactions,significantly impacts plant community dynamics,species coexistence,and land use management.This study employed a bibliometric analysis of relevant literature from the Web of Science database(2000-2022)to examine cur-rent research trends and identify key areas of investigation in this field.By synthesizing existing literature,we aimed to provide valuable insights into the soil legacy effect and its implications for ecological processes and sustainable land management.The results showed a rising trend in soil legacy effect publications.The United States Department of Agriculture(USDA)led with 646 publications,followed by significant contri-butions from domestic institutions like the Chinese Academy of Sciences.Disciplines such as ecology,envi-ronmental science,soil science,and botany emerged as the major contributors,reflecting their central role in studying the phenomenon.Collaborative efforts between these disciplines had been instrumental in advancing our understanding of the soil legacy effect.International collaboration showed a positive trend,highlighting increasing global connections.However,factors like geographical proximity may necessitate closer cooperation among research teams to generate high-impact research.Current research hotspots include the influence of soil legacy effect on soil microbial communities,agricultural practices,and restora-tion of diverse ecosystems.Understanding the role of climate factors is another prominent area of study.Future research should delve deeper into these areas by integrating emerging technologies such as remote sensing,Geographic Information System(GIS),and model simulations.These advancements can facili-tate quantitative assessment and prediction of soil legacy effects,ultimately supporting sustainable land management and ecosystem development.
