土壤侵蚀是导致水土流失、土地退化和生态系统脆弱等问题的重要因素，径流小区尺度的土壤侵蚀研究有助于深入理解侵蚀机制并制定防治策略。使用CiteSpace软件对1992—2023年间Web of Science数据库收录的径流小区土壤侵蚀研究文献进行了文献计量分析。通过对4 313篇文献的系统研究，分析了土壤侵蚀研究的主要研究机构及作者的合作与贡献情况、关键词共现以及研究热点的转移。结果显示：全球范围内该领域的发文量呈增长趋势，出现了“气候变化”“土地利用”和“黄土高原”等热点话题，美国和中国是发文量最大的国家，其中美国与欧洲国家和机构合作程度较高；研究热点从传统的侵蚀机理和监测预防转向气候变化、土地利用与遥感技术的综合应用；关键词共现与时区分析揭示了生态系统服务和可持续土地管理策略的重要性日益增加。未来关于跨尺度研究和技术应用，特别是在生态系统服务领域和遥感技术与GIS的应用方面将是研究的重点，同时也需要关注土壤侵蚀测量方法的准确性和实用性，以及全球合作在解决土壤侵蚀问题中的重要性。
英文摘要:
Soil erosion is a significant factor contributing to soil and water loss, land degradation and ecosystem fragility. Research on soil erosion at the runoff plot scale is instrumental in deepening the understanding of erosion mechanisms and formulating prevention strategies. By means of CiteSpace, we conducted a bibliometric analysis on the studies of soil erosion in runoff plots indexed in the Web of Science database from 1992 to 2023. A systematic examination of 4, 313 documents was performed to analyze the collaborations and contributions of major research institutions and authors, keyword co-occurrences, and shifts in research hotspots. The results indicate a growing trend in publication volume within this field globally, with hot topics including "climate change" "land use", and "Loess Plateau". The United States and China possess the highest publication volumes, with the United States showing significant cooperation with European countries and institutions. Furthermore, research hotspots have shifted from conventional erosion mechanisms, monitoring and prevention to integrated applications of climate change, land use and remote sensing technologies. Additionally, keyword co-occurrences and time zone analyses have revealed the increasing importance of ecosystem services and sustainable land management strategies. Future research should focus on cross-scale studies and technological applications, particularly in the fields of ecosystem services, and the use of remote sensing technologies and GIS. Attention must also be paid to the accuracy and practicality of soil erosion measurement methods, as well as the significance of global cooperation in addressing soil erosion issues.
