摘　　要：为分析无人机技术应用于土壤侵蚀研究的热点主题和发展趋势,以Web of Science核心数据库和中国知网为文献来源,使用CiteSpace、Scimago Graphica和ArcGIS生成可视化图谱,对871篇中英文文献进行文献计量分析。结果表明:无人机在土壤侵蚀研究中的应用总体呈增长态势,其中欧洲国家具有先发优势,学术影响力大,中国在国外研究的基础上发展创新,学术力量处在上升期;国内外学者主要围绕无人机摄影测量技术和土壤侵蚀机理过程2方面开展研究,集中在无人机及多源遥感数据的获取与融合、无人机侵蚀监测与信息提取算法、基于无人机遥感的水文泥沙连通性与土壤侵蚀模型、无人机侵蚀灾变调查防治与水土保持综合治理4个方向。根据国内外研究现状,建议深入研究无人机遥感内业处理算法和精度提高方法,加强多源多尺度数据融合,进而以高精度数据为基础,识别影响侵蚀的关键要素,明确侵蚀及其灾变的机理过程,科学指导新时代水土保持工作。Soil erosion is a major global environmental concern.Safeguarding soil and water resources requires a comprehensive understanding of erosion processes to proactively address and manage soil erosion.Accurately identifying key erosion features and implementing targeted soil and water conservation efforts are therefore imperative.Unmanned Aerial Vehicle(UAV)remote-sensing technology offers a novel method for advancing soil erosion research.As UAV applications in this field continue to progress,it is essential to systematically review and compare recent developments in soil erosion research between China and other countries so as to anticipate future research directions.In this study,we used the CiteSpace software to perform a bibliometric analysis of 871 Chinese and English articles published from 2008 to 2022 that were indexed in the Web of Science core database and China National Knowledge Infrastructure.Using statistical data from these publication databases,CiteSpace,Scimago Graphica,and ArcGIS,visual network maps were generated to summarize the fundamental characteristics and research hotspots related to UAV use in soil erosion research.The results indicate that the overall trend of UAV use in soil erosion studies is increasing.Countries such as the UK,France,Italy,Germany,and Australia have taken the lead,resulting in significant academic influences.Chinese researchers have built on mature research conducted abroad and are actively innovating,resulting in more publications and a growing academic impact.Globally,soil erosion research has predominantly focused on UAV photogrammetric technology and soil erosion mechanisms.Global research hotspots include the acquisition and integration of UAV and multi-source remote sensing data in erosion studies,innovative improvements in UAV-based erosion monitoring and information extraction algorithms,hydrological sediment connectivity and soil erosion model construction using UAV data as a source,and improvements to erosion disaster investigation,prevention,and comprehensiv
