摘　　要：沟蚀是土壤侵蚀的一种主要形式,立体摄影技术是能够对沟蚀形态特征进行实时测量的一种新兴技术。为揭示近几十年来该交叉领域的发展和演变趋势,笔者采用文献计量学方法,利用可视化软件CiteSpace和VOSviewer对Web of Science核心集数据库中相关文献的热点及其演化趋势进行计量分析。国内外学者对该交叉领域的关注度逐年增加,其中美国、中国在该领域进行了大量研究;基于文献耦合关系对相关文献进行国家、机构、作者间合作联结强度进行分析,发现虽然我国相较美国而言起步较晚,但是有着很大的发展潜力。“无人机”“数字高程模型”“摄影技术”等关键词的出现,反映出该研究领域对其技术应用方面的精化趋势。Gully erosion is one of the main forms of soil erosion.Stereo-photography is a new technology which can measure the characteristics of gully erosion in real time.In order to reveal the development and evolution trend of this cross-field in recent decades,by using the visualization software CiteSpace and VOSviewer,the method of bibliometrics was adopted to make the quantitative analysis on the hot-spots and evolution trends of related literature in the Web of Science core set database.Domestic and foreign scholars pay more attention to this cross-field year by year,in which the scholars of the United States and China have conducted a lot of research in this field.Based on the literature coupling relationship,it was analyzed the cooperation strength among countries,institutions and authors,and was found out that although China starts late compared with the United States,it has great development potential.The emergence of keywords such as“UAV”“digital elevation model”and“photography technology”reflects the trend of refining of the technology application in this research field.
