Research Progress on Gully Erosion Monitoring Techniques and Methods from 1993 to 2022——A Bibliometric Analysis Based on CiteSpace
[Objective]In order to provide references for promoting the development of breakthrough research methods and techniques for monitoring of gully erosion,the status quo,progress,and trends of the research technologies and methods for monitoring of gully erosion in the world from 1993 to 2022 were analysed and the development trend of the research technologies and methods were summarised.[Methods]A total of 376 English language research articles from the Web of Science were selected via a bibliometric approach using the CiteSpace software for knowledge map analysis.[Results]① Research on gully erosion shows an upward trend during 1993-2022,with a rapid development after 2013,especially in 2020(47 articles).② China(20.25％)and the United States(10.44％)had the highest publication outputs among the main research countries.In terms of the citation frequency,the United Kingdom(70.85 times)and Belgium(72.89 times)had the highest citation frequencies.Among the top 10 influential research institutions in this field,there were four institutions from China(Chinese Academy of Sciences,Beijing Normal University,Northwest University of Agriculture and Forestry,and China West Normal University).The most influential author is Poesen Jean,with only one Chinese scholar in the top 10 in terms of publications.③ Co-occurrence of keywords indicated that current research on gully erosion mainly focus on the spatiotemporal distribution and changes,influencing factors,and mechanisms of gully erosion.The diversity of techniques and methods had been gradually increasing,with 2D plane measurements being replaced by 3D volumetric measurements,and the integration of multi-technology had become a new trend in the field of gully erosion.[Conclusion]The development of techniques and methods for the study of gully erosion has a bright future,emphasizing the combined use of a variety of techniques to improve the accuracy of the measurements,which is conducive to the development of the discipline.
