Analysis of the International Research Trend in the Application of Remote Sensing Technology for Desertification Monitoring and Assessment
Monitoring and evaluating desertification using remote sensing technology allows for timely and accu-rate grasping of the growth and decline of desertification land,providing a scientific basis for relevant depart-ments to formulate desertification control methods and strategies in a timely manner.This article utilizes the bib-liometric analysis package Bibliometrix in R language,as well as the visualization analysis software VOSviewer and CiteSpace,to analyze the international research trends in the application field of remote sensing technology for desertification monitoring and assessment.The results show that:①The number of publications in the field of desertification monitoring and assessment using remote sensing technology has increased dramatically since 2016,indicating that the field is in a stage of rapid development.② This field is an interdisciplinary subject in-volving multiple disciplines.In recent years,scholars have continuously introduced emerging technologies.③ China has strong research strength and talent base in this field,but there is still room for improvement in in-ternational academic influence and international cooperation.④ Both domestic and international research in this field have formed a certain scale of cooperation,but there is still great potential for cross-institutional and cross-national collaboration.In the analysis of research themes,it is found that articles in recent years can be roughly divided into four aspects:the research subjects and their land status of desertification;the causes of desertifica-tion,desertification restoration;analysis methods of remote sensing data,and satellites or data platforms relat-ed to remote sensing.Based on the above analysis results,this article puts forward relevant suggestions for the future development of remote sensing technology in the field of desertification monitoring and assessment.
