摘要
通过遥感技术对荒漠化进行监测和评估可以及时、准确掌握荒漠化土地的消长变化信息,为相关部门及时制定荒漠化防治方法和策略提供科学依据。利用R语言bibliometrix计量分析包、VOSviewer和CiteSpace可视化分析软件,针对遥感技术在荒漠化监测和评估领域应用的国际研究态势进行了分析。结果表明:(1)遥感技术在荒漠化监测与评估领域应用的发文量自2016年以来急剧增长,正处于快速发展阶段。(2)该领域是一个涉及多学科的交叉学科,近年来不断有学者引入新兴技术。(3)中国在该领域拥有较强的研究实力和人才基础,但是在国际学术影响力和国际合作方面仍有提升空间。(4)国内外在该领域的研究中均形成了一定的合作规模,但是跨机构、跨国家合作的潜力仍然巨大。在研究主题分析中发现,近年来该领域的文章大致可以划分为荒漠化的研究对象以及其土地状态、荒漠化的成因以及荒漠化修复、遥感数据的分析方法、与遥感相关卫星或数据平台4个方面。基于上述分析结果,本文对未来遥感技术在荒漠化监测和评估领域应用的发展提出了相关建议。
Monitoring and evaluating desertification using remote sensing technology allows for timely and accurate grasping of the growth and decline of desertification land,providing a scientific basis for relevant departments to formulate desertification control methods and strategies in a timely manner.This article utilizes the bibliometric 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.②This field is an interdisciplinary subject involving multiple disciplines.In recent years,scholars have continuously introduced emerging technologies.③China has strong research strength and talent base in this field,but there is still room for improvement in international academic influence and international cooperation.④Both 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 desertification,desertification restoration;analysis methods of remote sensing data,and satellites or data platforms related 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.
