基于CiteSpace的论文题录分析与学科布局研究——以农业遥感技术为例

Analysis of Topic Catalogue and Study of Subject Layout Based on CiteSpace,Taking Agricultural Remote Sensing Technology as an Example

【目的】文章以农业遥感技术为例,研究国际农业遥感领域近10 年的科研论文题录数据,阐述国际农业遥感领域的研究前沿与热点,为北京农业信息技术研究中心的遥感学科布局发展提供精准服务。【方法】从情报学的角度,利用CiteSpace 可视化知识图谱工具,对Web of Science 数据库近10 年的农业遥感论文题录数据,分别从时间序列、国别、机构、作者和关键词5 个角度进行了统计分析。【结果】从时间分布上,农业遥感领域发表数量逐年稳步提升,农业遥感技术开发势头向好;从国别上,美国是研究热度最高的国家,其发表论文数量最多,论文被引用频次最高;从机构和作者上,中国近几年发展迅猛,其众多科研单位与科研人员在国际农业遥感领域作用十分突出;从关键词上,传统的遥感平台开发和农业遥感应用是农业遥感的出发点与根本目标。【结论】中国在农业遥感领域后起直追,相关论文数量和质量大幅提高,但同起步较早的美国和欧盟国家相比,仍有较大差距,基于研究结果,为北京农业信息技术研究中心遥感学科方向布局和热点跟踪提供情报参考,有效提升其在该领域的科技竞争力。

[Purpose] Taking agricultural remote sensing technology as an example, the catalogue data of scientific papers in the field of international agricultural remote sensing in recent 10 years was studied in the paper. The research frontiers and hotspots in the field of international agricultural remote sensing were expounded, which will provide precise services for the development of remote sensing discipline layout of Beijing Agricultural Information Technology Research Center.[Method] From the perspective of information science, using CiteSpace visual knowledge atlas tool, statistical analysis was made from five perspectives of time series, country, institution, author and key words with the title data of agricultural remote sensing papers in Web of Science database in recent 10 years.[Result] In terms of time distribution, the number of agricultural remote sensing publications has steadily increased year by year, and the momentum of agricultural remote sensing technology development has been good. Nationally, the United States has the highest research enthusiasm, with the largest number of published papers and the highest citation frequency. In terms of institutions and authors, China has developed rapidly in recent years, and many scientific research institutions and researchers have played a prominent role in the field of international agricultural remote sensing. In terms of keywords, the development of traditional remote sensing platform and the application of remote sensing in agriculture are still the starting point and fundamental purpose of agricultural remote sensing.[Conclusion] China has been following up in the field of agricultural remote sensing, and the quantity and quality of related papers have been greatly improved, but there is still a big gap compared with the United States and European Union countries which started earlier. Based on the research results, this paper provides information reference for the orientation and hot spot tracking of remote sensing disciplines in our unit, which will effectively enhance the scientific and technological competitiveness of our unit in this field.
