摘要: 基于科学知识图谱的方法与知识可视化的理论,以CNKI数据库中收录的1997—2016 年20 年间遥感在农业领域研究的文献数据为切入点,探索20 年来遥感在农业领域研究的热点和趋势。通过对具体的机构合作图谱、聚类图谱和关键词图谱进行分析解读,直观展现了该领域正处于快速发展阶段,研究机构差异显著、热点主题明确。通过机构合作分析发现遥感在农业领域研究中中国科学院的发文量居于首位;通过关键词共现分析,探究该领域的研究热点集中在农用地变化和遥感监测以及精准农业形成的3 个大的聚类;最后通过突现检测分析得出,遥感技术和地理信息系统技术在土地利用、核农学和生物科学等领域的运用将成为很长一段时间的发展趋势。

Abstract: Based on the method of scientific knowledge map and the theory of knowledge visualization, the authors explored the hotspots and trends of remote sensing research in agriculture in the past 20 years based on literatures of remote sensing research in agriculture in CNKI database from 1997 to 2016. Through the analysis of cooperation map, cluster map and key words map of specific institutions, the results showed that this research field was in a rapid development stage, the research institutions were significantly different and had clear hot topics. Through the analysis of institutional cooperation, it was found that the published paper number of CAS was the most, and key words analysis showed that the research focused on agricultural land change, remote sensing monitoring and precision agriculture. Finally, the application of remote sensing technology and geographic information system technology in land use, nuclear agronomy and bioscience would be the trend of the development in a long period of time.
