基于文献计量方法的农业地理信息进展研究

A bibliometric analysis about research trends of agro-geoinformatics

本文采用文献计量和知识图谱可视化的方法,对SCI和SCIE中有关农业地理信息的论文进行定量统计和定性分析。自1991-2015年共有15127篇有关农业地理信息的文章发表。以"Agro-geoinformatics"为检索关键词,从文章发表数量、地理分布、国际之间合作以及关键词等方面进行统计分析,解释了农业地理信息在过去25年的发展特点和发展趋势。研究表明:(1)农业地理信息的相关研究一直呈增长的趋势,在近年来,增长更为显著。(2)研究贡献最多的机构是中国科学院,贡献最多的国家是美国。(3)关键词分析中以"遥感"、"GIS"、"精准农业"、"土壤湿度"等关键词近年来的迅速增长代表了农业地理信息的研究热点。

A bibliometric analysis was conducted to evaluate agro- geoinformatics research from different perspectives during 1991- 2015 based on the SCIE and SSCI databases. According to 15, 127 document samples related to agro-geoinformatics, the bibliometric analysis was firstly identified by general patterns for publication outputs. Then it evaluated productivity and performance in the level of author＇s country, and revealed the characteristics of authors＂ geographic distributions and international collaborations. What＇s more, it analyzed temporal trends in keywords usage in agro- geoinformatics studies, agro-geoinformatics-related research has undergone notable growth during the past 25 years. And a keyword analysis has found that effective research technologies and methods were promising topics attracting the most attention during the study period. Several keywords, such as ＂remote sensing＂, ＂GIS＂, ＂Precision agriculture＂, ＂soil moisture＂and ＂NDVI＂have received dramatically increasing attention during the study period, which is possibly signaling the future research trends.
