基于文献计量分析我国无人机氮素营养诊断研究现状
|
摘要
为了解我国无人机在氮素营养诊断方面的研究现状和发展趋势,为相关领域的研究人员更好地掌握该领域的发展态势和研究热点提供知识服务。本文以"无人机"+"氮素营养"为主题词在《中国期刊全文数据库》中检索相关文献,采用文献计量学方法,从年度载文量与期刊分布、核心作者群及主要产出机构、基金项目、硕博论文、下载量及被引频次等方面对2008-2017年我国"无人机氮素营养诊断"文献进行统计。结果表明:2008-2017年检索到71篇文章,发文量及发文期刊数总体呈上升趋势,平均每年发表6.45篇,文献主要分布在32种科技期刊上,发文量最高的是中国农业大学的杨贵军和沈阳农业大学的于丰华,均为3篇,普赖斯发文篇数为1.30篇。西北农林科技大学(7篇)、中国农业科学院(4篇)、浙江大学(4篇)、中国农业大学(3篇)、沈阳农业大学(2篇)、南京农业大学(2篇)是该领域研究的核心研究机构。
In order to understand the research status and development trend of UAV in nitrogen nutrition diagnosis in China,and to provide knowledge services for researchers in related fields to better grasp the development trend and research hotspots in this field.In this paper,with the theme of‘UAV'+ ‘Nitrogen Nutrition',relevant literatures were retrieved in"China Journal Full-Text Database".Using bibliometric method,the annual papers and journal distribution,core author groups and major output institutions,fund projects,rich papers,downloads and citations were analyzed from 2008 to 2017.The literature of‘nitrogen nutrition diagnosis of UAV'in China was analyzed in 1997.The results showed that 71 articles were retrieved from 2008 to 2017.The average number of articles published and journals published was 6.45 per year.Documents were mainly distributed in 32 scientific and technological journals.The highest number of articles published was Yang Guijun of China Agricultural University and Yu Fenghua of Shenyang Agricultural University,which were 3articles,and Price's was 1.30 articles.Northwest Agricultural and Forestry University(7articles),Chinese Academy of Agricultural Sciences(4articles),Zhejiang University(4articles),China Agricultural University(3articles),Shenyang Agricultural University(2articles),Nanjing Agricultural University(2articles)are the core research institutions in this field.
