摘要
以中国期刊全文数据库CNKI收录的关于粮食安全的高水平文献为研究对象,运用统计学和文献计量学的方法,分别对其进行数据、著者,期刊和主题分析。分析发现,我国在该领域的研究人员研究水平呈阶梯式分布,高水平研究人员匮乏;目前我国在该领域的科研水平整体偏低。运用SAS统计软件和线性回归分析法建立模型对我国粮食安全文献数量的发展进行预测,提出需加大对粮食安全领域研究人员科研支持力度的建议。
By taking the number of high quality articles published in food security collected in CNKI as the research object,this paper has used bibliometircs to implement data,author,periodical and subject analysis.We found that the researchers engaged in this domain in China have a staircase distribution and there is a lack of high-level research staff.At present,the research level of researchers engaged i-n this domain is general low.This paper has forecasted the development of the number of articles in food security in China through statistic software of establishing models and put forward suggestions that it is essential to strengthen efforts supporting research projects of researchers engaged in food security.
