基于CNKI的我国小麦低温逆境研究文献计量分析

Bibliometric Analysis of the Researches on Wheat Low Temperature Stress in China Based on CNKI Database

低温逆境已成为限制我国小麦稳产丰产与优质的主要农业气象灾害之一。为掌握我国小麦低温逆境研究的现状,以中国知网(CNKI)数据库为数据源,采用文献计量学方法分析1979—2020年小麦低温逆境研究论文的发文数量、研究机构、发文作者、文献来源、被引频次、研究热点及资助基金等方面的情况。结果表明:自1979年以来,我国小麦低温逆境领域的发文数量整体呈上升趋势;以东北农业大学、西北农林科技大学等为代表的研究机构均致力于该领域的研究,但研究机构间的交流与合作还有待加强;高被引文献多发表于《作物学报》《麦类作物学报》等优质期刊;关键词共现和聚类分析表明,目前我国小麦低温逆境领域的研究主要集中在耐低温小麦新品种的培育、低温胁迫对小麦生长发育及产量与质量的影响、小麦低温逆境的分子生物学研究等方面;国家级基金是小麦低温逆境研究领域的主要资助来源。未来应加强研究机构之间的交流与合作,推进协同创新,同时加强小麦低温逆境栽培防控技术的研究,从而实现我国小麦生产的抗逆保产与提质减损。

Low temperature stress has become one of the main agrometeorological disasters that limit the stable and high yield and quality of wheat in China.This study used bibliometric approach to analyze the researches in the field of wheat low temperature stress during 1979—2020 in China based on the China National Knowledge Infrastructure(CNKI)database.These researches are analyzed with respect to the number of published articles,research institutions,authors,document sources,frequency of citations,research hot spots,and funding sources.The results showed that since 1979,the number of publications in the field of wheat low temperature stress in China has shown an overall upward trend.Research institutions represented by Northeast Agricultural University and Northwest Agricultural and Forestry University have been committed to such researches,but there are only limited exchanges and cooperation among research institutions.Highly cited articles have been mostly published in high-quality journals such as Acta Agronomica Sinica and Journal of Triticeae Crops.By identifying key words shared by different researches and conducting the cluster analysis of keywords with high frequency,it becomes clear that current studies of wheat low temperature stress in China mainly focus on the breeding of new wheat varieties with low temperature tolerance;effects of low temperature stress on the growth,yield,and quality of wheat;and molecular biology researches on low temperature stress in wheat.In the future,it is necessary to strengthen the exchanges and cooperation among research institutions,promote collaborative innovation,and enhance the research on the prevention and control technology of wheat cultivation under low temperature stress.They are beneficial to increasing wheat tolerance to low temperature stress,maintaining stable and high yield,improving wheat quality,and reducing loss reduction in wheat production in China.
