摘要： 目的 利用CiteSpace绘制期刊刊文的知识图谱,优化我国科技期刊定位和选题,提高我国期刊的学术影响力。方法 以我国9种生态学核心期刊为研究对象,梳理这9种期刊2015—2019年刊载的高被引论文,利用CiteSpace可视化软件对9种期刊2015—2019年刊文的关键词进行聚类分析,提炼国内生态学核心期刊的研究热点,并与国际顶尖生态学期刊刊文的研究热点进行对比。结果 我国生态学核心期刊刊文反映了生态学科的热点选题,但对于热点选题的报道不足,一些稀缺的热点选题需要加强选题组稿。结论 运用CiteSpace软件进行期刊刊文的知识图谱分析,有助于梳理期刊选题脉络,进一步优化期刊定位和选题方向。
[Purposes] This paper aims at optimizing the journal positioning and topic selection through mapping knowledge domain obtained by CiteSpace, so as to improve the academic influence of Chinese scientific journals. [Methods] We selected nine core journals as research objects. The highly cited papers published in these journals from 2015 to 2019 were sorted out. Based on CiteSpace, we conducted the co-word analysis in the past five years for these journals, and revealed and compared the research focuses of 9 Chinese core journals and 5 international top ecology journals. [Findings] The articles published in China's ecology core journals reflect the research hotspots of ecology. However, the articles on research hotspots are insufficient, and some scarce research hotspots should be involved in the topic selection and planning in the future. [Conclusions] The application of CiteSpace in scientific journals helps to sort out the research hotspots and provides a new way to optimize journal positioning and topic selection.
