基于文献计量学的棉花秸秆研究现状与热点分析

Research Status and Hotspot Analysis of Cotton Straw Based on Bibliometrics

为了把握国内外棉花桔秆的研究现状与发展趋势,为棉花桔秆的深入研究与信息交流提供文献依据,以中国知识资源总库(CNKI)、Web of science数据库为文献源,采用文献计量学方法,对棉花秸秆文献按年度分布、研究领域、关键词、载文期刊等特征进行检索与计量分析;查得中文载文378篇(1986年7月~2021年12月)、外文载文481篇(1933年1月~2021年12月)。采用文献计量学方法,利用Excel、VOSviewer等软件进行统计处理,构建中外棉花秸秆研究领域发文量时序分布、发文期刊、研究热点的各类知识图谱。分析表明,目前国内棉花秸秆研究主要集中于棉花秸秆的产量、力学性能、秸秆还田等方面。国外棉花秸秆研究聚焦于应用效能、热解、结构特征等方面。最后,提出棉花秸秆研究未来展望,多学科交叉融合视角下的棉花秸秆研究亟待推进,棉花秸秆生物质能源应用有待深入研究,棉花秸秆研究的国际合作有待进一步拓展。

In order to grasp the research status and development trend of cotton straw at home and abroad, and provide literature basis for in-depth research and information exchange of cotton straw, China National Knowledge Infrastructure(CNKI) and Web of Science database as literature sources, literatures on cotton straw research were retrieved and analyzed bibliometric ally based on annual distribution, research fields, keywords and periodicals. 378 articles in Chinese(July 1986 ~ December 2021) and 481 articles in English(January 1933~December 2021) were found. Using bibliometric methods and using Excel, VOSviewer and other software for statistical processing, various knowledge maps of the time-series distribution of published papers, publishing institutions, and research hotspots in the field of cotton straw research at home and abroad are constructed. At present, domestic cotton straw research mainly focuses on the yield, mechanical properties, and straw returning of cotton straw. Foreign cotton straw research focuses on application efficiency, pyrolysis, and structural characteristics and so on. Finally, the future prospect of cotton straw research is put forward. The research on cotton straw from the perspective of multidisciplinary cross-integration needs to be promoted urgently, and the application of cotton straw biomass energy needs to be further studied, and the international cooperative research of cotton straw needs to be further expanded.
