基于VOSviewer和CiteSpace的耕地质量研究态势分析

Cultivated land quality research situation analysis based on VOSviewer and CiteSpace

  • 摘要: 为了解当前耕地质量领域的研究热点和前沿方向,进一步深化相关研究,采用文献计量学方法分析该领域的研究热点及趋势。运用VOSviewer和CiteSpace软件对来源于中国知网的1258篇有效文献及Web of Science核心合集数据库中的3730篇有效文献进行分析。其中,利用VOSviewer 软件绘制作者合作及关键词共现知识图谱,CiteSpace软件绘制关键词聚类、关键词突现、关键词时间线等知识图谱。从发文数量、作者、关键词等方面对1992—2022年耕地质量领域文献进行可视化分析。结果表明,中文文献发文量在2007—2015年快速上升,英文文献发文量在2018—2022年直线上升,英文文献发文量整体高于中文文献发文量;作者共现显示,中文文献中作者形成了以孔祥斌、吴克宁、马友华为代表的研究团队,英文文献有以HU Chengxiao、LU Jianwei、LI Xiaokun为代表的研究团队;关键词相关图谱显示,国内的研究热点包括耕地质量评价、土地整治、土壤肥力和耕地质量相关对策研究,国外的研究热点包括土壤基础地力、环境质量、环境污染和空间布局。未来耕地质量领域研究将继续利用遥感手段研究耕地质量时空变化及等级评价,在保护环境的前提下提升耕地产能、确保国家粮食安全、降低人类健康风险将是未来的研究重点。

     

    Abstract: In order to understand current research hotspots and frontier directions in field of cultivated land quality and further deepen relevant research, bibliometrics method was used to analyze research hotspots and trends in this field.VOSviewer and CiteSpace software was used to analyze 1258 valid documents from CNKI and 3730 valid documents in the core collection database of Web of Science.Among them, VOSviewer software was used to draw knowledge map of author cooperation and keyword co-occurrence, and CiteSpace software was used to draw knowledge map of keyword clustering, keyword emergence, keyword timeline, etc.A visual analysis of documents in the field of cultivated land quality from 1992 to 2022 was made in terms of number of documents issued, authors, keywords, etc.Results showed that number of Chinese documents issued increased rapidly from 2007 to 2015, and number of English documents issued increased sharply from 2018 to 2022.The number of English documents issued was higher than that of Chinese documents as a whole.The authors now showed that in Chinese literature database, the authors have formed a research team represented by KONG Xiangbin, WU Kening and MA Youhua.In English, there were research teams represented by HU Chengxiao, LU Jianwei, LI Xiaokun.Keywords relevant atlas showed that domestic research hotspots included cultivated land quality evaluation, land remediation, soil fertility, and cultivated land quality related countermeasures, while foreign research hotspots included soil basic fertility, environmental quality, environmental pollution, and spatial layout.In the field of cultivated land quality in the future, remote sensing would continue to be used to study temporal and spatial changes of cultivated land quality and grade evaluation.On premise of protecting tenvironment, improving productivity of cultivated land, ensuring national food security and reducing human health risks would be focus of future research.
