国际都市农业研究知识图谱——基于Citespace和VOSviewer的计量分析

Knowledge Mapping of International Urban Agriculture Research: Bibliometric AnalysisBased on Citespace and VOSviewer

为了对国际上都市农业研究现状进行可视化图谱的绘制和分析,探究2007—2016年10年间都市农业研究领域的研究热点与前沿、整体演化路径。本研究以2007—2016年间Web of Science核心数据集中收录的487篇都市农业相关研究文献作为数据基础,充分整合CiteSpace和VOSviewer文献计量可视化软件的优势,采用文献共被引网络、关键词共词网络及突现词分析进行知识图谱的可视化分析。研究发现,都市农业作为一个新兴的研究领域,学者们对其的关注程度总体呈逐年递增趋势。农业/多学科等5个学科具有较强的学科影响力。最有影响力的研究国家是美国,其次是德国、加拿大和英国。研究机构中最有影响力的是德国卡塞尔大学(Kassel University)。(Zezza A 2010)等高被引文献构成都市农业研究领域的知识基础。Urban and Pen-urban agriculture等15个主题聚类构成都市农业研究热点和前沿。都市农业研究主要经历了3个阶段,目前已进入一个兼顾农业生产、农业生态和农业经济全新发展阶段。

The study aims to draw and analyze the visualization mapping of the international research status of urban agriculture, and identify the hotspots and frontiers and overall evolution path of urban agriculture during2007 to 2016. It took 487 literatures related to the urban agriculture, which were included in the core collection of Web of Science during 2007 to 2016, fully integrated the advantage of Citespace and VOSviewer visualization software, and carried on the analysis of the co-citation network, the co-occurrence network and the burst-detection. As a new research field, the concern on urban agriculture increased year by year. 5 disciplines including Agriculture/Multidisciplinary had strong influence. The most influential country was USA, followed by Germany, Canada and the United Kingdom. The most influential institution in the study was Kassel University in Germany.(Zezza A 2010) and other highly cited literatures were the knowledge base of urban agriculture. 15 topic clusters including'Urban and Pen-urban Agriculture'were the hot spots and the frontiers of urban agriculture. The research of urban agriculture mainly experienced 3 stages, and the international research of urban agriculture has entered a new stage taking into account of agriculture production, agriculture ecology and agriculture economy.
