Abstract:

Research profiling based on quantitative analysis is an important method to describe the existing status and identify the development direction of the disciplines, which has provided more and more decision-making references for disciplines strategic layout. Co-word analysis and social network analysis were used to profile the discipline of plant nutrition science. Data from 3 top journals in this discipline catalogued by SCI were collected. Based on co-word analysis, this discipline was divided into some subjects, and their annual change trend were analyzed. Furthermore, the institution collaboration network and the 2-mode network about subjects & institutions in the discipline were described, characteristics of the 2 networks were studied. The results showed that plant nutrition science could be divided into 8 subjects, and 2 of them showed stronger upward tendency. INRA, Univ. Calif., Univ. Wageningen and CSIC were in the center of the TOP10 institutions collaboration network. The Chinese Acad. Sci.s research focused on 7 subjects of the 8. “Nitrogen, phosphorus, fertilization” was the most important subject for the TOP10 institutions. China should focus on the rising subjects and the hot topics, strengthen the collaboration with the institutions located at the center of cooperation network. Results from this study can help Chinese researchers and managers make appropriate decisions in disciplinary arrangement and selection of cooperative partners.

Key words: plant nutrition science, trend analysis, co-words analysis, social network analysis

摘要：

以定量文献分析为基础的态势分析是厘清学科现状、识别发展方向的重要方法,为越来越多学科的战略布局提供着决策参考。运用共词分析与社会网络分析相结合的方法,研究了国际植物营养学学科发展态势。以SCI收录的三种国际植物营养学重要期刊2001-2014年刊载的论文为数据源,采用共词聚类对学科进行了主题领域划分,并研究了各领域的发展变化趋势；通过一模网络及二模网络对该学科重要研究机构合作网络的特征及研究布局进行了剖析。研究结果表明：基于共词聚类,2001-2014年国际植物营养学方面的研究大致可分为8个主题领域,其中,“拟南芥、基因表达、转录因子”和“动态、碳、生态系统”两个主题的增长势头较强；法国农业科学院、美国加州大学、荷兰瓦赫宁根大学和西班牙高等科学研究理事会等4家机构处于国际植物营养学合作网络的中心；中国科学院研究覆盖面最广,在7个研究主题上均有大量布局；“氮、磷、施肥”主题是主要机构的研究热点。因此,我国应重视在上升主题和热点主题上的布局,加强与合作网络中心机构的合作。本研究结果可为我国植物营养学科研人员和管理者布局研究重心、寻找合作对象提供参考,帮助其提高科研效率。
