Studies on Development Trend of International Plant Nutrition Science Using Co-word and Social Network Analysis
摘要
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.关键词
