Study on Map Knowledge Domains of Transgenic Maize Based on Citespace

Abstract

The purpose of this paper is to analyze the hotspot and trend of the studies on global transgenic maize from 2005 to 2015. The paper is mainly based on bibliometric method, taking studies on transgenic maize from 2005 to 2015 which are included in the core journals in the database of Web science as samples, and using Citespace for visual analysis of mapping knowledge domain of studies on transgenic maize. As a result, 2851 pieces of documents have been retrieved and the literatures are in a stable situation and show a tendency of increase. According to Citespace, it has drawn a mapping knowledge domain on scholars, institutions, citation and key words. Therefore, by cluster analysis, it is found that in the study of transgenic maize, Chinese scholars and institutions hold an advantage in quantity while the hotspot of global research is mainly about flora, genes, protein and resistant, etc.
