Abstract: |
To understand the focus of and hottest topics in marine scientific research during the past decade, in this study, we analyzed papers published in the major marine core journals during the time periods 2004~2008 and 2009~2013 using the following methods: quantitative analysis, social network analysis, cluster analysis, principal component analysis, and visual display analysis. The results show that four research themes-marine biology, marine aquaculture, marine sediments, and marine environmental pollution-have been the focus of most marine scientific research. New research topics, including marine disasters and maritime rights and interests, have emerged during the more recent period. Marine scientific research in China has followed suit with the development of the national situation, whereby various research topics have gradually subsided, research content has expanded, and research methods and tools have been continuously enriched. |
