【摘要】：为了解近10年来中国海洋科学研究的重点和热点主题,作者运用科学计量分析方法以及社会网络分析方法中的聚类分析、主成分分析和可视化展示等研究手段,对主要海洋核心刊物在2004~2008和2009~2013年两个阶段共10年间发表论文的高频关键词进行计量分析。分析和对比结果发现,海洋生物、海洋水产养殖、海洋沉积环境和海洋环境污染这4个研究主题始终是10年来中国海洋科学研究的重点,新阶段也出现了海洋灾害、海洋权益等新研究主题。中国的海洋科学研究紧跟形势发展,研究主题逐渐明确,研究内容进一步扩展,研究方法和手段不断丰富。
[Abstract]:In order to understand the key and hot topics of China's marine science research in the past 10 years, the authors have made use of Scientific Metrology and social network analysis methods, cluster analysis, principal component analysis and visual display, to publish a high number of papers on the main marine core publications in the two stages of 2004~2008 and 2009 ~2013 years. The analysis and comparison results show that the 4 research topics of marine biology, marine aquaculture, marine sedimentary environment and marine environment pollution have always been the focus of China's marine science research in the past 10 years, and new research themes, such as marine disasters and marine rights, are also presented in the new stage. The Research of Marine Science in China is closely followed. With the development of the situation, the theme of research has been gradually clearer, the content of research has been further expanded, and research methods and means have been enriched.
