基于CiteSpace的国内外海洋科技研究现状及热点分析

Current Status and Hotspot Analysis of Marine Science and Technology Based on CiteSpace

为了解国内外海洋科技的研究现状及热点,找出国内外海洋科技研究的差距所在,以美国科学网的核心合集数据库和中国知网数据库收录的1992-2018年相关核心文献作为数据基础,运用CiteSpace可视化软件分析发文趋势、研究热点等。研究结果表明:国内海洋科技领域的发文量滞后于国外;国内对海洋科技研究起步晚,文献影响力较国外偏弱;国内外在海洋科技领域均尚未形成文献高产及高影响力的研究者和研究团队;国内外海洋科技研究的主要力量均分布于高校,并且主要集中于经济较为发达的沿海地区;国内外海洋科技研究热点主要有海洋科技、科技兴海、技术、模型等。最后根据目前中国海洋科技研究存在的不足,分别从加大资金支持、构建学术交流平台、完善教育体系3个方面提出对策建议。

In order to understand the research status and hotspots of marine science and technology at home and abroad,and find the gap between domestic and foreign,this paper takes the core literature included in the database of Web of Science Core Collection and China Knowledge Network from 1992-2018 as the data base,uses CiteSpace visualization software to analyze the trend of publishing papers,research hotspots,etc.The research results show that:in the field of marine science and technology,the number of domestic literature published lags behind that of foreign countries;domestic research starts late,and the literature influence is weaker than the foreign country;at home and abroad both have not yet formed a high-yield literature and high-impact researchers and research team;the main forces are all distributed in universities and are mainly concentrated in the more developed coastal areas;the research hotspots at home and abroad mainly include marine science and technology,technology development,technology,models,etc.Finally,based on the current deficiencies in marine science and technology research of China,this paper puts forward some suggestions from three aspects:increasing financial support,constructing academic exchange platform and perfecting education system.
