基于CiteSpace的国内外海洋科技研究现状及热点分析

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。

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

In order to understand the research status and hotspots of marine science and technology at home and abroad, we find the gap between marine science and technology research at home and abroad. Based on the core literature of domestic and foreign databases in 1992-2018, the CiteSpace visualization software was used to map knowledge maps such as author cooperation maps, institutional cooperation maps, and research hotspot maps. The results show that the domestic publications lag behind foreign countries; the domestic marine science and technology research started late, the literature research influence is weaker than foreign countries; there are no authors and research teams with high yield and high influence at home and abroad; The main forces are distributed in colleges and universities, and mainly concentrated in the coastal areas with more developed economy; the research hotspots at home and abroad mainly include marine science and technology, marine fisheries, marine environmental protection, sustainable development, etc. Finally, according to the existing deficiencies, they are separately increased. Suggestions on financial support, building an academic exchange platform, and improving the education system.
