基于Bibexcel和Pajek的海洋生态环境保护领域科学计量与知识图谱分析

利用文献处理工具Bibexcel和网络分析工具Pajek对SCIE和SSCI文献数据库1990—2020年全球海洋生态环境保护文献数据进行统计与可视化分析，以期揭示该领域的科研产出情况、领域知识基础、研究热点分布及前瞻发展态势。研究结果表明：海洋生态环境保护领域文献产出近30年来持续增长；美国、澳大利亚、加拿大、法国等国家在该领域内有着较强的科研竞争力和学术影响力，其中美国处于研究合作核心地位，美国加利福尼亚大学、法国国家科研中心等机构为主要发文机构；海洋生态环境保护研究的热点方向主要为海洋生态环境修复与管控、气候变化、生态系统服务、海洋保护区等；该领域研究学科交融趋势明显，研究者应充分借鉴、吸收其他学科理念和方法，加强海洋生态环境与气候变化、人为活动及生态物种等因素的制衡与协同。

Scientific measurement and knowledge map analysis in the field of marine ecological environmental protection based on Bibexcel and Pajek

Using the document processing tool (Bibexcel) and network analysis tool (Pajek) to perform statistical and visual analysis on the SCIE and SSCI document database from 1990 to 2020 for global marine ecological en-vironmental protection literature data, revealing the scientific research output, domain knowledge base, and research hotspot distribution in this field and forward-looking development trends. The results of the study show that: the literature output in the field of marine ecological environmental protection has continued to grow in the past 30 years; the United States, Australia, Canada, France and other countries have strong scientific research competitiveness and academic influence in this field, of which the United States is at the core of research cooperation; The University of California, the French National Research Center and other institutions are the main document issuing organizations; the hotspots of marine ecological environmental protection research are mainly marine ecological environmental restoration and management, climate change, ecosystem services, marine protected area, etc.; The trend of blending research disciplines in this field is obvious, and researchers should fully learn from and absorb the ideas and methods of other disciplines to strengthen the checks and balances between the marine ecological environment and climate change, human activities, and ecological species.
