| 中文摘要: |
| 在全球气候变化和人类活动的干扰下，海洋生物多样性及其可持续利用受到了严重威胁，对海洋生物多样性的研究也逐渐成为各国学者当前的研究热点。基于Web of Science核心合集的文献数据，利用文献计量学和知识图谱方法，对其发文量的增长趋势、来源期刊和区域分布以及学科类别等进行分析，并基于合作网络、关键词共现的知识图谱及突变检测等方法，探究全球海洋生物多样性的研究进展及其热点。结果显示，研究文献的年度发文量总体上呈动态递增趋势，且文献的科研影响力及国际关注度非常高；发文量较多的作者、机构间均形成了密切而稳定的合作关系，Miloslavich P、Danovaro R和Mouillot D等为该领域的核心作者，以詹姆斯库克大学、塔斯马尼亚大学及不列颠哥伦比亚大学等机构为核心的机构间建立了广泛的合作关系，主要涉及的学科类别为生态学、生物多样性保护、海洋淡水生物学及环境科学等。当前，全球海洋生物多样性的研究热点主要有5个方向：(1)人类活动和气候变化对海洋生物多样性的影响；(2)海洋生物多样性保护及其可持续利用；(3)国家管辖范围外海洋保护区及具有重要生态或生物学意义的海域生物多样性研究；(4)海洋生物多样性和生态系统变化的观测及其评价；(5)海洋遗传多样性和海洋生物多样性的地理变异研究。 |
| 英文摘要: |
| Marine biodiversity and its sustainable use are threatened by climate change and human activities, and research on this topic has drawn increasing interest worldwide. We used bibliometrics and knowledge mapping analysis to review information related to marine biodiversity indexed in the ISI Web of Science Core Collection database. We created descriptive statistics of the number of articles published annually, the journal frequency, and the country distributions. Then, the author, institution cooperation network, and keyword-based knowledge mapping and burst analysis were used to explore hotspots of marine biodiversity research. The descriptive statistics suggest that the number of studies has increased in recent decades, and scientific research influence and international attention are very high. Authors and institutions have formed frequent and stable cooperative networks. Author cooperation has formed core authorships, such as Miloslavich P., Danovaro R., and Mouillot D. Institutional cooperation has enabled extensive collaborations among James Cook University, the University of Tasmania, and the University of British Columbia. Ecology, biodiversity conservation, marine freshwater biology, and environmental sciences are the main disciplines of marine biodiversity. Burst analysis showed that current marine biodiversity research has five study frontiers: (1) the impacts of human activities and climate change on marine biodiversity, (2) the protection and sustainable utilization of marine biodiversity, (3) the establishment and management of marine protected areas beyond national jurisdictions, and the protection of ecologically or biologically significant marine areas, (4) the observation and evaluation of marine biodiversity and ecosystem change, and (5) marine genetic diversity and geographic variations in diversity. |
