| 摘要: |
| 在全球变暖的背景下, 海洋热浪发生频率、强度、持续时间及空间范围均呈现出显著增长趋势, 对海洋生物多样性和生态系统造成极为严重的破坏, 引起了世界各国的广泛关注。CiteSpace是一款具有多元、分时、动态等优势特点的引文分析工具, 可用于分析学科或知识领域的研究发展进程和结构关系。以海洋热浪为主题, 基于Web of Sciences Core Collection数据库, 利用CiteSpace对检索到的514篇相关文献(2012—2021年)进行可视化分析,全面揭示了海洋热浪研究领域的发展趋势、研究热点及前沿。研究发现, 海洋热浪研究的发文量逐年增加, 从2012年至今总体呈现平稳—缓慢上升—迅速增长三个阶段特征。美国和澳大利亚两国在海洋热浪研究中占主导地位。中国虽起步较晚, 但在该领域中影响力不断增强。发文作者集中度较高, 且发文量排名靠前的作者合作关系紧密, 对该研究领域的发展起到了引领作用。海洋热浪研究所属学科主要集中于环境科学与生态学、海洋及淡水生物学、海洋学等。基于关键词共现、突变分析及文献共被引方法, 发现当前研究的前沿热点方向主要包括海洋热浪特征、变率及物理机制, 海洋热浪对海洋生态系统及生物多样性的影响, 气候变化下海洋热浪的响应、适应与减缓。此研究是对该领域文献综述的一个新颖尝试, 为深入研究海洋热浪提供了一定的科学参考和借鉴。 |

| Abstract: |
| Under global warming, the frequency, intensity, duration, and spatial range of marine heatwaves (MHWs) have shown a significant increasing trend. MHWs cause severe damage to marine biodiversity and ecosystems, which has attracted widespread attention worldwide. CiteSpace is a diverse, time-sharping, and dynamic analysis tool for visualizing citations with the development of scientometrics. It can be used to analyze the underlying knowledge in scientific literature. Based on the Web of Sciences Core Collection database, 514 related papers from 2012 to 2021 on MHWs have been retrieved and visually analyzed using CiteSpace. The development trend, research hotspots, and frontiers of the MHW research field have been comprehensively summarized in this study. The results show that the number of published MHW research papers increases annually, experiencing three stages: steady, slow rise, and rapid growth. The United States and Australia dominate the MHW research field. Although China started relatively late, its influence is increasing annually. With high concentration and close cooperation, the prolific authors from this research field play a major role in its development. The disciplines of MHW research mainly include environmental sciences and ecology, marine and freshwater biology, and oceanography. Based on keyword co-occurrence, burstness analysis, and document co-citation methods, the popular topics of current research are found to mainly include the characteristics, variability, and physical mechanism of MHWs, the impact of MHWs on marine ecosystems and biodiversity, and the response, adaptation, and mitigation of MHWs under climate change. This research is a novel attempt to review the literature in this field and provides a promising direction for further study on MHWs. |
