基于知识图谱的近30年国际海岸带研究进展与热点分析

随着城市化进程加快，海岸带区域环境问题日益突出，与其相关的研究成为学术界的焦点。本文首先基于Web of Science核心数据库，以国家、关键词等信息为研究对象，应用Citespace的知识图谱梳理了海岸带相关研究的脉络，并对其进行了量化与可视化分析。然后通过总结不同时期的研究热点和演化过程，完善海岸带相关的研究，为今后的研究方向与角度提供参考与借鉴。结果表明，随着对海岸带地位特殊性的认识，越来越多的学者投入到海岸带的研究中。分析认为，应用大数据、云计算技术的研究方式及针对大尺度的海平面上升的研究、中等尺度的海岸带的城市生态相关的研究、较小尺度的激光雷达测深等研究是未来主要的研究方向。

Progress and topical analysis of international coastal zone research in the last 30 years based on knowledge mapping

With the accelerated of urbanization, the environmental problems of coastal zone areas are becoming more and more obvious, and the research related to them has become the focus of scholars. Based on the Web of Science database, this paper identifies information such as countries and keywords as the object of study. Application of Citespace's knowledge mapping to sort out the history of coastal zone related research, and to analyse it quantitatively and visually. By concluding the research topics and evolution process in different periods, it helps to improve the research related to the coastal zone and provides reference and reference for future research direction and perspective. As the result shows, more and more researchers are devoting themselves to the study of coastal zones as the specificity of their status is recognised. We have identified the application of big data and cloud computing technologies as well as studies targeting sea level rise at large scales, urban ecology-related studies of coastal zones at medium scales, and LiDAR bathymetry at smaller scales as the main research directions for the future.
