| 系统地探明海岸带遥感的研究现状和发展趋势，对于应对海岸带地区面临的生态系统功能下降、自然岸线损失、水质恶化等问题具有至关重要的意义。为了充分明晰海岸带遥感研究现状及发展趋势，本文以“海岸带遥感”为主题，基于Web of Science数据库，筛选出1990—2019年发表的相关文献共6 083篇；从论文发表基本情况、科研合作和研究内容聚焦及主题演变方面进行了较为系统的文献计量评价和知识图谱分析。在文献发表基本情况方面，1990—2019年间海岸带遥感发文量呈现较为稳定的上升趋势；区域性特征明显，主要集中于各大洲沿海地区，发达国家在该领域的研究中占据主流地位;Remote Sensing of Environment是该领域刊文量最高的期刊，且具有最高的影响因子；美国、中国科学院和Hu C M分别为发文量最高的国家、机构和作者；根据H指数的分析结果，相关科研成果的学术影响力仍有待进一步提升。在科研合作方面，美、英等发达国家之间形成了较为紧密的合作网络；虽然中国科学院是发文量最大的科研机构，但是中介中心性仅为0.09，低于美国国家航空航天局（0.16）和美国国家海洋与大气管理局（0.12），因此应进一步加强与其他研究机构的合作；Hu C M与其他学者之间的学术合作最为紧密。在研究内容聚焦及主题演变方面，海岸带遥感领域的研究主题呈现多元化的趋势；研究内容主要聚焦于水色、海岸线、土地利用/覆盖、生态系统监测、灾害和城市化等方面。 |

| Abstract: |
| It is of great significance to fully explore the research status and development of remote sensing in coastal zones to deal with the ecosystem function decline, natural shoreline loss, water quality deterioration and other problems of coastal zones. To fully identify the current situation and development trend of coastal zone remote sensing research, the present work studies 6 083 literatures with the topic of “coastal zone remote sensing” from 1990 to 2019 based on the Web of Science databases. Systematic bibliometric evaluation and knowledge map analysis were conducted in views of basic information of paper publication, scientific research cooperation, the focus of research content and the theme evolution. In regard to basic information of paper publication, the amount of remote sensing publications in coastal zones increased steadily from 1990 to 2019. This is obvious for their regional characteristics concentrated mainly in the coastal areas of all continents, where developed countries led a position. The journal of “Remote Sensing of Environment” was characterized by the highest number publications and the highest impact factors. America, Chinese Academy of Sciences, and Hu C M were the country, institution and author with the highest number publications, respectively. According to the analysis of H index, the academic influence of relevant scientific research achievements still needs to be improved in further. In regard to scientific research cooperation, there existed a relatively close collaboration network among USA, England and other developed countries. Although the Chinese Academy of Sciences was the most productive institution, the value of intermediary centrality was only 0.09, which was lower than those of the National Aeronautics and Space Administration (0.16) and the National Oceanic and Atmospheric Administration (0.12). Therefore, the collaboration with research institutions abroad should be strengthened in future. Hu C M had the most closed academic cooperation with other scholars. In regard to research topics and frontiers, the trends are much diversified. The research contents of coastal zone remote sensing mainly focused on water color, coastline, land use/cover, ecosystem monitoring, disaster and urbanization. |
