Abstract: 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.
