Temporal-spatio evolution of maritime accidents

As an important passage connecting China with Southeast Asia, South Asia and the Middle East, the South China Sea has an important geopolitical and economic strategic position. Based on geographic information system (GIS), this paper studies the spatial distribution characteristics of maritime accidents in the South China Sea from 1984 to 2021 in the Lloyd’s List Intelligence(LLI)database, and makes a spatial analysis of maritime accidents in the South China Sea. It is concluded that the hot spots of accidents in the South China Sea are mainly distributed in several important ports and coastal areas of the South China Sea, showing an obvious spatial clustering phenomenon. Meanwhile, combined with the time evolution of the past 40 years, this paper analyzes the spatio-temporal evolution of maritime accidents in the South China Sea, evaluates the risk of different maritime accidents and proposes corresponding prevention strategies, including strengthening supervision, conducting operation and technical training for sailors, using digital system to manage cargo and improving information sharing mechanism to promote cooperation among neighboring countries. In order to improve the safety of navigation in the South China Sea, the results of this study provide a scientific basis for the prevention of maritime accidents in the South China Sea, and are of great significance to the safety management and development of the South China Sea region.
