Causation, impacts and mitigation strategies of typical marine ecological disasters in coasts of the South China Sea

Abstract

In recent years, we have witnessed a significant increase in ecological disasters in the South China Sea, driven by a combination of climate change, marine pollution, and unsustainable resource exploitation. This paper analyzes the frequency of marine ecological disasters in the coasts of South China Sea, utilizing long-term statistical data and historical records to explore the connection between these events and various driving factors such as climate change and human activities. The findings indicate that eutrophication, overfishing, and global warming are the primary external drivers behind the noticeable rise in the frequency of marine ecological disasters in this area. Frequent phenomena include frequent clogging incidents at nuclear power stations due to the overproliferation of the Acetes chinensis and Creseise acicula, and a high proportion of jellyfish stings among all disasters, which have inflicted substantial economic losses on local fisheries, tourism, and energy supply security. In response to these challenges, the paper proposes scientific risk mitigation strategies, emphasizing the implementation of comprehensive management measures in ecologically vulnerable zones and during critical periods. These strategies not only provide a scientific basis for marine ecological management in the South China Sea but also offer references for other worldwide regions facing similar marine ecological challenges.
