Marine Disasters in China and the Strategy for Their Mitigations

China is one of those countries in the world which are frequently hit by marine natural disasters, which cause the economic losses of about 1 billion US dollars a year on an average during 1949–1990. The direct economic losses caused by marine disasters have had a rapidly increasing tendency year after year since the 1980’s. This paper reviews the situation of marine disasters such as storm surge, sea wave, red tide, sea water encroachment and sea ice, and the successes and failures of their reduction. To mitigate losses caused by marine disasters, the strategy for their mitigation, which includes countermeasure, information, scientific and technological research, organization and training is also suggested.
