Through systematically researching the current situation of coastal hazards (including tropical cycle, storm surge, flood, tsunami, coastal erosion, salt water intrusion, sea-ice, land subsidence, pollution and red-tide) in China, this paper focuses discussion on sea level rise caused by global warming and heightening human activities, as well as the relation among each of them and the evolution of coastal hazards. The results show that, coastal hazards of China are exacerbating due to sea level rise and unreasonable human activities; By the middle of next century, economic losses caused by exacerbating coastal hazards would reach 100 billion RMB yuan in the coastal areas of China. Finally, this paper also puts forward corresponding defensive countermeasures from seven categories, these measures include drafting comprehensive programme for mitigation disas-ter, giving more effective observation and forecasting to coastal hazards, heightening the standard of defence projects, reducing unreasonable human activities and strengthening the awareness of people's preventing disaster etc.
