摘要
利用1989—2007年沿海地区的海洋灾害资料,按照海洋气象灾害、海洋水文灾害、海洋地质灾害、海洋生态灾害四种类型,分析了中国沿海地区海洋灾害特征及其危害。结果表明,中国海洋灾害特征主要表现为风暴潮影响范围广,灾情严重;近海污染日益加重,赤潮灾害有所上升;大型海洋溢油事件有上升趋势,形势严峻;海啸灾害发生次数少,但闽、台地区地震海啸灾害潜在危险极大。最后,提出了相应的防治对策:一是加强对海洋灾害的研究和预报,建立和完善海洋灾害预报服务系统;二是加强海岸带防护工程建设,提高防灾标准;三是积极开展防灾减灾宣传工作,促进防灾工程建设;四是加强和完善海岸带综合管理体制,减少人为海洋灾害的发生。
Based on the 1989—2007 data, the marine disasters characteristics and their damage are analyzed according to the 4 kinds of disasters: marine meteorological disaster, marine hydrological disaster, marine geological disaster and marine ecological disaster. the results indicate that the characteristics of marine disaster in China mainly are the broad incidence of storm tide, the severity of damage, the increasing offshore pollution, the red tides, the sea oil spill events and the bigger potential dangers of earthquake and tsunami in Fujian and Taiwan area though they happen infrequently. Suggestions are as follows:(1) strengthening the research on the characteristics of the marine disaster and developing marine disasters forecast system;(2) constructing defence systems in the coastal zone and advancing the standard of disaster prevention;(3) expanding propaganda of disaster prevention and reduction and promoting the development of disaster prevention projects;(4) strengthening the management to reduce man-made marine disasters.
