摘要
首先回顾了2008年5月发生在缅甸的"纳尔吉斯"特大风暴潮灾,从海洋与气象系统、地理环境和人口环境这三方面分析其造成巨大危害的原因;以一些例子说明,全球气候变暖,导致极端自然灾害出现的强度和频率呈不断上升趋势.随后分析上海海洋灾害主要来自三个方面:因大气强烈扰动而产生的灾害,如台风和巨浪等:因海水的扰动或状态骤变而引发的灾害,如海啸和风暴潮等;因人类活动而出现的灾害,如赤潮和海洋污染等.以大量的数据说明,强风暴灾害是上海的主要灾害;海浪灾害对上海的航运事业构成严重威胁;海平面上升是上海主要的重大灾害隐患.介绍了上海市海洋灾害应急预警服务体系的现状和问题.并就新气候形势下上海海洋灾害的应对措施,提出了机制建设和能力建设等具体的建议.
