我国南海沿海台风风暴潮灾害分析及减灾对策

Analysis of typhoon storm surge disasters along the south China coast and disaster prevention measures

系统总结了我国南海沿海台风风暴潮的生成特点、灾害损失发生规律、灾害特征、灾害成因及强度影响因素等.重点讨论1990—2009年间台风风暴潮的特点,指出近些年来南海沿海台风风暴潮发生频率及其强度均有增加的趋势,特大台风风暴潮发生的频率及损失强度也加大了.最后针对如何有效防御台风风暴潮灾害进行了探讨,以期为珠江三角洲以及海南等地区预防和抵御台风风暴潮灾害提供科学依据.

Such aspects as formation characteristics, the cause of the disasters, the law of disaster loss, disaster intensity and impact factors of the typhoon storm surge are systematically summarized in this paper. Especially the characteristics of the typhoon storm surge-induced disasters from 1989--2009 are analyzed, and then it is pointed out that both the frequency and the intensity of the typhoon storm surge disasters have an increasing trend along the south China coast in recent years, so do those of the super typhoon storm surges. Finally, we discuss how to efficiently defend against the disasters caused by typhoon storm surges so as to give a basis for prevention and defense against the disasters induced by the typhoon storm surges in the Zhujiang River delta and Hainan Province, which often suffer great losses from typhoon storm surges.
