【摘要】：分析20世纪50年代以来福建省7个有代表性验潮站的近700站次台风风暴潮过程,利用建立的风暴潮评价指标,对福建省风暴潮的时空分布特征开展研究。结果表明:福建省风暴潮主要出现在7月至10月,其中以8月最多,9月次之;风暴潮灾害主要发生8月和9月,以9月居多。各级风暴潮中,增水为50~100 cm的风暴潮次数约占70%,沿海各区域中,风暴潮频发区和严重区为闽江口,风暴潮次数明显偏多、偏强;风暴潮灾害频发区为闽江口,风暴潮灾害严重区则依次为闽江口和宁德区域。1954-2008年间,风暴潮发生次数总体呈现上升趋势;风暴潮灾害呈较明显的上升趋势。
[Abstract]:The storm surge process of nearly 700 typhoon stations in 7 representative tidal stations in Fujian Province since 1950s was analyzed and the established storm surge evaluation index was used. The temporal and spatial distribution characteristics of storm surge in Fujian Province were studied. The results showed that storm surge occurred mainly from July to October in Fujian Province. Storm surges occurred mainly in August and September, mainly in September. Among all levels of storm surges, the times of storm surges with water increase of 50 ~ 100 cm accounted for about 70, and in coastal areas. The frequent and serious area of storm surge is the mouth of Minjiang River, the times of storm surge are obviously more and stronger; The frequent area of storm surge disaster is Minjiang Estuary, and the serious area of storm surge disaster is Minjiang Estuary and Ningde region from 1954 to 2008. The storm surge disaster showed an obvious upward trend.

【正文快照】： 风暴潮是来自海上的一种巨大的自然灾害现象(冯士{p,2000),是导致全球生命财产损失最严重的自然灾害之一,也是影响我国最严重的海洋灾害。夏秋之时,东南沿海频繁遭受台风风暴潮袭击(叶琳等,2002),其中尤以浙江、福建和广东省为重,每年均有发生并且成灾率较高,造成严重的人员伤
