摘　　要：台风暴潮灾害是影响广州经济社会发展的主要灾害之一,新世纪以来呈愈发严重的趋势。该文以中大水文站为代表,分析2000年以来影响广州的台风的时空特性,结果表明:新世纪以来中心城区珠江高潮位主要由台风引起,年最高潮位呈明显上升趋势。风暴潮最严重时段为7—9月,其中以8月最多,9月次之,按最危险、较危险和其他路径对广州市造成严重影响的台风进行聚类分析,过程平均最大增水2.03~0.84 m,选取典型台风从发展路径、潮位及风暴潮增水规律、降雨等进行具体分析,对广州市未来的风暴潮预报及防灾减灾工作具有一定指导意义。Typhoon storm surge disaster is one of the main disasters affecting the economic and social development of Guangzhou,and it has become increasingly serious since the new century.The paper takes Zhongda Hydrologic Station as a representative to analyze the spatiotemporal characteristics of typhoons that have affected Guangzhou since 2000.The results show that since the new century,the high tide of the Pearl River in the central urban area has been mainly caused by typhoon.The storm surge mainly occurs from July to September,with the largest number in August,followed by September.Cluster analysis is carried out according to the most dangerous,more dangerous and other typhoons that have a serious impact on Guangzhou.The average maximum water increase in the process is 2.03 to 0.84m.The typical typhoons are selected for specific analysis from the development path,tide level and storm surge water increase rule,rainfall,which has certain guiding significance for the future storm surge forecast,disaster prevention and reduction in Guangzhou.
