摘要： 基于1980—2017年实测潮位等资料，运用统计分析和数值模拟方法研究了海口市风暴潮分布特征与影响因子。结果表明：海口市受风暴潮影响较频繁，年均2.79次，通常发生在7—10月，且风暴潮引发的潮灾概率较大；风暴增水平面分布表现为：东寨港风暴增水强度位居第一，其次是秀英港，第三是海甸岛，南港增水相对较弱。影响因子体现为：地形的权重通常比热带气旋移动路径更大；热带气旋移动速度对海口市风暴增水有明显影响，移动速度为14~19 km/h时，风暴增水往往达到最大。

Abstract: Based on the measured water level data of Xiuying Station from 1980 to 2017, the distributional characteristics and influencing factors of storm surge in Haikou were studied by using the methods of statistical analysis and numerical model. It is found that Haikou is frequently affected by typhoon storm surge, with an annual average of 2.79 times, which usually occurs from July to October, and the probability of tidal disaster caused by storm surge is high. The horizontal distribution of storm surge shows that the storm surge intensity of Dongzhai Port ranks first, followed by Xiuying Port, Haidian Island and South Port. Influencing factors show that the weight of topography is usually greater than the moving path of tropical cyclone storm surge in Haikou; when the moving speed of tropical cyclone is 14-19 km/h, the storm surge in Haikou is usually the largest.
