基于2016年10月至2017年9月在水深7.5m波浪观测站的awac实测数据，分析了三门湾近岸水域的波浪特征。统计分析了波浪参数和波谱变化，讨论了波高分布、波周期分布以及波高和波周期的联合分布。结果表明，实测波高分布与威布尔分布吻合较好。当谱宽较小时，各种波周期理论分布模型对于研究实测波周期分布有各自的参考价值。当谱宽较大时，测得的波周期分布与威布尔分布最吻合。longet - higgins模型（1983）和Sunfu模型可以拟合该海域波高和周期的联合分布，但拟合效果较差。主波方向和强波方向均为E，频率值为40.27%。受台风“塔利姆”影响，观测期内最大浪高（Hmax）为2.71m。
The wave characteristics in the nearshore waters of Sanmen Bay are presented based on the AWAC-measured data from October 2016 to September 2017 at the wave observation station with 7.5m water depth. The wave parameters and the wave spectral variations are statistically analyzed, and the wave height distribution, the wave period distribution, and the joint distribution of wave height and period are discussed. The results indicate that the measured distribution of wave height agrees well with the Weibull distribution. When the spectral width is small, the various theoretical distribution models of wave period have their own reference values for the study of the distribution of measured wave period. The measured distribution of wave period has the best agreement with the Weibull distribution when the spectral width is large. The Longuet-Higgins model (1983) and the Sunfu model can be fitted to the joint distribution of wave height and period in this sea area, but the fitting effect is poor. The dominant wave direction and the strong wave direction are both E, with a frequency value of 40.27%. The maximum wave height (Hmax) of 2.71m was observed during the observation period due to the influence of typhoon Talim.
