摘　　要：南日群岛海域岛礁众多,海底地形复杂,波浪传播机制复杂。为了了解该海域的波浪分布特征,采用MIKE 21 SW模块建立了南日岛群岛海域波浪数值模型,利用实测波浪资料对模型进行了验证。根据"莆田试验站公式",利用50年一遇设计风速推算外海深水波要素,然后对南日群岛海域50年一遇的设计波浪进行了模拟,并对该海域的波浪传播特征进行了分析。结果表明,南日群岛内波高较之外海,明显减小,众多的岛礁起到了很好的遮挡保护作用。There are many islands and reefs in the Nanri Islands Sea,the bathymetry is complex and the wave propagation mechanism is complex.In order to understand characteristics of wave distribution in the study area,the MIKE21 SW module was used to establish a wave numerical model for the Nanri islands Sea,and the model results was validated with observed data.According the 50-year return design wind,the deep-water wave elements in the open sea was calculated using the ＂Putian experiment station formula＂.Meanwhile,the 50-year return design wave is simulated and characteristics of wave propagation are analyzed in the Nanri Islands Sea.The results showed that,comparing with the wave height of the open sea,the wave height in the Nanri Islands Sea is significantly smaller,which means that the plenty of islands and reefs play a good protection role.
