摘　　要：在建立近岸区不规则波成长模型的基础上，研究了波浪射线计算、传播能量守恒计算以及成长与衰减能量平衡计算的方法和格式处理，讨论了波数场、风场、水位和流场的确定方法。应用该模型计算了大亚湾的二维波谱场。与该海湾956波浪仪实测资料对比，表明该模型的计算结果与实测资料相符良好。特别指出的是，在该模型的计算结果中周期随波浪的传播而变化。Based on the construction of the model for irregular wave generation incoastal sea area, the computative methods and schemes for wave refraction ray, energypropagation conservation, energy combalance of the generation and dissipation of windwave were researched. The determination method of wave number, wind, water leveland current were discussed. Finally, the model was used for the two-dimensional wavespectrs computation in the Daya Bay, the result was consistent well with the measuredone by 956 Wave Buoy. It was especially pointed out that wave period varied withwave propagation according to the result of our model.
