摘　　要：通过随机粗糙海面的P-M谱密度函数,建立基于Monte-Carlo方法的三维随机粗糙海面模拟模型,并得到随机粗糙海面的均方根高度和相关长度的解析解。利用数值模拟方法产生随机粗糙表面的高度起伏,数值模拟了不同参数下的三维随机粗糙海面。理论分析和仿真结果表明,海面高度起伏随风速增大而增加,与实际情况一致。A model of two-dimensional random rough ocean surface is established through P-M spectral function of two-dimensional random rough surfaces by using Monte-Carlo method. Its analytic solutions of the roughness parameters （root mean square of the surface height and correlation length） are worked out. The fluctuation of the random rough ocean surface is gotten with the numerical modeling, what is analyzed is the wind speed figure characteristic. The analytic solutions and simulation results indicate that the fluctuation of the random rough ocean surface raising with the wind speed, in line with practical situation.
