海浪是影响舰船行进和结构设计的最核心的环境要素。海浪参数的统计分析是建立舰船环境适应性长期预测模型的基础。对1993-2011年沿海台站、浮标观测资料，高度计观测资料和船舶报观测资料进行双线性插值，给出了海浪波高的分析场。利用波高分析场对WAVEWATCHIII（WW3）模拟结果进行最优插值同化。给出了海浪统计玫瑰图、极端海浪统计参数和海浪累年二维极值海浪谱等与舰船耐波性有关的海浪统计参数，分析了中国近海的波浪特征。

Ocean waves are the core environmental elements affecting the movements and structure design of ships. Statistical analysis of wave parameters is the basis for the establishment of long-term ship environmental adaptability prediction model. The observations from coastal stations, buoys, altimeters and volunteer ships that cover from 1993 to 2011 were interpolated into mil er lon-lat grids by using bilinear method and the analytical fields of ocean waves were given. By using optimal interpolation, the analysis wave fields were assimilated into the WAVEWATCH III (WW3) simulation results. From the assimilated results, the wave rose statistics, the wave height of multiyear return period and the extreme 2-D wave spectrum are related to the ship seakeeping were calculated. Finally, the wave statistics in China offshore were analyzed in detail.
