摘　　要：波浪能是一种可再生能源,对波浪能资源进行可靠的评估是开发利用的前提。本文利用欧洲中期天气预报中心(ECMWF)ERA-Interim 1981-2015年0.125°×0.125°的较高分辨率的海浪场数据,计算了中国海域的波浪能流密度,采用波浪能流密度的富集度频率和变异系数评价了中国海域的波浪能资源,系统研究了波浪能流密度的季节特征及富集度特征。研究表明:(1)我国周边海域波浪能资源呈现非常明显的季节分布特征,秋冬季较丰富、春夏季较贫乏。(2)波浪能资源的丰富的海区为海南岛以东、广东省以南海域(即南海中北部),同时,台湾岛东部海域波浪能资源也较为丰富。(3)波浪能资源相对稳定的区域为台湾岛以东海域和南海中北部海域,其中冬季稳定性最好,夏季最差。(4)综合考虑到波能资源开发的特点,建议选择广东沿岸海域作为波浪能开发的重点海域。Wave energy is an important marine renewable energy. It is a precondition for the development of wave energy resources to make reliable estimates of the distribution of wave energy resources. Based on 1981--2015 ECMWF ERA-Interim 0. 125×0. 125 reanalysis of higher precision wave field data, we calculated wave power density, frequency of wave energy scale and the stability of the wave energy. The result shows that （1） seasonal distribution characteristic for wave energy is obvious in China sea area, and wave energy resources are richer in winter and autumn and poorer in spring and summer;（2） relatively rich areas of wave energy are located in the area to the east of Hainan island and to the south of Guangzhou, and the area to the east of Taiwan island is rich, too; （3） relatively stable areas of wave energy resource was in the north-central south China sea and in the east of Taiwan island. Winter is the best stable and summer is the worst; （4） considering the utilization of wave energy, it is sugges- ted that emphasis can be put along the coast of Guangdong province.
