摘　　要：以高精度的CCMP海面风场和ETOPO5地形数据为输入,以第三代海浪模式WAVEWATCH-Ⅲ为工具模拟研究台湾岛周边海域10年内的波浪能资源,并计算分析台湾岛周边海域的波高参数和波浪能流密度,以探测其波浪能资源含量。研究结果表明:台湾岛周边90%海域2008-2017年的平均波浪能流密度超过了3 kW/m,最高可达18 kW/m,且冬季的平均波浪能流密度最大,夏季最小;台湾岛周边海域5个位置的模拟有效波高和实测波高的偏差绝对值为0.067~0.457 m,相关系数为0.684~0.826,因此,可用模拟的有效波高进行波高的预测分析;大波高持续的周期较长,小波高持续的周期较短;台湾岛周边海域的波浪能资源稳定性高,为波浪能资源优势区域。Taking the high-precision CCMP sea surface wind field and ETOPO5 topographic data as input, the study used the third generation wave mode WAVEWATCH-Ⅲ to assess the wave energy resources in the waters around Taiwan Island from 2008 to 2017. According to the research: the average wave power density of the 90% waters around Taiwan more than 3 kW/m, the largest value is up to 18 kW/m. According to the seasonal distribution of average wave power density, the overall level of wave power density in winter is the largest, but the overall value of summer is smallest. By compared the simulated significant wave height with the measured wave height in five positions, the absolute deviation is between 0.067 m and 0.457 m, the correlation coefficient is between 0.684 and 0.826, the simulated significant wave height therefore can be used for calculation of wave parameters. In addition, from the variation trend of significant wave height and average wave period, there is good consistency between significant wave height and wave period. To sum up, the wave energy resources in the waters around Taiwan Island are rich and stable, it is suitable for the development of wave energy resources.
