摘　　要：采用2009年—2018年的ERA5波浪资料,对海上丝绸之路的波浪能资源的有效波高分布、可用波高月际变化特征、波浪能流密度分布、波浪能流密度月际变化特征、能级频率、有效储量、资源稳定性进行分析,为波浪能开发提供依据。结果表明:有效波高的分布特征和波浪能流密度分布特征具有一致性;可用波高呈单峰型月际变化特征,峰值出现在6—9月,数值在40%以上;波浪能流密度月际变化的最高值出现在7月,数值为14.0 kW/m;波浪能流密度大于2 kW/m以上的频率常年都在50%左右,波浪能流密度大于20 kW/m以上的频率在6—8月最高,数值在27%~30%,其余月份较低;波浪能有效储量峰值出现在6—8月,数值在3×10^(3)kW·h/m以上,3—4月有效储量较贫乏;北印度洋的稳定性整体上优于南海,北印度洋冬季和秋季稳定性高于春季和夏季。Based on the ERA5 wave data from 2009 to 2018,the temporal and spatial characteristics(include the distribution of SWH,monthly characteristic of SWH occurrence,distribution characteristic of WPD,monthly characteristic of WPD,monthly characteristic of energy level occurrence,effective storage of wave energy and stability coefficient of WPD)of wave energy of Maritime Silk Road are analyzed in this research to provide a basis for wave energy development.The results show that:the distribution characteristics of SWH are consistent with the distribution characteristics of WPD;EWHO exhibits a single-peak variation characteristic and the peak value appears from June to September with a value above 40%;The peak value appears in July of WPD with a value of 14.0 kW/m;ALO is around 50%all year round,and the peak value of RLO is from June to August,with values from 27%to 30%,and the rest of the other month is lower.The peak value of effective storage occurred in June and August,with values above3×10^(3)kW·h/m,and the effective storage were relatively poor in March and April.The stability of the north Indian Ocean was generally better than that of the South China sea,and the stability of the North Indian Ocean in winter and autumn was higher than Spring and summer.
