Abstract：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 suggested that emphasis can be put along the coast of Guangdong province.
