Abstract: With the proposal of the ‘3060’ goal, wave energy, as a sustainable and clean energy source, has received more and more attention. For studying the wave enery resources in Jiangsu coastal area, a wave model is established and the wave energy resources in the study area from 2021 to 2023 are taken as the analysis object. By using this model, the flux density distribution, effective wave hours and seasonal variation indexes of the wave energy in Jiangsu coastal area are studied preliminarily. The results show that the annual average flux density of wave energy ranges from 0 to 11 kW/m and the effective wave hours vary between 0 and 6 000 hours. In the deep sea area beyond the Yangtze River Estuary the wave energy flux density and effective wave hours are relatively greater, while within the Haizhou Bay they are relatively smaller. The closer to the outer sea it is, the greater the wave energy flux density and effective wave hours will be, and the lower the latitude is, the more obvious the increase of the wave energy flux density and effective wave hours towards the outer sea will be. The seasonal variation indexes of the wave energy in Jiangsu coastal area range mainly from 0.3 to 1.0, with the relatively higher indexes occuring in the offshore area from the south side of the Haizhou Bay to the north side of the Yangkou Port and in the deep sea area beyond the Yangtze River Estuary. This study can provide references for the development and utilization of wave energy resources and the site selection of wave energy power stations in Jiangsu and other coastal areas.
