摘要
采用基于三角形可变分辨率网格系统的三维海洋模型,模拟得到2012—2013年山东周边海域的潮汐潮流。对该海域潮流能进行模拟研究,结果表明:通过检验发现SELFE对山东周边海域的潮汐潮流具有较强的模拟能力。平均流速、最大流速、最大可能流速与能流密度分布一致,较大的区域都发生在渤海海峡和成山头海域,年平均能流密度分别达到600 W/m2和500 W/m2;选取了13个能流密度较大的重点断面,对山东省潮流能资源进行评估,山东省潮流能蕴藏量总量为1 202.9 MW,资源较为丰富。其中,渤海海峡诸水道潮流能蕴藏量为914.2MW,占山东省潮流能总资源储量的76%;成山角断面潮流能蕴藏量为190.3 MW,占山东省潮流能总资源储量的16%。综合以上计算结果及环境因素,文章推荐开发潮流能的海域为渤海海峡诸水道(尤其是北隍城北侧水道)和成山角海域。潮流能的开发利用对于解决能源短缺、改善全球生态环境和维持可持续发展具有重要意义,能够为我国维护海洋权益、迈向深蓝提供科学依据。
Tides and tidal currents simulation during 2012—2013 was constructed to explore the tidal current energy in offshore of Shandong Province,by using the three-dimensional ocean model Semi-implicit Eulerian-Lagrangian finite-element model for cross-scale ocean circulation（SELFE）,which is based on the unstructed,variable resolution triangular mesh system.The validation results show that the model is accurate and robust comparing with the observations.According to the statistics of the simulation results,the larger mean flow velocity,maximum velocity and the maximum probable velocity all occur mainly at the channels in Bohai Strait and Chengshantou Area,which is similar to the tidal current energy flux density distribution.The average tidal current energy flux density at channels in Bohai Strait and Chengshantou area is about 600 W/m2 and500 W/m2 respectively.Thirteen vertical sections with larger tidal current energy flux density were analyzed to assess that the total tidal current energy in offshore of Shandong Province.The results show that the tidal energy resource in Shandong is abundant with the total number of1 202.91 MW,at the forth place in China.The tidal energy at the channels in Bohai Strait is914.2 MW,76% of the total energy;and the tidal energy at Chengshantou area is 190.3 MW,16% of the total energy.Combined with the natural environment,the channels in Bohai Strait（especially Beihuangcheng northern area）and Chengshantou area are the recommended areas to exploit the tidal current energy.
