摘　　要：建立了江苏沿海二维潮流数学模型,并采用观测资料对模型进行验证,验证结果表明该模型具有较高的可信度。基于模型一年的计算结果,分析了江苏海域的流速特征;计算潮流能平均功率密度和年有效流时,并给出空间分布特征。结果显示:除连云港海域外,江苏沿海大部分海域潮流能功率密度在200W/m2以上,潮流能年有效流时大于2400 h,在滨海、大丰、东台海域存在潮流能功率密度高值区,辐射沙洲个别水道区域最大值可达1450W/m2;废黄河口、辐射沙洲北部、东部、南部4个特征断面上的潮流能资源理论蕴藏量分别为92MW、157MW、41MW和40MW。A two-dimensional tidal current numerical model in Jiangsu coast area is established and verified using the measured data.The verification shows that the model result is in good agreement with the measured values.Based on the model result for a whole year,the ocean velocity characteristics of Jiangsu coast area are analyzed,and the tidal current energy power density and significant hours are calculated.The results show that,except Lianyungang coast area,the tidal current energy power density in most of Jiangsu coastal areas is more than 200 W/m2,and the annual significant hours is more than 2400 h.High power density occurs in Binhai,Dafeng and Dongtai sea areas,and the maximum value reaches 1450 W/m2 in specific channel of radial sand ridges.The theoretical reserves of tidal current energy resources on four characteristic sections are 92 MW,157 MW,41 MW and 40 MW respectively.
