摘　　要：针对全球海潮模型在我国近海海域精度较差的问题,该文采用中国沿岸30个长期验潮站的调和常数,对比了3种全球海潮模型DTU10、TPXO7.2、NAO.99b和1个区域海潮模型NAO.99Jb在中国沿岸的准确度。通过海潮模型与验潮站分潮的振幅中误差、迟角中误差以及8个主要分潮的预报误差,对渤海、黄海、东海和南海北部进行了详细的分析。结果表明,NAO.99Jb在中国海域精度最高,NAO.99b次之。在渤海海域,DTU10在Q_1分潮精度最高,NAO.99b在K2分潮精度最高,其余分潮均是NAO.99Jb精度最高;在黄海海域,NAO.99b在Q_1分潮精度最高,其余分潮均是NAO.99Jb精度最高;在东海海域,DTU10在Q_1分潮精度最高,TPXO7.2在P1精度最高,NAO.99Jb在O1、M2分潮精度最高,其余分潮均是NAO.99b精度最高;在南海北部海域,DTU10在N2、S2分潮精度最高,其余分潮均是NAO.99Jb精度最高。The harmonic constituents 30 tidal gauge stations in the China Sea were used to estimate the accuracy of three global ocean tide models DTU10,TPXO7.2,NAO.99 band one regional ocean tide model NAO.99 Jb.The Bohai Sea,Yellow Sea,East China Sea and the northern area of the South China Sea were analyzed by the comparison results between the ocean tide models and tide gauge in terms of the mean square error of amplitude and phase and the root mean square,root sum square of the eight principal constituents.The results showed that the performance of NAO.99 Jb is best,NAO.99 bis secondary.In the Bohai Sea,the precision of Q_1 of DTU10is best;the other constituents are NAO.99 Jb best.In the Yellow Sea,Q_1 is NAO.99bbest;the other constituents are NAO.99 Jb best.In the East China Sea,Q_1 is DTU10best,P1 is TPXO7.2best,O1 and M2 are NAO.99 Jb best,and the others are NAO.99 b best.In the northern area of the South China Sea,N2 and S2are DTU10 best,the others are NAO.99 Jb best.
