摘　　要：联合利用中国沿岸长期验潮站实测资料和全球海潮模型NAO.99b在中国海域的结果,进行潮汐非调和常数的计算。分别对渤海、黄海、东海和南海进行分析,结果表明,中国海域潮汐类型复杂,渤海、黄海、东海以半日潮性质为主,南海以日潮性质为主;渤海、南海平均大潮差多分布在0.42～2.09 m,平均小潮差分布在0.27～1.33 m,东海、黄海平均大潮差多分布在1.12～4.44 m,平均小潮差多分布在0.41～2.41 m;渤海、黄海平均大潮高潮位分布在0.48～1.77 m,东海在0.42～2.41 m,南海在0.21～1.35 m;渤海、东海以及南海北部浅海海域潮高日不等现象显著。The tidal non-harmonic constants are calculated by utilizing the long-term gauge tidal data along China＇s coast in combination with the results of the global tide model NAO.99 b for China＇s sea areas. In terms of the Bohai Sea, Yellow Sea, East China Sea and South China Sea, the results show that China has complex tidal characteristics. The Bohai Sea, Yellow Sea and East China Sea are mainly featured by semi-diurnal tides, with diurnal tides in the South China Sea. The mean spring range in the Bohai Sea and South China Sea is mainly around 0.42-2.09 m, and the mean neap range is 0.27-1.33 m. In comparison, the mean spring range in the East China Sea and Yellow Sea is 1.12-4.44 m, with the mean neap range of 0.42-2.41 m. The mean high water spring in the Bohai Sea and Yellow Sea ranges 0.48-1.77 m, with that of 0.42-2.41 m in the East China Sea and0.21-1.35 m in the South China Sea. The range tidal day phenomenon is obvious in the Bohai Sea, East China Sea and the shallow waters of Northern South China Sea.
