In this article low-frequency fluctuations and seasonarchanges of the Mean sea level along the eastern China coast have been analysed, based lipon monthly mean sea level observation at 22 tide-gauge stations. The main results are,, as follows:1.The amplitudes of 18.61-year periodic tide-fluctuation are about 2.5 cm the phases are about 120.2.The seasonal changes of the monthly mean sea level are quite obvious. The annual fluctuation range along the coast north of Changjiang River is larger than that south of it. The highest and lowest of the monthly mean sea level occur in summer and winter respectively in the northern ara ,while tjiey occur in autumn and spring in .the southern area.3.The seasonal sea level change is of annual period and the second oscillation is of semi-annual period. In addition, the 5-year periodic oscillation in the northern area and the 4-month periodic oscilltion in the southern area are also rather significant.4.The static effect of- atmospheric pressure enlarges the annual range of seasonal changes by 13-20 cm in the northern area and reduces the annual .range by 11 em on the west coast of the Taiwan Strait.5.The mean sea level is lower during El Nino years.

本文利用渤海、黄海、东海中国沿岸22个验潮站的月平均水位资料,着重分析了周期在两个月以上的振动和月平均海平面的变化。分析结果表明:(1)18.61年周期的潮汐振动的振幅在2.5cm左右,位相比较一致(约120°左右);(2)月平均海面的季节变化明显,年变幅度北部大,南部小。最高值和最低值北部出现在夏季和冬季,南部出现在秋季和春季;(3)月平均海面以年周期振动为主,其次是半年周期。北部5年周期和南部4个月周期的振动也比较明显;(4)由于静压效应,使北部海平均年变幅度增加13—20cm,而在台湾海峡西岸反而减小11cm;(5)El Nino现象使平均海面出现程度不等的下降趋势。

With the method of analysing tidal oscillation characteristic in the spectral field, what kinds of oscillations existing in tidal process can be known objectively so that the constituent model composed of only fewer constituents will be higher accurate. The method is used to analyze and predict the tide data in the Lian Yung Gang. Results show that selecting constituents blindly and contingently may be avoided with the method and the accuracy in analysis and prediction will be improved.
