| 摘 要： | 本文根据历史水文气象资料，用条件谱分析方法，分析了厦门港水动力因素低频波动特征并探讨其发生机制。结果表明，低频波动清楚地表现为水位和表层盐度的波动。厦门港水位的低频波动主要源自平潭站的水位波动，风的贡献是次要的；条件谱分析了难以描述表层盐度低频波动和九江径流波动的复杂关系。

| Abstract: | Based on historical hydrometeorological data gathered during the period from January1978 to December 1979,low-frequency fluctuation characteristics of hydrodynamic factors ofthe Xiamen Harbour are analysed and their engendered mechanism is discussed using condi-tional spectral anaysis technique.Results show that low-frequency fluctuation clearly ap-pears in water level and surface salinity time series.The low-frequency fluctuation of waterlevel is the Xiamen Harbour is mainly born of the water level fluctuation in Pingtan,the di-rect contribution of longshore wind from both Xiamen and Pingtan are the secondary.Theconditional spectral model is difficult to explain the complex relationship of salinity fluctua-tion with that of the Jiulong River discharge. |
