%X 为了解唐山曹妃甸近岸潮汐潮流泥沙特征，采用准调和分析方法对2023年5月曹妃甸海域大小潮期实测数据资料统计分析，得出潮汐和潮流特征参数。结果表明：调查海域潮汐性质为不正规半日潮，潮流时间和空间上存在一定规律，流场总体表现为半日潮流特征，北侧潮流运动具备显著的旋转流特征，南侧表现为正规的往复流特征的半日潮，调查海域余流表现为表层最大、底层最小的特征。<br />
In order to understand the characteristics of tidal currents and sediment in the nearshore area of Caofeidian, Tangshan, a statistical analysis of the measured data from the spring and neap tides in May 2023 was conducted using the quasiharmonic analysis method. The analysis yielded parameters describing the tidal and current characteristics. The results indicate that the tidal nature in the surveyed area is irregular semidiurnal tide, with certain regularities in both time and space for the tidal currents. The overall flow pattern exhibits characteristics of semidiurnal tidal currents, with significant rotational flow on the northern side and regular oscillatory flow on the southern side. Additionally, the residual currents in the surveyed area show a maximum at the surface and a minimum at the bottom.
