摘　　要：为了解葫芦岛天角山近岸潮汐潮流泥沙特征,采用准调和分析方法对2020年11月天角山海域大潮期实测数据资料统计分析,得出潮汐、潮流和泥沙特征参数。结果表明:调查海域潮汐性质为正规半日潮,天角山海域潮流时间和空间上存在一定规律,流场总体表现为正规半日潮流,潮流运动方式以NE-SW向往复流为主,调查海域海洋水文特征发生了较大变化,与岸线、地形及人类活动影响有关。In order to understand the tidal, current and sediment characteristics of the nearshore tidal of Tianjiao Mountain in Huludao, a quasiharmonic analysis method was used to statistically analyze the measured data during the spring tide period in November 2020. The results indicate characteristics parameters of the tidal, current, and sediment. The investigation area exhibits regular semidiurnal tides, with two high tides and two low tides occurring each day. The tidal currents in the Tianjiao Mountain area show certain regularity in both time and space. The overall flow pattern is characterized by regular semidiurnal currents, with a predominant NE-SW reciprocating flow. The hydrological characteristics of the investigation area have undergone significant changes, which are influenced by the coastline, topography, and human activities.
