摘　　要：唐山丰南港区是唐山港“一港三区”的重要组成部分,对该海域进行余水位特征分析,是实现自然资源科学利用的重要手段。基于丰南站1 a的实测潮位和风数据,通过调和分析、频谱分析和统计分析等方法计算余水位和风的规律,对余水位的成因、规律与风速的关系进行讨论。结果表明:余水位在春、夏季的作用较弱,在秋、冬季的作用较强;春夏季常风向主要是东南偏南—西南偏西;秋冬季的常风向主要是西北—东北。并且余水位与风速呈现较强相关性;11~12月的北向离岸风会导致施测海域发生较大减水。通过余水位与风建立相关关系,减小余水位的预报偏差,以提升短期潮位预报的精度,可对航道通航起到预警作用,从而提升其通航效率。Tangshan Fengnan Port Area is an important part of the"one port and three areas"of Tangshan Port.The analysis of the characteristics of the residual water level in the sea area is an important means to realize the scientific utilization of natural resources.Based on the measured tide level and wind data of Fengnan Station for one year,the regularities of residual water level and wind by means of harmonic analysis,spectrum analysis and statistical analysis were calculated,and discussed the causes,regularities and the relationship between the residual water level and wind speed.It shows that the residual water level has a weaker effect in spring and summer,but a stronger effect in autumn and winter;The normal wind direction in spring and summer is mainly southeast to southwest;The normal wind direction in autumn and winter is mainly from northwest to northeast.And the residual water level is strongly correlated with wind speed;and the northward offshore wind from November to December causes large water reduction in the surveyed sea area.By establishing a correlation between residual water level and wind,the prediction deviation of residual water level can be reduced to improve the accuracy of short-term tide level prediction,which can play a warning role in the navigation of the waterway and improve its navigation efficiency.
