摘　　要：潮流对海上交通安全、生态保护等具有重要影响,掌握潮流特征对潮流预报、航行安全和科学研究具有重要意义。周日潮流观测数据因数据时长较短,潮流特征分析往往不够精准可靠。本文采用引入差比关系的准调和分析法就1次周日潮流观测数据展开分析,并就潮流表示方法进行了简要介绍。以山东半岛南部海域验流数据为例进行实验,结果表明:该方法可以为观测海区提供较为可靠的潮流特征值,为航行安全和海洋发展提供基础数据保障,同时本文研究方法也将为周日潮流观测数据分析提供参考。Tidal current has an important impact on marine traffic safety and ecological protection,and the characteristics of tidal current is of great significance for tidal current prediction,navigation safety and scientific research.Due to the short duration of daily tidal current observation data,the analysis of tidal current characteristics is often not accurate and reliable.In this paper,the quasi-harmonic analysis method introducing of difference ratio relation is used to analyze the observed daily tidal current data of hydrographic survey,and the method of tidal current portrayal is briefly introduced.Taking the current tidal data of the southern sea area of Shandong Peninsula as an example,the results indicate that this method can provide more reliable tidal current characteristic values for the observed sea area,and provide basic data guarantee for navigation safety and marine development.Meanwhile,the research method in this paper will also provide reference for the analysis of the daily tidal current observation data of hydrographic survey.
