１９９２年６～７月，中国科学院海洋研究所在镆岛港建立临时验潮站。计 算得到该港调和常数及潮位特征值。分析表明，镆　岛港属于非正规半日潮港。根 据镆岛港和同期及３年石岛港测得资料（二港符合潮汐相似性条件）进行相关分 析和统计计算，获得镆　岛港的设计水位和校核水位等。 From June to July 1992, Institute of Oceanology, Chinese Academy of Sciences established a temporary tide station at Chengdao Port. The Hong Kong Harmonic Constants and tidal characteristic values ​​are calculated. The analysis shows that Chengdao Port belongs to the informal semi-day tide port. Based on the data obtained from Chengdao Port and the data from Shijiazhuang Port during the same period and for three years (the two ports meet the tide similarity conditions), the design and verification levels of Chengdao Port were obtained.
