中国沿岸主要验潮站海图深度基准面的计算与分析

Computations and Analyses of Chart Datum to Coastal Tide Gauges of China

  • 摘要: 对中国沿岸有代表性的15个验潮站的多年潮位观测资料,以年序列进行调和分析并据调和常数计算验潮站的海图深度基准面,分析了由年观测序列求得的调和常数和海图深度基准面的稳定性,研究和更新了理论上可能最低潮面计算中的浅水分潮和长周期分潮订正算法。计算结果表明,中国沿岸不同验潮站的海图深度基准面定义和算法存在差异,新的订正算法计算的可能最低潮面和最低天文潮面具有意义一致性,研究成果能够用来精化和重新构建中国沿岸海图深度基准面。

     

    Abstract: 15 typical tidal gauges along the coast of China are selected for the research of their chart datum.The harmonic constants are analyzed through the least squares with multi-year water level observations.The stability for the datum values computed through different algorithms are studied according to statistics.The algorithms of the correction of shallow water tides and long period tides to the lowest normal low water(LNLW) are renewed.
