摘要
利用M.Foreman改进的G.Godin潮汐调和分析程序对江苏省辐射沙洲海域21个验潮站潮位资料进行调和分析,得到了11个分潮的调和常数及相应平均海平面.利用Delft3D数值模型计算研究该海域8个分潮的调和常数.对21个站位理论最低低潮面、可能最低低潮面、略最低低潮面及英国海图深度基准面的空间分布特征及关系进行了计算分析,拟合得出了辐射沙洲海域理论最低低潮面的经验关系式,利用该关系式计算分析了江苏省辐射沙洲海域理论最低低潮面值及其空间分布特征.
The tidal level data from 21 tidal stations in radial sand ridge sea area of Jiangsu Province are analyzed by use of G-Godin＇ s tidal harmonic analysis and prediction programs revised by M Foreman, and the harmonic constants of 11 constituents and corresponding mean sea level are obtained. The Delft3D numerical model is also used for calculation of the harmonic constants of 8 constituents in this area. Moreover, the theoretical depth datum （TDD）, the possible lowest tidal level, and the Indian spring low tidal levelof 21 tidal stations, as well as their depth datum on British marine charts are analyzed, and an empirical formula for the TDD of this area is fitted by SPSS software. With the formula, the TDD and its spatial distribution of this area were calculated.
