摘要 为江苏辐射沙洲湿地开发和沿岸港口建设的需要,研究并建立了辐射沙洲海域及沿岸港口最大可能潮差的计算公式.利用改进的G·Godin潮汐调和分析程序对江苏省辐射沙洲海域的21个验潮站潮位资料进行分析.利用Delft3D数值模型对辐射沙洲海域潮流动力进行计算,得到模拟海域8个主要分潮的潮汐调和常数.运用统计分析方法,给出适用于江苏辐射沙洲海域最大可能湖差的计算公式.经验证,该公式筒捷、实用,其相对误差绝对值均小于0.5%. For Jiangsu radial sand ridges wetland development and its coast harbors construction, the formulas for calculating the maximum possible tidal difference of the Jiangsu Radial Sand Ridges and its coast harbors were established. The tidal level data of 21 tidal level surveying sites in Jiangsu radial sand ridges sea area were analysed by using the improved G· Godin' s tidal level harmonic analysis and prediction procedures. The tidal dynamical values were computed by using the Delft3D model, and tidal harmonic constants of the 8 principle tidal components were obtained. The formula for calculating the maximum possible tid- al range applicable for Jiangsu radial sand ridges sea area was given. Tests show that the proposed formula is concise and practical, and all the absolute value of relative errors are less than 0.5%.
