摘要
研究并总结出符合余水位特点的两站余水位内插方法,并以此在实验海区建立了余水位场,从而利用所得余水位场实现了对由潮汐场所得的潮高模型的订正,再现了实验海区内的瞬时海面,该方法可为海洋大地测量和海道测量提供精确的垂直基准。通过实验,在中国东南沿海海区,监控站间距离在300km以内时,恢复的瞬时海面的中误差可在4 cm以内。
According to the characteristic of residual water level,its interpolation method is researched and achieved.And with this method,the field of residual water level is established to refine the tidal model,the instantaneous water level is recovered and the accurate of vertical datum is given in the process of marine geodetic surveying and hydrographic surveying.Through the experiments in the southeast sea of China,the mean square error of the instantaneous water level prediction can be within 4cm when the distance of the two water level stations is within 300km.
