| 本文通过对实测海平面高度的对比,发现龙口平均海平面从1991年起有明显的升高趋势。作者猜测此乃龙口码头扩建后有系统下沉所致。经对验潮基面和国家水准点进行三等水准测量,证实了作者的猜测。最后,本文应用《海滨观测规范》中的公式,对原来的观测值进行了动态订正,并分析了订正后平均海平面高度场的合理性。 |
| By comparison of observed data it was found that the mean sea level over Longkou port had arisen obviously from 1991 to 1994.Author did guess that was caused by a systematic sinking of the port after its extension.Through the measurement of the tidal datum plane and bench mark the guess was confirmed.As a result these original observations was dynamically corrected by using formulas from the Seashore Observation Standard.At last the rationality of these corrected data was analyzed. |
