摘　　要： 深度基准面是确定海洋水深的基准,通过长期的潮汐观测可以比较准确地确定深度基准面,但对于短期的潮汐观测则无法准确地确定其基准。本文在分析不同国家深度基准确定的方法基础上,针对短期潮汐观测提出了利用内插法、水准测量法确定深度基准面的方法,经过实际应用,该方法精度高,可以广泛应用到海洋测绘、航道、疏浚、港口建设等领域。 The depth datum is the base which determined the depth of the ocean, it can be accurately deter- mined by used of long-term tidal observation, but for short-term tidal observation the reference can not be accu- rately determined. Based on the analysis on the methods of determining the datum in different countries, the paper used interpolation method and level measurement method for the short-term tidal observation to determine the da- tum. Through practical application, it was proved that this method could be widely applied in marine surveying and mapping, channel, dredging, port construction, etc. with high accuracy.
