| Abstract: | This paper analyses the some existed question about the actual tidal datum of Pearl River Estuary,then computes and analyses the tidal datum information based on the data of the long-term tide stations of Pear River Estuary hydrologic information system.The scientific and logical tidal datum information consequently is got.One suggestion is brought out to evaluate the scientificity and rationality of the actual tidal datum. |

| Keywords: | tidal datum hydrologic information system least-square abnormal tide guarantee rate |
