Abstract: In order to understand the rule of the fresh water on the Nanhui east shoal, we have monitored the salinity over a year. After calculating, we know the percentage of the fresh water in the wet season and dry season is from 76.88 to 82.94 percent and from 35.04 to 42.66 percent respectively. If the seasonal and discontinuous fresh water resource is used efficiently, it will supply enough fresh water to the reservoir. The water discharge at Datong hydrometric station plays an important role to the fresh water on the Nanhui east shoal. We shall pay more attention to that there is fresh water when the water discharge at Datong station is less then 10,000 m3/s. The fresh water is affected by other factors such as wind, landform, Coriolis force etc. This paper gives the equations that represent the relationship between the discharge at the Datong station and the fresh water resource.

Key words: fresh water, salinity, water discharge at the Datong station, Nanhui east shoal, fresh water, salinity, water discharge at the Datong station
