Based on the three-dimensional hydrodynamic and water exchange numerical model——FVCOM, the water exchange numerical model of Bohai Bay was established, then the observed tide and currents data was used to validate the model result. Using this model, Bohai Bay water exchange was simulated, and the water exchange regularity of Bohai Bay was also studied. The results showed that: Bohai Bay water exchange rate was low, the half period of water exchange was 323 days; the water exchange rate of central Bohai Bay was higher, while the water exchange rate was lower at northwest and southern area; due to the role of the barrier strip, the water exchange rate in the southwest area was the lowest. Therefore, the place and time should be selected before discharging pollutant.
