摘要： 采用三维水动力和水交换数值模型FVCOM,建立了渤海湾附近海域的水交换数值模型,经实测潮汐和潮流数据验证,模型结果良好,并通过模型对渤海湾的水交换过程进行了研究。结果表明,渤海湾海域总体水体交换率较低,水体半交换周期达323 d;渤海湾中部海域的水交换率相对较高,西北部海域和南部海域的水交换率较低,尤其是西南部海域,由于阻隔带的作用,水体交换能力最弱。因此,在进行污染物排放时,应注意选择污染物的排放位置和排放时间。

Abstract: 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.

Key words: Bohai Bay, numerical simulation, water exchange
