| 摘要: |
| 采用二维潮流数值模型和水质模型探讨了钦州湾污染物的扩散规律,利用钦州湾海域现场观测数据,计算了钦州湾的海水交换率,平均半更换期及环境容量。计算结果表明,在较大潮汐时,钦州湾的海水交换率为0.124,平均半更换期为7.2个潮周期,保持一级海水的COD排放量为每个潮周期234.5t,保持二级海水的COD排放量为366.9t。 |

| Abstract: |
| The rules of pollutant transportion of the Qinzhou Bay were discussed by making use of two-dimensional tidal current model and water quality model. Based oil the marine investigation data, the turn-over rate, half exchange period and environmental capacity were computed. The results show that under bigger tide the turn-over rate of the Qinzhou bay is 0.124, half exchange period is 7.2 tidal periods, the permitted discharge of COD for first-class sea water is 234.5 t per tidal period and that for second-class is 366.9 t per period. |
