| 摘 要： | 在估算大鹏湾污染源强及统计海水污染物浓度的基础上,采用三维水动力模型及污染物扩散模型,模拟了大鹏湾的海水交换及污染物扩散过程,分析了大鹏湾海水交换与生化降解对自净能力的贡献.结果表明,大鹏湾潮差小,约为1m,潮流弱,污染物难于向湾外扩散,其物理自净能力差,湾内海水自净主要取决于生化降解.在吐露港海区与沙头角海区,污染排放较大,水深较小,海水难于交换,容易受到污染.

| Abstract: | Combined with estimation of the discharge fluxes of pollutant sources and statistical analysis of the pollutant concentration,this paper employed a 3D numerical model to simulate the pollutant transport and seawater exchange processes in the Dapeng Bay.The model results were utilized to calculate the seawater exchange rate and self-exchange period,and to analyze the contributions of seawater exchange and bio-chemical degradation to the self-purification in the bay.It was difficult for the pollutants inside ... |
