【摘要】 以胶洲湾为例 ,采用分步杂交法 ,在已建潮流场的基础上 ,建立胶州湾海域二维变边界对流———扩散数值模型 ,选COD为有机污染的指标因子,并视为保守元素。对不同的填海方案 ,造成胶州湾内COD浓度场的改变及污染物通量的变化 ,进行计算分析,并给出对污染物输运影响数值研究的初步结论。更多还原

【Abstract】 A two dimensional varied boundary pollutant transportation numerical model of Jiaozhou Bay is established by using the split steps finite element method .Based on the computed tidal current field, it chooses COD as a pollutant factor.Predictions are made according to several sea-filling plans.The impact of COD distribution and pollutant influxes are obtained ,with giving introduction summing-up impact of pollutant transportation.更多还原
