摘　　要：采用三角形网格的分布杂交法,以变边界模型建立起威海及烟台南部近岸海域纯潮作用下的COD浓度平流——扩散模型。计算出烟台、威海南部近岸海域COD浓度分布现状并绐出各污染源的最大允许排放量,并对未来状况浓度分布作出了预测。Using the fractional hybrid method with triangle grids, this paper constructs a convection-dispersion model of COD concentration with varied boundary which is affected by the tidal current in the offshore area of southern Yantai and Weihai.The present distribution of COD concentration is given and the maximum permited discharge amount of each pollution source is obtained from the result of calculation. Finally, the distribution of COD concentration in the future is predicted.

关 键 词：烟台、威海南部 近岸海域 COD 平流——扩散模型 最大允许排放量 浓度预测
