摘要
利用胶州湾海域成熟的COD平流-扩散输运模型,对胶州湾东岸典型河(海泊河、李村河和娄山河)口区COD响应系数进行了系统的计算和分析。结果为:海泊河、李村河和娄山河口区沿河道主流向,离岸方向海水COD的响应系数在潮周期内随着潮波变化而变化,不同空间点出现最大值的时间不同,变化的幅度范围也不同,李村河和海泊河口区海水COD响应系数变化幅度明显,娄山河口区变化微小;三个河口区COD响应系数随离开河口距离的增大呈幂函数形式下降,水体活跃大小次序为:海泊河口>李村河口>娄山河口;胶州湾中部海水COD对海泊河、李村河和娄山河口的响应系数基本上没有明显差异。
The response coefficients of COD in typical estuaries(Haibo estuary,Licun estuary and Loushan estuary) of Jiaozhou Bay are calculated and analyzed systemically using the advection-dispersion numerical model of COD.The results show that the response coefficients along the shore and off the shore in three estuaries are changed regularly with the variety of the tide in two periods,the time of the maximum is different for the different positions,as well as extent,which is bigger in Haibo estuary and smaller in ...
