| 摘 要： | 应用三维水质模型对大连湾中的主要污染物NH3-N的行为进行了模拟,对NH3-N浓度的时空变化规律以及其影响因素进行了研究,选择主要的模型参数进行了灵敏度分析。由空间分布的模拟结果可知,在大连湾,NH3-N浓度主要集中在排污口附近区域,灵敏度分析显示,在排污口区水体的扩散能力对NH3-N浓度的影响较大。由季节变化模拟结果可知,在湾顶部的排污口区NH3-N浓度显示明显的季节变化趋势。在湾中部和朝海边界的湾口区NH3-N浓度较低,变化平缓。模拟结果可以为大连湾的污染控制、水质规划和管理提供科学依据。

| Abstract: | In this paper the WAHMO model was applied and developed to simulate ammonia nitrogen water behavior in Dalian Bay.Beyond the spatial and temporal distribution of ammonia nitrogen,sensitivity analysis was conducted.The major factor controlling the distribution of ammonia nitrogen concentrations in Bay tip was diffuse process.From the simulation results of seasonal changing,it indicated that ammonia nitrogen concentration was low in Bay middle and Bay mouth and changed very slowly.These could be helping in the pollution controlling and water quality managing in Dalian Bay. |
