摘　　要：为保证奥林匹克水上公园满足相关水质标准,开展奥林匹克水上公园水环境污染防治研究非常必要。为评估污染防治方案的效果,构建了水上公园水质生态数学模型,主要模拟指标为TN,TP,BOD_5,DO,叶绿素以及藻类,通过2008年实测水质资料进行了模型的验证和率定,对各污染防治方案的效果进行模拟。模拟结果表明:模型较好地模拟了水质和藻类动态变化;水处理站运行和地下水补水方案,对各污染物削减以及藻类生长的抑制作用明显。To ensure the water of olympic rowing-canoeing park to satisfy the relative water quality standard, it is necessary to carry out the research on water environment pollution prevention. To evaluate the progress of the pollution control programs, the water quality and ecological model has been set up in the studied area. Main variables such as total nitrogen, total phosphorus, dissolved oxygen, biological oxygen demand, chlorophyll and algae biomass were included in the modeling. The observations of hydrology, water quality and biology in 2008 were applied to the modeling calibration and validation. Furthermore, the model was used for the overall impact of the proposed pollution control scenarios. The modeling result is in good coincide with the observations. It has been found that the pollutants concentrations and chlorophyll in the water susceptible to algal blooming would reduce significantly following the implementation of the program, such as the operation of the treatment plant and the supplement of the groundwater.
