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,主要模拟指标为总氮,总磷、五日生化需氧量、溶解氧、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。For the purpose of evaluating the progress of pollution control measures,an ecological model has been set up in the study area.Main variables such as total nitrogen,total phosphorus,dissolved oxygen,biological oxygen demand,chlorophyll and algae biomass were included in the modelling.The observations in terms of hydrology,water quality and biology in the year 2008 were used to modelling calibration and validation. Furthermore,the model was applied to the simulation of overall effects of proposed pollution control scenarios. The modelling result was in good coincidence with the observations.It has been found that the pollutant concentrations and chlorophyll a level in the water susceptible to algal blooming would reduce significantly following the implementation of measures such as the operation of water treatment facilities and the groundwater recharge.
