• 摘要：根据暴雨径流污染物浓度变化特点,采用最小二乘法对暴雨期间污染源各监测数据进行回归分析处理,对湖底糙率采用自动调整处理,建立了湖泊暴雨径流水质模型。对滇池湖泊某次暴雨过程的总磷和总氮进行了模拟研究,计算结果表明,该模型应用于滇池湖泊是成功的。

• Abstract：Water quality monitoring data collected during storm events were analyzed using least square technique to develop a water quality model for storm runoff to lakes. Limbic botton roughness automatic adjustment was performed during the modeling. The model was applied to total P and N concentration in Lake Dianchi before, during and after the rainstorm event.
