| 摘 要： | 建立了巢湖一维水质模型DYRESM-CAEDYM,并利用2005年的实测水质、水文、气象等数据对模型进行了参数率定,确立了适用于巢湖水环境特征的水质模型参数. 应用该模型模拟了调水对巢湖TN,TP和Chl-a指标的影响,结果表明,年调水量为9.57×108 m3时可使巢湖的ρ(TN)和ρ(TP)下降约16%和19%,ρ(Chl-a)峰值从51.42 μg/L降至38.96 μg/L,ρ(Chl-a)超过30 μg/L的天数从26 d减少到16 d,对巢湖夏季蓝藻暴发具有一定的缓解作用. 对比分析了流域污染综合治理对巢湖水环境的改善效果,结果显示,如果各支流的入湖污染负荷能够削减5%,同时开展底泥清淤工作,可使巢湖的ρ(TN)和ρ(TP)得到较大程度的改善,与没有治理的情况相比分别降低约24.9%和33.3%,使巢湖夏季的ρ(Chl-a)峰值从51.42 μg/L降至32.72 μg/L,ρ(Chl-a)超过30 μg/L的天数从26 d减少到7 d.

| Abstract: | A one-dimensional water quality model DYRESM-CAEDYM for Chaohu Lake was established,and the parameters of the model were calibrated by monitoring data including water quality,hydrology and meteorology in 2005.Then,the parameters of a water quality model applicable to the water environment of Chaohu Lake were determined.The model was applied to simulate the influence of water transfer from the Yangtze River to Chaohu Lake on TN,TP,and chlorophyll a mass concentrations in Chaohu Lake.The simulated results sho... |
