东平湖作为南水北调东线工程梯级泵站提水的最后一级调蓄湖泊，其水质安全至关重要。借助于地表水建模系统软件 SMS，根据东平湖的地形、植被覆盖和调水流向等进行网格划分，建立二维水流水质模型，模拟了20种工况下湖区的水质状况。结果表明：大汶河入湖流量和 CODCr浓度越大，调水出湖口 CODCr浓度越高，大汶河入湖口污染混合区范围就越大；当大汶河入湖流量小于5 m3/ s、CODCr浓度小于27 mg/ L 时，调水出湖口 CODCr 可以达到Ⅲ类水质标准；当大汶河入湖流量小于10 m3/ s、CODCr浓度小于23 mg/ L 时，调水出湖口 CODCr可以达到Ⅲ类水质标准。
東平湖作為南水北調東線工程梯級泵站提水的最後一級調蓄湖泊，其水質安全至關重要。藉助于地錶水建模繫統軟件 SMS，根據東平湖的地形、植被覆蓋和調水流嚮等進行網格劃分，建立二維水流水質模型，模擬瞭20種工況下湖區的水質狀況。結果錶明：大汶河入湖流量和 CODCr濃度越大，調水齣湖口 CODCr濃度越高，大汶河入湖口汙染混閤區範圍就越大；噹大汶河入湖流量小于5 m3/ s、CODCr濃度小于27 mg/ L 時，調水齣湖口 CODCr 可以達到Ⅲ類水質標準；噹大汶河入湖流量小于10 m3/ s、CODCr濃度小于23 mg/ L 時，調水齣湖口 CODCr可以達到Ⅲ類水質標準。

As the last impounded lake for cascade pumping station pumping in the East Route of the South-to-North Water Transfer Project,Dong-ping Lake’s water quality security is crucial. Based on the surface water modeling system software SMS,the paper set up two-dimensional flow-pol-lutant mathematical model in Dongping Lake according to Dongping Lake’s characteristics such as terrain,vegetation coverage and so on;then sim-ulated Dongping Lake’s water quality conditions under 20 simulated conditions. Analytical results indicate that the outflow concentration of CODCr and characteristic scale of the pollution mixed zone of CODCr exceeding type Ⅲ water quality standard become larger with the increase of the inflow discharge and the inflow concentration of CODCr of Dawen River;when the inflow discharge of Dawen River is less than 5 m3 / s and the inflow con-centration of CODCr is less than 27 mg/ L as well as when the inflow discharge of Dawen River is less than 10 m3 / s and the inflow concentration of CODCr is less than 23 mg/ L ,the water quality of outflow area will meet grade Ⅲ standard.
