| 中文摘要: |
| 为了响应习近平总书记“长江大保护”的号召，九江市两湖（甘棠湖和南门湖）拟开展岸上截污、水生态修复和活水畅流工程等一系列水环境综合治理工程，以期使湖区内主要水质评价指标达到Ⅳ类水质目标.利用MIKE 11、MIKE 21及MIKE FLOOD建立了水动力水质耦合数学模型，对两湖的流场及污染物浓度场进行模拟分析，预测上述水环境综合治理工程的水质目标可达性.研究表明：工程实施后，两湖各水质指标的空间达标率都大于90%，晴天的水质空间达标率大于雨天；全年降雨期（降雨量大于31mm/d）中约有8.63%的时段存在短暂的水质超标，经过若干天的恢复期主要水质评价指标可重新达标. |

| In response to the call of General Secretary Xi's“Yangtze River Protection”，two lakes in Jiujiang（Gantang lake-Nanmen lake）are planned to carry out a series of water environment comprehensive treatment projects including shore interception，water ecological restoration and live water flow engineering，in order to achieve the Class IV water quality target.The mathematical model of hydrodynamic and water quality was established by MIKE 11，MIKE 21 and MIKE FLOOD.The flow field and pollutant concentration field of the two lakes were simulated and analyzed，and the water quality target accessibility of the water treatment project was evaluated.The research shows that after the implementation of the project，the spatial compliance rate of each water quality index of the two lakes is up to 90%，and the water quality compliance rate of sunny days is greater than rainy days；there are about 8.63%of the rainfall period （rainfall more than 31mm/d）exceed the water quality standard，which can re-standard after several days of recovery． |
