摘要
在实验室条件下，模拟换水工程，采用静态浸泡实验，研究比较了不同引水量及温度对水体化学需氧量（COD）、总磷（TP）的影响，探讨了引江入湖修复城市内湖生态环境方案的可行性。结果表明：引水对改善磁湖水质有一定作用，从改善水体COD、TP考虑，最佳引水量为湖水、江水1：（1-1．5）比例引水。由于磁湖内源污染严重，引水会造成底泥营养物的强烈释放，单纯引水难以达到最大的环境效益和投资效益，建议采取引水与内源污染治理并重的方案对磁湖进行生态环境修复。
Under the static immersion simulated test in labs, effects of the difference amount of di- verting water and temperature on chemical oxygen demand （COD）、 total Phosphors （TP） of water was studied and feasibility of Ecological restoration of Urban Inland Lake by Introduction of River Water into Lak was discussed. The results showed that only cosidered with COD ,TP of water, The suitsbal ratio of diverting water was 1： （1-1.5） for the water of the Yangtze River and Cihu lake. One-sided di- version of river water to improve the eco-environment of Lake was too difficulity to obtain maximum environmental efficiency and investment returns, mainly due to a serious inner pollution of Cihu lake.a newly plan was suggested for Ecological restoration of Cihu Lak combining strict control of inner pol- lution with a programme of.diverting water from the Yangtze River into Cihu lake into into Cihu lake.
