摘　　要：通过对黄石市青山湖1#湖清淤后的水质情况进行监测,对照清淤前数据,分析清淤改造工程对青山湖1#湖水质的改善程度。虽然总氮、总磷和COD Cr的浓度在清淤过程中有所下降,但是清淤过程不可避免的会造成湖底底泥扰动,使沉积在底泥中的总氮、总磷及重金属重新释放到湖水中,从而导致水质在短时间内变差。因此,为巩固清淤成果,应持续对湖水水质进行监测及评价。Based on the monitoring of Qingshan NO. 1 Lake of Huangshi,the improvement degree of water quality was analyzed after the sediment dredging project by comparing with the datas before the project. Though the concentration of TN, TP and CODcr declined during the dredging, the project inevitably produced the sediment disturbance, which released the TN ,TP and heavy metals into the lake again and resulted in the poor quality of the water quality in such a short tme. Accordingly, water quality should continuously be moni- tored and assessed in order to consolidate the dredging results.
