摘　　要：为了分析论证内秦淮河现状引调水的效果和存在问题,采用MIKE11模型对河网进行概化,建立了一维河网数学模型。以枯水期为例,选取6个控制断面的氨氮浓度为水质评价指标,运用验证后的模型对内秦淮河现状引调水的效果进行模拟与计算。结果表明:现状条件下,内秦淮河水体污染较严重,水源地水质和引水流量达不到引水冲污的要求,需改善水源地水质,加大引水流量;每条引调水线路均存在引水盲区,引水冲污应采取4条线路联合引调水的方式。In order to analyze the effects and existing problems of water diversion in Inner Qinhuai River, a river network was generalized by MIKEll model, and a one-dimension mathematical model of the river network was set up. Taking the typical dry season as an example, NH3-N concentration of six control sections were selected as the assessment index of water quality, and a validated model was applied to simulate and calculate the effects of water diversion. The results show that the Inner Qinhuai River is seriously polluted, and the water quality and the flow of water diversion are not up to the requirements of flushing pollutants, and the water quality in water source area should be improved and the flow of water diversion should be increased. There are blind spots of water diversion in every water diversion line, and we should take 4 lines of diverting water jointly to flush pollutants.
