摘　　要：以长江中下游Z市在长江引清通道Y河新建的应急水源地为例,根据现状地表水质情况以及在应急供水时形成封闭水体的条件下,通过水动力模型、对流扩散模型、常规水质模型和富营养化模型,模拟各种水文、气象条件下水体的流场分布、流速大小和方向、污染物迁移转化及水生生态演变规律,对Y河的富营养化趋势进行预测,根据预测结果提出引江调度方案,为保障应急水源地的水质安全等提供了依据和技术支撑。River Y, a clean water channel at the middle and lower reaches of the Yangtze River is an emergent water source of City Z. Under the conditions of current surface water quality and water body closure during emergent water supply, using models of hydrodynamics, convection diffusion, conventional water quality and eutrophication, water flow field distribution, flow speed and direction, migration and transformation of pollutants and hydrarch succession under different hydrologic and climatic conditions were simulated to predict the eutrophic trend of River Y. According to the prediction results, the schedu- ling scheme for diversion of water from the Yangtze River was proposed to provide the basis and technical support for guaranteeing the safety of emergent water source.
