摘　　要：城市河道水体透明度是影响水体感官好坏的重要因素,针对苏州城市中心区河道水体透明度不高的问题。采取同步原型观测获取实测基础数据,基于ICM水动力-水质数学模型建立了苏州城市中心区河道在不同引水规模条件下水体透明度反演计算模型,并且结合原位清水置换实验模拟清水置换率与透明度关系,利用水质数学模型模拟预测多种引水规模下苏州城市中心区河道水体透明度情况,为清水工程的实施提供了技术支撑。通过模拟预测可以确定引水量最佳规模选择为150万m^3/d。此种引水规模条件下,引水1.5天能实现苏州城市中心区城市河道50cm左右的透明度,引水2天能够实现苏州城市中心区城市河道80-90cm左右的透明度,引水3天能够实现苏州城市中心区城市河道100cm左右透明度。The transparency of water in urban river channels was an important factor affecting the sensory quality of water. In view of the problem of low transparency of water in the center of Suzhou city, the synchronous prototype observation was taken to obtain the measured basic data. Based on the ICM hydrodynamic-water quality mathematical model ,the water transparency inversion model of river channel in Suzhou urban center was established under different water diversion scale, and the relationship between clear water replacement rate and transparency was simulated by in situ water displacement experiment, and water quality mathematical model was used to simulate and predict The water transparency of river channel in Suzhou city center area under the water diversion scale provides technical support for the implementation of clear water project. Through simulation, it can be concluded that the optimal diversion quantity is 1.5 million m3/d. The water diversion can achieve the transparency of about 50cm in the urban river channel of Suzhou city center within 1.5 days of water diversion. The diversion can achieve the transparency of about 80-90cm in the urban river channel of Suzhou city center for 2 days. The water diversion can achieve Suzhou urban center area for 3 days Urban river about lOOcm transparency.
