摘　　要：文章以沙颍河干流上的槐店闸为例,在研制水闸调度影响模型(由考虑水闸影响的一维水动力模型和考虑底泥作用的一维水环境数学模型组成)基础上,设置不同的水闸调度情景,并对各种情景进行模拟计算及对比分析,进而评估水闸调度对河流水质变化的影响。通过模拟分析发现:水闸调度使河道的水位、流量及流速等水动力学条件有明显的变化,从而对河流水质产生一定的影响。Taking Huaidian Dam gates on Shayinghe River as example,a control model of dam operation impact on water quality and quantity was developed,considering a one-dimensional hydrodynamic model on dam scheduling and a one-dimensional water environment model of sediment.Different dam scheduling scenarios were set and modelled,and simulation results were analyzed comparatively to evaluate the influence of dam regulation on spatial and temporal distribution of pollutants concentration in river.Through simulation analysis,it was found that dam scheduling not only affects the river hydrodynamic conditions significantly,but also has some effect on temporal distribution of pollutants concentration in river.
