摘　　要：以淮河流域沙颍河槐店闸的试验为基础,建立闸坝调控作用下的二维水动力污染物迁移模型,通过数值模拟研究闸坝调控对重污染河流水质水量的作用。结果表明,闸坝的存在对河流水环境系统具有一定的负面影响,但可通过合理的闸坝调控、闸前水位调整和控制闸坝下泄流量改变河流水体中污染物的时空分布,减少突发性水污染事故的发生,从而为淮河流域闸坝群水质水量联合调度、改善水生态环境的研究提供技术支持。Based on the experimental data of Huaidian dam of Shayinghe river in Huaihe river basin,two-dimension hydrodynamic model for contaminant transport is set up.The influence of dam regulating on water quality and quantity in heavy pollution river is studied with numerical simulation.The results show that dam has some negative impacts on water environment and ecosystem of river;but the spatio-temporal distribution of pollutant in water body can be improved by dam operation,water level adjustment before the dam and dam discharge control so that it decreases the sudden water pollution accidents.The study can provide technical support for study of dam joint operation of water quality and quantity and improving water environment and ecosystem of Huaihe river basin.
