摘　　要：在充分认识闸控河段水动力与水质因子变化特征的基础上,以沙颍河干流上的槐店闸为研究对象,研制了考虑水闸调控作用的水动力模型和考虑内源释放的水质迁移转化模型,结合实测资料对模型进行了验证;设计了多种水闸调度情景,对各情景下的水质浓度时空变化过程进行了模拟,进而构建了水质浓度变化率与闸门开度、闸门开启个数等调控因子的对数关系式。结果表明,本文所建立的量化关系能够反映闸门调度对水质浓度变化的影响,有助于实现对水闸的科学调度。This study develops a hydrodynamic model for sluice operation action and water quality transportation and a transform model with endogenous substance exchange action for application to the Huaidian sluice on the Shaying River, considering hydrodynamic and water quality factors in the reaches controlled by the sluice. These models were verified with the data observed in a field monitor experiment and the results are reasonable. For various scenarios of sluice operation, the temporal and spatial variations in water quality concentration were simulated. Logarithmic expressions of the relationship between the calculated concentration change rate and operation factors （such as gate opening and number of gates） were established. It is shown that these quantitative relationships reflect the influence of sluice operation on water quality concentration. This study lends a support to operation of river sluice with environmental concerns.
