摘　　要：以高邮灌区为例,采用水文-水动力模型,研究稻田控制排水措施对河道洪峰流量、水位和洪水过程的影响。结果表明,雨前通过控制灌溉适当降低田间水位可减轻稻田出流峰值,随着稻田控制水位的增加,稻田径流峰值逐渐降低。通过稻田控制排水,可降低田间出口峰值流量,改变灌区河道洪水过程,降低河道洪峰流量和水位,减轻灌区内部以及附近河道的防洪压力。Taking Gaoyou Irrigation District as an example,a hydrological hydrodynamic model is used to study the impact of paddy field controlled drainage measures on the peak flood flow,water level,and flood process of the river channel.The results indicate that reducing the field water level appropriately by controlling irrigation before rain can alleviate the peak runoff of paddy fields.As the control water level of rice fields increases,the peak runoff of paddy fields gradually decreases.By controlling drainage through paddy field,the peak flood flow at the field outlet can be reduced,the flood process in the irrigation area can be changed,the peak flood flow and water level of the river can be reduced,and the flood control pressure inside and near the irrigation area can be alleviated.
