摘　　要：为研究突发性水污染事件及水利工程调度对河流水量水质的影响,文中采用MIKE 11软件建立了辽河干流铁岭-六间房一维水环境数学模型,选取多个水量水质监测断面,模拟突发水污染事故发生期间的水动力及水质状况,并根据现有水利工程和建筑物分布开展优化调度分析,确定各方案的防治效果,提出综合建议。结果表明,模型具有较高精度,可用于辽河干流的突发水污染事件研究。研究成果能够对辽河干流水量水质进行复现,可用于应急环境下的水量水质预测,并为突发水污染事件下的生态调水应急方案提供理论依据。In order to study the impact of sudden water pollution events and water conservancy project scheduling on the water quantity and quality of rivers,a one-dimensional water environment mathematical model of Tieling-Liujianfang in the Liaohe River main stream was established by using MIKE 11 software.Multiple water quantity and quality monitoring sections were selected to simulate the hydrodynamic and water quality conditions during sudden water pollution accidents.According to the distribution of existing water conservancy projects and buildings,the optimal scheduling analysis was carried out to determine the prevention and control effects of each scheme,and comprehensive suggestions were put forward.The results show that the model has high accuracy and can be used for the study of sudden water pollution events in Liaohe River.The research results can be used to predict the quantity and quality of Liaohe Main Stream in emergency environment,and provide theoretical basis for ecological water transfer emergency plan under sudden water pollution events.
