摘　　要：本文以浑江流域2010年两场洪水为研究背景,分析桓仁水库上游中小型水库实际调度对桓仁水库入库洪水的影响,得出以下结论:在2010年7月28日—8月3日7天洪水过程中,上游4库的调度运行使桓仁水库入库水量增加1306万m3,占桓仁水库同期来水量的1.12%,整个洪水期,上游水库的调度使桓仁水库入库总水量有所增加。在2010年8月27日—9月2日7天洪水过程中,上游4库的调度运行使桓仁水库入库水量减少670万m^(3),占桓仁水库同期来水量的0.71%,上游水库的调度使桓仁水库入库总水量有所减少。应用此研究成果可提高浑江流域水文预报的精确度,研究成果为同类调度提供参考。This paper,set against the backdrop of two flood events in the Hunjiang River Basin in 2010,analyzes the impact of the actual scheduling of small and medium-sized upstream reservoirs on the inflow floods at the Huanren Reservoir.The following conclusions are drawn:during the 7-day flood event from July 28 to August 3,2010,the operation of the upstream four reservoirs increased the inflow volume to the Huanren Reservoir by 13.06 million cubic meters,accounting for 1.12%of the concurrent inflow to the Huanren Reservoir.Throughout the entire flood period,the scheduling of the upstream reservoirs resulted in an overall increase in the total inflow volume to the Huanren Reservoir.However,during the 7-day flood event from August 27 to September 2,2010,the operation of the upstream four reservoirs reduced the inflow volume to the Huanren Reservoir by 6.7 million cubic meters,accounting for 0.71%of the concurrent inflow to the Huanren Reservoir.The scheduling of the upstream reservoirs led to a decrease in the total inflow volume to the Huanren Reservoir during this period.These research findings can enhance the accuracy of hydrological forecasting in the Hunjiang River Basin and provide a reference for similar scheduling practices.
