摘　　要：以溪洛渡水库上游8座关键控制性水库作为研究对象,在分析其整体调节性能基础上,探讨上游水库群调蓄对溪洛渡水库入库流量的影响。结合溪洛渡水库调度期划分,对各分期影响进行分析。考虑水库调节性能不同,采用2018年7月的日洪水过程及11月金沙江中游流域日回蓄过程作为典型案例进行分析。研究表明,上游水库群调蓄流量占溪洛渡入库总流量的20%左右,呈现出"汛期拦蓄,枯期补水"的调蓄过程。雅砻江流域中长期调蓄规律较为明显,金沙江中游流域日尺度调蓄影响较为显著。相关研究成果有助于溪洛渡水库实际调度工作的开展。Eight key control reservoirs in the upstream of Xiluodu Reservoir were taken as the research object.Based on the analysis of its overall regulation performance,the adjustment and storage effect of the reservoir group on the inflow of Xiluodu reservoir was discussed.The degree of impact was analyzed for different operational phases of the Xiluodu Reservoir.In view of the different regulation performance of the reservoirs,the daily flood process in July 2018 and the daily recovery process in the middle reaches of the Jinsha River in November 2018 were used as typical cases for analysis.The research shows that the storage and regulation volume of the upstream reservoirs accounts for about 20%of Xiluodu’s inflow volume,and the process shows a pattern of"storage during flood season and replenishment during dry season".The long-term regulation of storage exhibits more obvious effect in the Yalong River basin,while the daily scale regulation has a more significant impact in the middle reaches of the Jinsha River.The results are helpful for the actual dispatching of Xiluodu Reservoir.
