摘　　要：三峡水库自2003年蓄水以来,库区的产汇流规律及径流特性发生了较大改变。为科学调度三峡水库,充分发挥其综合效益,对比了其入库洪水和坝址洪水的差异,并从洪峰、洪量及峰现时间3个方面分析了两者之间的关系。在此基础上,通过线性回归法,从洪峰、3 d洪量以及7 d洪量3个方面分析了入库洪水和坝址洪水的相关关系。结果显示,相关关系都在0.9以上,表明相关关系较好。The characteristics of runoff in reservoir area of Three Gorges Reservoir have changed greatly since the reservoir is impounded in 2003. In order to scientifically dispatch reservoir operation and give full play to its comprehensive benefits, the differences between reservoir inflow flood and dam site flood are compared, and the relationship between them is analyzed from three aspects of flood peak, flood volume and peak current time. On the basis of this, the quantitative relationship between two floods is analyzed by using linear regression from three aspects of flood peak, 3-day flood volume and 7-day flood volume. The analysis results show that the correlation is above 0.9.
