基于差积曲线法的龙羊峡水库年兴利库容及多年调节库容计算

Calculation of Annual Beneficial Reservoir Capacity and Over Year Regulation Storage Capacity of Longyangxia Reservoir Based on Different Curve Method

龙羊峡水库是黄河上游具有多年调节作用的“龙头”水库。采用基于长系列的差积曲线法计算1957—2016年逐年所需的兴利库容和多年调节库容,指导编制龙羊峡水库调度图,对多年调节水库的调度提供有力的参考依据。

Longyangxia Reservoir is the“leading”reservoir with multi-year regulation in the upper Yellow River.In this paper,the different curve method based on long series is used to calculate the annual required beneficial reservoir capacity and over year regulation storage capacity from 1957 to 2016,which can be used to guide the preparation of operation chart of Longyangxia Reservoir and can provide a strong and reliable reference for the operation of multi-year regulating reservoir.
