丰、枯水期末蓄水量是影响多年调节水库蓄丰补枯规则的关键要素.以黄河上游龙羊峡水库为研究对象,基于该水库的历史运行资料,考虑水库丰、枯水期的来水量、初始蓄水量等影响,采用多元线性回归方程建立调度函数,推求丰、枯水期水库增补水量,确定水库的丰、枯水期末蓄水量.结果表明:(1)龙羊峡水库丰水期增水量的距平值与来水量的距平值呈显著的正相关性(R2=0.42),枯水期水库补水量的距平值与初始蓄水量的距平值呈显著的正相关性(R2=0.16);(2)由调度函数推求的丰水期增水量与实际增水量的相关性良好(R2=0.62),枯水期补水量与实际补水量相关性也较好(R2=0.38).研究成果可为龙羊峡水库调度规则的建立提供依据,也可为其他多年调节水库的调度提供参考.
Characteristics of Wetness Storage and Dryness Compensation of Longyangxia Reservoir
The water storage at the ends of wet and dry seasons are critical factors influencing the regulations of multi-year regu-lation reservoirs for wetness storage and dryness compensation.The Longyangxia Reservoir,which is located in the upstream of the Yellow River,was chosen as a case study.Considering the influence factors such as the inflow and initial storage of the reser-voir,the study employed historical operation data and the multiple linear regression equation to establish a dispatching function to estimate the supplemental water amount required in wet and dry seasons.Based on the supplemental water amount,the storage at the ends of the two seasons could be determined for the Longyangxia reservoir.The results show that,firstly,there is a signifi-cant positive correlation between the anomaly increased water and the anomaly inflow during the wet period(R2=0.42),and also ob-served between the anomaly supplemental water and the anomaly initial storage during the dry season(R2=0.16).Moreover,the in-creased water derived by the dispatching function demonstrates a strong correlation with the actual increased water during the wet season(R2=0.62),and a similar correlation is observed between the calculated and actual supplemental water during the dry sea-son(R2=0.38).The results could provide references for the scheduling of Longyangxia Reservoir and other multi-year regulation res-ervoirs.
