摘　　要：水量平衡是水文水资源领域最基本的原理,通过研究区域水量平衡,可以确定区域各水文要素之间关系、合理认识和评价区域水资源、指导水资源优化配置。基于水量平衡原理,分别采用平衡差和区间降雨径流系数对郁江流域各水电站、水电站区间进行计算分析,发现在实际运行中存在明显水量不平衡现象。该现象的存在,对梯级水电站的防洪度汛、来水预测预报、联合优化调度等造成一系列的影响,并影响电站的经济效益和安全生产。通过对水量平衡各要素及其计算过程的分析结果看,郁江流域水电站水库之间水量不平衡的主要原因是运行多年的特性曲线发生了改变。Water balance is the most basic principle in the field of hydrology and water resources.By studying regional water balance,this paper can determine the relationship between regional hydrological elements,reasonably understand and evaluate regional water resources,and guide the optimal allocation of water resources.Based on the principle of water balance,the balance difference and interval runoff coefficient are used to calculate and analyze each hydropower station and hydropower station interval on Yujiang River basin,and it is found that there is an obvious water imbalance phenomenon in actual operation.The existence of this phenomenon has caused a series of impacts on flood control,incoming water prediction and forecast,and joint optimal operation scheme,and affects the economic benefits and safety production of the stations.By analyzing the elements of water balance and its calculation process,the main reason for water imbalance is that the reservoir characteristic curve of the hydropower station has changed over the years of operation.
