摘　　要：水库兴利调节计算是开展水资源论证的核心工作,而对于缺少入库径流观测资料的供水水库而言,来水量计算是进行水库兴利调节计算的关键步骤。针对缺资料地区水库实际情况,基于降雨径流系数法推求入库径流量,并综合采用水文比拟法、水量平衡法等多种方法合理确定径流系数。根据水库调度运用原则按照长系列时历法以旬为单位进行水资源供需平衡调节计算,得到了不同取水规模下的调节计算成果,评价了不同取水规模的供水保证程度及对灌溉、发电等其他用水户的影响,以达到对水资源合理分配及优化的目的。The calculation of reservoir utilization and regulation is the core work of water resources demonstration,however,for water supply reservoirs without inflow runoff observation data,the calculation of inflow is the key step in the calculation of reservoir utilization and regulation.According to the actual situation of reservoirs in the area which lack of data,the inflow runoff was calculated based on the rainfall runoff coefficient method,and the runoff coefficient was reasonably determined by several methods such as hydrological analogy and water balance.According to the principle of reservoir dispatching,the balance of supply and demand of water resources was calculated in a ten-days basis according to the long series of time calendars.The results of regulation calculation under different water intake scales were obtained,the guarantee degree of water supply of different water intake scale and its influence on other water users such as irigation and power generation were evaluated,so as to achieve the purpose of rational allocation and optimization of water resources.
