摘　　要：为了提高水资源利用率,实现洪水资源化,本文针对安康水库工程实例,通过对水库调节性能、6h入库水量预报精度等的分析,提出了基于6h预报径流深的水库防洪预报调度方式,并采用逐级调节法制定了预报调度规则。分别从不同频率、不同典型年和不同起调水位等几个方面,对常规防洪调度和预报调度进行了分析比较,结果表明采用防洪预报调度方式不但有利于水库上下游防洪安全,也有利于洪水资源的利用,其较常规调度规则具有更好的调洪效果。A flood forecast operation scheme was put forward to improve the use of water resources and floodwater resources of Ankang reservoir.This scheme is based on six hours runoff forecast information with consideration of runoff forecast accuracy and reservoir regulation.Forecast operation rules were worked out by a step-by-step regulation method.Flood forecast operation by the new scheme was compared with normal operation for the cases of different flood frequencies,different flood year types and various initial water levels of flood routing.The results indicate that the proposed scheme improves floodwater resources utilization and flood control safety.
