摘　　要：汛限水位是协调水库运行管理中防洪与兴利矛盾的关键参数之一,也是实现洪水资源安全利用的重要指标。以于桥水库为例,研究以累积净雨为判别洪水指标的预报调度方式及规则,分析了防洪预报调度方式的运行机理及其对水库调度的影响,并采用防洪风险和蓄水效益综合评价体系,确定出相对合理的汛限水位控制值。研究结果表明,采用合理的预报调度方式和综合评价体系,可经济安全地抬高汛限水位,实现汛期洪水资源的安全利用。As a key parameter coordinating flood control and impounding, the limited level of reservoirs during the flood season is a crucial factor of flood resources utilization. With an example of the limited level analysis of Yuqiao reservoir during the flood season, a method of forecast operation judging the flood frequency by accumulated runoff is proposed to elevate the limited level of reservoirs during the flood season. Meanwhile, to utilize flood resources in security, a comprehensive evaluation system is presented to obtain an optimum limited level of reservoirs during the flood season including risk rate, damaged degree, renew degree and impounding benefit.It is shown that different flood frequency judgment indexes influence variously the impounding capacity of reservoirs, and forecast operation mode and comprehensive evaluation system are important for the safe utilization of flood resources during the flood season.
