摘　　要：本文探讨一种新型的、动态的汛限水位控制方法,并以此方法对密云水库汛限水位进行计算分析。滑动汛期水位在多年资料基础上,通过统计汛期中每日为起点的最大来水量,求出固定频率的设计来水量,选择合适的典型洪水过程线进行调洪计算后得到每天的汛限水位。相对于常规的年最大法,动态汛限水位有效地节约了水资源。A new dynamic way to analyze the flood control level of Miyun reservoir is presented in this paper. By use of many years＇ hydrologic data, the max. water quantity dated from every day may be counted in every year＇s flood season, and the designed water quantity corresponds to the definite frequency. Finally, every day＇ s flood control level can be found by routing use of appropriate typical flood hydrograph.. Compared with the conventional annual maximum method, the water resource can be availably saved by the dynamic flood control level.
