摘　　要：根据白鹤滩水电站坝址长系列径流资料,对电站径流年内、年际变化规律以及洪水特性进行分析研究的结果表明,其坝址径流各年代均有一定变化,但无明显周期性规律,2006年之后进入枯水段;年内分配方面,受降水特性影响,年径流主要集中在6月~10月,占年径流的75%左右。研究成果对白鹤滩水电站施工安全有重要作用,同时对水库运行以及梯级水库调度方式具有指导意义。Based on the long series of runoff data at the dam site of Baihetan Hydropower Station, the change rules of annual and inter-annual rnnoff as well as the characteristics of floods for the power station are analyzed. The results show that, （a） the runoff at clam site clam has a certain change in each decade, but there is no obvious periodicity, and after 2006, it enters into dry years; and （b） the annual runoff distribution is mainly affected by preeipitation characteristics, and the annual runoff mainly concentrates in June to October which accounts for about 75% of the annual runoff. The research results are important to the construction safety of Baihetan Hydropower Station, and have great significance for the operation of Baihetan Reservoir and the scheduling mode of cascade reservoirs.
