摘要
青海境内黄河梯级电站分布在唐乃亥水文站和循化水文站之间，利用实测和还原后的径流资料，定量分析了青海境内已建梯级电站对黄河年径流的影响。受到龙羊峡等水库调节影响，径流年际年内分配趋于均匀化，将汛期（7～10月）22．6％的水量经调节转移到11月～12月和次年1～5月，并具有多年调节特性。
The cascade hydropower stations of the Yellow River in Qinghai Province is located between the Tangnaihai and Xunhua Hydrology Station, by the observed data and restored data of runoff, the author analyzed the influence of annual runoff by the constructed cascade hydropower station in Qinghai Province quantitatively. Regulation by the Longyangxia Reservoir, annual distribution of runoff tends to uniformity, 22.5 percent of the water- quantity of flood season（from July to Oct. ） regulated to Nov. Dec. and Jan. to May next year, and the reservoir has multi - regulating characteristics.
