摘要：
Based on the daily average runoff data of Huangchuan and Huaibin hydrological stations in Huaihe River Basin from 1952 to 2012, the moving average method and Mann-Kendall test were used to analyze the interannual variation of Huanghe River runoff, the concentration degree, concentration period, non-uniformity coefficient and extreme value ratio were used to analyze the annual distribution variation of Huanghe River runoff, and the IHA method was used to analyze the change of Huanghe River hydrological regime before and after the construction of Pohe Reservoir. The results show that Pohe Reservoir has no significant impact on the interannual runoff variation trend of Huanghe River. However, Pohe Reservoir significantly influences the annual distribution of Huanghe River runoff, where in the annual distribution tends to be uniform and the stability of the watershed ecosystem has been improved. © 2021, Editorial Board of Water Resources Protection.
