    摘要:

    基于淮河流域潢川、淮滨两个水文站1952—2012年的日平均径流数据,采用滑动平均法和Mann-Kendall检验方法分析潢河径流年际变化,采用集中度、集中期、不均匀系数和极值比分析潢河径流年内分布变化,采用IHA法分析泼河水库建成前后潢河河道水文情势的变化。结果表明:泼河水库未对潢河年际径流变化趋势产生显著影响,而对潢河径流的年内分布影响则十分明显,年内分配趋于均匀化,流域生态系统的稳定性有所提升。

    Abstract:

    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.
