摘要
计算葛洲坝1982—2014年的入库流量和下泄流量的IHA指标,采用RVA变化范围法分析考虑葛洲坝水库的修建运行对水文情势的影响。结果表明:葛洲坝水库为日调节水库,对月流量、极端水文状况及出现时间、高流量和低流量脉冲次数和平均历时改变较小,对涨落水指标改变较大,尤其是对流量逆转次数和日增长率改变明显。
This paper calculated the IHA index of inflow and discharge of Gezhouba project from 1982 to 2014,and the range of variability approach(RVA) was used to analyze the impact on hydrological regime which was only considered by the construction and operation of Gezhouba reservoir. The results showed that Gezhouba reservoir was a daily regulating reservoir. The alteration of monthly flow, extreme hydrological regime&occurrence time,pulse times and average duration(high flow&low flow) is small,but the flood fluctuation index changed greatly, especially the number of reversals and daily growth rate.
