| 摘 要： | 针对潮白河水资源过度开发导致的生态与环境问题,从生态流量的视角进行分析,以潮白河控制性水文站———戴营、下堡站47年(1956年-2002年)的实测日径流资料为基础,利用水文指标法(IHA)及范围变化法(RVA)计算潮白河流量均值、极值及其发生时间、频率、历时和变动率等5组33个指标,对比分析人类活动影响较小的参照期(1956年-1974年)与人类活动影响强烈的影响期(1975年-2003年)的系列水文指标的变化,分析影响期内潮白河流量与目标范围的差距,明确生态流量的恢复目标,提出了实现恢复目标的保障措施。 |

| Abstract: | In order to protect and rehabilitate the health of the riverine ecosystem in the Chaobai River,the Indicators of Hydrologic Alteration method(IHA) and Range of Variability Approach(RVA) were used to calculate the characteristics of hydrological indices in 5 groups including the average streamflow,extreme value and its occurring time of streamflow,frequency and duration of pulse flow,and variation rates of streamflow based on the daily streamflow data at the Daiying and Xiapu hydrological stations from 1956 to 2002.The hydrological indices were compared between two time periods.The first one was from 1956 to 1974,which was characterized by little effects from human activities;whereas the second one was from 1975 to 2003,which was characterized by intense effects from human activities.The differences between the actual value and target range of streamflow were analyzed for the intense human activities time periods.Furthermore,this paper proposed some specific safeguard measures for achieving the restoration objectives. |
