为研究东江新丰江水库、枫树坝水库和白盆珠水库对水库下游河流水文情势的影响,以河源和博罗水文站为研究站点,利用多年的实测逐日流量数据,采用变化范围法(RVA)计算分析了天然状况和水库修建后的水文特征值的变化,结果表明,新丰江和枫树坝水库建设对河源站附近河段水文情势的影响属于高度改变,三大水库对博罗站附近河段水文情势的影响也属于高度改变. In order to study the influence of Dongfeng Xinfengjiang Reservoir, Fengshuba Reservoir and Baipenzhu Reservoir on the hydrological regimes of the rivers downstream of the reservoir, Heyuan and Boluo hydrological stations were used as research sites. Based on the measured daily measured data and the RVA ) Calculated and analyzed the changes of natural conditions and hydrological characteristics after the construction of reservoirs. The results show that the influence of Xinfengjiang and Fengshuba construction on the hydrological situation near Heyuan Station is highly varied. The influence of the hydrological situation in the nearby reach is also highly variable.
