| 研究“引黄入冀补淀工程”引黄口重点断面的径流情势变化及其成因，对促进引黄口重点断面水资源管理和该工程建设水生态效益的发挥具有参考价值。本文采用水文变异指标法/变化范围法（IHA/RVA法），对1958-2005年工程建设影响前、2006-2016年工程建设影响后2个阶段的33个单项水文指标及改变度进行对比分析，掌握引黄口重点断面的径流情势变化情况；并基于6种Budyko假设公式，量化分析气候变化和人类活动对径流改变的贡献率。结果显示：8项单项水文指标达到67%以上的高度改变，整体径流情势改变度达到61.72%；气候变化和人类活动对径流变化的贡献率平均值分别为41.79%和58.21%。人类活动是影响引黄入冀补淀工程引黄口重点断面径流情势变化的主要因素。 |

| The "Water diversion project from the Yellow River to Hebei Province" is important for ensuring the water supply in the Xiong’an area, and impacts runoff in a key section of the water diversion project. The objectives of this study were to investigate changes in the runoff regime and identify the driving forces associated with construction of the Yellow River Diversion Project. The results provide a reference for the water resource management that fully accounts for the benefits provided by water resources. A total of 33 hydrological indices and the overall runoff situation of the key section in the Yellow River Estuary, from 1958-2016, were analyzed using the index of hydrologic alteration/range of variability approach (IHA/RVA). The contribution of climate changes and human activities on the variation of runoff was quantified based on six Budyko hypothesis formulas. The study area was the Qucun section, the key section of the Yellow River Diversion Project, and data for calculating the hydrological indices were obtained from the Gaocun hydrologic station, about 7 km from the diversion inflow entrance. The study period (1958-2016) included two stages： TA (1958-2005), before project construction, and TB (2006-2016), after project construction. Annual runoff in the section decreased significantly from TA to TB. After 2006, the overall degree of variation of the runoff regime reached 61.72% and, using a degree of change above 67% as the threshold value, 8 hydrological indices changed substantially. The average contributions of climate change and human activities to variation in runoff were, respectively, 41.79% and 58.21%. Thus, human activities were the primary driving forces affecting runoff in the key section of the Yellow River Diversion Project. Human activities, such as a water conservancy project and soil conservation efforts were major drivers of changes in runoff, consistent with previous research results. To promote the development of water ecology benefits, effective regulation of water and sediment, hydropower and other human activities should be considered. |
