摘要:
文章通过对2019年黄河下游平原区地下水流场的刻画,结合黄河水和沿岸地下水的稳定同位素18O和放射性同位素3H的分布特征,分析了小浪底水库运行20年后黄河下游侧渗影响带的范围及变化。结果表明:小浪底水库运行20年后,现状黄河下游影响带在5~25 km,在新乡-开封一带最大,约25 km,在滨州一带最小,约5 km。相对于小浪底水库运行初期,影响带在滨州以西增加0.5~5 km,尤其在新乡-郑州沿线增大最为显著,而在滨州以东影响带略有缩小。黄河影响带主要由介质条件,补给源条件和能量条件等因素控制。小浪底水库运行后,河道下切,河床渗透性增强,降低了河床物质对黄河水的"吸附和净化"能力。黄河水的水质将对沿岸地下水产生更加明显的影响,控制和改善黄河水质是保障黄河下游区生态环境高质量发展的基础。

Abstract:
Based on the groundwater level measured in 2009 in the downstream of Yellow River plain, combined with the isotopic (18O and 3H)geochemistry of surface water and the groundwater, the lateral seepage scope and variation of downstream of Yellow River were analyzed after 20 years' operation of Xiaolangdi reservoir. The result indicates that in 20 years of operation of Xiaolangdi reservoir, the current scope of lateral seepage of the downstream of Yellow River will be between 5-25 km, with the largest scope of about 25 km in Xinxiang-Kaifeng and the smallest scope of 5 km in Binzhou. Compared with affected scope of lateral seepage in the initial operation of Xiaolangdi reservoir, the affected scope increased by about 0.5-5 km in the west of Binzhou, with most significant increment along Xinxiang-Zhengzhou, and slight decrement in the east of Binzhou. The affected scope of lateral seepage was mainly controlled by medium condition, recharge source condition and energy condition. After Xiaolangdi reservoir was put into operation, the channel was cut down, the permeability of the river bed was enhanced, and the "adsorption and purification" ability of the river bed material to the Yellow River water was reduced. Then, the water quality of Yellow River has a significant impact on the groundwater quality along the river. Hence, the control and improvement of water quality of Yellow River was the basis to ensure the high-quality development of the ecological environment in the basin of down-Yellow River.
