该文以河南省贾鲁河中牟段为研究区，探究贾鲁河与河岸带浅层地下水的补排关系以及河水对浅层地下水的影响。通 过野外地质调查、水文地质试验、水位监测及水质检测，分析河岸带地表水与地下水的补排关系及污染特征。结果表明，受 中牟县抽取地下水的影响，该河段周围浅层地下水位低于河水位，河流补给地下水，平均单宽补给量为2.04 m2·d-1；河水中 NH3和COD污染较为严重，地下水中“三氮”均超标，其中NO2和NH3污染严重；河水NH3-N浓度远高于地下水，接受河 流补给的地下水NH3污染严重；因硝化作用，远离河流地下水NH3-N浓度逐渐降低，而NO3-N浓度逐渐升高。

In this study, field geological investigations, hydrogeological tests, water level monitoring, and water quality analyses were conducted to investigate the recharge and discharge between the seriously polluted Jialu River and the nearby groundwater in Henan province. The results indicate that the river stage was higher than the groundwater level because of nearby groundwater pumping, causing the river to recharge groundwater with an average water flux per unit width of 2.04 m2·d-1. The NH3 and COD pollution in the river was serious and the concentrations of NH3-N, NO2-N, and NO3-N in groundwater were all higher than the standards. The NO2 and NH3 pollution was especially serious; the NH3-N concentration in the river was much higher than that in groundwater and the NH3 pollution in groundwater near the river was more serious as a result of the river recharge, but was gradually reduced away from the river due to nitrification and adsorption. The NO3-N concentration in the river was lower than that in the groundwater and the NO3-N concentration in the groundwater gradually increases away from the river due to nitrification and infiltration of the nitrogen fertilizer applied at the land-surface.
