| 摘 要： | 为提高地下水与地表水交换量计算结果的准确性，本文利用水力联系、水头差、水温、氡-222、氢氧稳定同位素构建综合识别方法（HHTRO），对新汴河宿州段地下水与地表水水量交换进行识别，并计算交换量。计算结果表明:研究河段单位河长地表水补给地下水的水量变化范围为8.69~366.82 m3/（d·m），地下水补给地表水的水量变化范围为0.72~120.90 m3/（d·m）；研究河段左岸为地下水补给地表水，单位河长净补给量为45.26 m3/（d·m）；河段右岸为地表水补给地下水，单位河长净补给量为214.33 m3/（d·m）；研究河段地下水与地表水水量交换以地表水补给地下水为主，地表水补给地下水的比例为55.14%。本研究可推动地下水与地表水交换量计算方法的发展，为流域或区域水资源评价提供必要的理论方法。

| Abstract: | In order to improve the calculation accuracy of flow exchange between groundwater and surface water,a method that integrates the hydraulic connection and hydraulic head difference between groundwater and surface water,water temperature,Radon-222 and stable hydrogen and oxygen isotopes(HHTRO)was proposed and successfully applied to quantify the flow exchanges between groundwater and surface water in the Suzhou section of the Xinbian River.The study results showed the recharge from surface water to groundwater varied from 8.69 to 366.82 m3/(d·m)per unit river length and the discharge from groundwater to surface water varied from 0.72 to 120.90 m3/(d·m).The discharge from groundwater to surface water was predominantly on the left bank with a net discharge of around 45.26 m3/(d·m)and the recharge from stream to groundwater was mostly on the right bank with a net recharge of approximately 214.33 m3/(d·m).Overall,the flow exchange between surface water and groundwater in this river section was dominated by the recharge from surface water to groundwater with a replenishing ratio of 55.14%for groundwater.This method would not only improve the accuracy for estimating the flow exchange between groundwater and surface water provide necessary theoretical support for water resources development in river basins. |
