摘　　要：地下水补给资源量评价是干旱地区地下水资源评价的最重要部分,但许多地区因为缺乏地下水的源汇项监测数据、或者水文地质研究程度较低,导致地下水补给资源量评价的可靠性较低。以柴达木盆地那陵郭勒河冲洪积扇区为例,采用地下水位波动方法(water-table fluctuation,WTF)对地下水补给资源量进行计算,该方法仅需要一段时间内含水层参数及地下水位变化值,应用简单,适用性强。通过计算表明,那陵郭勒冲洪积扇地区地下水资源2011年补给量约为5.21×108m3/年,2012年补给量约为6.16×108m3/年。该方法避免了直接计算地下水补给量的难题,对水文地质研究程度较低的干旱区地下水资源评价具有一定的参考意义和推广价值。Evaluation of groundwater recharge is one of the most important parts of the groundwater resources assessment in arid regions, the reliability of the groundwater resources assessment is low at many areas because of lacking of groundwater monitoring data or low degree of hydrogeological survey. Based on the groundwater level of long-term monitoring wells, the groundwater recharge quantity in Nalingguole River area was evaluated by using water-table fluctuation method, which just only needs aquifer parameters and groundwater level change values over a period of time. According to the results, the amount of groundwater recharge resources is 5.21×10^8m^3/a in 2011 and 6.16×10^8m^3/a in 2012 at study area. This method is relatively simple and avoids the direct calculation problem of groundwater resources items. It has certain reference significance at low study of hydrogeology of groundwater resources assessment in arid regions.
