Groundwater vulnerability analysis addressesthe degree of sensitivity of groundwater system to-wards the changes in both intrinsic/inherent and ex-trinsic factors.In this work,an integrated AHP-GISbased modified DRASTIC method was followed toconduct the impact of various hydrogeological indi-cators towards groundwater vulnerability in Nan-chang city.The results show that the DRASTIC-LUmodel could accurately identify the vulnerability ofgroundwater with prediction efficiency about 70.3%,and more than 20% of groundwater has a high pollu-tion potential due to shallow groundwater table,highhydraulic conductivity and agricultural irrigation.
