摘　　要：利用AHP及ArcGIS技术对原有DRASTIC模型进行改进,并以辽源市地下水状况为例对地下水脆弱性进行研究,得到了辽源市地下水脆弱性评价结果。结果表明:地下水脆弱性总体呈低脆弱性水平,占60.33%;西北部和东南部脆弱性中等,占17.97%;西部地区及水源地周边脆弱性较高,占21.70%,易遭受污染。改进后的DRASTIC模型更能体现研究区现状,可为辽源市地下水污染防治提供科学依据。AHP and ArcGIS techniques were used to improve the original DRASTIC model,and groundwater vulnerability was studied by taking Liaoyuan City as an example,and the assessment results of groundwater vulnerability in Liaoyuan City were obtained.The results showed that:the overall vulnerability of groundwater was low,accounting for 60.33%;the northwest and southeast were moderately vulnerable,accounting for 17.97%;the vulnerability of the western region and the surrounding areas of the water source was high,accounting for 21.70%,which was susceptible to pollution.The improved DRASTIC model could better reflect the current situation of the study area,and could provide scientific basis and reference for groundwater pollution prevention and control in Liaoyuan City.
