摘　　要：地下水作为肇州县唯一水资源,是生产、生活、灌溉等方面用水主要来源。为了合理规划地下水的开发利用,采用层次分析法(AHP)和DRASTIC模型相结合,根据研究区实际情况选取7个不同的评价指标构建DRASTL-CRD模型。利用ARCGIS空间分析功能对研究区地下水脆弱性进行分区,得到肇州县地下水脆弱性评价结果。结果表明:肇州县地下水脆弱性以中等脆弱性区为主,面积为750.23 km^(2),占总面积32.36%;肇州县南部地下水脆弱性高于北部。可为肇州县地下水污染防治提供科学依据。Groundwater is the main source of water for production,living and irrigation,as the only water resource in Zhaozhou County.In order to rationally plan the development and utilization of groundwater,the combination of analysis hierarcby process(AHP)and DRASTIC model is adopted and 7 different evaluation indexes are selected according to the actual situation of the study area to build DRASTL-CRD model.The groundwater vulnerability evaluation results of Zhaozhou County were obtained by using ARCGIS spatial analysis function to partition the groundwater vulnerability in the study area.The results show that the groundwater vulnerability in Zhaozhou County is mainly in the middle vulnerability area,with an area of 750.23 km^(2) accounting for 32.36%of the total area;The vulnerability of groundwater in the south of Zhaozhou county is higher than that in the north.This study can provide scientific basis for the prevention and control of groundwater pollution in Zhaozhou County and provide reference value for other areas of Songnen Plain and Songhua River Basin.
