摘　　要：针对上饶市的地下水污染实例,运用DRASTIC模型对地下水水污染特征和迁移规律进行评估。研究结果表明:本研究区的地下水脆弱性属于中等水平,说明地下水具有一定的抗污染能力,不易受到自然表面入渗的影响。由于室内空气流通性较差,挥发有机污染物在被清理出地下水时,地下水饮用要加强管理,并且要减少室内空气吸入,降低人体健康受危害的风险。地下水的对流作用是推动二氯乙烷的迁移的主要因素。Given that groundwater pollution has posed a huge threat to human health and the ecological environment.This article evaluates the characteristics and migration patterns of groundwater pollution in Shangrao City using the DRASTIC model,and analyzes the pollution characteristics and distribution patterns.Due to poor indoor air circulation,when volatile organic pollutants are removed from groundwater,it is necessary to strengthen management of groundwater consumption and reduce indoor air intake to reduce the risk of harm to human health.The convection of groundwater is the main factor driving the migration of dichloroethane.
