摘要
通过水文地质调查和地下水监测孔观测资料,运用DRASTIC模型与GIS软件的区叠加功能,对研究区地下水脆弱性作评价,以及对地下水防污性能进行分区。结果表明:地下水防污性能较高区主要分布在西北部台地区及其附近,防污性能中等区主要分布于二级阶地,防污性能较低区主要沿河流及其分支河道的漫滩、一级阶地等地带呈条带状分布。总体来看,该区域地下水防污性能较好。
According to the data from hydrogeological survey and monitoring wells,the groundwater vulnerability in the study area was assessed by DRASTIC-GIS model superimposed with GIS software,and was zoned.Results showed that the groundwater vulnerability was high in and around the northwest platform.Moderate vulnerability zone was in second terrace.Low vulnerability zone appeared a banding distribution in first terrace and in the floodplain along rivers and their branches.As a whole,the groundwater vulnerability was good in the study area.
