| 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。 |
| 英文摘要: |
| 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. |
