| 摘 要： | 地下水防污性能的评价,是确定地下水资源保护措施是否可行的关键.根据湛江市浅层地下水水文地质状况,在特定情况下对DRASTIC模型进行合理简化,选取包气带岩性、厚度与结构、地形作为评价因子,并利用GIS技术编制浅层地下水防污性能分区图.应用实测的地下水硝酸盐浓度分布状况对评价结果进行验证,结果表明:在特定条件下简化的DRASTIC评价方法能够较真实地反映湛江市浅层地下水防污性能.

| Abstract: | Assessment of groundwater vulnerability is the key issue to establish groundwater resources reservation strategy.According to particular conditions of Zhanjiang city's hydrogeological condition,DRASTIC model is simplified specifically and zone of aeration(thickness,lithology,structure) as well as topography is selected as assessment factors of shallow groundwater.Then the vulnerability distribution map is made with GIS tools.The result of assessment is verified by the field-measure nitrate concentrations of groundwater.It shows that simplified DRASTIC method is an efficient one to assess the shallow groundwater vulnerability in specific conditions. |
