摘　　要：采用基于DRASTIC方法改进后的DRMSI模型,对六安市丰乐河-杭埠河河间平原地区进行了地下水防污性能评价,根据研究目的结合自然地理、土壤、水文地质等特征,通过合理选择评价因子重组评价指标,改善了地下水防污性能评价模型,并对评价结果及评价方法进行了验证。结果显示研究区地下防污性能等级和地下水质量等级的分区区域基本吻合,进一步表明DRMSI模型评价方法适宜于小流域河间平原地下水防污性能的评价。本研究对在小流域河间平原区开展地下水防污性能的评价具有示范意义。The DRMSI model improved based on DRASTIC method is used to evaluate the anti-pollution performance of groundwater in the plain area between Fengle River and Hangbu River in Lu ’an City. According to objectives of the research and the characteristics of physical geography, soil and hydrogeology, the evaluation factors are reasonably reselected and reorganized for improving the evaluation model of anti-pollution performance of groundwater. The evaluation results and evaluation methods are verified. The results show that the level of underground anti-pollution performance in the study area is basically consistent with the level of groundwater quality, which further indicates that the DRMSI evaluation model is suitable for the evaluation of groundwater anti-pollution performance in a small watershed plain between rivers. It is of exemplary significance for evaluation of anti-pollution performance of groundwater in a small watershed plain between rivers.
