基于DRASTIC模型的地下水脆弱性评价方法评述

摘要

The evaluation method for groundwater vulnerability was analyzed based on DRASTIC, the limitations and defects of the model was discussed, application effect of the modified model was evaluated. The application prospect of the evaluation method based on DRASTIC model was analyzed, the key issue about the selection and application of the model was proposed and the evaluation results should be transferred into value maximization.%首先分析了基于DRASTIC模型的地下水脆弱性评价方法,然后探讨了该模型的局限性和缺陷,并评述了改进模型的应用效果,最后对基于DRASTIC模型评价方法的应用前景进行了分析,提出了关于选用和应用该模型需要重点关注的问题和评价成果需实现成果价值最大化.
