| 中文摘要: |
| 本文指出了国外广泛采用的含水层本质脆弱性评价DRASTIC方法的缺点。建立了含水层污染性难易程度评价的模糊分析理论与模型，给出了10个级别7项DRASTIC指标的指标标准特征值和对含水层污染难易程度进行评价的10级语气算子，提出了确定含水层脆弱性评价指标权重的方法——语气算子比较法。从而形成了比较完整的含水层本质脆弱性模糊分析评价的理论、模型与方法。 |
| 英文摘要: |
| Based on the analysis of weakness of the DRASTIC index,which is popularly used abroad,a fuzzy analyses theory and corresponding model for evaluating aquifer vulnerability are established.For each factor in the DRASTIC index 10 classes of standard values are given.Correspondingly,the aquifer vulnerability is divided into to 10 levels,which are respectively related to a linguistic variable.Pair wise comparison approach is used to assess the weights of 7 factors.Thereby,an integrated evaluation framework and methodology for aquifer vulnerability is formed. |
