| 摘 要： | 通过分析地下水环境脆弱性影响因素,以物元模型、可拓集合与关联函数理论为基础,建立了多指标多级的地下水环境脆弱性可拓综合评价的物元模型,通过计算其关联度,将多因子的评价归结为单目标决策,以定量的数值表示评定结果,从而能较完整地反映地下水环境的脆弱性.宁陵县的应用表明,多指标多级可拓评价模型在地下水环境脆弱性评价中具有较好的应用效果. |

| Abstract: | After analyzing the factors of the groundwater environmental vulnerability, the paper establishes multi--factorial multilevel extension evaluation model based on matter element, extension sets and correlation function to asseas the groundwater environmental vulnerability. Through calculation of the correlation degree, multi-factorial evaluation is transformed into the single-object decision, therefore, the groundwater environmental vulnerability can be effectively reflected. The application in Ningling county shows its good practical expectation. |
