| 中文摘要: |
| 利用集对分析的原创联系度可展性，对其进行改进，将其推广到五级评判，进而建立了地下水环境评价模型。结合模糊综合评判方法，针对地下水环境的7项主要影响因子进行评价，可得到各地下水测点的评价结果，以及处于各评价等级的趋同程度。应用该方法进行实例计算，并与综合指数法、灰色关联法计算结果进行比较，结果表明：本方法评判效果较好，能够真实反映研究对象的状况，具有很好的工程应用价值。 |
| 英文摘要: |
| An improved set pair analysis (SPA) method utilizing the malleability of the original relation degree to extend the evaluation ranking of groundwater environment to 5 levels is suggested. The method can be used to combine with fuzzy method for obtaining the comprehensive evaluation result of groundwater samples as well as their tendency degree to the corresponding ranking based on 7 main factors of groundwater environment. The application result of the proposed method to an example is compare with the results of synthesis index method and gray associate analysis method. It shows that the proposed improved set pair analysis is feasible and reliable. |
