| 权重的确定在地下水水质评价中具有重要作用。利用CRITIC方法对地下水指标进行权重修正,探究该方法对地下水质量评价的适用性。笔者选取代表性指标后,按照一般化学指标、毒理学指标2个层次构建地下水污染评价综合指标体系,建立基于AHP-CRITIC综合权重的改进物元可拓模型对研究区地下水开展质量评价。将开发的评价方法应用于工业园区地下水质量评价发现,该方法能够反映地下水质量状况。结果表明:该评价方法在地下水质量评价过程中,能够兼顾不同指标重要程度差异和水质等级的模糊性,研究区5#点位和10#点位有毒有害重金属超标,应进一步查明原因,提出地下水污染阻断措施。 |

| The determination of weight plays an important role in the evaluation of groundwater quality. This paper uses CRITIC method to modify the weight of groundwater indicators and explore the applicability of this method to the evaluation of groundwater quality. After selecting representative indicators,the author constructs a comprehensive indicator system for groundwater pollution assessment based on general chemical indicators and toxicological indicators, and establishes an improved matter-element extension model based on AHP-CRITIC comprehensive weight to evaluate groundwater quality in the study area,and compares it with the single indicator assessment method. Applying the developed evaluation method to the evaluation of groundwater quality in industrial parks,it is found that this method can reflect the quality status of groundwater. The results show that the evaluation method proposed by the author can take into account the difference in the importance of different indicators and the fuzziness of water quality grade in the process of groundwater quality evaluation. The toxic and harmful heavy metals at 5 # and 10 # sites in the park exceed the standard. Further work should be carried out to find out the causes and propose measures to block groundwater pollution. |
