基于灰色聚类的物元可拓法在地下水水质评价中的应用——以洮南市为例

Application of Matter-element Extension Method Based on Grey Clustering Theory in the Groundwater Quality Evaluation——Give an Example of Taonan City

灰色聚类分析法和物元可拓法都是进行水质评价时常用的方法。以吉林省洮南市为例,在灰色聚类法计算权重的基础上,运用物元可拓法对研究区的水环境质量状况进行评价和分析。研究结果表明,改进后的基于灰色聚类的物元可拓法模型具有较好的评价结果,与当地实际水环境质量状况更为一致,对研究区地下水的开采规划具有指导意义,为以后的水质评价提供借鉴。

The gray-clustering analysis method and the matter-element extension method are often used for water quality evaluation. Giving an example of Taonan City, on the basis of the gray clustering method to calculate weight, the matter-element extension method is used to assess and analyze the groundwater quality of the study area. The result proves that the improved matter-element extension method based on grey clustering theory has good evaluation results, and is consistent to the filed water environmental qual- ity. This method has guiding significance for the plan of groundwater exploitation in the study area, and it can provide reference for the future water quality assessment.
