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

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。

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

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 quality.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.
