排土场淋溶水对地下水质影响的灰色聚类分析

Grey-clustering analysis of quality of underground water contaminated by leaching water in waste disposal area

就阜新新邱露天煤矿排土场淋溶水对附近于家沟地区地下水环境质量的影响进行了研究。首先,对研究区内的17眼水井分别采样,进行水质分析,识别出主要污染因子;进而,采用灰色聚类分析方法对影响区内每个监测点的水质进行了评价,确定出地下水环境质量等级,并将评价结果与模糊综合评价和灰色关联分析等方法相比较,为污染区地下水质的区划提供了可靠的依据。

The underground water in the area of Yujiagou has been contaminated by the leaching water of the dumping area of open pit coal mine of Xinqiu in Fuxin. To determine the pollution limits of underground water, the author took samples from 17 water wells in the studied area, analyzed samples for water quality, recognized the main pollution factors, assessed the water quality of each water well, making use of grey -clustering analysis method, gave out the classifications of the underground water quality of the study area. Comparing with grey associated analysis method and fuzzy comprehensive appraisal method, it is demonstrated that the results of the water quality appraisals gained by three methods are identical basically.
