灰色关联分析法在土壤重金属污染评价中的应用

Application of Gray Correlation Analysis to the Evaluation of Heavy Metal Pollution of Soil

以陕西凤县寺沟铅锌矿区土壤重金属污染评价为例,介绍了灰色关联分析法在土壤重金属污染评价中的应用,结果表明基于灰色关联分析的土壤重金属污染评价方法能够较完整地反映土壤重金属污染程度,是一种实用且准确的评价方法。

This paper introduces the basic steps of Gray Correlation Analysis for the evaluation of soil environmental quality, and taking Sigou lead-zinc mine area in Feng County in Shaanxi Province as the examle, discusses the Gray Correlation Analysis method in the evaluation of soil environmental quality. The result indicates that the soil evaluation of heavy metal contamination based on Gray Correlation Analysis can completely reflect the quality of the environment pollution of soil, and therefore it is a practical and the accurate method of evaluation.
