寺沟铅锌矿区土壤重金属污染评价研究

Study on Soil Heavy Metals Pollution in Sigou Coal Mine Area

本文介绍了灰色关联分析法用于土壤环境质量评价的基本步骤。通过对陕西凤县寺沟铅锌矿区的土样进行测试,选取Pb、Zn、Cu、Cd、Cr等为评价因子,采用灰色关联分析法对土壤重金属污染状况进行评价。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较完整地反映土壤环境质量污染程度,是一种实用而准确的评价方法。

Introduced the basic steps of gray correlation analysis for soil environmental quality. Carry on the test to the soil sample in Sigou lead-zinc mine area at Feng country in Shaanxi province. The contents of heavy metals- Pb, Zn, Cu, Cd, and Cr in soil were studied to evaluate the soil environmental quality by using gray correlation analysis method with single factor deciding model. The result indicated that based on the Gray Correlation Analysis of heavy metal contamination of soil evaluation method can reflect completely of the quality of the environment pollution of soil, is a practical and the accurate method of evaluation.
