摘要
阜新海州露天煤矿已经关闭破产,排土场的存在不仅占用大量土地,而且给周围居民的生产和生活带来很大不便,需要对其进行植被恢复。为了了解该区域的土壤重金属情况,对排土场进行土壤采样,并进行样品分析,采用灰色关联分析法对每个监测点的土壤进行评价,确定土壤质量级别。结果表明,灰色关联分析方法能够较好的进行土壤环境质量评价,计算方便,操作性强,易于推广。
The Haizhou surface mine in Fuxin has been closed bankruptcy,the existence of the surface mine dump is not only took up a lot of lands but also brought up a great of inconvenience to the product and daily life of surrounding residents, so it needs to be the restored, In order to understanding of the heavy metals in soils in the region, it needed the soil samples, and sample＇s analysis, and used gray correlation analysis for each monitoring point to evaluate the soil to determine soft quality level; the result shows that the grey correlation analysis method can better evaluates the environmental quality of soils, It＇s a convenient and operational, And it is easy to spreaded.
