摘要
文章以陕西省神木县西沟乡六道沟流域作为研究区域,对六道沟煤矿周围的土壤中锌的含量进行了研究,着重分析了煤矿开采是否对周围土壤造成重金属污染以及重金属锌在煤矿周围土壤中的分布特征。结果表明该区域仅有部分土壤遭受锌的轻度污染,即煤矿开采会对周围土壤造成不同程度的污染,且锌的含量随着距煤矿距离的增大而递减,并随采样深度增加而递减。
The article to Xigou village the sixth ditch in Shanxi province Shenmu county as investigation area. It has been studied the zinc content of the soil around the sixth ditch coal mine. Analysis focused on whether the surrounding soil in coal mining of heaving metal pol- lution, and heavy metals of zinc in mine distribution characteristics of surrounding soil. The results show that only part of the region affected by zinc in the soil was the light pollution, that the soil around the coal mining would result in different levels of pollution, and content of zinc as the distance increases from the reduced, and sampling depth increase with decreasing.
