摘　　要：以黑河市郊区农田表层土壤（0～20 cm）为研究对象,研究了土壤中6种重金属元素（Hg、As、Cd、Cr、Cu、Pb）的含量情况及可能来源,并对土壤中重金属污染状况进行了总体评价.结果表明,重金属在土壤中已有一定程度的累积,在地表的累积程度比较高,Hg的污染最为严重,已达到了警戒水平,但总体来说黑河市郊区土壤处于清洁水平,满足绿色食品和蔬菜生产的要求.The content of rig, As, Cd, Cr, Cu and Pb in different functional zones is studied, the relationship between heavy metals and different soil use and sampling depth is analyzed. The results indicated that the soil was contaminated by heavy metals, especially in the surface soil zones. The content of Hg is high and should be paid more attention. The soil is at clean level on the whole, so the soil meets the needs of producing green food and vegetables.
