摘  要：
为给煤矸山复垦区的生态重建提供依据,以山西省霍州市曹村煤矿复垦6年的煤矸山为例,分析农田、蔬菜地、果园和荒草地等4种利用类型复垦地土壤重金属元素Pb、Zn、Cr、Cu含量的差异;同时运用单因子污染指数和内梅罗综合污染指数法,对4种样地土壤重金属污染状况进行生态风险评价。结果表明:Cu在4种样地中的含量均超过山西省土壤背景值;Pb在蔬菜地未超标,在农田、果园和荒草地分别超标15.7%、18.9%、20.2%;Cr在果园未超标,在农田、蔬菜地和荒草地分别超标12.6%、6.9%、87.4%,而Zn在4种样地中均未超标。从单项污染指数评价看,Cu和Pb除在蔬菜地分别为轻度累积和未累积外,在其他3种样地中均分别为中度累积和轻度累积;Cr除在果园未累积外,在其他3种样地均达轻度累积,Zn在4种样地均未累积。从综合污染指数看,4种样地重金属均出现不同程度的累积,其中荒草地和果园达到中度累积,玉米地和蔬菜地达轻度累积。

摘  要：
In order to effectively guide the ecological reconstruction of coal mine area,taking the coal waste pile reclaimed for six years in Cao village,Huozhou Country,Shanxi Province as an example,the authors analyzed the contents of heavy metals(Cu,Pb,Cr,Zn)in the reconstructed soil of four kinds of soil samples,including farmland,vegetable land,orchard and weeds land.The ecological risk of heavy metal pollution in the four kinds of soil samples was evaluated by adopting the single factor index and Nemerow integrated index.Results:Content of Cu in four kinds of soil samples exceeded the soil background values in Shanxi Province,the content of Pb in vegetable land did not exceed the standard,but the over standard rate of farmland,orchard and weeds land were respectively 15.7%,18.9%and 20.2%;The content of Cr in orchard did not exceed the standard,but the over standard rate of farmland,vegetable land and weeds land were respectively 12.6%,6.9% and 87.4%.The content of Zn in the four kinds of soil samples did not exceed the soil background values in Shanxi Province.From the point of single pollution index evaluation results,Cu and Pb in vegetable land reached respectively light accumulation and no accumulation,in the other three soil samples reached respectively moderate accumulation and light accumulation,Cr in orchard reached no accumulation,in the other three soil samples reached light accumulation,Zn in the four kinds of soil samples was no accumulation.From the point of comprehensive pollution index evaluation results,four types of soil samples accumulated in different degrees,orchard and weeds land reached moderate accumulation,farmland and vegetable land reached light accumulation.
