通过田间采样和室内分析,对不同种植作物土壤中的Cr、Cu、As、Pb、Zn含量及污染状况进行分析研究,结果表明,全部土壤样品中As的含量低于陕西和全国的平均值,低于半数土样中Cr的含量高于陕西或全国平均值,超过半数以上的土样中Cu、Zn的含量高于陕西或全国平均值,所有土样中Pb含量高于陕西或全国平均值.单因子污染指数法和综合污染指数法的研究分析表明,以国家二级标准为评价标准,研究区土壤未受污染,土壤为清洁,土壤质量完全符合农作物生长条件.

Through sampling in farmland and analysis in laboratory, the contents and the pollution level of Cr, Cu, As, Pb, Zn in different soils were studied. The comparative result showed that the As in all soil samples are lower than the mean value of Shaanxi and whole nation, the Cr in lower half soil samples are higher than the mean value of Shaanxi and whole nation, the Cu and Zn in majority soil samples are higher than the mean value of Shaanxi and whole nation, and the Pb in all soil samples is higher than the mean value of Shaanxi and whole nation. The single factor pollution index and multi-factor pollution index method were used to evaluate the soil pollution. According to Soil Environmental Quality Standard, the studied soils were at unpolluted degrees, the soils were clear, the quality of soil adapt to the crop growth, and not affect the quality of agricultural product.
