摘要：对徐州丰县六个村庄的牛蒡和土壤中重金属进行测定，基于统计和分析软件spss19.0，通过变量分析对牛蒡和环境土壤中重金属相关性分析。以期为牛蒡的栽培和生产提供理论依据。利用石墨炉原子吸收法测定六个不同地区的牛蒡和土壤中镉、汞、铬、铜、锰、铅的含量；用尼梅罗污染指数法评价土壤质量。土壤中镉、汞、铬、铜、锰、铅含量和牛蒡中镉、汞、铬、铜、锰、铅含量呈正相关关系，相关系数分别是镉：0.926；汞：0.957；铬：0.987；铜：0.953；锰：0.980；铅：0.990。

Abstract：This text determines the heavy metal in the burdocks and soil of six villages in Feng County of Xuzhou, because of counting and analyzing the software spss19.0, analyze to the heavy metal relevance analysis in the burdock and environmental soil through the variable. In the hope of providing the theoretical foundation for culture and production of the burdock.Utilize graphite stove atom to absorb cadmium, mercury, chromium, copper, manganese, plumbous content in burdock and soil that the law determines six different areas; Appraise soil quality with Buddhist nun plum pollution index law Luo.Cadmium, mercury, chromium, copper, manganese, lead content present the positive correlation relation in cadmium, mercury, chromium, copper, manganese, lead content and burdock in the soil, the coefficient correlation is cadmium separately: 0.926; Mercury: 0.957; Chromium: 0.987; Copper: 0.953; Manganese: 0.980; Lead: 0.990.
Keywords Burdock Heavy metal Soil Relevance analysis
