摘要
采用模糊数学模型对合肥市南郊农业土壤中重金属元素(镉、汞、砷、铜、铅、锌)进行了综合污染评价,结果表明,评价区域土壤环境中的六种重金属元素均在标准之内,土壤环境质量为一级,属于安全、清洁级水平,符合无公害农产品基地的环境要求。
Based on fuzzy mathematic model, the pollution of heavy metals （ Cd, Hg, As, Cu, Pb, Zn） in soil in southern suburb of Hefei are evaluated. The results indicate that the content of the six heavy metals in the soil environment are all within the national standards. The soil environmental quality is Grade one which can satisfy the safety requirements and the field can be a base to produce harmless agricultural products.
