摘要
通过对南宁市郊 1 2个主要菜区土壤中重金属 ( Cu、Zn、Cd、Pb)含量的调查和分析测定 ,采用模糊综合评判方法对土壤重金属污染状况进行评价。结果表明 :南宁市郊部分蔬菜区土壤不同程度地受到Cu、 Zn、 Pb、 Cd的污染 ,污染程度依次是 :Cd>Pb>Zn>Cu。 1 2个样点污染程度依次为 n2 =n6 =n1 1 >n7=n8=n9>n1 =n4 >n5>n1 2 >n3=n1
Based on the analyses of heavy metal elements(Cu、Zn、Pb、 Cd) content in soils from twelve main planting vegetable areas in Nanning,it was evaluated the degree of heavy metal pollution in soil with fuzzy comprehensive assessment. The results showed that most of soils have been differently polluted by heavy metal elements such as copper, zinc, lead , and cadmium . The degree of pollution showed order as follow: Cd>Pb>Zn>Cu.The degree of pollution of the 12 samples showed order as follow: n 2=n 6=n 11 >n 7=n 8=n 9>n 1=n 4>n 5>n 12 >n 3=n 10 .
