为了解南京市江宁区土壤中重金属污染现状,本实验对南京市江宁区土壤重金属污染现状进行了调查评价,并对其潜在生态危害进行了评价。结果表明,土壤重金属污染程度依次为Pb>Cu>Zn;以土壤背景值为评价标准时,平均内梅罗综合指数3.22,土壤污染严重。而潜在生态风险指数<27.0。土壤重金属Pb、 Cu、 Zn轻微污染;以国家二级土壤标准为评价标准时,平均内梅罗综合指数0.30,土壤清洁。而潜在生态风险指数<10.0,土壤重金属轻微污染。
為瞭解南京市江寧區土壤中重金屬汙染現狀,本實驗對南京市江寧區土壤重金屬汙染現狀進行瞭調查評價,併對其潛在生態危害進行瞭評價。結果錶明,土壤重金屬汙染程度依次為Pb>Cu>Zn;以土壤揹景值為評價標準時,平均內梅囉綜閤指數3.22,土壤汙染嚴重。而潛在生態風險指數<27.0。土壤重金屬Pb、 Cu、 Zn輕微汙染;以國傢二級土壤標準為評價標準時,平均內梅囉綜閤指數0.30,土壤清潔。而潛在生態風險指數<10.0,土壤重金屬輕微汙染。

To understand soil heavy metals pollution in Jiangning District of Nanjing City, the concentrations of heavy metals in the surface soil of the Jiangning district were investigated, and their potential ecological hazards were evaluated. The results showed that heavy metals pollution ranked as Pb>Cu>Zn. With the background value of the soil as evaluation standard, the average nemerow index was 3. 22 which meant soil heavy pollution. But the potential ecological risk index<27. 0 that showed soil heavy metals mild pollution. With national standards value as assessment standard, the average nemerow index was 0. 30 which showed soil clean. But the potential ecological risk index <10. 0 , which meant soil heavy metal light pollution.
