摘要

分别采集了温州市区风景区、交通干线、住宅区、文教区、工业区土壤样品21个

郊区农田保护区土壤样品2个

测定了各土壤样品的基本理化性质和Cu

Cd含量。结果表明:各土样Cu

Pb的平均含量分别为(34.59±18.29)mg/kg

(169.40±52.97)mg/kg

(65.22±26.86)mg/kg

均超出温州土壤背景值。Cd仅在个别土样中检出

且浓度极低。各形态含量的分析结果表明

Pb均以残余态为主

分别为60.17%

50.95%

47.33%。Cu和Pb的酸提取态含量最低

Zn则是有机态含量最低。各形态含量与土壤基本理化性质的相关分析结果表明

Zn各形态与有机质含量的相关性最大

而Pb则与土壤基本理化性质之间无明显相关关系。
