摘　　要：为了探究上海市金山区典型工业区和非工业区土壤理化性质及重金属污染情况,选取具有代表性的城区绿地(N0)和工业区林地(N1)2处土壤进行采样,测定不同土层的土壤物理性质及表层土壤化学性质及重金属含量,并对表层土壤重金属的累积状况和污染来源进行分析与评价。结果显示,城区绿地和工业区林地土壤分别属中性土壤和酸性土壤。N1组表层土壤容重略低于N0组,表层其余各物理特性指标均略高于N0组表层土壤。2区土壤有机碳和全磷含量具有显著性差异(P<0.05)。此外,2区域表层土壤锌(Zn)、铅(Pb)及镍(Ni)元素含量均超过上海市土壤重金属背景值。研究表明,城区绿地和工业区林地土壤物理性能表现不佳,有机质及养分较匮乏,且已存在土壤重金属累积的状况,具有潜在的土壤生态污染风险。未来应及时采取有效措施加强污染监测与防控,并根据2区域土壤特性有针对性地进行改良和养护,进一步提高土壤综合质量。In order to investigate the physico-chemical properties and heavy metal content of soils in typical industrial and non-industrial areas in Jinshan District,Shanghai,two areas of urban green space(N0)and industrial forest land(N1)were selected for soil sampling.The physical properties of the soils in different soil layers as well as the chemical properties and heavy metal contents of the surface soils were measured,and the pollution sources of heavy metals in the surface soil was analyzed and evaluated.The results showed that the urban green space soil and the industrial forest land soil were neutral and acidic,respectively.For surface soil,the bulk density in N1 was slightly lower than that in N0,and the other physical property indexes were slightly higher than those in N0.The organic carbon and total phosphorus contents of the two areas were significantly different(P<0.05).In addition,the soil surface Zn,Pb and Ni contents of in the two areas exceeded Shanghai soil background values.In conclusion,urban and industrial areas soil had poor physical properties,organic matter and nutrients,and heavy metals accumulated led to potential ecological pollution risks in soil.In the future,effective measures should be taken in a timely manner to strengthen pollution monitoring,prevention and control,and to conserve the soil in Jinshan District according to the soil characteristics,so as to further improve the whole quality of the soil.
