摘　　要：为研究重金属元素在城市土壤中的空间分布特征,对上海市的城区、城郊结合部、郊区以及道路两侧分别进行布点采样。结果表明:所测区域Pb、Zn这2种元素在土壤中的含量与土壤距离道路的距离存在明显的负相关关系,同时其污染程度从市区到郊区存在明显的梯度关系。通过单因子污染指数和内梅罗综合污染指数进行评价,上海师范大学徐汇校区桂林路断面土壤为中度污染,闵行体育公园、莘庄公园、上海师范大学奉贤校区和A20道路两侧道路为轻度污染。To investigate the distribution characteristics of heavy metal elements in urban soil,samples were collected in Shanghai downtown,suburb,rural area and road side.The results showed that traffic-caused heavy metal elements Pb and Zn in soil had a negative relativity with the local area’s distance to the road.And there was a obrious gradient of pollution degree from urban to suburb.The pollution status of those sampling point was evaluated by single and Nemero contamination index.The evaluation illuminated the condition of heavy metal contaminants levels in different areas：the soil of road side in Shanghai Normal University was middle medium-level polluted,while the other areas were low-level polluted.
