摘要：通过对秦淮河江宁段水岸带5种重金属元素:铜(Cu) 、锌( Zn) 、铬(Cr) 、镉(Cd) 、铅( Pb) 的含量分析，并运用地累积指数法对其污染程度进行评价，变异系数法对重金属沿程分布进行评价，用潜在生态危害指数法对重金属的潜在生态风险进行评价，对秦淮河江宁段水岸带典型区域土壤重金属污染现状进行了分析与评价。结果表明，各种重金属的污染程度依次为: Zn>Cd>Cu,重金属Cu 、Zn、 Cd都为中程度污染，Cr、 Pb均为无-中程度污染。上元大街、胜太东路和前河的重金属含量相对较高，而河定桥、秦淮河大桥、诚信大道的重金属含量相对较低。总体上，秦淮河水岸带重金属污染表现为轻微生态危害程度。

Abstract : By the Qinhuai Jiangning segment waterfront with five kinds of heavy metal elements: copper (Cu), zinc (Zn), chromium (Cr), cadmium (Cd), lead (Pb) content analysis, and the use of the accumulation index method on pollution levels, coefficient of variation method to evaluate the heavy metal distribution along the process to evaluate the potential ecological risk index of the potential ecological risk of heavy metals with a typical area of soil heavy metal pollution analysis and evaluation, the Qinhuai Jiangning segment waterfront. The results show that the heavy-metal pollution degree of the order: Zn> Cd> Cu, heavy metals of Cu, Zn and Cd in the degree of pollution, of Cr and Pb are from no to the degree of pollution. Shangyuan Street ,Shengtai East Road and heavy metal content of the Qian River is relatively high Heding Bridge, Qinhuai River Bridge, the integrity of the heavy metal content of the avenue is relatively low. Overall performance of heavy metal pollution in waterfront of qinhuai River is minor ecological damage.
Key words: waterfront; heavy metals; cumulative index; coefficient; method of potential ecological risk index
