为了解南昌市县区蔬菜种植区土壤中重金属污染程度,在新建县、安义县和南昌县各选1个蔬菜种植基地作为采样地,共采集15个样品,测定了土壤中10种重金属元素含量,并用单因子污染指数法、综合污染指数法和潜在生态风险指数法对污染状况进行评价。单项污染指数表明除新建县基地受到Ni轻微污染物,各基地的金属元素含量均是达标的；综合污染指数法表明南昌县和新建县的污染等级为尚清洁,安义县的污染等级为清洁；潜在生态风险指数法表明新建县处于轻微生态危害水平,安义县和南昌县处于中等生态危害水平,3个蔬菜基地中, Hg和Cd均为土壤中重金属的主要生态危害因子。

To further understand the pollution degree of heavy metal in soil at vegetable bases in counties of Nanchang city, taking three vegetable bases as the sampling places ( Xinjian county, Nanchang county and Anyi county one each) , 15 samples were collected. The content of ten heavy metal elements in soil were determined, the pollution status was evaluated with the single factor index method, nemerow multi-factor index method and Hakanson potential ecological risk index method, respectively. The single factor index indicated that the soil was just slighdy polluted by nickel in Xinjian county and there was no other heavy medal pollution in other counties. Judged by the nemerow index, Xinjian county and Nanchang county were in the alert level while Anyi county was in the safety leve 1. The potential ecological risk of Anyi county and Nanchang county were medium, and Xianjian county was slight. Cd and Hg were the major pollution elements in three counties.
