| 摘 要： | 选择污染严重的乐安江河流沉积物为对象，利用风险因子Ｅ和风险指数ＲＩ等定量诊断工具开展沉积物中重金属污染的潜在生态风险评价。根据风险指标体系和空间分异规律，将流域划分居不同特征的４种生态风险功能区。对比评价效果。潜在生态风险评价与地积累 情况大同小异，可以相互补充和借鉴。

| Abstract: | As the quantitative diagnostic tools,the toxic response factor ( E i r ) and the potential ecological risk index ( RI ) were used to evaluate the contamination situation of various heavy metals in sediments of the Le An River.As a result,the distribution of pollutants in the river sediments were divided into four sections with different ecological risk characteristics.On the whole,the assessing results by RI were consistent with that by I geo ,and they could complement each other. |
