四川省内江市双桥乡土壤重金属污染及生态风险性评价

On Heavy Metal Pollution and Ecological Risk Assessment in Surficial Soil of Shuangqiao Rural of Neijiang City in Sichuan Province

利用内梅罗指数和潜在生态风险指数法对四川省内江市双桥乡土壤环境质量进行评价,并结合GIS空间技术分析各重金属元素及综合污染等级分布。结果表明,该区主要为内梅罗污染指数评价轻度污染区域和潜在生态评价轻度危害区域。

Soil environmental quality of Shuangqiao rural of Neijiang City was assessed by Nemerow index and potential ecological risk index, and each heavy metal element and its grade distribution of integrated pollution was analyzed based on GIS technology. This area was the slight pollution area based on Nemerow index and the slight danger area based on ecological risk assessment.
