摘  要：
以苏南小镇为依托,采用地累积指数法、污染负荷指数法和内梅罗指数结合土壤环境质量标准的改进法对研究区域土壤重金属污染进行评价,比较各种方法的适用性。结果表明,内梅罗指数结合土壤环境质量标准的改进法综合了人为因素和自然因素的作用情况,分析结果更为客观,且污染分布的区分度较高,兼有地累积指数法和污染负荷指数法的优点,更适用于小尺度地区的土壤重金属污染评价。

摘  要：
Taking a small town in southern areas of Jiangsu Province as an example,the soil heavy metal pollution in research area was evaluated by using geo-accumulation index method,pollution load index method and the modified method of Nemero index combined with soil environmental quality standards. The feasibility of these methods was discussed. The results showed that the modified method of Nemerow index combined with soil environmental quality standards combined with human factors and natural factors. This method had advantages of more objective evaluation results,higher discriminabiltity of pollution distribution. And the modified method of Nemerow index had the advantages of both geo-accumulation index method and pollution load index method,so this method was most suitable for the evaluation of soil heavy metal pollution in a small scale region.
