基于改进模糊综合评价法的地质异常区土壤重金属污染评价--以江苏灌南县为例
Evaluation of soil heavy metal pollution of geological anomaly area based on improved fuzzy comprehensive evaluation method---A case study of Guannan in Jiangsu Province, China
摘要
Abstract
In this paper, the agricultural production area of Guannan County in Jiangsu Province was taken as the research area. Analytic hi-erarchy process and entropy law method were used to improve the traditional fuzzy comprehensive evaluation method. The improved method was applied to the comprehensive evaluation of heavy metals in soil of this region. Results showed that there was no serious pollution in the collected 30 samples and the pollution level of these samples was between Class I and ClassII. There had nine sample points at the levelIIand the other sampling points were closed to level I. Results of comprehensive evaluation values of each sample fluctuated significantly. Observing and analyzing the position distribution of these nine samples indicated that these samples were distributed in the vicinity of both sides of the highway. Comparative analysis found that the Cd content of these nine samples was higher than other samples with a possible contribution from traffic based human activities which made the exogenous heavy metals into the soil. Anthropogenic sources such as traffic further increased concentrations of heavy metals in this geological anomaly area as indicated by pollution assessment in this study.关键词
