基于可拓融合的土壤重金属污染评价方法

A Novel Evaluation Approach to Soil Environment Quality Based on Extension Theory and Information Fusion

提出了用于土壤环境质量评价的可拓融合模型,探讨了可拓集在土壤环境质量评价中的应用。结果表明,该模型能够反映土壤环境的污染等级,实现了对土壤环境信息的定性与定量的集成描述。运用该方法对某地区土壤污染进行了等级评判,得出的结论符合实际情况,验证了该方法的有效性和可行性。

This paper proposed a novel evaluation model to soil environment quality based on extension theory and information.The application of extension set in soil polluted degree by heavy metal was discussed.The information of soil environment could be described by qualitative and quantitative manners.As an example,the proposed method was used to assess a concrete application.The results showed that the method was feasible and effective,and the evaluation results were more reasonable.
