基于集对分析与三角模糊数耦合的土壤重金属污染评价模型
A Coupling Model of Set Pair Analysis and Triangular Fuzzy Numbers for Evaluation of Soil Heavy Metal Pollution
摘要
Abstract
The comprehensive evaluation on pollution degree of soil heavy metals is a hot issue and complicated uncertain problem.Here a novel model coupling the theory of set pair analysis and the triangular fuzzy numbers was discussed to assess the pollution of soil heavy metal.The certain and uncertain characteristics in the evaluation procedure were described by using set pair analysis method.In order to improve the method of set pair analysis, the triangular fuzzy numbers were introduced to describe the discrepancy degree coefficient of set pair.practical example was used to test the reliability and the validity of presented analysis model, and it was found that compared with the other methods, this proposed model was more reasonable and reliable, and would be of considerable referential importance in evaluating soil metal pollution.关键词
