| 摘 要： | 在确定评价因子、评价标准、数学模型、模糊关系矩阵和权重因子的基础上,运用模糊综合评价法对焦作市市区土壤重金属污染状况进行了评判.对44个监测点的评价结果表明：29个监测点低于三级标准,2个监测点三级水平,1个监测点二级水平,12个监测点一级水平.进一步进行聚类分析可清晰地看出样品点所属的类,使综合评价结果更加合理,为土壤污染治理提供了依据.

| Abstract: | Based on the determination of evaluation factors, evaluation standard, mathematical model, calculating fuzzy relationship matrix and weight factors, the fuzzy comprehensive evaluation method was applied to evaluate soil quality in Jiaozuo city. The results showed that 29 sites were heavy contaminated, 2 sites were middle contaminated, 1 site was low-grade contaminated and 12 sites were cleanness. Furthermore, the kinds of soil samples were classified by cluster analysis, which made the results of comprehensive evaluation more satisfactory. |
