| 摘 要： | 运用Matlab软件的FIS(Fuzzy Inference System)及相关函数,结合模糊综合评价方法,确立了土壤中Hg等6种重金属污染因子的隶属度函数。通过对Matlab-FIS-sugeno模型权重的归一化,使其适应于加权模糊型算子的模糊综合评价,从而拟建了基于Matlab-FIS-sugeno的土壤中重金属污染模糊综合评价模型,并利用该模糊综合评价模型对铜陵有色金属矿区农田土壤中的重金属污染状况进行了评价;评价结果与实际情况比较吻合。

| Abstract: | By using the fuzzy inference system(FIS) and related functions of Matlab,fuzzy comprehensive assessment of six heavy metal elements including Hg,Cd,As,Pb,Cu and Zn in the soil of the Tongling mining area is carried out.The weighted fuzzy operator is adopted,and the weight of the Matlab-FIS-sugeno model is standardized.A fuzzy comprehensive assessment model of heavy metals in contaminated soil is built based on the Matlab-FIS-sugeno model.The assessment results agree well with the actual situation.The presented method is simple,quick,accurate and visualized,and both the single element assessment result and the comprehensive assessment result can be shown clearly. |
