针对传统的土壤环境重金属受污染程度评价标准不统一、定性指标难以定量化的问题,建立了适用于土壤中Cd等重金属污染状况评价的模糊数学模型。应用Matlab软件的Matlab-FIS工具分析了白银市白银区附近的土壤中重金属污染情况,评价结果显示该区域土壤受到了一定程度的重金属污染,采样点中层土壤受污染程度高于表层土壤,远离工业区的土壤质量好于工业区附近的土壤。研究表明,模糊评价法可以精确地对土壤中重金属综合污染进行评价,解决了传统的单因子指数评价法存在的不足之处,比单因子指标评价法更为客观、准确。
針對傳統的土壤環境重金屬受汙染程度評價標準不統一、定性指標難以定量化的問題,建立瞭適用于土壤中Cd等重金屬汙染狀況評價的模糊數學模型。應用Matlab軟件的Matlab-FIS工具分析瞭白銀市白銀區附近的土壤中重金屬汙染情況,評價結果顯示該區域土壤受到瞭一定程度的重金屬汙染,採樣點中層土壤受汙染程度高于錶層土壤,遠離工業區的土壤質量好于工業區附近的土壤。研究錶明,模糊評價法可以精確地對土壤中重金屬綜閤汙染進行評價,解決瞭傳統的單因子指數評價法存在的不足之處,比單因子指標評價法更為客觀、準確。

Fuzzy model has been established which suits for Cadmium in the soil and some serious heavy metal pollution , in view of lack of unity and quantification for quantitative indicators for the evaluation standard of heavy metal pollution .Mat-lab-FIS in the Matlab model was used in analyzing the soil heavy metal polluton in Baiyin nearby .The evaluation result showed that a certain degree of soil heavy metal pollution has been suffered in this area .The degree of the contamination in the middle soil was higher than in the surface , the soil quality away from the industrial area was better than the nearby are-a.Studies also showed that ,Fuzzy evaluation method can accurately evaluate the comprehensive pollution of heavy metals in soil,which overcomed the shortcomings in the traditional single index evaluation method .It is more objective and accurate than the single factor index evaluation method .
