综合土壤重金属污染评价的单因子综合指数法、内梅罗综合指数法和地积累指数法的优点，以重金属含量平均值、毒性指标、变异系数和相关性四个因素建立层次分析结构图，通过构造成对比较矩阵，计算出了单因子综合指数法、内梅罗综合指数法和地积累指数法三种方法在土壤重金属污染评价中的综合权重，利用综合权重对土壤重金属的污染程度进行了排序和评估。
綜閤土壤重金屬汙染評價的單因子綜閤指數法、內梅囉綜閤指數法和地積纍指數法的優點，以重金屬含量平均值、毒性指標、變異繫數和相關性四箇因素建立層次分析結構圖，通過構造成對比較矩陣，計算齣瞭單因子綜閤指數法、內梅囉綜閤指數法和地積纍指數法三種方法在土壤重金屬汙染評價中的綜閤權重，利用綜閤權重對土壤重金屬的汙染程度進行瞭排序和評估。

In this paper, soil heavy metal pollution including the single factor index method, inside, the comprehensive index method, and to accumulate index method was evaluated respectively. Using the advantages of them, the heavy metal content in average, toxicity index, and coefficient of variation and correlation of four factors were selected to establish analytic hierarchy structure. By constructing the paired comparison matrix, soil heavy metal pollution comprehensive weights in these three methods were calculated. Degree sorting and evaluation were given by the comprehensive weight of soil heavy metal pollution.
