| 摘 要： | 给出由最优权法确定各评价因子的权重,采用模糊识别方法对土壤重金属污染进行评价,避免了确定各指标权重时的主观任意性,增加了评价结果的分辨性.利用该方法对南充市区土壤进行评价,得到的结果符合南充市区土壤的实际情况.

| Abstract: | This paper quantifies the weights of different evaluation indexes with optimizing weight ap- proach,and evaluates heavy metal pollution to soil by fuzzy recognition method,which can avoid the sub- jective randomicity and increase the distinguishability of result.Nanchong city is evaluated with this meth- od and it's result is accorded with facts of Nanchong. |

| Keywords: | fuzzy recognition optimization weight method soil heavy metal pollution |
