Table 1 Resource gradients division of soil factors. The same values in adjacent grades are assigned to the lower grade.
表1土壤因子梯度等级划分。相邻等级中相同的值划入低等级。

On the basis of preliminary evaluation with Fuzzy Mathematics method, we achieve the comprehensive evaluation of soil quality of Taiyuan Basin and classify the contaminative grades finally.
在利用模糊数学评价法分别进行初步评价的基础上，最后进行太原盆地土壤质量综合评价和污染等级分类。
