| 摘 要： | 物元分析方法应用到土壤质量评价研究中，以土壤质量等级、评价指标及其特征值构造物元，通过建立模型的经典域、节域、权重集和关联度函数，采用层次分析法计算各评价指标的权系数，并根据计算出的综合关联度来实现对各土壤样本的质量等级综合评判与排序。模型被应用到松花江地区21种土壤样本的质量等级评价与排序中，取得了较好的效果。

| Abstract: | The author applies matter element model based on stratification analysis method in soil quality evaluation.This method takes the grade of soil quality standard, evaluating factors and its characteristic value as matter elements. Through establishing the standard units, the partial units, weight aggregation and relational function of matter element model and adopting stratification analysis method, the writer achieves on evaluating grade of the soil samples and its optimum order according to the synthetic relational degree.The model is applied to 21 soil samples in Songhuajiang Rigion.Good result and effect are obtained. |
