基于熵权的属性识别模型在土壤重金属污染评价中的应用

Application of Attribute Recognition Model Based on Coefficient of Entropy to Comprehensive Evaluation of Soil Heavy Metal Pollution

综合考虑了熵权赋值的客观性以及属性识别模型在解决有序分割问题上的优越性,本文将基于熵权的属性识别模型应用于土壤重金属污染评价中,并用此模型对乌鲁木齐市主要蔬菜基地的土壤环境质量进行评价,结合实际,将其结果与模糊数学模型评价结果进行比较,表明此模型用于土壤重金属污染评价方法可行,且精确度高。

Considered the entropy of the objectivity and assign attributes recognition model in addressing the issue of the orderly division superiority, the attribute recognition model based on coefficient of entropy is applied to evaluate heavy metal pollution of the soil, and use this model to evaluate the soil environmental quality of the main vegetable bases in Urumqi. Compared the results of attribute recognition model and fuzzy mathematical models, and it shows that this model for evaluating heavy metal in soil is feasible and high precision.
