摘要
In this paper,the weight of evaluation indicator difference is obtained by calculating entropy.Using the concept of the ordered partition class,the attribute recognition model based on coefficient of entropy is established.By selecting indicators of TDS,COD,total Fe,total Mn,Cl-,SO42-,NO2-and F-,the shallow groundwater quality of the southern suburbs landfill of kaifeng is evaluated with the attribute recognition model based on coefficient of entropy.The results show that the water quality evaluated with the attribute recognition model based on coefficient of entropy is better than the results of the comprehensive evaluation.
