  • In order to overcome subjective and erroneous tendency problem of experts determination method in comprehensive water quality evaluation,this paper sets the attribute recognition model of water quality for groundwater sources based on entropy weight by Chen Qiansheng’s attribute recognition theory.The entropic coef-ficient of water quality assessment indicators is determined by using Shannon entropy theory.In the model,firstly,the author establishes the attribute space matrix and determines the weight based on Shannon entropy theory;sec-ondly,calculates attribute measure;thirdly,evaluates that with confidence criterion and score criterion;finally,an application example is given.The results of this model and the SPA model have good consistency.
