In view of the uncertainty and ambiguity of groundwater quality evaluation indexes,the combination weight and normal cloud model are combined to establish water quality evaluation combination weight-normal cloud model which is applied in the comprehensive evaluation of groundwater quality.The indicator weight is calculated by using the utility value of data itself which is reflected through combination weight method,that can effectively avoid the difficult of weight allocation.The example calculation results of combination weight-normal cloud model are compared with the results of fuzzy matter element method and projection pursuit method.The comparison verifies that the model is rational,simple and practical.
