Abstract :
This paper introduced fuzzy assessment of water quality based on membership grade by artificial neural network. Samples were obtained by intensive interpolation of water quality standards, relative MG matrix was output as expectation value for network´s train and application. Then, improved fuzzy mathematics method was applied to assess the water quality of Qingdao Dagu River.
