Application of multipolar fuzzy pattern recognition based on mixed attribute to water quality evaluation

Pointed to the problems of current multipolar fuzzy pattern recognition method depended on testing time and the evaluating result for the water qulity not complete,this paper introduces a multipolar fuzzy pattern recognition method based on mixed attribute to completely evaluate the water quality.Comprehensively determining the weight of each index and combined with the environment factors affecting the water quality,this method has realized the predictive function on water quality evaluation,which did not depend on testing time totally,and can provide a more accurate basis for scientifically and reasonably decontaminating the water pollution.The examples have shown that the result of evaluating water quality by this method was reasonable.
