This paper introduces the method of Projection Pursuit the idea, principle, modeling steps and application of the model in water quality evaluation of Dehuixin river. Use the Real-code Accelerating Genetic Algorithm to optimize the problem and then comparing the result with other results of Pollution Index Method and Fuzzy Evaluation Method. It shows that the method of Projection Pursuit can better evaluate the water quality, its result has higher objectivity and authenticity through the calculation, analysis and comparation.
