Due to the increasingly serious water pollution of the Yangtze river, the discharge of waste water increases year by year, the water pollution problem is very serious, environmental protection is imminent. In this paper, we study the water quality assessment and prediction, based on the analysis of the conditions and data, the fuzzy comprehensive evaluation method to make quantitative analysis, the quality of the water in the Yangtze river and one dimensional water quality model to calculate two kinds of the main sources of pollutants, finally using the linear regression equation to predict the amount of sewage after ten years, and made the solution.


Keywords: Equation of linear regression; One dimensional water quality prediction model; Fuzzy comprehensive evaluation
