Environmental Quality Assessment by Fuzzy Mathematics Method Yang Wendong Assoc.Prof.,School of Resources and Environmental Engineering,WUT,Wuhan 430070,China.It's necessary to make the atmosphere environmental quality assessment, on which a series of judgments depend. Also the assessment offers the preliminary data to evaluate the environment trend. This paper assesses the atmosphere environmental quality with the method of fuzzy comprehensive judgment, builds weighting average mathematics model, and develops a program based on C++. This program is successfully applied to analyze and evaluate the atmosphere environmental quality in recent years of Wuhan city.atmosphere environmental quality assessment; fuzzy comprehensive judgment; mathematical model;\ program
