Improvement and Application of Fuzzy Probabilitic Method

Fuzzy probabilistic method is a general evaluation method of regional environmental quality.It is popular in general evaluation of regional atmosphere environment,water environment,and so on.As fuzzy probabilistic method requires a great deal of data of the studied area,so it is inconvenience to the environmental evaluation.To enhance the practicability of fuzzy probabilistic method,this article improves fuzzy probability method by integrating sampling points of space and time.Result from a case study shows that the improvement is feasible with concise theory and less calculation.With good reliability,this method can save much time and money in the course of sampling and increases the efficiency of environment evaluation.The conclusion is drawn that the improved method is an effective method of general evaluation of environmental quality.
