Improvement and Application of Fuzzy Probabilistic Method

The fuzzy probabilistic method is a general evaluation method of regional environmental quality. It is popular in the general evaluation of regional atmosphere environment, water environment, and so on. As the fuzzy probabilistic method requires a great deal of data on the studied area, it is inconvenient for environmental evaluation. To enhance the practicability of this method, this article improves the 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 a lot of time and money in the course of sampling and can increase the efficiency of environmental evaluation. The authors can see that the improved method is an effective method for general evaluation of environmental quality.
