摘　　要：通过将空间取样点和时间取样点相结合,对Fuzzy概率法进行改进.安庆某工程大气环境质量综合评价实例研究结果表明:改进后的Fuzzy概率法模型可行,原理简明、运算量小,在保证评价结果的可靠性的同时,节约了大量取样过程的时间和费用,节约了环境评价所需资金,环境评价的效率得到明显提高.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.
