In this paper, several related questionsare discussed together with the general principles of fuzzy mathematics in environmental differentiation.And on the above base, some improved methods are put forward, and applied to some calculations（takethe examples of water quality assessment）. The results indicate that the new methods are more practicable. 模糊数学 综合评判 累积频率 相对距离法 fuzzy mathematics comprehensive diffreretiation accumulated frequency method of relative distance X-65 1998-05-01 2021-04-01 5
