|According to the thesis of fuzzy hydrology that there exists no definite limits between clean and polluted waters but fuzzy characteristics in the process of the recognition, the authors present the following fuzzy mathematic model of lake water environmental assessment and rank:??? The model is applied to the rank of the eutrophication situations for J2 lakes in China* and the results are in agreement with the facts.Moreover,the model is suitable to the assessments in other environmental fields.
