Considering the difficulties of calculation using fuzzy synthetic evaluation method and the relationship among evaluators are ignored, a new weight evaluation process using entropy method was established. Aiming at the water quality assessment of the Three Gorges reservoir area, the differences of Entropy method and traditional method was compared in the weight calculation of evaluating indicators by using the fuzzy mathematics. The results showed that when there were one more evaluators, using this method was very convenient for fuzzy synthetic evaluation. Only one calculation was enough and it need not to calculate every monitoring point. This method predigested the fuzzy synthetic evaluation process greatly and the evaluation results were reasonable.
