Abstract：Fuzzy recognition can be used to judge the hydrological year similarity for the lake when the hydrological forecasting precision of the lake is low, the historical regulation experience of the lake can be used to as current dispatching scheme if the hydrological similarity year can be found, euclidean distance of lake runoff、 lake level and water consumption betewen recognition dates and the historical is selected as e-valuation index,Similar standard and the method of fuzzy recognition for hydrological year similarity judg-ment is also built. By calculation the euclidean distance of the three index, the problem is changed to judge similarity degree case study show that the methed has broad application prospect.
