Abstract: The problem of reservoir life is of fuzzy characteristics,it can be studied and predicted throughfuzzy analysis,In this paper,the reservoir life is considered as the object of analysis,the parametersof analysis are as follows:Watershed area,first storage capacity,annual average sediment deposit vol-ume annual average drainage erosion thickness. According to the data of ten reservoirs in Taiwan,fuzzy mathematical model is found.On the basis of this,the reservoir life of two reservoirs is predict-ed. The results are satisfactory.

Key words: reservoir life, fuzzy mathematics, subordinate function
