1 INTRODUCTION
This paper predicts Poyang Lake’s water level, it is the basic of influence research. Once there were many predicting methods, such as ANN [1,2], etc. But these methods are not very precisely. This paper uses wavelet analysis to decompose water level series, then it uses ANFIS to modeling the decomposed series, in the end it combined these series.
