Abstract
An introduction was made on the principle and modeling method of ARIMA(p,d,q)model. According to the annual precipitation characteristics of Tiandong County in recent years,ARIMA(1,1,12)model was set up for analysis and forecasting. The forecasting achievements were compared with that out of GM(1,1),showing that the precision of forecasting achievements out of ARIMA model is obviously higher than that out of GM.关键词
