In order to obtain data fitting and prediction effect of the wood fiber length of natural forest of mono maple based on a time series model,with the radial variation pattern of the time series model as a research object,the autoregressive fractional integrated moving average model(ARIMA) of the time series model is used for data fitting and medium and short-term prediction.The research result shows that the model ARIMA(0,1,1) can be used to realize the data fitting and prediction of the wood fiber length of natural forest of mono maple,with good model fitting data and five-year short-term prediction accuracy higher than ten-year and twenty-year medium-term prediction accuracy.
