Research and Prediction of Yellow Soil Moisture Content in Guizhou Province Based on ARIMA Model

Abstract

To predict the change trend of guizhou yellow soil moisture content, we employed the ARIMA model of time series, compared the measured data with the prediction data, and the results show that ARIMA time series model fitting soil moisture content change trend is good, predicted value is very close to the observed value. The maximal absolute error, 0.6% and the maximal relative error, 4.2%).The results have practical application value for drought research and management to provide reference[1].
