The model of ecological footprint on water resources was applied to calculate water resources from 2003 to 2012 in Shanxi Province. At the same time, the model of ARIMA was used to prospect ecological footprint of water resources in Shanxi Province from 2013 to 2017.The re-sults showed that the model of ARIMA(2,1,1) could better fit the change of ecological footprint on water resources from 2005 to 2012.And the prediction error of per capita ecological footprint change was not more than 10%.It was suitable to predict and simulate the change of ecological footprint, and the prediction accuracy could be improved.
