%X According to the respective characteristics of polar motion and length of day,combining LS and AR model,a suitable prediction model for the Earth Rotation Parameter(ERP) was builded.In order to reduce the strong correlation,the difference before establishing AR model was down and ERP 1-10 days were predicted.The results show that the prediction accuracy has reached an international leading level.
