Abstract：The long term prediction of Earth rotation parameters were performed by using LS+AR combing model, fluid excitation functions including atmospheric angular momentum and ocean angular momentum, respectively. Numerical tests showed that the prediction precision computed from fluid excitation functions was better than those from LS+AR combing model, and the prediction precision from atmospheric angular momentum excitation function was better than those from ocean angular momentum.
