Heating of magnetized plasma through one towards mutiple shear Alfvén waves with low frequency propagating along background magnetic field is studied with test particle simulation.It shows that mutiple waves whose frequencies match resonance condition lead to significantly efficiency heating by strengthen non-resononce process. With evolution of heating, mutiple waves turn to modulation wave. As frequencis of mutiple waves are close wave packets are created in transverse direction. A great ion temperature anisotrophy is produced and after that randomization process is stengthened either. Efficiency of stochastic heating process is also enhanced.It can be used in controling non-resonance and stochastic heating process by changing frequencise of mutiple low frequency waves.
