The invention provides a vibration and noise reduction shielding door for an urban rail transit station platform, which belongs to the technical field of shielding doors for subway stations. The shielding door comprises a sunken structure, which is arranged on the surface of the shielding door according to the type, the material and the size of the shielding door in combination with a main frequency band needing noise reduction. By reducing the vibration of the shielding door, radiation noise, caused by vibration, of the shielding door is reduced, and the stability and firmness of the shielding door are improved; therefore, resonance is avoided or reduced, and then vibration of the shielding door is weakened; radiation noise generated in the subway station is reduced, the sound environmentcondition of the platform layer is improved, the vibration of the shielding door is weakened, the interaction force between the shielding door and the ground of the platform layer is also reduced, and the firmness and stabil
