%X The tidal gravity observation achievements obtained in Hong Kong area are presented, the first complete tidal gravity experimental model in this area is obtained. The ocean loading characteristics are studied systematically by using global and local ocean models as well as tidal gauge data, the suitability of global ocean models is also studied. The numerical results show that the ocean models in diurnal band are more stable than those in semidiumal band, and the correction of the change in tidal height plays a significant role in determining accurately the phase lag of the tidal gravity. The gravity observation residuals and station background noise level are also investigated. The study fills the empty of tidal gravity observation in the Crustal Movement Observation Network of China and can provide the effective reference and service to ground surface and space geodesy.
