Abstract：For determining the covariance function in the collocation model for analyzing crustal deformation a new method considering the physical characters and spacial attribute of crustal movement is proposed, into which the calculated deformation value is introduced and centralized and the determination is made in different regions and different directions. Using the observed data and combining the robase estimation we have established the more representative covariance function model of the horizontal movement of the main blocks of China continent.By use of this model the calculated results can be interpreted more reasonably.
