Abstract

Abstract:

It is known that the traditional rigid plate rotation motion model(RRM) can not take into account the deformation of the intraplate,which is up to now seems to have been solved by the overall rotation with homogeneous strain model(REHSM).However,there is still limitation in describing the deformation of the intraplate because of that the "homogeneous" assumption is difficult to be satisfied in many complex geological tectonic regions.Therefore,a new model of REHSM improved by least square collocation is presented to enable the model of REHSM to have a wide applicability.The results of the analysis of the velocity field data of the recent GPS observations from "China Tectonic Environment Monitoring Network" in the Bohai sea area show that it is feasible and more reasonable to use the new model to analyze the crustal deformation.

Key words: crustal movement, homogeneous strain, linear strain, least squares collocation
