| Abstract: | Due to the complex and multi power factor characteristics of vertical crustal movement, it is not effective to approximate the velocity field by simple model. In this paper, we propose two integrated approximation models:two step combining model and weighted combining model to approximate the vertical crustal deformation field. We have approximated the vertical deformation field of Bohai Gulf with these two models and obtained some satisfactory results.The results imply that the methods proposed in this paper have the theoretical and practical values. |
