The achievement and new progress in geodesy and geophysical inversion in the recent decade are summerized in this paper.There are many models of geodesy joint inversion based on mechanical pattern.The model identification is preliminarily discussed.Developing an inverse analysis model based on the Global deformation data is presented in IAG2001.Various local optimization methods and global optimization methods (like genetic algorithm and IA algorithm) are developed. The numerical manifold method (NMM) is also introduced into geodesy joint inversion.Both the finite element method (FEM) for continual and the discontinuous deformation analysis (DDA) for block systems are special cases of this numerical manifold method. We can estimate bottom ocean topography with gravity data using the integrated inverse method,obtain the complete horizontal motions within zones of distributed deformation from the inversion of strain rate data and study recent crustal deformation and strain accumulations inferred from GPS and seismicity data.We can also detect active fault segment with joint inversion of observed gravity and GPS baseline changes and study the crustal movements with various observations including geodetic,geological and seismic.
