    The continent of China and its adjacent land and marginal seas were formed by convergent and collided of a series of sub-plates and blocks in the late Paleozoic. Since Mesozoic the lithosphere in east part of east Asia was broken up and thinning,the asthenosphere upwelling forming the giant rifts system,whereas in west part the Indian lithosphere collided with Eurasia in Paleocene causing the crust to be shortened and uplifted. The structure and evolution of lithosphere are very complicated.
    We collected the newly geophysical data and other geospaces data in China and adjacent land and sea regions for inverting the fine three-dimensional structures Earth model with multi-discipline researches and various inversion methods. The high-resolution three-dimensional Earth model and database in the area will be built and provided a reference model for applied in individual geosciences fields.
    It aimed to discover the structure of lithosphere and asthenosphere,the three-dimensional velocity and physical properties in transition zone to core-mantle boundary. To study the interactions between sub-plates and blocks of lithosphere,the deep dynamic processes of the mantle convection,layered coupling. A detail discussion has been made for the structure and interaction of lithospheric blocks,especially for the deep dynamic processes collision and thicken of lithosphere in west part and the extension and thinning in east part.

Key words: Deep geodynamics., China and its adjacent land and sea regions, Three-dimensional layered Earth’s model
