摘　　要：根据目前地球物理、地球化学、地质学及行星地质等研究的成果，本文讨论了地球演化的内外因素，并提出了一种新的地球结构模式。笔者认为，地球是一个相对开放的系统，其内外层圈之间的作用过程存在密切联系，地球层圈的分化融合作用决定了地球的演化及变动过程。最后，通过对软流层分化融合作用的分析，提出了一种陆缘扩张盆地演化的新模式，并对第二次造山及软硬碰撞等问题做了概略的讨论。According to the new researches of geophysics,geochemistry, geology and so on,the interior and exterior factors on the evolution of the earth have been discussed. A new model of the stucture of the earth has been put forward. The earth is a relatively open system,and there is a close link among its layers and spheres. The differentiation and assimilation of the layers and spheres of the earth have played a decisive rule in the evdlution and alteration of the earth. Finally, the authors bring forward a new model on the evolution of the spreading basins in continental margins through the analyses of differentiation and assimilation of the astheno spkere. The seeond orogenesis and soft-hard collisions and the like,are also discussed broadly here.
