挤压推覆造山与拉张伸展成盆的转化成因机理概括为：褶皱—逆冲带临界楔角制约与重力蠕滑作用；增温，岩石圈热膨胀隆升减薄作用；剥蚀，重力均衡调整作用以及由于地球表面积的基本守恒而造成的岩石圈板块空间上的挤压收缩与拉张伸展的相互转化作用。强调岩石圈板块是一个不断与外界进行能量交换的开放性体系，因此上述转化实质上具有无序、随机的混沌性，但另一方面它们又受天体（包括地球本身）运行规律的宏观制约，从而又具有有序、确定的分形性。地球上山—盆转化受此控制，成为复杂的自组织系统。该系统可以用非线性多元函数方程定性描述。

The transformational mechanisms between thrust-pressure orogeny and tension-extending basin-forming can be concluded as:(1)the restrict out of the critical taper of the fold-and-thrust belts and the gravitational creep-sliding, (2)the lithosphere’s uplifting and extending out of the heat rising after thrusting, (3)eroding and gravitational adjusting and (4)the transformation between interplates for compressional shorting and extensional spreading out of the essential conservation of the earth's surface area. Since the lithosphere plates and the earth are all the open systems which exchange enegy with outer space continuously, so the transformation mechanisms mentioned above have a feature of chaos nonlinearly and randomly. But on the other hand controlled by the celestial body(include earthself) motion law macroscopically, they have another feature of fractal orderly and determinately. It is a complicate auto-organizational system which can be described with a multi-element and nonlinear function equation.

Key words: Orogen-basin transformation mechanism, Bulldozer model, Gravitational function, Lithosphere thermodynamic adjusting, Celestial body motion law control, Open auto-organization system.
