摘　　要：根据我国学者原创的洋壳流力学,分析印度洋、大西洋洋壳流以一定的运动方向力作用与陆地、海岭相遇,必然产生相对应的具有鲜明特点的地形地貌,并绘出这两个区域洋壳流运行路线;结合太平洋洋壳流运行路线,细化出现代海底扩张运动运行路线的整体概貌,绘出了地球物质循环在地壳层的“毛细血管”;运用宏观统计的方式,得出洋壳流运动与陆地相互力作用的构造形迹力学性质的共性,由此推出现代全球地壳表面地形地貌的整体成因。更方便对全球地质运动给出更加合理、方便、细腻的解释。According to the theory of“mechanics of oceanic crust flow”originally proposed by Chinese scholars,when the Indian Ocean and the Atlantic Ocean crust flows meet with lands and ridges in certain direction of movement and force corresponding landforms with distinct characteristics inevitably will are produced,thus the routes of oceanic crust flows in these two regions may be plotted.Combining with the movement route of the Pacific Ocean crust current,a whole picture of the movement route of the modern seafloor spreading is refined,and the"capillary"of the earth material circulation in the crust layer is drawn.The general characters of the mechanical properties of the structural feature resulting from the interaction between the oceanic crust current and the land are obtained by means of macroscopic statistics.It is more convenient to give a more reasonable,convenient and delicate explanation to the global geological movement.
