摘　　要：地球上一切物质都是做开合运动的。以热力(热能)驱动物质上浮运动定义为开;以重力(势能)驱动物质下沉的运动定义为合。开合运动具有垂直开合与水平开合的同步统一性和开合相互依存、相互对立、相互转化两个重要特性。因而在旋转运动的统领和调剂下,将所有地球物质、构造、能量等从无序状态转化到有序状态,最后建成了动态稳定平衡的开合旋构造体系。所以,动态稳定平衡体系的形成、破坏、修复不断旋回式演化就是研究地球内部运行的基础和有效方法。为此,我们在垂向上划分了8个开合构造旋回和地壳(球面)开合构造体系,组成了地球四维运行系统。动态稳定平衡体系的建立是遵循重力均衡准则、最小内能原理(结晶化)、几何优选方位(垂直地心)生长和横向物质均匀化4条自然规律的长期作用而实现的,其中重力均衡是主导的。大约40亿年时,地幔岩石圈形成,它像一个球形锅盖盖住热地球,初步建成了稳定的开合旋构造体系,使地球长期进入动态稳定平衡发展阶段。尔后,每次重大地质事件(失衡运动)就是把岩石圈地幔捅个窟窿或撕开一条裂缝,破坏该地区的开合平衡。旋转运动和开合运动迅速将其恢复达到新的平衡,从而构成一个开合旋回,目前地球已经历了8个大旋回。板块构造仅研究最新4个旋回的岩石圈地幔是如何被捅破及被修复的规律并总结相关的理论,因而它在时间上和空间上都有局限性,不属于全球构造。地球类比为一个生命体,其运行系统中的内部结构和功能比较齐全:包含有开合运动、旋转运动和失衡运动组成的运动系统;起"血液"作用的地质流体、贮存和制造"血液"的"心脏"--地核和联系各种"血液"的地幔柱组成的"血液"系统;以重力均衡为准则,由四个重力均衡面、四个开合转换带和球面两条质量均衡线构成的地球平衡系统。�All Earth materials and processes perform opening and closing movements.The thermally(heat energy)driven upward movement can be defined as opening,while the gravity(potential)driven downward movement can be defined as closing.The overall opening-closing movement achieves synchronized unity and interdependency between vertical and horizontal movements through mutual opposition and transformation.So that,under rotational control and modulation,this movement transforms all Earth materials,tectonics,energies,etc.from the state of disorder to order,and eventually builds up the dynamically stable and balanced opening-closing-rotating tectonic system.Therefore,studying the unceasing cyclic evolution of formation,destruction and renovation of this dynamically stable and balanced tectonic system is the only basis and effective way for understanding the working of the Earth’s interior.For that,we delineated eight vertical and one crustal(spherical)opening-closing tectonic cycles,and preliminarily established a 4-dimensional working system of the Earth.The dynamically stable and balanced system is established through long-term working of the four natural laws,i.e.,gravity balance,internal energy minimization(in crystallization),preferential growth orientation(normal to the Earth’s center)and horizontal homogeneity,among which gravity balance is the leading law.At about 4 Ga,mantle lithosphere was formed as a lid covering the hot Earth.This event initiated the stable opening-closing-rotating tectonic system and entered the Earth into a prolonged dynamically stable and balanced evolutionary era.After that,each major geological event(loss of balance)had been either poking a hole into or tearing up the lithosphere,thus destructing Earth’s balance.But the rotating and opening-closing movements could quickly restore the balance and start a new cycle.Till now the Earth has passed through eight megacycles.Since plate tectonics only concerned with the destruction and restoration of the most recent four megacycles in developing
