摘　　要：开合运动是地球上一切地质体运动的基本形式。由于开合运动同步统一的特征,它包容了垂直运动与水平运动,故开合运动的内涵更深,应用更广;由于开合运动的相互转换特征,垂直运动也是动态相互转换,很难确定地球或某个地区的开与合或垂直运动与水平运动的主次关系,只能按某一阶段它们的主次关系进行构造分区,在这种分区中,按垂直运动与水平运动观点划分的构造单元往往不能反映构造的本质特征,因而建立在垂直运动与水平运动之上的固定论和活动论之争无实际意义。开合运动的相互转换特征及转换带的时空定位有重大的理论和实践意义。开合运动和旋转运动是地球最基本、最重要的运动形式,合称为开合旋运动,在它的长期作用下形成动态的、相对稳定的层圈结构和各种地质构造,称之为开合旋构造体系,开合旋构造体系一度或局部被破坏,经调整达到新平衡的过程称之为地球构造运动,因此构造运动是突发的、短暂的、区域性的;而将充满地球时空、重要非凡的开合旋运动叫地球运动。地球构造运动的内因主要是热能和重力能,核幔交接区是以热能和重力能为主的综合能量形成和聚集的基地,是地球构造运动的策源地。开合运动是地球的本质特征,旋转运动是地球形成及演化的必要条件,开合旋运动塑造了一个内容丰富、生机勃勃、动态发展的开合旋构造体系。Of all geological body movements,opening-closing movement is the major form of the Earth.Due to the synchronism and unity characteristics of the opening-closing movement,including both vertical and horizontal movements,the movement intension should be much deeper and thus the opening-closing movement should have a wider application.Under this condition the controversy between fixism and mobilism based on vertical and horizontal movements should be of little practical significance.The mutual transforming characteristics between opening and closing movements and the spatial positioning of the transformation zone are of great theoretical and practical significance.Opening-closing and rotationing movements are the most important essential forms of the Earth′s movement and can be,in brief,named as opening-closing rotationing movement.Under the long term effort of this movement the relatively stable,dynamic spherical layering and various geological structures are formed,known as the opening-closing-rotationing tectonic system.The once or local destruction of the this tectonic system can be readjusted to reach a new equilibrium.This process is known as Earth＇s tectonic movement.Therefore,a tectonic movement is paroxysmal,temporal and regional;and the extraordinary important opening-closing-ratationing movement widespread in time and space in the Earth is named as Earth movement.The internal factor of the Earth tectonic movement is thermal energy and gravitational force energy.The core-mantle boundary is a comprehensive base for the forming and accumulating of thermal energy and gravitational force energy which is the hotbed of the earth tectonic movement.Opening-closingmovement is the substantial property of the Earth.Rotational movement is the prerequisite for the formation of the Earth.Opening-closingratationing movement has modeled a rich content,full of vitality and dynamically developing opening-closing-rotationing tectonic system.
