摘　　要：在综合分析前人资料和系统梳理笔者认识的基础上,以整体观和系统论的思想为指导,针对板块构造学说存在的核心科学问题,采用分尺度、分层块、分阶段的研究思路,探讨开放复杂地球系统的物质运动方式。将水平运动与垂直运动相结合,流体运动与固体运动相结合,地球内部过程与外部过程相结合,探索盆山和洋陆的成因及其关联机理,认为热动力是驱动盆山地壳物质循环和洋陆壳幔物质循环的关键因素。开放地球系统存在与盆山、洋陆物质循环有关的水循环、火山物质循环、大气循环、碳循环、生物地球化学循环、洋流循环,由此产生资源、能源、灾害、环境效应。地球内部热能经过长期的积累之后,以超级干旱-火山-冰冻-地震-洪水-海平面上升组成的全球性巨灾链形式释放,具有时空结构和关联机理的巨灾连发导致生物分批死亡,集群绝灭。地质历史上还有无数规模较小、结构相似、机理相同的热灾害链,不同程度地影响地球生态环境和全球变化。热灾害链贯穿地球整个演化过程。根据下地壳流动规律和热灾害链时空结构对中国大陆强震进行了预测。强调取热减灾减排不仅能够解决能源危机,而且可以降低灾害强度,推迟灾害发生时间。On the basis of a comprehensive analysis of previous data and a complete summary of the my ide as, under the guidance of holistic view and system theory, this paper investigates the motion pattern of the opening complex Earth system in different spatial and temporal scales against the key scientific problems of plate tectonics. Origin and evolution of basinmountain, oceancontinent and their associated mechanism are explored by the research ideas of combination of horizontal and vertical motion, fluid movement and solid movement, process of the Earth＇s interior, external and surface, and it is considered that thermody namics is the key factor of crustal material recycling between basin and mountain, and crustmantle materi al recycling between ocean and continent. Water tion, carbon cycle, biogeochemical cycles, ocean cycle, volcanic material circulation, atmospheric circula circulation related to the basinmountain and ocean conti nent material recycling exist in the open Earth system, and yield resource, energy, disaster, environmental effects. Earth＇s thermal energy is released in the form of super disaster chains consisted of giant drought volcanofrozenearthquakefloodsrising sea levels after a longterm accumulation, and many giant disasters with timespace relationship and associated mechanism resulted in the biological death in batches, and mass extinction. During geological time, numerous smaller thermal disaster chains with similar structure and same mechanism as giant thermal disaster chains also affect the Earth＇s ecological environment and global change in different degrees. Thermal disaster chains run through the whole evolution process of the Earth. Strong earthquakes in mainland of China are predicted according to regular pattern of lower crustal flow and temporal spatial structure of the thermal disaster chain. Development of geothermal energy not only can solve the energy crisis, but also can reduce the intensity of disasters and delay disasters.
