摘要：

在综合分析大量地质、地球物理资料的基础上，建立了以热能为驱动力的开放地球系统发生多级物质循环的地球系统动力学新模式，据此可以合理地解释洋陆系统及其相关的盆山体系的动力学机制，阐明地球系统资源灾害环境发展的内在关系。在地球系统动力学创新思想指导下，总结了活动地壳热构造系统的特征，初步研究了华北和西南热灾害链的结构和强震发展趋势，系统地分析了取热减灾减排的重要性、必要性和可行性，在此基础上阐明了系统开发干热岩的思路和方法及其可持续发展的途径。从而为即将到来的新地学革命和能源革命提供了一个新思路。

关键词: 地球系统动力学, 取热减灾减排, 干热岩开发, 能源革命

Abstract:

On the basis of a lot of geological and geophysical evidence, a new model of earth system dynamics is proposed as the multistage cycle in the open earth system driven by thermal energy for reasonable explanation of dynamic mechanism of oceancontinent system and related basinmountain system and the interaction of resource, natural hazard, environment and economic growth. Under the guidance of innovative ideas of earth system dynamics, a comprehensive summary of the feature of thermal tectonic system in active crust，preliminary study of the structure and earthquake trends of happened and ongoing thermal disaster chains in the North China and Southwest China, and a systematic analysis for the importance, necessity and feasibility of reducing disaster and emission by development of geothermal energy reveals ideas and methods for development of hot dry rock geothermal energy, and new way of sustainable development. Therefore this paper suggests a new idea for coming new earth science revolution and energy revolution.

 

Key words: earth system dynamics；reducing disaster and emission by development of geothermal energy, development of hot dry rock, energy revolution
