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
