摘　　要：地热能决定了地球分层流变、洋陆与盆山的关联成因、成矿成藏和自然灾害链,由此带动地学革命、能源革命和减灾革命。要实现这个宏伟目标,应开展两项重要工作:一是在地球系统动力学和热流体撞击地震成因模式指导下,科学预测地震及其关联灾害;二是在地球内部系统动力学和动态热源思想指导下,梯级综合开发地热能,特别是干热岩地热能低成本大规模持续发电,既能解决能源问题,又能从根本上解决灾害问题和环境问题。简要论述了地震与地热的关联机理,认为地球上没有板块,只有洋陆和盆山,它们由地壳和地幔固态流变物质层流而成,物质非均匀流动产生地震,断层是地震的结果。在热动力驱动地球物质非均匀层流的思想指导下,进一步阐明了地震预测和地热开发的思路和方法,明确指出沿着隐伏的活动韧性剪切带通过超长超导重力热管、U形钻井和U形挖掘进行高效采热,不仅能够解决供暖和电力问题,而且具有减灾减排作用。Geothermal energy determines the earth’s stratified rheology characteristics,the relevance between ocean-continent and basin-mountain,the mineralization,and the natural disaster chain,which will inevitably lead to revolutions in geoscience,energy,and disaster reduction fields.To achieve this ambitious goal,two important tasks should be carried out.One is scientific prediction of earthquakes and related disasters under the guidance of earth system dynamics and thermal fluid impact seismogenic model.Another one is cascade comprehensive exploitation of geothermal energy under the system kinetics and dynamic heat source inside the earth system instruction.It is remarkable that the hot dry rock geothermal energy is low cost and sustainable in large-scale power generation,which can solve the energy problem and the disaster and environmental problems fundamentally.The relevance mechanism between seismicity and geothermics was discussed.It is considered that there are no plates on earth but the ocean-land and basin-mountain as basic units formed by laminar flow of crust and mantle solid rheological materials.Besides,inhomogeneous laminar flow might generate earthquakes and also develop faults.Under the guidance of the idea that thermal dynamic power drives non-uniform laminar flow of earth material,the ideas and methods of earthquake prediction and geothermaldevelopment were clarified.It is clearly pointed out that using ultra-long superconducting gravity heat pipe,U shaped drilling and U shaped excavation along the underlying active ductile shear zone to efficiently collect heat,not only can solve the heating and power problems,but also help alleviating disasters and reducing the emission.
