摘要
地球科学最新研究成果表明,地表物质运动与核幔边界的大规模能量交换过程密切相关,地球动力系统平均温度的演变具有由高到低的整体趋势。越来越多的证据表明,地球内部处于非绝热状态,正在持续进行的地球冷却过程将对地表环境产生重大影响。人类对地球内部热源的开发尽管可以使地表短时期迅速增温。
The recent achivements of earth science have shown that the surface matter movement is close relative to the large scale energy exchange on the boundary between the core and mantle, the development of avarage temperature in earth dynamical system. The more and more evidences prove that the inner earth is non adiabatic and the lasting cool process will have a great influence upon the surface environment. Though developing heat resoures in inner earth make the surface temperature rise quickly in short time, it brings about the lasting quick cooling in the inner earth.
