目前,地球表面各个圈层,如岩石圈、水圈、大气圈、生物圈等都相应地要进入一个新的活跃时期,各种自然灾害将频繁出现,人类正面临着各种自然灾害的严重威胁,因此全球环境变化是当前世界地球科学研究的焦点。这一问题的提出,其目的不仅仅在于观测发生在地球的岩石圈、水圈、大气圈和生物圈中的全球尺度变化,更为重要的是揭示这些变化的内在机制和 At present, all the layers of the earth’s surface such as the lithosphere, hydrosphere, atmosphere and biosphere are correspondingly entering a new active period. Frequent natural catastrophes will occur frequently and mankind is facing serious threats from various natural disasters Therefore, the global environmental change is the focus of the current earth science research in the world. The purpose of this question is not merely to observe the global scale changes in the Earth’s lithosphere, hydrosphere, atmosphere and biosphere, but more importantly reveal the intrinsic mechanism of these changes and
