比较行星空间物理

Comparative Planetary Space Physics

空间物理学日趋成熟,既丰富了人类对地球和行星空间的认识,也引申出更具挑战性的问题。一些涉及行星演化问题的解决倚赖与其他学科的交叉探索,要求研究者从行星地球的视角出发,把地球视为一个从地核到磁层的多圈层耦合系统。作为系统外层环节的空间环境,其中的问题可通过比较行星研究的思路找到突破口。基于学科交叉的比较行星空间物理研究将是未来空间物理学的一个重要发展方向。阐述比较行星空间物理研究的思路和必要性,梳理研究现状,并展望研究前景。

It has been 60 years since the space physics as new branch of geophysics started to grow in 1957 when the space age was opened by a small satellite called sputnik. The knowledge of Earth and planetary space has been significantly extended and deepened,but the questions we are facing today are more challenging. A consensus reached is that we have to regard the Earth（planet） as an integrated system including all spheres from the inner core to the magnetosphere,and we should try to investigate some questions standing on the ground of interdisciplinary study,especially those questions related to Earth＇s（planetary） evolution. Space environment as the outer part of a planetary system,commonly exists in all planets but also exhibits strong diversity. Here,we introduce the short history of basic ideas and methods of comparative study,the advantages on understanding of some issues of global scale,and the prospect from comparative perspective.
