地学发展若干问题及对策

一、目的 地学包括地质学、地理学、地球物理学、地球化学、大气科学、海洋科学,以及环境科学、空间科学、生态学和资源问题的一部分,其中大部分是自然科学中最早形成的一些学科,有着悠久的发展历史;而另有一些则是由于当代技术发展和人类面临要解决的重大问题的需要而应运产生的新学科。所有这些学科和它们的若干分支在当代都有着蓬勃的发展,起着越来越大的作用。

SOME PROBLEMS IN GEOSCIENCE DEVELOPMENT AND COUNTERMEASURE

Symposium on some problems in geoscience development and caumtermeasure was convened by the Geoscience Division of Chinese Academy in Beijing in November 22-24, 1990. Some important basic problems of geoscience which have potential important significance to geoscience development were dis cussed at the symposium, they are :1. comparative planetology;2. deep ocean researches;3. deep Earth interior studies;4. present tectonic motion and dynamics;5. microphysical-chemical problems in minerals and in petrogenesis, metallogenesis;6. low-temperature geochemistry;7. palaeoenvironment and palaeoclimatology of the Earth;8. living beings evolution and the origin and evolution of human beings;9. ocean circulation and ocean dynamics;10. studies of thd basic theory of atmospheric physical and dynamic processes;11. the study of the dynamic change of the cryosphere;12. the general process of Global climate system;13. the interaction between Geosphere and Biosphere;14. Earth fluid dynamics and geoscience numerical simulation;15. the basic research of remote sensing in geoscience;16. the modulation study of Earth crust and man-Earth system .
