冰冻圈科学体系的建立及其意义

Establishment and Significance of the Scientific System of Cryospheric Science

冰冻圈是气候系统五大圈层之一,其存在和变化对大气、水资源和水循环、生态系统、陆地和海洋环境以及社会经济可持续发展具有重要影响,在地球系统中扮演重要角色。从冰冻圈形成和变化机理与过程,与大气圈、水圈、生物圈和岩石圈相互作用,到冰冻圈变化的影响和适应,以及区域和全球经济社会的服务功能等的集成,发展成一门新兴交叉学科——冰冻圈科学。冰冻圈科学体系的建立和发展,与“未来地球”“地球委员会”等倡导的方向相一致,具有国际前瞻性。

The cryosphere is one of the five major spheres of the climate system.It plays an important role in the earth system with its huge fresh water reserves,latent heat of phase transitions,greenhouse gases,and unique species and cultural structures.The formation,change mechanism,and process of cryosphere;the interactions with atmosphere,hydrosphere,biosphere,and lithosphere;the influences and adaptations of cryosphere change;the service functions for regional and global economy and society all together have rapidly developed into a new interdisciplinary discipline,which is called Cryosphere Science.Being consistent with the directions advocated by the“Future Earth”and the“Earth Commission”,the establishment and development of the scientific system of the Cryosphere Science is internationally forward looking.
