        冰是冰冻圈核心物质，但不同冰冻圈要素因冰的含量及其他物质组成有所不同，物理性质及各种物理过程存在明显差异。经过20世纪中后期对冰的物理性质的大量实验研究和冰冻圈主要要素物理特征的广泛调查，冰的物理性质和冰冻圈主要要素物理特征的基本概念得以明确。随着冰冻圈科学体系的建立和服务于社会经济发展的需要，冰冻圈物理研究在3个方面要着力发展：（1）提高冰和冰冻圈要素物理性质的定量刻画精度，为过程模拟、冰冻圈灾害防治和冰冻圈服务提供关键参数支持；（2）加强冰冻圈主要要素综合物理过程的模拟研究，特别是要开展实体和相似性模拟实验；（3）推进冰冻圈多模式及其与其他圈层模式的耦合研究。

        Ice is the core material in cryosphere, while the physical properties as well as physical processes of cryospheric components vary obviously because of difference in ice proportion and other material compositions. A large number of laboratorial studies and extensive field investigations in the middle and late of 20th century have determined the basic concepts of ice physical properties and the outlines of physical characteristics of these cryospheric components. With establishment of the cryospheric science system and requirement of the socio-economic development, research emphasis of cryospheric physics should be put on three aspects in future. One is further investigation of ice physical properties in details in order to provide accurate parameters for modelling, disaster prevention, and cryospheric service. Another is the laboratory simulation of combined processes of the cryosphere, especially entity and similarity simulations. The third is to promote the coupling between cryospheric models and further between models of cryosphere and other spheres.
