摘要: 本文从热学原理和系统科学观点出发,论述了冻土热学的基本概念和冻土系统研究的学科框架.把冻土系统分为冻土工质系统、冻土层系统和冻土区域系统三个层次,分析了各个层次的基本运动形态和规律,根据各层次的特点给出了其热学唯象理论.热力学和统计力学分别从宏观和微观研究物质系统的热学性质.本文把热力学和统计力学的平衡态理论用于冻土Ⅰ质系统;把线性非平衡态理论用于冻土层系统;把非线性热力学和非线性统计力学的发展为解决冻土演化问题奠定了基础,以上几方面文中给出初步的讨论.同时从自然地理学和物理的交叉性出发,针对一些冰缘现象,力求为冻土学的理论与应用提供一幅物理学图景.

Abstract: Based on the principle of thermology and the system science point of view, the author analysed conception of geocryology thermology and shown the structure of researching method. Geocryo-system can be divided into three levels:geocryo-soil material level , geocryo-layer level and geocryo-region level. Depend on the special properties at every level, the author given the geocryo-system mechanisiously theory. We sure that thermology analysis method shall play important rule in researching the evolution of geocryo-system.
