最初，cryohydrology被称为涉及低温的水文学，例如，雪，冰，冻土和冷水的水文研究。这门学科随着冰冻圈科学的发展而扩大，现在涉及到各种冰冻圈要素的水文过程，系统地与流域水文过程相结合。然而，从冰冻圈科学的角度介绍冰冻水文学的特点和学科内涵的研究却十分有限。回顾了低温水文学内涵的演变，分析了低温水文学的水文学基础和学科体系。得出了三个主要结论。(1)冰冻水文学是在传统的冰冻圈单一要素水文学的基础上发展起来的，重点是冰冻圈的水文功能及其对水循环和向其他球体供水的影响。(2)低温水文学的水文学基础可概括为水源涵养、径流补给和水文调节。其中，水源涵养功能主要表现为“淡水源”和“寒湿岛”，径流补给功能主要表现为供水功能，调节功能主要表现为年内和年际尺度。(3)低温水文学的核心研究问题是研究方法、水文过程、流域功能和区域影响。低温水文学的重要特征是水的频繁相变和在空间和时间尺度上的高变异性。冰冻水文学旨在加深对其机制和过程的理论和认知水平的理解，准确量化流域的水文功能，促进对冰冻圈生态和环境影响的理解。
Initially, cryohydrology was referred to as hydrology involving low temperatures, for example, the hydrological study of snow, ice, frozen ground, and cold water. This discipline broadened with the development of cryospheric science and now involves hydrological processes of various cryosphere elements systematically coupled with river basin hydrological processes. However, limited studies have introduced the characteristics and discipline connotations of cryohydrology from a perspective of cryospheric science. Here, we reviewed the evolution of the connotations of cryohydrology and analyzed its hydrological basis and discipline system. Three major conclusions were drawn. (1) Cryohydrology was developed based on traditional hydrology for a single element of the cryosphere and focuses on the hydrological functions of the cryosphere and its impact on the water cycle and water supply to other spheres. (2) The hydrological basis of cryohydrology can be summarized as water conservation, runoff recharge, and hydrological regulation. In detail, the water conservation function is primarily expressed as “source of freshwater” and “cold and wet islands,” the runoff recharge function is concerned with water supply, and the regulation function is effective at intra- and inter-annual scales. (3) The core research issues of cryohydrology are research methods, hydrological processes, watershed functions, and regional impact. The important characteristics of cryohydrology are frequent water phase transitions and high variability across spatial and temporal scales. Cryohydrology aims to deepen the understanding of the theoretical and cognitive levels of its mechanisms and processes, accurately quantify the hydrological functions of the basin, and promote understanding of the ecological and environmental impacts of the cryosphere.
