| 摘 要： | 青藏高原多年冻土作为我国冰冻圈的重要组成部分， 其水热状况是影响寒区生态环境、 陆气间水热交换、 气候变化以及地面路基建设等的重要因素。为增进对青藏高原多年冻土区活动层水热特性的认识， 对影响活动层水热特性的主要因素以及主要研究方法做进一步梳理， 并指出了当前研究中的不足。研究认为， 气象条件、 植被覆盖度、 土壤性质、 积雪等是影响多年冻土区活动层水热过程的主要因素， 目前针对活动层水热特性的研究主要通过对站点实测资料分析和模型模拟等方式展开。未来工作的重点应放在改进适合于高寒山区的陆面模式以及增强水热动态过程与气候系统的相互作用上。

| Abstract: | As an important part of China’s cryosphere， the hydrothermal condition of the permafrost on Qinghai-Tibet Plateau is an important factor affecting the ecological environment of cold regions， the exchange of water and heat between land and air， climate change and the construction of embankment. In order to enhance the understanding of the hydrothermal characteristics of the active layer in permafrost regions of the Qinghai-Tibet Plateau， this paper summarizes the main factors that affect the hydrothermal characteristics of the active layer and the main research methods， and points out the main problems in the current research. It is believed that meteorological conditions， vegetation coverage， soil properties and snow cover are the main factors affecting the hydrothermal process of the active layer. At present， researches on the hydrothermal characteristics of the active layer are mainly carried out through the in situ measured data and model simulation. The future work should focus on improving the land surface model suitable for alpine mountains and enhancing the interaction between hydrothermal dynamic processes and climate system. |
