| 摘 要： | 冻土是全球中高纬地区和高山地带普遍存在的自然现象,它对全球以及区域性气候、水循环、水平衡等都有着巨大的影响,土壤冻融条件下的陆面过程正是这种影响的重要环节,介绍了土壤冻融条件下陆面过程的研究现状,特别是在大气环流模型(GCM)中引入水文陆面模型以来陆面过程研究的迅猛发展,对现在国际上正在进行的考虑冻土的陆面过程研究项目,如陆面过程参数化比较计划的第二阶段第五期PILPS(2E)以及美国NASA的寒区陆面过程实地试验计划也进行了介绍,并在此基础上对土壤冻融条件下陆面过程的发展趋势进行了分析.

| Abstract: | Freezing soil is a natural phenomina in cold and mountain areas,which has great impact on the regional climate,water cycle,and water balance.The land surface process in the condition of soil freezing and thawing is one of the most important process in the area.This paper firstly reviews the present study on land surface process in the condition of soil freezing and thawing,especially the development after the the hydrological land surface model introduced into the study of General Circulation Model, then introduces the undergoing international research project,such as Project for Intercomparison of Land-surface Parameterization Schemes and Cold Land Process Field Experiment by NASA,and finally analyses and puts forward the future research field and topics. |
