摘要
在季节性冻土分布区,土壤水分的冻结和融化必将会伴随着热量交换、水分迁移等物理过程。通过分析影响土壤季节性冻结、融化的主要因素,论述了季节性冻融土壤中热量交换、水分迁移等物理过程以及季节性冻融过程中土壤水、热迁移的研究进展,并提出存在的问题。
Freezing and melting of soil moisture associated with heat exchange and water migration in distribution area of seasonally frozen ground.The article analyzing factor of seasonal freeze thawing of soil,elaborated on physical process of heat exchange water migration in the course of seasonal freeze thawing and advances in soil moisture and thermophoresis research,proposed the questions.
