| 摘 要： | 在黑龙江省均有季节冻结和季节融化现象发生，多年冻土区有季节融化层，季节冻结层主要分布在多年冻土区以外的地区。按季节冻结类型可把黑龙江省季节冻土分为过渡型、半过渡型、长期稳定型和稳定型等类型。季节冻结和融化深度在年际间有很大的差异，在多年冻土区南界附近，季节冻深年际间变化最大。土季节冻结和融化的影响因素主要有雪盖、植被、土壤成分及含水量、地表状况和地形等。

| Abstract: | The phenomenon of seasonal freezing and seasonal thawing happen all arou nd our province.Seasonal thawed layer is in permafrost region;seasonal fr eezing layer distributes mainly the rest of permafrost region.Accordin g to the type of seasonal freezing,the seasonal frozen ground can been divided into intergradati on,semi -intergradation,long -term stability and stability.Seasonal freezing and thaw depth vary in different years.The biggest is n ear the south edge of permafrost region.The factors that can influence the soil seasonal free zing and thawing include snow -cover,vegetation,the soil component and contain water,the condition of earth,landform and so o n. |

| Keywords: | seasonal thawing seasonal freezing thawing depth freezing depth the course of freezing and thawing the in-fluencing factors |
