中文摘要	利用天山北坡季节性冻土区的军塘湖流域观测场2013年和2014年冻融期冻土深度及各层土壤的温湿度数据,研究季节性冻土的冻融规律及冻融过程中土壤含水量的变化特征,探讨各层土壤水分分布及迁移特征对融雪径流的影响。结果表明:冻融过程中冻土深度会发生变化,且温度不同冻融速率不一;土壤水分的迁移受制于土壤温度的变化,特别是表层10cm土壤温湿度相关性极大;对比2013年,2014年数据,土壤表层10cm内的含水量变化会对融雪水的下渗有调控作用,从而影响下垫面的径流量。研究季节性冻土冻融过程及对融雪径流的影响,会对准确预报融雪性洪水有重要意义。
英文摘要	The freezing thawing process and variation of soil moisture were analyzed with the measured data of temperature and soil depth with each layer in Juntang Lake Basin on the northern slope of Tianshan Mountains in seasonal frozen soil area during the period from 2013 to 2014.Both freezing and thawing process within seasonal frozen soil was investigated,and the effect of soil moisture distribution and migration characteristics in different layers on the snowmelt runoff was examined.The results showed that the process of freezing and thawing permafrost depth changed,and the temperature of different freezing and thawing rate was not a subject;migration of soil moisture and soil temperature was subject to change,correlation between soil temperature and humidity in surface 10cm was significant;the correlation between the ground temperature in 10cm above snow surface and soil moisture in 10cm depth was analyzed in 2013(R=0.924),and 2014(R=0.908).Compared to the data of 2013 and 2014,the changes in seasonal frozen soil surfer moisture played the regulatory role in water infiltration,soil moisture transferred between the surface and underground, in the meantime,the migration of soil water had the impact on the seasonal freezing-thawing process,and resulted in the generation of snowmelt flood.The results revealed that there was the significant correlation between these factors.So study on freezing and thawing process of seasonal frozen soil and effects on snowmelt runoff has the important significance to forecast snowmelt flood,and the results can be used for the modeling and prediction of spring snowmelt flood in the Juntang River Basin.
