    Abstract:

    In order to reveal the influence of decreasing range of freezing air temperature (DRFT) and soil texture on soil temperature variation and soil moisture migration with shallow groundwater, three freezing schemes, less DRFT, medium DRFT and larger DRFT, were conducted with the groundwater level depth of 87.5cm, and the temperature and moisture content of sandy loam and silty clay loam were monitored. The results showed that the surface temperature of sandy loam was lower than that of silty clay loam freezing by less DRFT, medium DRFT and larger DRFT about 0.88℃, 2.06℃ and 2.81℃, and soil profile temperature reached steady decreasing stage in 31d, 33d and 37d respectively. Soil moisture of sandy loam mainly gathered at the depth of 10cm to 30cm and that of silty clay loam gathered at the depth of 10cm to 40cm. Soil moisture of sandy loam at the depth of 0cm to 10cm freezing by less DRFT was higher than that freezing by medium DRFT and larger DRFT about 1.5% and 7.3%, while it was 2.3% and 2.7% respectively for silty clay loam. 
