Abstract��
Soil salt transformation plays an important role in the freeze-thawing process��which is also one of basic problems of cryopedology�� The very special law is made up of the two time salt-moisture transfer under freeze-thawing condition�� Based on the latest research at home and abroad��through the investigation of soil moisture-salt change in the freeze-thawing process��the conclusion is made that the soil water potential gradient is the main driving force of soil salt movement and the factors are of quantities�� The research shows that��when freezing��temperature drops��salt and moisture move towards frozen layer�� All make the salinity content of the frozen layer increase significantly�� In the thawing process��salinity and moisture in the soil move up again with evaporation and makes the salt second migration�� |
