Abstract

Abstract: Under the coupling effect of temperature field, moisture field and artificial canals, the structure of soil can be easily changed by the heat transport and water migration process, which leads to regional ecological imbalance and secondary salinization. Four typical salinized areas including Nong'an, Da'an, Qian'an and Zhenlai were selected as long-term monitoring and evaluation areas. Under the multi-field condition, saline soils with different cover strata were collected and investigated in the field. The engineering geological properties, physico chemical properties and composition of studied soil were tested and monitored. The results showed that the saline soil in western Jilin belonged to carbonate saline soil, and the amount of water migration was about 3.5%-4.6%. Salt content generally decreased with increasing depth, and the distribution of water and salt in the profile obviously was affected by season. The effect of evaporation in dry season and soil freezing caused salt to move up with the water, and a large amount of salt gathered at the soil surface. With the increasing depth, the cation exchange capacity presented the same trend as salt content.

Key words: saline soil in western Jilin Province, material composition, physicochemical properties, salt content
