The damage caused by the salt weathering is one of the biggest problems at soil ruins. Understanding the rules of soluble salt content and concentration in soils can provide theoretical and technical support for soil site conservation. Soil columns were prepared in plexiglass containers having EM50 detectors to study the moisture content and conductivity of the soil column longitudinally at different depths. The results were used to understand the type and migration of various salts in the soil column. It was found that the lower the moisture content, the greater the conductivity. Ion chromatography showed that Na⁺, Mg²⁺, Ca²⁺, Cl- and SO2-₄ contents all change together with salinity at various depths. This study provides a theoretical reference for the soil ruins management.
