This study was carried out to figure out on the changes of longitudinal salt movement in the soil through the soil according to the materials and thickness of salt prevent materials and the place of salt prevent at reclaimed land from the sea which is one of the most serious problems when tree planting. Changes of soil salinity were different depending on the seasons. In particular, the soil salinity was lower during the rainy season. But during the dry seasons including early summer before the rainy season and winter season, salinity was relatively higher. Among the seven interruption materials, crushed stone, dredged sand and wood chips showed better interruption effects than the other materials. The interruption effect of salt movement was highest in the both of side and bottom interruption treatment of salt movement than the side interruption treatment of salt movement or the bottom interruption treatment of salt movement. The thickness of the layer should be at least 20cm to prevent salinity effectively.
