Abstract

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.

간척지 갯벌지반 식재 수목에 생장 저해하는 토양염분의 이동을 차단하는 염분차단재, 염분차단 위치 및 염분차단 두께에 따른 토양염분의 경시적 변화에 대하여 조사 분석하였다. 7가지의 토양염분이동 차단재료, 3가지의 차단두께 유형 그리고 토양염분이동차단 3가지 유형별로 염분의 변화가 다르게 나타났다. 갯벌지반은 초기에 토양염분이 높았으나, 점차 낮아졌다. 식생토인 객토는 초기에 토양염분이 낮았지만, 토양염분이동 무차단구에서는 점차적으로 토양염분이 높아졌고, 토양염분이동 차단구에서 전면차단구는 토양염분의 변화가 크지 않지만, 토양염분이동 벽면차단이나 밑바닥 차단만한 곳에서는 토양염분이 높아졌다. 토양염분은 강우시에는 토양염분이 낮아지나, 가뭄기에나 겨울철에는 토양염분이 높아지는 현상이 있었다. 토양염분이동 차단재료별 토양염분이동 차단능은 쇄석, 준설토, 목질칩이 다른 재료들 보다 우수하였다. 토양염분이동 차단벽은 최소한 20cm 이상 되어야 효과가 있는 것으로 나타났다.
