摘要
通过对河西地区盐渍化草场土壤水分、盐分动态的观测分析，结果表明：随着外界条件的变化，土壤水分的变化主要发生在０～４０ ｃｍ 范围内，４０ ｃｍ 以下基本保持稳定；土壤盐分随着水分的变化基本也在０～２０ ｃｍ 范围内上升或下降运动；地下水位在１２～１８ ｍ 之间变化。
Through observation for the dynamics of soil water and salt movements in saline grassland of Hexi regions,the result shows that water movement in the profile mainly occurred in 0～40 cm soil layer and salt movement occurred in 0～ 20 cm layer in natural condition. Underground water table is changed in range of 1.2～1.8 m and water salt is great.
