榆林沙区盐渍化土地水盐运动规律研究

本文根据实测资料,分析了定边县周台子乡东梁村水盐运动的变化特征,结果表明,该区全年处于积盐状态,由于季节的不同,积盐差异较大,盐分的表聚性强;该区土壤盐分含量还表现出随地形不同而变化,地势高,地下水位低,土壤盐分含量低,随着地势的降低,地下水位升高,土壤盐分含量也随着增加。

Water and Salt Movement in Salted Land of Yulin Sandy Area

According to the measured data,analysis salt and water movement in Dongliang village,Zhoutaizi township,Dingbian county,the results show that the state of salt in the area throughout the year,due to seasonal differences,large differences in salt accumulation,salt accumulation of strong;the area of soil salt content was also shown vary with the terrain,high elevation,low water table,soil salt content is low,with the lower-lying water table rise and soil salinity levels increase significantly.
