【目的】解决青海高寒区盐碱地治理的问题。【方法】采取在青海柴达木盆地德令哈（中度盐渍化）与诺木洪（重度盐渍化）2处试验区建设排盐工程与田间试验的方法，在中度和重度盐渍化土地安装毛细透排水带与暗管进行排水，分析了毛细透排水带降盐技术对中度和重度盐渍化土壤盐分变化规律的影响。【结果】①中度和重度盐渍化土壤表层（0~10 cm）盐分下降最快，其他土层盐分量呈现显著下降，中度和重度土壤最高脱盐率分别为81.19%和96.62%，重度盐渍化土壤盐分可降低至中度水平；②2处试验区0~10 cm土壤盐分中Cl-、SO42-、Na+和K+量较原始土样明显下降，毛细透排水带对Cl-、SO42-、Na+和K+有显著的淋洗作用；③毛细透排水带降盐技术在青海高寒区中度盐渍化地区土壤脱盐率可达98.61%，重度盐渍化...
