摘　　要：调查了甘肃景泰原生盐碱地枸杞（Lycium barbarum L.）园中土壤的水溶性盐分和离子组成。结果表明,栽培枸杞降低了10-100 cm土层水溶性盐分总含量,20-40 cm土层降低更明显;栽培枸杞对0-100 cm土层的盐离子产生不同的影响,降低了K^＋、Na^＋和Cl-的含量,但对Ca^2＋和SO4^2-影响不明显,Mg^2＋的含量反而增加。可见栽培枸杞降低水溶性盐分主要与一价离子有关。The soluble salt content and different salt ions content of soil were determined in an orchard cultivated Lycium barbarum L. , established on primary saline-alkali soil in Gansu. The soluble salt content in 10--100 cm depth soil layer decreased around root of Lycium barbarum L. , especially in 20-40 cm soil layer. Cultivating Lycium barbarum L. impacted on salt ions in 0-100 cm depth soil layer differently. Of all salt ions, K^＋ , Na^＋ and Cl^- content decreased, Mg^2＋ content increased,while Ca^2＋ and SO4^2- had little changes. So it is considered that planting Lycium barbarum L. in original saline-alkali soil decreased the soluble salt content from attribution of decreased univalent ions.
