摘　　要：本文选取花花柴（Karelinia capsia（Pall.）Les.）覆盖下的不同地貌盐碱土为研究对象,采用土壤常规离子测定和传统的统计学分析方法,对6-9月不同样地各层土壤可溶性盐离子的动态变化特性进行分析。结果显示：（1）玛纳斯河流域中游泉水溢出带到河流下游荒漠5块样地不同月份土壤含盐量显著不同,142样地Na^＋和K^＋含量显著高于其他样地。136样地Na^＋含量最低。Ca^2＋离子含量在136样地中始终处于最低。Mg^2＋在5块样地中含量高低依次为134〉141〉142〉135〉136。（2）沿玛河流域中游一直到下游,土壤盐分表现为由高到低,其中Na^＋含量呈现典型下降趋势,到沙漠区含量极低。（3）玛纳斯河流域中下游不同地貌土壤因其盐分离子的相互作用加之差异的气候和地下水等影响表现出了不同的盐离子含量和各异的动态变化规律。This study selects the saline-alkali soils in different landforms which are covered by Karelinia capsia（Pall.） Les.as the research object,analyze the dynamic changes about soluble salt ions in different depths of soil with general ion determination of soil and traditional statistical analysis methods from June to September.The results showed that：（1） Five plots of soil salinity in different months were significantly different from the middle to lower of the Manas River,Na^＋ and K^＋ content of 142 plot were significantly higher than the other plots.Na^＋ content of 136 plot were the lowest.And Ca^2＋ content in the 136 plot were the lowest too.Mg^2＋ content in the five plots were 134〉141〉142〉135〉136.（2） Soil salinity especially Na^＋ content showed typical decline and the lowest in desert from the middle to lower of the Manas River.（3） The soil in five landforms had different salt ion content and the dynamic differ that were impacted of interaction between salt ions and differences in climate and groundwater.
