文章对自张掖、酒泉等地区碱茅草地和盐渍荒地耕层土壤（０～４５ｃｍ）采集的２１个样品进行了全盐含量、有机质、ｐＨ和八大盐离子分析测定，在此基础上，用参数区间估测法求得了碱茅草地与盐渍荒地的总体平均数差异。结果表明碱茅草地土壤全盐含量明显降低的同时，主要有害盐离子的含量及比例也有所降低，其中Ｎａ￣＋降低０．９６～４．９６ｍｅ／１００ｇ土，Ｍｇ（２＋）降低０．３５～２．２５ｍｅ／１００ｇ土，降低０．２５～５．６９ｍｅ／１００ｇ土，可使Ｎａ￣＋＋Ｋ￣＋／Ｃａ（２＋）＋Ｍｇ（２＋）降低０．０９～０．８５倍，、及ｐＨ无影响。
In this paper, 21 samples collected from soils and soils (0 ~ 45cm) in soils and soils of saline soils in areas of Zhangye and Jiuquan were analyzed by analyzing the contents of total salt, organic matter, pH and eight salt ions. On the basis of this, The method of parameter interval estimation obtained the difference of the total average of the alkali thatch grasslands and saline wasteland. The results showed that the total salt content of Alkali grassland decreased significantly while the content and proportion of the main harmful salt ions also decreased. Na¯ + decreased 0.96 ~ 4.96me / 100g, Mg decreased 0.35 ~ 2.25me / 100g soil, reducing 0.25 ~ 5.69me / 100g soil, can make Na ~ ++ K ~ + / Ca (2 +) + Mg influences.
