文章在野外考察、GPS定点和土壤采样分析的基础上,借助Excel、SPSS13等统计软件对新疆博斯腾湖周围白刺植物下土壤总碱度、盐离子含量以及盐离子间相关性作了探讨。结果表明,土壤pH值为8.47(平均值),呈碱性。在0~15cm土层盐分含量2.775%,15~45cm土层盐分含量4.506%,45~70cm土层盐分含量3.096%;不同深度的盐分含量依次为15~45cm>45~70cm>0~15cm,各阴离子含量为SO42->HCO3->Cl-,而CO32-在实验中未检测到,阳离子含量为K++Na+>Ca2+>Ma2+。在0~15cm土层Ca2+与K++Na+达极显著正相关,Ca2+与HCO3-呈显著正相关,Mg2+与Ca2+、K++Na+呈显著正相关,pH值与HCO3-、Mg2+呈显著反相关;在15~45cm土层Ca2+与K++Na+达极显著正相关,HCO3-与Cl-呈显著正相关,pH值与SO42-、HCO3-、K++Na+呈显著正相关;而在45~70cm土层Ca2+与K++Na+呈显著正相关,SO42-与Ca2+、K++Na+、Mg2+呈显著正相关。
Based on field investigation, GPS fixed point and soil sampling analysis, this paper discussed the relationship between soil total alkalinity, salt ion content and salt ions under the Nitraria plantation around the Bosten Lake in Xinjiang using statistical software such as Excel and SPSS13. The results showed that the soil pH was 8.47 (average), alkaline. The salt content in soil layer 0 ~ 15cm was 2.775%, the salt content in soil layer 15 ~ 45cm was 4.506%, the salt content in soil layer 45 ~ 70cm was 3.096%. The salt content in different depths was 15 ~ 45cm> 45 ~ 70cm> 0 ~ The content of each anion is SO42-> HCO3-> Cl-, while CO32- is not detected in the experiment. The content of cation is K ++ Na +> Ca2 +> Ma2 +. There was a significant positive correlation between Ca2 + and K + + Na + in 0 ~ 15cm soil layer, Ca2 + and HCO3- were positively correlated, Mg2 + was positively correlated with Ca2 + and K + + Na +, pH and HCO3-, Mg2 + ; Correlation between Ca2 + and K + + Na + in 15 ~ 45cm soil layer showed a significant positive correlation, HCO3- and Cl- showed a significant positive correlation, pH value was positively correlated with SO42-, HCO3-, K + + Na + There was a significant positive correlation between Ca2 + and K + + Na + in 45 ~ 70cm soil layer, and significant positive correlation between SO42- and Ca2 +, K + + Na + and Mg2 +.
