| 摘 要： | 通过对比苏打碱土上无植被"碱斑"和临近有植被的"草地"土壤水分、离子变化规律,研究了碱土各种离子及其与土壤pH、EC的关系.结果表明:即使在极端干旱的气象条件下,地下水对地表水补给能力仍然很强,地下水参与土壤盐分运动的现象明显.碱斑土壤pH高于草地;在高水分条件下,pH的峰值出现位置在地表下30 cm,土壤干旱过程,p... |

| Abstract: | Comparing the change regularity of soil moisture and ions on no vegetation base spot and vegetation near a grass of sodic soil,the relation of soil pH,EC and the ions were conducted.The result showed that the supply capacity of groundwater to surface water was still strong,the phenomenon of groundwater participating soil salt movement was obvious,even under the extremely draught condition.The pH of base pot was higher than that of grass.In high water condition,peak of pH was in subsurface 30 cm,and when soil drought,peak of pH was in the subsurface between 10～20 cm.EC of different period gradually reduced with soil depth,and the peak of EC was in the subsurface between 0～20 cm.EC value of base pot was higher than that of grass.The pH and EC of soil were significant positive correlation with CO2-3,SO2-4,K＋,Na＋ concentration,and had no significant correlation with HCO-3,Cl-,Ca2＋,Mg2＋ concentration. |
