In this study, the ²H and ¹⁸O isotopes of soil water and chemical composition of soil solution was analyzed for six typical soil profiles in the Badain Jaran Desert. Our results showed that the degree of the evaporation effect increased gradually from the southern to the northern of this desert. Local precipitation was the main recharge source for the soil water, deep soil water should be originated from the mixture of the heavy precipitation and shallow soil water. Recharge source and chemical weathering were the two major mechanisms to control the ion concentrations of the soil solution in this desert.

干旱荒漠非饱和带土壤溶液稳定同位素(δ18O和δ2H)及化学特征

本研究对巴丹吉林沙漠六种典型土壤剖面的土壤水的² H 和¹⁸ O 同位素和土壤溶液的化学成分进行了分析。我们的研究结果表明，蒸发效应的程度从该沙漠的南部到北部逐渐增加。局部降水是土壤水分的主要补给来源，深层土壤水分应来源于强降水和浅层土壤水分的混合。补给源和化学风化作用是控制该沙漠土壤溶液离子浓度的两大机制。
