摘要
运用水化学和同位素方法研究了鄂尔多斯沙漠高原大克泊湖淖地区地下水与湖水转化关系,结果表明:大克泊湖淖地区地下水来源于大气降水,并受到不同程度的蒸发作用影响;浅层地下水在大克泊湖淖四周接受降水补给,向大克泊湖淖流动,受到溶滤、蒸发、沉淀、蒸腾作用,沿地下水流方向水化学类型表现出分带性,由HCO3-Ca.Mg型水向HCO3.Cl-Na型水演化;地下水最终补给湖水,运用稳定同位素质量守恒方程估算地下水补给湖水量占总补给量的57%。
Groundwater-lake transformation in the Dakebo Lake region of the Ordos desert plateau is studied by the method of the hydrochemistry and isotope.The results show that the groundwater in the lake region comes from the precipitation,under the influence of the evaporation on different degrees;while,the shadow groundwater around the lake accepts the precipitation recharge,with its flow discharge to the lake,during which the hydrochemistry type takes on the characteristics of belts along the flow direction from the HCO3-Ca·Mg type to the HCO3·Cl-Na type under the function of lixiviation,evaporation,precipitation and transpiration;after all above,the groundwater finally recharges the lake,and the quantity of the recharge was also evaluated to be 57% of the total recharge with the sable isotope mass balance equation.
