柴达木盆地南缘诺木洪地区地下水具有西北干旱盆地地下水水化学特征及分布规律,受盆地地貌、强烈蒸发极干旱气候条件控制和含水层岩性、埋藏条件、地下水渗流场的共同影响,形成了高山深盆特有的地下水水化学水平分带性。文中对地下水水质类型的形成演化过程进行了探讨,并就此类盆地地下水水化学类型缺失硫酸盐型水环带的成因机理进行了分析。
The groundwater in the Nuomuhong area on the southern margin of the Qaidam basin has the hydrochemistry characteristics and distribution rules of the groundwater in the northwestern arid basin. Affected by the geomorphology of the basin, the control of intense evaporative arid climate conditions, lithology of aquifers, burial conditions and groundwater seepage fields, Formed a unique high-altitude deep basin water chemical horizontal zonation. In this paper, the formation and evolution of groundwater quality are discussed, and the genetic mechanism of the absence of sulfate type aquifer in the basin is analyzed.
