摘要:

吐鲁番盆地是我国西北干旱区内陆盆地之一,盆地内赋存铁矿等重要矿产资源。研究吐鲁番盆地地表水和地下水化学成分的演化对于吐鲁番盆地地下水资源的合理开发具有重要意义。采用无机离子示踪剂的方法,通过主要离子浓度与Cl-离子浓度之间的关系,以及主要离子/Cl- 与Cl- 离子浓度之间的关系,对盆地地表水和地下水的主要化学成分的形成进行了分析。同时参照地表水中主要化学成分的形成与演化,揭示盆地地下水化学成分的演化过程以及盐分的潜在来源。在吐鲁番盆地,影响不同深度地下水水化学变化的主要是蒸发矿物,其来源主要包括土壤表面的蒸发矿物、土壤层和包气带中的蒸发矿物以及艾丁湖中的表层沉积物。

Abstract:

Turpan Basin is one of the inland basins in Northwest China, which is rich in major mineral resources (e.g. iron ore). Investigation of the formation and evolution of chemical composition in groundwater and surface water in Turpan Basin is critical to the utilization and protection of groundwater in this region. In this study, inorganic ion tracer method was employed to analyze the relationship between main ions and Cl- or main ions/Cl- and Cl-, and the formation of major chemical composition in surface water and groundwater in Turpan Basin was also investigated. Furthermore, the evolution of chemical composition and the potential source of salt in groundwater in this region was also illustrated. Based on this study, it was found that evaporate minerals in Turpan Basin is the major factor that could affect the hydrochemistry changing of groundwater in different depth.  The evaporate minerals in this region are mainly derived from the surface soil, soil layer, vadose zone and Aydingkol Lake sediments.

Key words: Turpan Basin, surface water, groundwater, hydrochemistry, evaporate mineral, soluble salt
