| 摘 要： | 大盐滩作为柴达木盆地重要的液体钾盐赋存地之一,开展卤水水文地球化学研究能够有效指导钾矿的合理、长期开采。利用改进的Collins图、相关性系数、变异系数及离子等值线图等地球化学分析手段,探讨了该地区卤水水化学变化特征及影响因素。结果显示,目前该地区的卤水类型均为Cl-Na型;研究区内主要卤水化学成分变异程度不大,Na~+及Cl~-在空间上呈东北高、西南低的分布特征,其余离子均表现出反向的分布规律;研究区内地球化学特征变化除了受到溶滤作用影响外,还在很大程度上受到卤水开采及淡水补给的影响;卤水开采及淡水补给从某种程度上改变了沉积层的物理结构,使地层渗透系数的不均匀性增强;人工淡水补给能够渗入到卤水潜水层中,从而增加可开采卤水量,但对卤水矿化度的影响情况尚不明确。
