天山东部冰芯pH值和电导率的大气环境空间差异

Abstract:
冰芯电导率是大气环境变化的替代性指标。对我国天山东部三个研究点奎屯哈希勒根48号冰川、乌鲁木齐河源1号冰川以及哈密庙儿沟平顶冰川粒雪芯中pH值和电导率的近期环境记录进行了分析研究。结果显示，三个研究点粒雪芯反映的近期pH值和电导率变化趋势不同奎屯电导率随冰芯深度增加表现出升高趋势，哈密庙尔沟平顶冰川和乌鲁木齐河源1号冰川随冰芯深度增加表现出一定下降趋势；冰芯电导率平均值在哈密庙儿沟冰川最大，而其他两个点相对较小，这与矿物粉尘浓度和离子浓度的分布一致；雪冰电导率与粉尘及离子相关性分析表明，电导率主要受中亚粉尘活动影响,同时与Ca2+、Mg2+、Na+等相关性很高。通过比较显示，天山东部与我国西部其他研究点以及极地雪冰电导率的差异可以很好地反映大气环境的空间差异。
