By means of cations(Ca 2+ ,Na +,Mg 2+ and K +),anions(Cl -,SO 4 2- and NO 3 -),pH value and conductivity of snow and ice from the Guliya ice cap,the feature of arid dust influence on the cap is discussed in this paper.

• 从雪冰样品中的阳离子（Ca2＋、Na＋、Mg2＋和K＋）、阴离子（Cl－、SO42－和NO3－）、pH值、电导率等几个方面分析了干旱区粉尘对古里雅冰帽中化学记录的影响特点。
