根据古里雅冰帽中的ＳＯ２－４离子主要来源于陆地地表矿物的事实，以及干旱少雨的内陆地区可溶性硫酸盐分布范围广，在地表矿物中含量的变化主要受气候条件，特别是干湿程度所控制的自然现象，提出了用古里雅冰芯中的ＳＯ２－４离子推断该冰川作用区的干湿变化。用古里雅冰芯的ＳＯ２－４离子推断出的该地区小冰期以来的干湿变化，与冰芯中冰川积累量和δ１８Ｏ所反映的干湿变化相一致 Based on the fact that SO2-4 ions in Gurli ice caps are mainly derived from terrestrial surface minerals and that the arid and inhospitable inland areas have a wide distribution of soluble sulfates, the content changes in surface minerals mainly depend on climatic conditions, especially on wet and dry Degree of control of the natural phenomenon, proposed using Gully ice core SO2-4 ions inferred that the role of the glacier wet and dry changes. The dry-wet change in the area from the small-ice age deduced from the SO2-4 ion in the Guli ice core is consistent with the ice accumulation in the ice core and the change in wet and dryness reflected by δ18O
