摘　　要：本文对希夏邦马浅冰芯的资料进行了分析,发现离子含量变化显示强烈的周期性变化.反映了季节变化的特征.离子浓度高低变化将指示气侯的冷暖变化,并与降水量变化有着反相关关系,与δ^(18)O存在着对应关系,但δ^(18)O对气候变化的反映没有各种离子TC反映灵敏.Based on the analysis of chemical data in a shallow ice core in Xixiabangma,Tibetan Plateau, it is found that the variations of anions and cations in the ice core are characterized by obvious seasonal periodicity. The variation of ions in ice core reflects the climate fluctuation, and shows negative correlation with precipitation. 8 18O in ice core show corresponding variation with various ions, but is less sensitive to climate change than that of ions.
