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.
In this paper, the data of Xishuangbanma shallow ice core were analyzed and it was found that the variation of ion content showed a strong cyclical change, which reflected the characteristics of seasonal variation. The variation of ion concentration would indicate the change of climate and the change of precipitation There is a corresponding relationship with δ ~ (18) O, but δ ~ (18) O does not reflect the climatic changes of all kinds of ions.
