摘要 NH3作为大气中主要的碱性气体,在大气化学中扮演着重要的角色.为研究历史时期大气NH3含量,借以冰芯中NH4+浓度变化来反映大气NH3含量的变化.2003年在东帕米尔高原慕士塔格峰海拔7010m处钻取了一支长54.6m的透底冰芯,分析了该冰芯上部51.6m近百年来NH4+浓度记录.结果表明,慕士塔格冰芯中NH4+浓度自20世纪初突然降低后平缓过渡至1930s,其后缓慢增加,在1966/1967年略有下降后呈持续增长趋势,至1990s末达到最大.冰芯中NH4+浓度的增加与邻近气象站和北半球升温趋势相似,反映了温度对NH3排放的影响.慕士塔格地区大气中的NH3主要受中亚及周边地区排放源的影响.
