摘要: 在2007年4月、8月和10月三个时段内,分昼夜采集了23个气溶胶样品和7个新降雪样品,对样品中的可溶性离子进行了分析。结果表明,乌鲁木齐河源1号冰川(以下简称1号冰川)春、夏、秋三个季节气溶胶平均载量为86.22 neq/m3,分析显示1号冰川存在NH4HSO4和(NH4)2SO4气溶胶,并有少量NH4NO3气溶胶存在。气溶胶和新雪样品中可溶性离子成分变化趋势相似,气溶胶浓度升高,新雪样品的浓度也会有所升高,反之亦然。气溶胶和新雪中Ca2+、Mg2+、Na+、Cl-、K+的相关性很好,说明雪中这些离子的浓度基本能反映大气中的状况;对气相和颗粒相并存的NH4+和NO3-来说,雪中的离子浓度和大气中的离子浓度不相关。
