  • 摘要: 通过2004-2007年在天山乌鲁木齐河源1号冰川积累区采集的136个表层雪样品,分析了山岳冰川表层雪中主要含氮离子(NO3-与NH4+)的季节变化特征.结果表明,湿季表层雪中的含氮离子浓度一般比干季高,由于湿季NO3-与NH4+的输入量与流失量均较大,因此湿季浓度波动比干季更强烈.气溶胶与表层雪中的NO3-浓度在干季存在显著的相关性,在湿季相关性差,而NH4+浓度则表现出相反的特征.表层雪中含氮离子浓度大多高于极地和青藏高原,原因在于本研究区受粉尘输入与人类活动的影响较大.
    Abstract: To investigate the seasonality of nitrogen-containing ions in surface snow of mountain glacier, 136 samples of surface snow were collected in a weekly frequency from 2004 to 2007 in the accumulation zone of Glacier No. 1 at the headwaters of Urumqi River, eastern Tianshan Mountains, and were analyzed for NO3- and NH4+ concentrations. The results indicate that the concentrations in wet seasons (from April to October) were higher than those in dry seasons (from November to March). Strong fluctuation of concentrations was observed in wet seasons due to significant input and output of nitrogen-containing ions in wet seasons. Correlation between NO3- concentrations in aerosol and surface snow is much higher in wet seasons than that in dry seasons, while correlation for NH4+ is the opposite. Concentrations of NO3- and NH4+ in the sampling sites, which are affected by dust transportation and anthropogenic activities, are usually higher than those in Polar Regions or Tibetan Plateau.
