根据2004年11月至2005年10月在天山乌鲁木齐河源1号冰川积累区采集的雪坑样品研究发现,雪层中NO-3平均浓度存在季节性变化特征,湿季(4~10月)的NO-3浓度明显低于干季(11月至次年3月)。特别是在春季,在雪层上部出现的浓度峰,经过夏季淋溶改造,稀释并合并为稳定的浓度峰;雪层中各浓度峰普遍处于向下迁移的过程中。在后沉积过程中,距底部附加冰70~80 cm附近的雪层处存在一个过渡层,上部变化强烈,下部相对稳定;强淋溶期可以使NO-3溶质含量减小20%~60%。

Based on the snowpit samples collected at the accumulation zone of Glacier No.1 at the headwaters of Urumqi River in the Tianshan Mountains from November 2004 to October 2005, nitrate (NO-3) concentration in snowpacks is analyzed. Seasonality is displayed for the mean NO-3 concentrations in snowpacks, and the concentrations are higher in the dry season (from November to March) and lower in the wet season (from April to October). At the upper section of snowpacks, the spring-formed NO-3 concentration peaks  are  diluted significantly in the summer, according to the elution effect; for the whole snowpacks, the NO-3 concentration peaks relocate downward. In the vertical profile of snowpack, a transition layer appears at a distance of 70~80 cm to superimposed ice layer; the elution effect above the transition layer is much stronger than that below, and the concentration above the layer is higher than that below. With 20%~60% loss of content during the strong elution period in the postdepositional process, the environmental information is recorded in the ice.
