| 摘 要： | 为研究山岳冰川积雪中NO3-与粉尘记录之间的联系,利用2003~2005年间新疆天山乌鲁木齐河源1号冰川东支积累区的雪样,分析了雪层中NO3-与不溶微粒的对应关系.研究发现,沙尘活动季节初期,表层雪中NO3-浓度与不溶微粒浓度呈正相关,而与其平均粒径呈负相关,表明NO3-可以通过吸附在粉尘细颗粒表面远距离传输.雪层剖面中NO3-浓度峰值与污化层之间的相对位置在冬半年可基本保持稳定,但夏半年以淋溶作用为主的后沉积过程,会强烈改造NO3-与粉尘记录之间的联系. |

| Abstract: | In order to investigate the relationship between nitrate(NO3-) and dust record in snowpack of mountain glaciers,based on the snow samples collected at the east branch of Glacier No.1 at the Headwaters of Urumqi River,eastern Tianshan Mountains from 2003 to 2005,correlation between nitrate and insoluble microparticle was analyzed.During the early period of dust season,nitrate concentration was positively correlated with insoluble microparticle concentration,and negatively correlated with mean diameter of ins... |
