北极Ｓｖａｌｂａｒｄ群岛Ｌｏｎｇｙｅａｒｂｙｅｎ地区３条冰川８个雪坑样品的分析结果表明，该地区冰川表层雪中海盐离子Ｃｌ－和Ｎａ＋占主导地位，其浓度远高于其它离子，而陆源Ｃａ２＋在雪坑秋季污化层中浓度远远高于其它层位，可作为雪坑定年中秋季层位的标志。在季节变化上，海盐离子和ＳＯ２－４、ＮＯ－３在春季和夏季表现为高值，这与冬春季节北大西洋风暴和中纬度人类污染物远距离传输到北极有关，也与夏季局地海洋性气团、大气中氧化作用、光电作用和清除速率有关。同全球的边远地区格陵兰、南极和青藏高原比较，Ｌｏｎｇｙｅａｒｂｙｅｎ地区雪中离子浓度水平较高，特别是海盐离子浓度远高于其它地区。
The analysis of 8 snow craters from 3 glaciers in the Longyearbyen area of the Arctic Svalbard archipelago shows that the concentrations of sea salt ions Cl- and Na + predominate in surface glaciers of the glacier at concentrations much higher than those of other ions. However, the terrigenous Ca2 + The concentration in the stratum is much higher than other strata, which can be used as the symbol of the mid-autumn stratum in the snow pit. In the seasonal variation, sea salt ions and SO2-4 and NO-3 showed high values in spring and summer, which were related to the long-distance transmission of North Atlantic storm and mid-latitude human pollutants in the winter and spring to the North Pole, Marine air mass, atmospheric oxidation, photoelectric effect and clearance rate. Compared with the remoteland areas of Greenland, Antarctica and Qinghai-Tibet Plateau in the world, the Longyearbyen area has a higher concentration of snow ions, especially the sea salt ion concentration is much higher than other areas.
