Abstract—

The dynamics of snow depth and snow composition in the period of 2013–2018 has been discussed. The annual snow cover dynamics is characterized by the alternation of high and low values. The highest values were typical for winter of 2012/2013 followed by a decrease in 2013/2014. The leading role in the snow cover distribution belongs to the elementary landscape position within the geochemical landscape. Over the research years, the water equivalent of snow cover has been characterized by a bicarbonate–calcium composition. Contents of minor components have been generally of the same order of magnitude as the results obtained for the South Taiga landscapes. Some excess of individual components in the snow water in comparison with Мeshchera and Baikal landscapes, taken as a background, is due to the proximity of the studied geochemical landscape and the M-10 main road (Moscow–St. Petersburg). It is assumed that a relatively high Ca content in the snow water of the superaqueous landscape is related to a possible Ca arrival from external meadow–marsh carbonate soils boiling from the surface. Sulfate ion has been found out to play a key role in the diagnosis of atmogeochemical pollution which has been partially established for the studied landscapes.

从Klyazma河上游的地球化学景观看，雪深和积雪的长期动态

摘要-

讨论了2013-2018年期间积雪深度和积雪的动态。年度积雪动态的特征是高值和低值交替出现。最高值是2012/2013年冬季的典型值，随后在2013/2014年有所下降。在积雪分布中的主导作用属于地球化学景观中的基本景观位置。在过去的几年中，积雪的水当量以碳酸氢钙和钙的成分为特征。微量成分的含量通常与南大河针叶林景观获得的结果数量级相同。与作为背景的Мeshchera和贝加尔湖景观相比，雪水中的某些单独成分过量，这是由于所研究的地球化学景观和M-10主干道（莫斯科–圣彼得堡）之间的距离近。假定超水景观的雪水中较高的Ca含量与可能从表面沸腾的外部草甸-沼泽碳酸盐土壤中Ca的到达有关。已发现硫酸根离子在大气化学污染的诊断中起着关键作用，而这种化学作用已部分地针对所研究的景观而建立。
