摘要

本文旨在研究欧洲北部最大的纸浆和纸张生产企业--"Syktyvkar Timber Processing Complex "股份公司--产生的气体排放对绿苔松林中主要矮灌木越橘和蓝莓叶片元素组成(N、S、C、P、K、Ca、Mg、Na、Al、Fe、Mn)的影响。经鉴定,2009 年生长在背景区和污染区松林中的蓝莓和越橘叶片的灰分元素质量分数平均值相似。背景松林中矮灌木叶片中灰分元素的含量高于 2018 年从影响区采集的叶片中的含量。在背景区和污染区,蓝莓叶片中灰分元素质量分数的平均值都比越橘叶片中灰分元素质量分数的平均值高出 1.5 倍。矮灌木叶片中的元素含量与排放源的距离没有规律性变化。2009 年和 2018 年矮灌木叶片中硫含量的差异在误差范围内。在距离排放源不同距离的松树林中,蓝莓和越橘叶片中氮元素的质量分数值没有发现明显差异。在两个观测期内,越橘叶片中的氮含量都明显低于蓝莓叶片中的氮含量。在2009年和2018年期间,蓝莓叶和越橘叶中的总氮含量没有明显差异。

Elemental composition of Vaccinium vitis-idaea и V. myrtillus (Ercaceae) leaves in green moss pine forests under aerotechnogenic pollution in the Komi Republic
The paper aims at the impact of aerotechnogenic emissions from the largest in the European North pulp and paper production enterprise, namely JSC «Syktyvkar Timber Processing Complex», on the elemental composition (N, S, C, P, K, Ca, Mg, Na, Al, Fe, Mn) of lingonberry and blueberry leaves as the dominant dwarf shrubs in green moss pine forests. The leaves of blueberry and lingonberry growing in pine stands both in the background and contaminated areas were identified to have similar average values of the mass fraction of ash elements in 2009. The content of ash elements in the leaves of dwarf shrubs from the background pine forests was higher than that in leaves collected from the impact zone in 2018. The average values of the mass fraction of ash elements in blueberry leaves were found to access those in lingonberry leaves by 1,5 time both in the background and contaminated areas. There was no regular change in the content of elements in leaves of dwarf shrubs with distance from the source of emission. The differences in the sulfur content in leaves of dwarf shrubs for 2009 and 2018 were within the error limits. No significant differences were found in the values of the mass fraction of nitrogen in blueberry and lingonberry leaves for pine stands located at different distances from the emission source. The nitrogen content in lingonberry leaves was significantly lower than that in blueberry leaves for both observation periods. There was no significant difference in the total nitrogen content in blueberry and lingonberry leaves between 2009 and 2018.
