摘要

本文介绍了科米共和国中泰加半水文地貌松林中森林火灾后 Histic Podzols 的主要特性数据。在火灾后的土壤中,表土层厚度减少了 7.6 倍以上,枯落物密度增加了 6 倍,枯落物储量减少了 4 倍。火烧层(48%)和荚膜层上部的碳含量有所增加,从对照小区的 0.49% 增加到火灾后的 1.16%。据记录,野火后土壤中所有研究的痕量金属(铜--从 2.5 到 6.8 毫克 × 千克-1;锌--从 35.7 到 127.4 毫克 × 千克-1;镍--从 2.2 到 8.1 毫克 × 千克-1;铅--从 1.4 到 28.3 毫克 × 千克-1;镉--从 0.3 到 1.1 毫克 × 千克-1)都有积累。火灾的影响可追溯到大约 20-30 厘米的深度。火源因素对阿尔法和贝塔细菌多样性有重大影响。细菌对森林火灾的反应可分为孢子形成菌和革兰氏阴性菌比例的增加以及复杂的新陈代谢。

Wildfires’ Effect on Soil Properties and Bacterial Biodiversity of Postpyrogenic Histic Podzols (Middle Taiga, Komi Republic)
Data on the main properties of Histic Podzols in the pine forests of semi-hydromorphic landscapes in the middle taiga of the Komi Republic after forest fires are presented. A decrease in topsoil horizon thickness by more than 7.6 times, an increase in litter density by 6 times, and a decrease in litter stock by 4 times were observed in postfire soil. There was an increase in carbon content in the pyrogenic horizon (48%) and in the upper part of the podzolic horizon—from 0.49 at the control plot to 1.16% after the fire. The accumulation of all studied trace metals (Cu—from 2.5 to 6.8 mg × kg−1; Zn—from 35.7 to 127.4 mg × kg−1; Ni—from 2.2 to 8.1 mg × kg−1; Pb—from 1.4 to 28.3 mg × kg−1; Cd—from 0.3 to 1.1 mg × kg−1) in soils after wildfires was recorded. The effect of the fire can be traced to a depth of approximately 20–30 cm. A significant influence of the pyrogenic factor on the alpha and beta bacterial diversity was noted. The bacterial response to a forest fire can be divided into an increased proportion of spore-forming and Gram-negative species with complex metabolism as well.
