摘要

摘要森林火灾是全球范围内最严重的骚乱之一。森林火灾影响生物多样性和生物地球化学循环，在大气化学过程和全球碳循环中发挥着重要作用。以萨马拉地区的热原景观为例，综述了热原土壤形成过程中重金属含量在土壤剖面内的积累规律及其迁移规律。在地表森林火灾的情况下，所研究的热解后土壤的特征是Opyr热解层中镉、镍和锌含量增加。相比之下，与控制树冠森林火灾相比，所有分析的重金属含量都有所下降，这表明活性元素排放到大气中。

Estimation of heavy metals content and regularities of its migration within a soil profile during pyrogenic soil formation in the context of the Scotch pine forest in Togljatty city

Abstract Forest fires are among the most significant disturbances on a global scale. Affecting biodiversity and biogeochemical cycles, forest fires play an important role in atmospheric chemical processes and the global carbon cycle. Using the example of the pyrogenic landscapes of the Samara region, this article reviews changes in the accumulation regularity of heavy metal content and its migration within a soil profile during pyrogenic soil formation. In the case of surface forest fires, the studied postpyrogenic soils are characterized by increased cadmium, nickel and zinc content in the Opyr pyrogenic horizon. In contrast, the content of all analyzed heavy metals decreases compared to the control for crown forest fires, indicating active element emissions into the atmosphere.
