Abstract The article presents the results of studies of the agrophysical properties of the zonal soils of Central Yakutia formed under the line of larch of different-level-cowberry. As human intervention in forest ecosystems increases, the fragile ecological balance of the existence of taiga-alasny permafrost landscapes, reflected in the properties and regimes of zonal soils, changes. Changes in the agrophysical properties of frozen soil directly affect the hydrothermal regime of the soil and, accordingly, the plant composition of the ecosystem. The obtained materials show a decrease in fertility and deterioration of the properties of frozen stick saltwater soils, their compaction and desiccation under the influence of ploughing during livestock crossing within forest between spaces. Destruction of ground vegetation reduces the natural thermal insulation of the frost and leads to an increase in the depth of seasonal soil weeding by 25%. The total anthropogenic impact leads to the destruction of taiga ecosystems and the degradation of the permafrost in Eastern Eurasia.
