Abstract

The paper presents the measurements of illumination and surface temperature of plants in the pine and spruce plantations of the Solovetsky Archipelago. The difference in these values is estimated in several layers (at a height of 1.3 m, in the grass and shrub and moss-and-lichen layers) numerically (in absolute and relative values, the variability is calculated). The measurements are carried out with distance from the tree stem northerly and southerly. The higher variability of illumination in the spruce forest, its uniform vertical distribution at the level of the grass and shrub layer and the maximum variability at the moss-and-lichen layer are noted. The tree level plays an important role in thermoregulation in the lower layers of the spruce forest, and the moss-and-lichen layer ‒ in the pine forest. For spruce stands, a slight decrease in temperature from the canopy of the crown to the “window” both in grass and shrub and moss-and-lichen layers is representative. The authors observe a temperature rise in the pine forest in the moss-and-lichen layer both in relation to the grass and shrub layer and from the canopy to the “window”. An analysis of the wind speed variability is carried out in the crook-stem forest of betula tortuosa mixed with other species. These forest plantations are formed when intensive wind action, dominate along the seacoast, and play an important protective role. The measurements are carried out at different distances from the seashore ‒ up to 100 m from the border of the forest. The wind speed at this distance decreases more than 3 times ‒ on average from 1.72 to 0.48 m/s, and the amplitude ‒ by 2‒7 times.
